Yay, WiPhone!

Be cautious charging the WiPhone on a Xiaomi Mi Power Bank 3 Pro

xopr's WiPhone broke down: his guestimates are that the device in USB-A port 1 that supported adaptive charging might bring the second USB-A port to 9V or 12V (out of spec), which in this scenario will fry the CP2104 USB-UART chip when you would plug it in second, no matter how short the time frame would be.

custom firmware

you can use the ACKspace modified firmware by setting https://ackspace.nl/WiPhone/WiPhone.ini into the ota.ini file (or via the telephone) Current applied patches:

LoRa 868MHz
ackspace.nl fake NAPTR (hardcoded IP)
fix fiddly unlock (mentioned here)

Work in progress:

LoRa menu (currently crashes the phone, don't use)

notes

read documentation here
report bugs at https://github.com/ESP32-WiPhone/wiphone-firmware/issues
enable/disable automatic firmware settings at Menu » Settings » Firmware settings
before you use LoRa, make sure to edit Hardware.h, look for RF95_FREQ and set it to 868MHz for EU:

#define RF95_FREQ 868.0 (See this (somewhat sparse) issue)

enable UDP by adding u=UDP_SIP to an account in data/sip_accounts.ini (not yet tested)

Get started

download source code
run V="0.8.30"; unzip WiPhone-$V && rm -fr WiPhone && mv WiPhone-$V WiPhone
open WiPhone/WiPhone.ino using Arduino
once: set up IDE (see documentation for details):
- Open preferences (CTRL+,) and add https://wiphone.io/static/releases/arduino_platforms/package_WiPhone_index.json (comma separated) into Additional Boards Manager URLs
- go to Tools » Boards » Board Manager and install WiPhone
- Arduino option Tools » ESP Sketch Data Upload: download ESP32FS-1.0.zip into the ~Arduino/tools directory with mkdir -p ~/Arduino/tools && unzip ESP32FS-1.0.zip -d ~/Arduino/tools
- TODO: esptool.py serial: sudo pip install pyserial (check your default python version)
Select Tools » Boards » Wiphone » Wiphone arduino
compile with (CTRL+r)

custom mods

command line build

The provided repo contains several patches and a semi-automated build/upload process to create your own custom binary (without opening the Arduino IDE) This includes:

caret cursor color fix
lockscreen fix (mentioned here as well)
LoRa 868MHz, menu is WIP
ackspace.nl fake NAPTR (hardcoded IP)
loudspeaker fix (mentioned here)

5V injector

To charge the Wiphone (with 5V, including charging indicator), without using USB (since xopr's UART is broken), he soldered 2 cables with female dupont ends to the 5V rail (not VBUS). With troubleshooting, he also noted some useful pads/components, more or less reversed engineered: File:Wiphone testpads components.svg

Here is the result

Ground on the bottom pad indicating "-" 5V on the left side of the "big" resistor above the right pogo header (not yet done in the picture) Dabbed in hot glue on the solder joints and strategically slightly right/above the center polycarbonate bridge (not in picture)
Wifi antenna cover just fits on top. Dabbed in hot glue: strategically slightly right/above the center polycarbonate bridge
Female dupont connectors fit nicely through the QWIIC slot on the LoRa daughter board.

Ze ondersteunen 4 SSID's per band, en er is out-of-the-box-support voor WPA2-enterprise en VLAN om het netwerk te kunnen segregeren van testnetwerk en actief netwerk. xopr stelt voor om er 1 in de slACKspace en 1 in de stACKspace te plaatsen voor goeie dekking tot in de tussenruimte en load-balanced in de hACKspace. Als suggestie kan er 1 MESH variant gekozen worden welke geschikt is voor buiten (in geval van kleine events) en welke komt met verwisselbare antennes. ¹⁾ om niet onder te doen voor ons huidige netwerk is minimaal een router en 1 accesspoint nodig (gezamelijk ongeveer €150,-)	link mesh variant	xopr

synopsis

Vanaf heden (9-7-2022) is er elke:

vóórlaatste zaterdag tussen 00:00 en 23:59 (de hele dag dus) een hacksessie evenement.

Het is dan de bedoeling om deze paar uurtjes exclusief te gebruiken om aan je project of willekeurige hack te werken, al dan niet als groepje. Gezien de huidige situatie is een virtuele space ingericht on als nog samen te werken zonder fysieke aanwezigheid te hoeven hebben. Je hoeft niet per se mee te doen, maar dit is natuurlijk hét moment om verder te komen met projecten.

Heb je een idee, maar weet je niet hoe je het kunt uitwerken? Vraag het dan op de mailinglijst, IRC of Telegram groep.
Kom je een onderdeel te kort? Mail het bestuur.
Ben je op zoek naar inspiratie? Kijk eens op patches welcome of bij de geparkeerde projecten en voeg jezelf gewoon toe aan je nieuwe favoriete project
Is iets, maar dan ook iets niet duidelijk? Gewoon vragen!

This project ties strongly with the MQTT setup (to connect to the SpaceAPI) as it uses Tasmota^[1] on ESP devices for feature bang and ease of use.

Note that you're more than welcome to add any sensor (or actuator) that you might see fit for our hackerspace. Think: 3D printer nozzle temperature or filament weight, outside radiation, air quality, motion sensing, window opener and the likes; this project is proof anyone that can handle a screwdriver and PC can do this.

synopsis

Create a modular repository of sensors and outputs to keep an eye on temperatures (and/or other stuff), especially for monitoring the server room, and optionally, the [sl|h|st]ackspace(s), including the space state switch.

intro

After some iterations of the Space state switch and some versions of the Spacestate indicator, some different types of temperature sensors, it was time to make it easy on ourselves: switch to MQTT and use Tasmota^[1].

In most cases, an off-the-shelf ESP device will suffice, but since not all devices are not galvanically isolated from mains, it's more practical to use an ESP-12 PCB for things where contacts are bare (like the Space state switch).

Here are the steps to setup such a device

configuring a spacestate sensor from scratch

Most of this (apart from the MQTT configuration) only applies to the Spacestate sensor board (see image); it will setup a pinout template that matches the board.

Under Configuration, click Configure Other
Paste this template: {"NAME":"ACKsensor","GPIO":[0,0,0,0,0,0,0,0,1,0,0,0,1,1],"FLAG":0,"BASE":18} and check Activate
Fill in Device Name (ACKtemp or ACKstate) and Friendly Name 1 (Space state switch or leave as is)
Save (will reboot)
Click Configure Module
Make sure Module type is ACKsensor (0)
Set functions for GPIO17 (ADC), GPIO16 (Typically Switch 1 or Button 1) and GPIO12 (DS18x20 which is connected to 3.3v using ~4k7 pull up) ^[2]
Save (will reboot again)
Click Configure MQTT
Set Host (192.168.1.42), User (temperature or spacestate), Password (currently, only xopr knows these passwords), Topic (temperature, switch or spacestate) and Full Topic (ackspace/hackspace/%topic%/%prefix%/)
Save (will reboot yet again)

notes and troubleshooting

GPIO16

Note that this pin is special (it lives on a separate register internally, but more important, its internal pull resistor is to ground (pull-down) ^[3]^[4]^[5]

ADC/GPIO17

Note that the analog in is 0-1V maximum; use a voltage divider to limit its input.^[6] and ^[7]

space state

To read a switch without having a corresponding relay one has to remember the default switch action is TOGGLE, which can be used in traveler-system (hotelschakeling) style: one can turn the light on with switch 1, turn it off with switch 2 (software) and turn it on with switch 1 again while the switch physically is in a different state. To change the behavior of the switch, use switchmode^[8]:

switchmode 1
restart 1

Note that if you need the reverse (switch connects to poweroff), you need switchmode 1. Also note that restart 1 is needed to store the configuration.

multiple switches on the spacestate sensor

By default, one can use a single switch/button without a relay set. If you want to provide MQTT state for multiple switches without having corresponding relay outputs, you need some rule magic;^[9]

Rule1 ON switch1#state DO publish ackspace/hackspace/%topic%/stat/RESULT {"POWER1":"%value%"} ENDON
Rule2 ON switch2#state DO publish ackspace/hackspace/%topic%/stat/RESULT {"POWER2":"%value%"} ENDON
Backlog Rule1 1; Rule2 1

other devices (switches)

Note that the space has a modified sonoff POW (old revision) that allows switching with a regular toggle switch while able to monitor the power usage. It uses the following template: {"NAME":"Dangerous POW","GPIO":[32,160,0,0,0,2592,0,0,224,2656,2688,288,0,0],"FLAG":0,"BASE":6} Note that while the GPIO is 5V relative to GND, it most likely is 225V above earth potential: insulate well and never connect it to your PC.

calibrating POW module

To calibrate a POW module (like in the hackcorner), you need the following^[10]:

Multimeter (for measuring mains voltage)
Resistive load (higher=better, like the 500W SMD rework station)

Steps:

monitor mains voltage
go to the sonoff console tab of the device
turn on the hot air station and crank up the dial
input the following (adjust the voltage and current accordingly)

for current, you use the formula: P/U*1000 = 500/227*1000 = in this case

VoltageSet 227
PowerSet 500
CurrentSet 2202.64
restart 1

recovery

When a device doesn't respond or won't connect to wifi, you might need to trigger recovery mode^[11] by:

power it off for 30 seconds
power on 7 times with less than 10 second interval

Note that this only works if SetOption65 is 0 (which one would have disabled if brown-outs occur often.

connecting UART

use 3.3V logic to be safe

Run terminal client in 56k 8N1: minicom -D/dev/ttyUSB0 -b57600 -os And make sure Hardware Flow Control is off: choose Serial port setup, f (to open the configuration menu, press Ctrl+a, o)

Uboot env

After pressing space to interrupt (within 1 second) you get:

Please choose the operation: 
   0: Load system code then write to Flash via Serial.
   1: Load system code to SDRAM via TFTP.
   2: Load system code then write to Flash via TFTP.
   3: Boot system code via Flash (default).
   4: Enter boot command line interface.
   7: Load U-Boot code then write to Flash via Serial.
   8: System Load UBoot to SDRAM via TFTP. (hidden in menu)
   9: Load U-Boot code then write to Flash via TFTP.

in the command line interface (4), you can continue booting with bootm bc050000

MT7621 # printenv
bootcmd=tftp
bootdelay=1
baudrate=(57600)
ethaddr="AA:BB:CC:DD:EE:FF"
ipaddr=192.168.1.1
serverip=192.168.1.2
stdin=serial
stdout=serial
stderr=serial

root password

The short answer is: it's on a "factory" partition in the flash, most likely located at 40000_HEX.

How to get root without copying the flash (only using serial):

within the boot sequence at 3/4 of the log: search for "factory", most likely it reads something like:

[ 2.290000] 0x000000040000-0x000000050000 : "factory"

remember 40000_HEX (and add 20_DEC so it becomes 40014_HEX
reboot (either press and hold the reset button >4s or pulse X2 pin 2 and 7
press space in the serial monitor (you have 1 second if it says Press space to enter the bootloader... ).
press 4
and type spi read 40014 10
- it will return something like this:
read len: 16

38 4d 6d 42 52 32 35 6d 73 6d 0 0 0 0 0 0
use an online converter or run this in a javascript console:
"38 4d 6d 42 52 32 35 6d 73 6d 0 0 0 0 0 0".split(" ").filter(n=>n!=="0").map(n=>String.fromCharCode(parseInt(n,16))).join("")

You can also retrieve it from the bin file: dd bs=1 skip=$((0x40000+20)) count=10 if=ixrouter.bin 2>/dev/null | tr -d '\000'

Oh by the way, it's 8MmBR25msm

Note that when a sim card is present, it will connect automatically and be the primary route to internet.

go to network interfaces and edit WWAN
Protocol: DHCP client, switch protocol and set a nice hostname. Save & Apply
click Connect
if this doesn't seem to work (no RX data), either reboot, go to System Software and install (filter for) uqmi
login with SSH and type the following:

/sbin/uqmi -d /dev/cdc-wdm0 --set-device-operating-mode offline

/sbin/uqmi -d /dev/cdc-wdm0 --set-device-operating-mode reset

wait 20 seconds

/sbin/uqmi -d /dev/cdc-wdm0 --set-device-operating-mode online

/sbin/uqmi -d /dev/cdc-wdm0 --set-autoconnect enabled

enable wifi AP

By default (and using the cloud config generator), the U-blox wifi device is set to station (client) when booting. The script is at /lib/wifi/ublox.sh and it read properties generated via ixrouterconf2uci (not sure whether it's possible to trigger the correct data via the ixconfig). The driver is Marvell WiFi-Ex Driver (cfg80211)

To prepare for accesspoint mode, run the following:

uci set wireless.ap_lan_dev.channel='11'
uci set wireless.ap_lan_iface.ssid='ACKspaceWifi'
uci set wireless.ap_lan_iface.key='Nope. Nope nope nope nope nope.'

To switch, do this:

uci set wireless.ap_lan_dev.disabled='0'
uci set wireless.sta_wan_dev.disabled='1'

To apply the new wifi settings, run /etc/init.d/network reload and to permanently store them, use uci commit

spacenet

Not possible with the current (closed) driver+firmware

Short version: remove wpad-mini and install wpad. Rest might be command line settings only since the web interface for wifi doesn't play nice with the current setup.

setup openVPN (automatically connects)

Note that this will have OpenVPN connect automatically and DNS might give problems. If so, select both WAN and VPN in the second-to-last step.

To connect to the ACKspace VPN (tun), change the interface:

go to Network Interfaces and Edit VPN
under Physical Settings choose Custom interface: tun+
Save & Apply
go to Network Firewall and add a Zone:
VPN (vpn) masquerading (possibly also MSS clamping)
Save & Apply
locate your ackspace.ovpn file and make sure it contains the following line:
auth-user-pass /etc/openvpn/login.conf
copy the file:
scp ackspace.ovpn root@192.168.27.1:/etc/openvpn/ackspace.conf
SSH into the router and create the following file containing username and password on a separate line: /etc/openvpn/login.conf
/etc/init.d/openvpn restart
finally, in Luci, go to Network Firewall -> Zone LAN and click Edit
switch Allow forward to destination from WAN to VPN
Save & Apply

These modified scripts restore some of the functionality that seems to be absent when not using the ixagent daemon.

custom wifi monitor. When 4G/LTE is enabled, the signal quality will display the cell strength (Reference signal received quality).

alternative power

It is possible to power the router with a USB-C powerbank for off-the-grid usage, ideal for a hackers on a bike tour. All you need is:

a USB-C powerbank that supports >=12V
USB-C to USB-C cable ZY12PDN USB-C Fast Charge Trigger Poll Detector, set to highest voltage possible (but lower than 24V)
removable screw terminal connector (two or [1] pins) (see the green connector in this picture)

Tested on a fully charged Xiaomi Mi Powerbank 3 (20Ah) and had an uptime of 26:45h.

spacenet

Alternative power combined with a Unifi PoE hack, this could be used for a mobile spacenet. xopr's "event" accesspoint has spacenet on VLAN 6; it's easier to add a VLAN than to reprovision the accesspoint every time:

in Network > Switch
- Add, 6 off, tagged, tagged, tagged, tagged, off, tagged
- Save, apply
in Network > Interfaces
- Add new interface...
- Name: ACK
- Protocol: Static
- Covering: VLAN interface eth0.6
- Next >
- Setup DHCP server (first!)
- IPv4 192.168.6.1
- Netmask: 255.255.255.0
- Advanced: Bring up on boot
- Create firewall zone: LAN
- Save & apply

Disable regular wifi with uci set wireless.sta_wan_dev.disabled='0' and apply with /etc/init.d/network reload. (TODO: verify that it's back up after reboot)>

Description	Arduino Space State indicator for home
Picture
No project picture! Fill in form Picture or Upload a jpeg here

My verry fancy space state indicator broke down, so i tried to recreate it using stuff i had laying around, which was a Wemos D1 R1 arduino clown to which i added a shield with a RGB led. There is also an output to drive a beeper that sounds if the space state changens to 'Open'

Pin Numbering on this board is a bit confusing but this how i did set it up.

Led-Red	pin 7
Led-Green	pin 6
Led-Blue	pin 5

(In this version i did not hookup the beeper anymore, although the software still supports it) The RGB Led is hooked up to the pins using 100 Ohm resistors which offers adequate current to give a clear indication.

In the code provided below the login credentials for your personal wifi router have to be setup. The flashy light sequence "Das blinken das lichtes| shows during startup if everything goes well. The following startup stages are implemented for diagnostics

During startup	All colors will flash once
During WiFi login	Blue Color flashing Red until login was sucsesfull
Running	Red, Green or Yellow depending on the SpaceState or Dark on server error.

Eventualy the Space indicator should show eighter Green for OPEN or Red for closed. If there is a problem in requesting the actual space state, the indicator shows Yellow. And it will remain dark if the server could not be connected.

The SpaceState is requested each 15 seconds, indicated by a show blue flash on the indicator

You can copy the code into a Arduino sketch Select for the board LOLIN(WeMos) D1 R1

If you can't find this board in your Arduino IDE most likely your setup has no support for ESP32 yet. In this case click on File->Preferences And add the following line to 'Additional Boards Manager' https://arduino.esp8266.com/stable/package_esp8266com_index.json

Then tools->Board->Board manager And perform a update. Afther this, you'd select the WeMos board and compile the sketch

synopsis

Read sensors and do some space automation using the Message Queuing Telemetry Transport protocol.

Currently, you can see the solder table powerstrip connected in the power graph.

current status

The MQTT server can be found at 192.168.1.42, via the regular port (1883) as well as the TLS port (8883) and secure websockets at port 443 (subject to change). To connect securely, use the certificate authority chain

There is a sonoff Pow wifi switch in the space, (not yet) connected to a powerstrip near the soldering table (in a brown plastic case with a toggle switch on top of it).

The idea is to gradually add them to every power strip so we can:

measure (over)current
switch them off centrally if the space is closed (or notify the user that they are still on, for example, 3D printers).

It currently runs a modified version of the famous Tasmota firmware (the modification allows dangerous GPIO whist using the energy measurement).

NOTE: the switch is built in a box with an external toggle switch. This switch has potentially 240v on its contacts so don't open it and touch the contacts when it is plugged in! Also don't connect both serial and mains; things will break.

You can toggle it via wifi on h1r-2067.lan (subject to change), or by issuing a mosquitto_pub -L 'mqtt://username:password@192.168.1.42/ackspace/hackspace/h1r/cmnd/POWER' -m 'TOGGLE'

The proposed topic hierarchy is as followed: [base]/[room]/[device]/[prefix]/[type] Where both [prefix] and [type] come from Tasmota's topic definition (tele stat cmnd and SENSOR STATE RESULT POWER LWT respectively). Try to use all-lowercase names (with an exception of the last bit, often in CAPS),

At least ackspace, common, outside and services are supported as base. Services are a bit special; choose a category for room (i.e. voip) and an identifiable name for device (i.e. freeswitch); see the extra examples list of topics further below.

In the future, we can extend this to support something like offsite and the names of participants.

Since ACKspace doesn't have rooms at different levels, the second hierarchy level consist of the room, like slackspace, hackspace and stackspace. device is the name of the device (similar as Tasmota's %topic%) like spacestate, temperature, hackswitch or fluorescent1.

At least the following topics will be implemented first:

ackspace/hackspace/spacestate/stat/RESULT (json power state)
- ackspace/hackspace/spacestate/stat/POWER1 (string power state)
- ackspace/hackspace/spacestate/tele/STATE (json state at interval)
ackspace/hackspace/temperature/tele/SENSOR (json telemetry data)
outside/courtyard/barbecue/tele/SENSOR (json telemetry data)

Extra examples:

services/voip/freeswitch/tele/STATE (FreeSWITCH specific data, like caller id)
services/network/bandwidth/tele/SENSOR (Current network bandwidth usage)
offsite/xopr/whatever/topic/he/pleases (details might be negotiated for ease of use)

Telephone system:Number lookup

This script uses mod_cidlookup combined with a custom php page. It tests the number against a SQLite database, several reversed number lookup websites, the national telecommunications authority database and a coarse array of areas of the world, which are called in order of granularity. The script can be called both on outgoing and incoming calls

or use a custom built File:Fartnet.gz to listen as a fake artnet endpoint (source here) to get this:

connecting UART

New firmware has a script that install openssh-server, so UART is no longer required to get things up and running!

/!\ don't connect PoE and UART, you will fry the main board; there is a 43v difference in ground planes.

use 3.3V logic to be safe

For best results (prevent console glitches and boot loops), disconnect UART V_IN and connect regular (micro) USB power

Run terminal client in 56k 8N1: minicom -D/dev/ttyUSB0 -b57600 -o And make sure Hardware Flow Control is off: Ctrl+a, o, choose Serial port setup, f

install secure shell daemon

Connect to Minew AP (wifi).

Login with default credentials, if it doesn't work; hold reset pin atleast 30 seconds while booting device.

Update firmware (see below).

Configure Minew to use your network with wifi or ethernet in the Network tab.

Take note of IP address in Status tab.

Disconnect from Minew AP.

Visit http://thingoo/cgi-bin/installssh (you might need to fill in its IP address).

After it is installed you should be able to SSH to the device!

~~gain root access by #updating firmware and run the following:~~

~~opkg update opkg install openssh-server vi /etc/ssh/sshd_config~~
~~make sure PermitRootLogin yes is set for (ch)easy login~~

/etc/init.d/sshd restart

updating firmware

The current version at the time of writing is v3.2.2

login to the router (http)
go to tab Other (the last tab)
scroll to FIRMWARE UPGRADE
- either choose USB and put the firmware as thingoo-upgrade.bin on the root of a USB stick (case sensitive)
- or choose put the firmware on a (local) webserver and fill in its URL (root:kakhoofd). Case sensitive: chances are, you have to rename the file thingoo-upgrade.bin!

root password

The password as of yet is unknown (you can flash other firmware with a known/empty password so no real problem).

The shadow hash is $1$Sevciuy0$CRuXyRAOWeathkwz1T00I1 (md5crypt) and is not in the 13GB Rocktastic12a password list, nor is it found by hashcat -O -a 3 -m 500 hash.txt -1 ?l?u?d ?1?1?1?1?1?1?1 --increment, which means, it either consists of punctuation marks/spaces (?s), or is 8 bytes long or longer, which the latter would take roughly a week on 8 × RTX3090s to verify.

troubleshooting

ModemManager

Some Linux distro's hijack the serial port for modem usage; when you're experiencing problems, try and disable the ModemManager service:

systemctl disable ModemManager.service
systemctl stop ModemManager.service

Hardware flow control

If your serial is working intermittently, make sure Hardware flow control is off; for minicom it's: Ctrl+a, o, choose Serial port setup, f

If your terminal glitches or if you have boot loops, make sure you have a proper power supply and don't mix several supplies (i.e. PoE, USB, UART)

Description	Workbench on-the-go
Picture

This project page is more of a reference to xopr's notes: About 4-4.5 years ago I needed to take measures to turn my guest bedroom/workshop/storage into a babyroom. To still be able to do some tinkering, I've decided to create a portable electronics workbench with small and fairly cheap tools:

170W laptop power brick
DSO138 oscilloscope
DPS3005 30V 5A lab power supply
TS100 soldering iron
multimeter
some banana plug cables
box with electronic hardware and dev boards
various pliers and screwdrivers
locks and handlebar from an old hardware case from back when it was popular to walk around with a desktop-pc-in-suitcase

I've designed the bench using Sketchup with 9mm MDF walls in mind.

Layout with measurements: blue is base, green is sliding top
Closed bench
Opened bench

The model I've created to derive the measurements from is here (zip)

notes

the design is derived from measurements of the plastic compartment box on the back, the laptop PSU, multimeter and tools I had at hand or found useful
everything that needed to be bolted down has been done with countersunk bolts to prevent obstruction or scratching the underlaying surface
the "rubber" band that holds the tools and storage box came from a fabric or textile shop and is stapled onto the wood
the left door has to close before the right, and will be held in place by the work area which in place is held closed by the lid of the sliding mechanism.
when the sliding part is pulled out, it can rest on top of the base by placing it a bit forward (on the thicker walls that provide the sliding mechanism in the first place)
paint MDF; use a lot of paint to reinforce the material since (hardware store quality) MDF is really soft. Note that you might have to accommodate for the thickness of the paint layer
it actually might be way better/stronger to use 9mm triplex/multiplex
keep the saw blade thickness in mind when slicing up the wood
note that there is no storage room underneath the sliding part (a couple of sheets of instructions at most)
the bench is designed with compactness in mind; it takes some time and effort to set it up and tear it down so it's not a "quick bench"
