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"

This project ties strongly with the MQTT setup (to connect to the SpaceAPI) as it uses Tasmota 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.
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 (
ACKtemporACKstate) and Friendly Name 1 (Space state switchor leave as is) - Save (will reboot)
- Click Configure Module
- Make sure Module type is
ACKsensor (0) - Set functions for GPIO17 (ADC), GPIO16 (Typically
Switch 1orButton 1) and GPIO12 (DS18x20which is connected to 3.3v using ~4k7 pull up), see GPIO-Conversion for details - Save (will reboot again)
- Click Configure MQTT
- Set Host (
192.168.1.42), User (temperatureorspacestate), Password (currently, only xopr knows these passwords), Topic (temperature,switchorspacestate) and Full Topic (ackspace/hackspace/%topic%/%prefix%/) - Save (will reboot yet again)
details and troubleshooting
ADC/GPIO17
Note that the analog in is 0-1V maximum; use a voltage divider to limit its input (also see the Tasmota ADC and calibration/tuning pages).
multiple switches on the spacestate sensor
If you want to provide MQTT state for multiple switches without having corresponding relay outputs, you need some rule magic; see this rule section to do so.
recovery
When a device doesn't respond or won't connect to wifi, you might need to trigger recovery mode 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.

| Vacuumkamer + pomp | € 129.99 | Voor projecten met hars en siliconen. Ter vervanging van de vacuumkamer wat vroeger door Valium werd voorzien | link | Adnub | |
| PoE switch | €32,- (€39.40,- voor Gbit) | Voor experimenteren/testen van Telefoons, IP cams en PoE in het algemeen | 100Mbit & Gbit | xopr | |
| Vriezer voor pizza. | €124 | De pizzaspace van Nederland heeft 24/7 access nodig tot pizza! Eventueel kan Ackspace pizza te koop aanbieden aan de deelnemers? | link | Adnub | |
| Eigen Ackspace satelliet | +- €1,000,000.00 | Eigen satelliet in orbit voor onafhankelijke communicatie en monitoring van de wereld. Slechts €1M euro (Plus wat kleingeld voor de satelliet zelf te bouwen, maar dat fixen we toch gewoon zelf met reserveonderdelen in de space. Er ligt vast genoeg in de Stackspace!) | link | Adnub | |
| Netwerk upgrades: Ubiquiti EdgeRouter X SFP | €75,- (soms zo laag als €65,-)1 | Ons netwerk kan wel weer een beetje liefde gebruiken; deze router heeft out of the box belachelijk veel configuratiemogelijkheden en is geschikt voor klein- en thuiskantoor. de 5 Gbit poorten kunnen passive-power-over-ethernet schakelen en de SFP poort is ideaal om glas te verbinden. Met 1.4M packets/s (64 byte pakketten; 80kpps voor 1518 byte pakketten) is dit de ideale bang-for-buck router met migratiemogelijkheden naar 3.4Mpps/490kpps en 3.4Mpps/650kpps voor respectievelijk ~€210,- en ~€300,-. Al deze routers zijn geschikt om de LITE/MESH Unifi accesspoints te voeden. Zie ook de vergelijkingstabel | link | xopr | |
| Netwerk upgrades: 2x Ubiquiti UniFi AP-AC LITE (of combinatie met Ubiquiti UniFi AC Mesh | 2x€75,- (soms zo laag als 2x€65,-), Mesh: ~€90,- (soms zo laag als €79,-)1 | Bij een upgrade van de router hoort natuurlijk ook een upgrade van het draadloze netwerk; perfecte plaatsing van het wifi netwerk (niet zoals thuisrouters in de meterkast waar nooit iemand verblijft).
Deze schoteltjes bevatten 2x2 MIMO voor zowel 2.4 als 5GHz en met een actief draaiende controller ondersteunen ze ook mesh, load balancing en band steering. 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 | |
| Desoldeerstation - ZD-8915 | €106 | Maakt los wat vast zit. Headers verwijderen? Fluitje van een cent. | link | Adnub |

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'
Read it's status by subscribing to the sensor topics: mosquitto_sub -L mqtt://ackspace:ackspace@192.168.1.42/+/+/+/tele/SENSOR"
Install mosquitto-clients to start experimenting.
If you run into problems or find something interesting/broken, let xopr know.
topics
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 STAT RESULT POWER respectively).
At least ackspace, common, outside and services are supported as base. 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)
todo
- add MOAR sensors (upgrade the current temperature sensors)
- connect the space state to the MQTT server
- MOAR sonoffs
- define a better channel hierarchy

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 VIN 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.binon 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!
- either choose USB and put the firmware as
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)

synopsis
Vanaf heden (1-4-2020) is er elke:
- vóórlaatste zaterdag tussen 13:00 en 17:00 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!
