{{#Widget:Html5media|url={{filepath:sleevePoE.webm}}}} Artistic impression on how the (new) sleeve works. == synopsis == LED sleeve, also known as OHM2013 torch is a project [[User:Xopr|xopr]] wanted to do a long time, so at one blue Monday in the summer of 2020, he decided to just build one (two actually), a [[Micro sleeve]] in May 2024 and a PoE Sleeve++ in September 2024. I didn't want to take the trouble to order descent PCBs so everything is piggybacked and hotwired. == first version == [[Image:LEDsleeve.gif]] I piggybacked an ENC28J60 module to an Arduino pro mini (that's all there is to, actually). === build === The list you need to build one: * 1 Ledstrip WS2812 5m30L/m * 1 Arduino pro mini (5V) * 1 ENC28J60 or ENC28J60 mini with a separate LM1117 regulator * 1 power supply 5V8A (laptop PSU form factor) * 1 prototype PCB 13x16 or 8x20 holes (wide v.s. narrow/mini) * 3x2 screw terminals * 1 header 2x6/2x5 (for ENC28J60 regular v.s. mini) * 33cm rainwater drainage (HWA or "hemelwaterafvoer") tube 70mm * 1 lid 70mm * 4 wire crimp terminal 1.5mm (recommended) * 1 or 2 wire crimp terminal 0.5mm or 0.75mm (recommended) * 0.4m cable 2x0.75mm * 1 wooden base ~70mm diameter * 2 large zip ties (to fix the LED strip) * 3 or 4 wood screws (for the base) * 1 network cable * 1 power cable * 10cm shrink wrap (recommended) * 2/12th paired screw terminals (recommended) * 1/4th thick broom stick with a large screw (optional) * either ** flag pole holder (optional) ** or [https://www.gamma.nl/assortiment/grondplug-grondanker-vuurverzinkt-63x550-mm/p/B032738 ground screw] with 2m tube (optional; [[User:Xopr|xopr]] used 3 reduced/verjongde 64cm tube coming off a trampoline) The PCB is just a connector between ENC28J60 and Arduino (AVR) <gallery> Image:LEDsleevePCBTop.jpg|PCB Image:LEDsleevePCBBottom.jpg|PCB solder side Image:LEDsleevePCBBottomOccupied.jpg|PCB solder side occupied with ENC28J60 Image:LEDsleeveDiagramNarrow.png|Diagram for ENC28J60 mini (3.3v) Image:LEDsleeveDiagramWide.png||Diagram for 5V ENC28J60 Image:LEDsleeveTop.jpg||Top with lid removed and screw terminal visible Image:LEDsleeveBottom.jpg|Bottom with backfeed for screw terminal visible Image:LEDsleevesComplete.jpg|Completed LED sleeves </gallery> === notes === The cost per led sleeve is between €35,- and €85,- depending on your sources (local/ebay/scrap). Some important notes: * the correct winding is top to bottom, clockwise (seen from the top, i.e.: from top right to bottom left) * I had old Arduino pro minis with old/wrong bootloaders: for these kinds, select Arduino Uno to be able to upload any sketch * make sure you don't use other diameter pipes (like 75mm drain pipes) or your image will be garbled * to solder the headers on the solder side, you have to offset them from the PCB (I used scrap plastic from zip ties) * the power supplies on ebay are '''very dubious!''' They are refurbished (sloppy) and given the wire gauge I strongly doubt the were built for 8A continuous use. Don't leave them unattended * feed the ledstrip from both sides to prevent discoloration * the Arduino libraries can be a pain to find and/or get working. YMMV. * for added safety, crimp your stranded wires; it's not worth risking fire for a couple of cents extra * regarding the firmware<ref>[https://github.com/bobo1on1/loc_controller controller firmware]</ref>, make sure to install these specific library versions (and no higher as these are the last working versions for this project): ** EtherCard 1.0.0<ref>https://github.com/njh/EtherCard/releases/tag/1.0.0</ref> ** FastLED 3.3.2<ref>https://github.com/FastLED/FastLED/releases/tag/3.3.2</ref><ref>https://fastled.io/</ref> == sleeve++ == This version uses a PoE++ injector and a PoE+ splitter to have less cable clutter and make life easier. It also switches from a cheap Arduino pro mini, ethernet and perf board "glue" to an Arduino Nano clone; the LGT8F328P-LQFP32 MiniEVB, and an ethernet board that fits this footprint. The LEDstrip is 12V this time and the AVR clone came with its own challenges, but nothing major. === notes === * The Ethercard library had to be modified to use the Arduino SPI methods (so SPI initialization is done correctly on the LGT8Fx) * I fried an ethernet controller by putting 12V on the Arduino Vin pin; the Arduino itself was able to handle it, although it became very hot, so I switched to a buck converter to be on the safe side. * All LEDS on will draw approximately 1.688A (at 12V) * Originally, I had a PoE++ 7.5A extractor, but it doesn't fit in the 70mm tube; I was thinking on buying an adaptor but I tried small extractors first: ** LS-POE-1210GK: jumped into protection at 1A ** LS-POE-1210E, the 24-48V version also jumped into protection at 1A ** LS-POE-1210DK: success using approximately 1.5A, but seemed to have some glitches === todo === * share ethercard changes * moar pictures == also see == <references /> ** [https://bitlair.nl/Projects/Ohm_led_strip_sleeves Ohm led strip sleeves on Bitlair] ** [https://wiki.tkkrlab.nl/tkkrlab.nl/wiki/OHM_LEDS.html on TkkrLab] ** [https://eventinfra.org/ EventInfra (they loan these sleeves and have 90+ of them)] ** [https://github.com/AlbertVos/bitlair-ohm2013-ledstrip-contol bitlair-ohm2013-ledstrip-contol] ** [https://bitlair.nl/Projects/ledcat new ledcat control software] and its [https://github.com/polyfloyd/ledcat github page] ** [[Micro sleeve]]
