Hey all! You might have seen some things about this project before, but I would love to highlight it here as well! Ive been working on this project for the past year, and Ive finally settled on a software and hardware package that can rival some of the more expensive Artnet controllers. With a hardware revision that now supports resettable fuses, variable input voltage, hot-swappable plugs, and reverse polarity protection, I am more than confident that the node will appeal to LED-strip enthusiasts out there! For the non-professional, tinkerer, DIY geek or Christmas nerd, this node is a game-changer!

So, in short, what does it do?
- 16 universes over 4 outputs, so 2700+ RGB LEDs in total!
- Support for WS2812 type (800khz) and SPI driven leds (SK9822, apa102), so basically any LED-type on the market!
- RGB, RGBW, and RGBAW colour arrangement support
- Ethernet and wifi capable
- Integrated power distribution up to 5A per output and 20A total
- With a 5~24v variable input, this means almost 500W of power!
- OLED display for status updates
- Hardware button to change between different modes (DHCP, Static IP, Static colour, Test pattern)
- But, most importantly, completely open source! Every piece of the software and hardware design is available for you to tinker with!

Now, let me know if you have any questions about this project! Before I see comments about WLED: Yes, WLED does Artnet and SACN, but performance is worse at a maximum of ~9 universes, and IMO WLED setup is a lot more complicated. This node is straight to the point and ready to use with Artnet out of the box!

Also, no, sadly, the node does not support SACN. I know, I will try to get this to the node in a future update!

Now, if you are excited, check out the GitHub! https://github.com/mdethmers/ESP32-Artnet-Node-receiver/tree/main

edit; sACN should be very easy to add to the controller. ill investigate if this can be something on the short term!

Hey! I know promotions like this are not necessarily permitted, but I hope this can be for the greater good of us European electric go-karters. 

Hey all! I have been struggling to find pre-fabricated(!)motor mounts for various Surron, QS165 and QS138 motors here in the EU. There are many that sell mounts in the US, but shipping and importing to the EU is too much for a bunch of steel. Additionally, I think most of these mounts go way too high in their price, sometimes reaching up to 200$ for a simple mount.

Therefore, I have decided to sell affordable and DIY mounts for the QS165 35H 50H (Surron motor compatible) and the QS138 70H 90H! Made of 4mm steel these mounts are made to withstand ~20KW of power!

I sell these in 2 versions;

• Affordable DIY kits > Weld the 3 parts yourself! Shipping only ~€10 through > Price €75 (Both QS165 and QS138
• Pre-welded > I weld it for you! Don't expect premium welds, but it will hold up just fine!

I'm also available for custom enquiries. Let me know if you have any questions!

Hey all! I would love to hear your feedback about this PCB i designed, which uses an ESP32 and W5500 module to receive Ethernet and control LEDs over Artnet. I copied some of the power management and level shifting capabilities from the Adafruit sparkle PCB, but as I picked different parts for some of the design, I would like some eyes on the following points.

- 5/24v-to-3v Buck converter. I copied the design from the Sparkle, but as I am unfamiliar with buck converters, I am not sure if this will work. I only need 3V for the ESP32 and W5500. The Buck IC is rated for 2A, and the inductor is rated for 2.6A, 8.2uH, and 45miliOhm, saturated at 3.2. Would this generate a workable 3.3v rail?

- 5/24v-to-5v converter. Should supply 300mAh, which should be enough for the level shifter (works from 4.5v and up), OLED screen, and WS2812.

- The level shifter outputs a clock signal to the output. This router over the power plane, and Im worried about noise reaching the SPI or signal lines. I cannot think of another way to have my Clock and Signal reach the connector though.

- Any other recommendations, feedback, or suggestions are appreciated, as this is my first integrated circuit on a PCB. Thanks!
