PWM controlled Brake light controller [Open Source]

Sure, it’s the better and more flexible option…

No worries at all! Ive actually refered a few people to your thread on the builders forum cause they were looking for a controller like this Great to see you posting updates to this project. I was worried you got too busy for it. There is definitely a need for this and its always great to have more options out there

i would be happy with an always on light that gets brighter when i brake

Any updates on this? I’d pay someone to build me one

So these are not sold by you in any stage whatsoever? One would need to take the design you have openly shared, source the small parts, assemble… etc?

# Introduction:
This is the firmware for my open source pwm controlled brake module. It's designed with esk8 in mind but can be widely adapted.
Is has an 5V 3A onboard buck converter and an Atmega328p to controll it all. 
The schematic can be found here:  https://easyeda.com/mich21050/light_controll_smd
It's pretty simple to set up so here we go:

# Setup
1) Download the latest firmware from the release tab: 
2) Unzip the downloaded archive. Install Arduino IDE and the FASTLED Library (if you don't know how to just do a quick little google search). Now run the "hardware_bat" file.
3) Connect your USB-Uart board with your controller. Now select the "ATmega328 on a breadboard" under "Tools">"Boards". Now upload the PWM_Readout.ino script . Now open up the serial monitor using a baudrate of 11520.

4) Disable autoscroll and hit the brake on your remote control. Now note down the lowest value your are given (there might be a bunch). Now subtract 10-15 from your given number.
5) Now you open up the light_control file and open the config.h file.  Now replace the generic value that is next to "threshold" (the line is marked) with your own number.

5) Replace the number next to "num_front" with your led count on the front led strip. Now do the same for the "num_back" value. For example: I'm using @mmaner's led mount so 8 leds in the front and 8 leds in the back. So my "num_back" and "num_front" value would be 8.

6) Hit upload and you are good to go.

So currently no, I currently don’t sell any controllers but I’m planning on doing so in the future once the new revision is working(with a mpu-6050 for more compatibility and external load switching). The current one is pretty easy to solder so you should be able to solder it pretty easily.

once the new version is available, I’d be happy to assemble a batch stateside

At 8$… I might just have to try. Those pads look pretty small in some places… you need anything special?
Also, if the pcb isn’t sold, I’m assuming you have to have it custom made by one of those online Chinese board producers, right? Research time.
Anyway, thanks for the all the work you have put into this!

Mich21050 · March 11, 2020, 2:24pm

No problem. If you can wait for around 1-2 more months I’m going to sell a bunch of the new better and function richer board… just saying.

Nope not really, Just a steady hand and a good soldering iron.

Yep. jlcpcb.com

Anythin poppin over here yet?

sleepless · January 24, 2021, 10:40pm

Would love to have a reactive brake light controller module. Is this project still ongoing?

Fosterqc · January 24, 2021, 10:52pm

TTL and the freesk8 lightshow modules are ongoing.

There are the acceleration reacting ones for bikes too.

sleepless · January 24, 2021, 10:58pm

Yes, poor man’s option is something like the xlite100 or Nkomax with built in accelerometer. That’s not a bad solution, I just like everything wired to a single battery pack, utilizing the data already provided by the VESC.

I need to keep researching how complicated it would be to utilize a buck converter + ESP32 / NodeMCU / Arduino. It’d be nice to have a little microcontroller on board for future projects.
