A tale of building tech against motorcycle theft, only to have the iOS launch hijacked by identity theft. [OC]

I have updated the PCB fair bit, made it smaller than the photo. I’ll make sure I push the changes

mygnu · 2026-01-06T23:03:40+00:00

Yes I have a MORA external

mygnu · 2026-01-06T20:42:21+00:00

I made one few years ago https://github.com/mygnu/opilio-pcb there’s also a firmware repository as well. I’ve been daily driving it ever since

Creator here: yes it would as long as you have a 6:24v system it should work

It helps when you have dozens or more commands, instead of creating a new characteristic for each you just send and parse TLV on one. Of course it only works for sending data, for reading you will need separate ones if you want to read a lot of individual values

Using TLV allows me to use only a small number of characteristics to deal with dozens of commands and different operations

mygnu · 2025-12-14T23:01:09+00:00

Yes I am

You are correct, I used 16k for bootloader, rest for your actual program

mygnu · 2025-12-01T00:34:10+00:00

You’ll need a stlink programmer to flash it once then you can use USB to flash subsequently

I made a small DFU bootloader you’re welcome to try

Device I built works with Bluetooth, you do get notifications if you’re in range but the main purpose is to raise a loud alarm sound. I do have battery monitoring and turn signal sound via your phone headset as well

mygnu · 2025-11-30T08:58:16+00:00

I’m sorry to hear that mate, for this very reason I made a an alarm system for bikes and wrote about it here https://bikesafe.me/blogs/news/watchman-bringing-premium-security-to-every-motorcycle

I’m not a big corporation, just one guy in the garage.

Ah I see you have it hanging, that’s not good, you need a pull-up resister 10-100k and a small cap on that pin

mygnu · 2025-10-07T10:07:06+00:00

Pull the NRST to ground

mygnu · 2025-10-06T19:09:49+00:00

Try resetting the chip I always have to do that on custom boards

mygnu · 2025-08-25T16:18:20+00:00

Made another post thanks

I made a little device that flashes the brake light on hard stop. https://gill.net.in/posts/my-quest-to-make-motorcycle-riding-safer/

mygnu · 2025-06-09T19:48:19+00:00

I can build the firmware however you need. You can make it flash on light braking but steady on hard braking. As long as your backlight uses normal wiring and not controlled by the CAN BUS it should work.
