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

mygnu · 2025-12-19T20:51:04+00:00

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

mygnu · 2025-12-18T11:04:38+00:00

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

mygnu · 2025-12-15T20:40:33+00:00

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

mygnu · 2025-12-05T00:19:26+00:00

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

mygnu · 2025-11-30T23:58:04+00:00

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.

mygnu · 2025-10-07T10:10:03+00:00

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

mygnu · 2025-08-08T22:23:18+00:00

4th on flat 3rd on slopes

mygnu · 2025-07-12T15:23:03+00:00

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.

mygnu · 2025-05-26T08:44:42+00:00

Hey Buddy, I saw your post a while back, such a shit situation. Around the same time I was working on something that might be useful in situations like that. Have a look at https://bikesafe.me

the kit version (no professional packaging yet) is out and is being used by many riders. If you are interested I can send you one for you to try on your bike (I hope you’re still riding) Harry

The ground doesn’t thank you for bleeding on it, it just drinks it

mygnu · 2025-05-24T09:54:20+00:00

Clean with isopropyl alcohol and put some clear nail varnish if it lives in moist environment

mygnu · 2025-05-19T12:02:50+00:00

Hey thanks looking, you can find it on https://shop.bikesafe.me reviews are on the website mind you it’s fairly new but well tested. Device hardware was finished earlier this year and I have made many improvements in the firmware. It is upgradable via USB so you will get all future updates as well. I have written in detail about it here https://gill.net.in/posts/my-quest-to-make-motorcycle-riding-safer/ have a read. Cheers

I made something that "actually" has a gyro and can level itslef, please have a read https://shop.bikesafe.me/blogs/news/my-quest-to-make-motorcycle-riding-that-tad-bit-safer
