MOPED ARMY

I could design and make the boards for somthing like this, but wouldn't be able to handle the code. Man, board fab is so cheap now it doesn't even make sence to make them myself anymore.....what a world

Esp32 could handle it easily....I'm kinda blown away that this doesn't this exist already.

Man I haven't made any digital projects for such a long time, basically just been focusing on my ham, radio and tv resurrections......might have to think about this

I kinda joked a few years ago that I was going to make a tube based kinda--cdi with low voltage Soviet pico-tubes...because why wouldn't you use a tube instead of a 30 cent transistor or diode, then make a filament supply just because....lol that was such a stupid idea.

Using RTOS would make it work in real-time for sure

And this wouldn't make it any more complicated than a CDI box already is

You don't even need a full RTOS, you could run it from a simple interrupt trigger.

I have plenty o blasters that didn't require me to do any board level work. Like I said, if you're a computer man, this is sick. I just don't have the technical aptitude to make this, and can't see a reason to trudge through programming if I can plop a MVT/Malossi/Parmakit/HPI CDI no there and jam out.

Rtos? Then why not do real time logging of head and exhaust temperature as well an make a universal-ish two stroke tuning and datalogging device. This could go so deep.

Best option would be ability to change curves on the fly with a wired handlebar control, so I dunno. But....Wired control or just a phone mount.... economically speaking, server and phone mount are the way to go.

also, a phone would be ideal for actually modifying the curves too....

web repository to download different curves other have made?

Is anyone actually looking into doing this because it sounds fun. I really don't think an atmega is the way forward tho..

All this can be done with ESP32

2 core, up to like 200mhz processor, they have a few mb of flash usually, has WiFi and BLE and you can buy a devkit for 10 bucks

Like let's do it I have a bunch laying around

I would say that I don't have a testing setup at the moment, but I'll see if I can port this to ESP32 to start with

Yeah no this would def be open source, would be FreeRTOS if used as well

I ordered some esp32s and am pretty excited! It does indeed look like a great product for this. I've been out of microcontrollers for about a decade, and am amazed at how much these little guys can do.

My target project for this is based on a kinetic CDI, which triggers off of the inversion of the pulse rather than using an external trigger.

I have a basic RTOS shell code that stays online, so if you figure out the CDI code it should slot right in....

Ok fine I'll make a git repo for this today too

Additionally, my RTOS code will post data to an MQTT broker so if you run testing near WiFi you could do some live data streaming at ~1second resolution

There's some sample code I found for setting the wifi information via the Bluetooth, but right now I just hard code the WiFi info

For my use case (kinetic coils/flywheel on a vespa motor), detecting the zero crossing of the coil voltage seems like the important thing? I won't really be sure until I rebuild the engine I'm planning on using as the test bed.

I'm tempted to use a little comparator circuit for that, it'll be very fast and I can use the edge as an interrupt trigger.

yah I made it public now

will upload a bare bones RTOS skeleton later

Okay, I uploaded some example code that runs two tasks in FreeRTOS.

WiFi connection+MQTT and a memory check function

You'll need the hornbill AWS IoT library if you want to use MQTT, otherwise just comment that out
