So I've done some soldering and some wiring work on cars in the past
mostly related to solving electrical gremlins.
When I was young I was into electrical stuff and assembled few kits,
that never got me anywhere. Probably because they didn't have a purpose.
I was looking for a sequential shiftlight and wasn't going to pay Motec/etc.
for bunch of LEDs, Stumbled upon Chippernut and it was the thing I was looking for!
Ordered the parts from a sketchy Chinese online store and had to wait like 3 weeks,
I alreaydy done some research on the schematics and visited my local eletronics store,
mainly to pick up the resistors, transistors, kynar and a protoboard along with some connectors.
I made a few prototypes and tried to squeeze everything into the board as tightly as possible,
still keeping it pretty straight forward.
Got the parts and soldered them into the board, FAIL! gotten used to soldering transistors at this point
I mixed the ''legs'', had a miserable time pulling them and replacing everything on RPM/Dimmer circuit.
Well after everything was together, did some measuring and everything looked OK this time.
After that came the scary part, writing the EEPROM, Never done any coding etc.
The instructions where up to the task and made things very easy!
Damn! no display? played around with the rotary ''blind'' and saw that the LEDs worked
as they should, brightness, number of LEDs, colours and segmentation worked fine.
Soldered every joint on the display including TM1637 chip but no go.
Now I'm waiting replacement for the display and the LEDs that where not what I ordered :/
Probably takes ages.
Going to install this to my -92 BMW 325i, gonna make a great addition to the ''race like interior''
hopefully the RPM signal won't cause me headache, if it doesn't work? I'm not worried
Got a Maxxecu awaiting on the shelf so with that I'll be able to get the signal
if my initial plan fails.
-Make one more mode for the lights '' from sides towards the center''
-When hitting the shift point, lights turn desired colour ''static''
-set limiter point, When hitting the limiter lights flash as they now do on shift point.
-Adding some additional info on the dimmer? Do you need to connect it? What to?
How does it work? And can you delete it from the circuit if your not planning to use it?
-The rotary seems a bit weird but that's probably due to lack of my display :/ it needs to be more responsive when turning fast and slwoer/precise when turning slow
Ps. Thank you for this wonderful thing, it has made me very happy and interested in coding/electronics again!
