Controlling the Instrument Cluster's Display

A little project I'm working on. :) (Sorry for the horrid picture!)

Here's the elevator pitch: Directly control the LCD panel with a microcontroller to display custom information on the instrument cluster. The microcontroller will also read the data that would normally be going to the LCD and can choose to display that info or custom info.

Maybe you want to display OBDII parameters where the MPG is. Maybe you want to change the charge, assist, and SOC gauges to accurately reflect amps in/out, real battery SOC, etc.

I've got a few other ideas as well. Once I'm finished with this project I'll open-source everything I've learned and perhaps produce some PCBs to sell. We'll see!

I have work and other projects as well, so it may be slow going at times. But I'll try to give updates fairly regularly.
I don't think this has ever been done before. I hope you guys are excited!
If anybody is or wants to work on something similar, I'll be glad to share what I know; just ask.

I'm undoubtedly going to need one of these soon. So there's a sale from me as well waiting in the wings.
That is amazing.

There are two unused light sockets in the cluster. One of them is next to the IMA light and the other is in the same area, but on the opposite side of the cluster. By any chance are you able to address (or control) those?

I've thought about using use one of them for to indicate lean burn and the other to indicate when cruise control is in use. Would also have to have new gauge faces made for those spots as well, but that's would be the easy part.
I really enjoy reading updates like these. I guess I must have a similar affliction.

Looking forward to the day I can hopefully install at least one of these in my 2005 or my 2006 Insight.
Doesn't scare me.

Does the pegasus design you are currently working on, fit late model Insight clusters?
For hand pick and place, I can reliably place and successfully reflow 0603 components. If I have to, I can also do 0402 components.

I've also recently had good success with 0.65 mm pitch DFN/QFNs.

I avoid 0.50 mm pitch components as those have given me issues in the past.

This is using leaded solder paste. Lead free solder is stuff of nightmares for what I do.
