TIme for an overhaul
The mini shell being away for restoration for such a long time, fast approaching a year as I type, gave me the perfect opportunity to revisit some of my earlier work. It was time for an overhaul.
I am including everything here so you can create your own version of my speedometer. During my research I would often find examples of what I was trying to achieve that were lacking in detail or incomplete. I hope this resource proves useful to someone and saves you some time.
Everything offered here is to be used at your own risk. I do not accept responsibility for any mistakes I might have made that cause you to make the same mistakes.
If there is enough interest I would consider supplying the circuit boards and components in kits so you can create your own. Get in contact if interested.
