About me

I'm Wim, from the Netherlands. I work on electronics and hardware projects in my spare time. Sometimes for fun, sometimes because I convinced myself it couldn't possibly be that hard.

Occasionally a project turns out well enough to sell. You'll find those in the shop.

View fullsize Progress! Recently started working on the main wiring harness for the car. This will connect all the new modules in the car for the powertrain. The routing was done in advance by tying pieces of string together between the modules in the car. And th

View fullsize Decided to use the dilithium bms from thunderstruck ev instead because this is the fastest solution right now. This meant I had to solder wires directly to the existing bms as the cell connections on the battery pack are aluminium. This was quite tri
View fullsize Finally ticked this one off the list✅ The floor and tunnel are back in. This took quite some time, since obviously nothing fitted and I had to modify a bit more than expected. But the result is what matters. #metalfabrication #chassisfab #cutting #w
View fullsize After many hours of struggling, the motor is finally mounted in the car. Unfortunately I had to cut away from the rear seat more than expected, but don't worry. This will be fixed with a few rigid 3d sheetmetal parts. #electricconversion #electricca
