A place to share practical, durable and quality made products that are made to last, with an emphasis on upcycled and sustainable products!


Things that are well-made and durable (even if they won't last a lifetime) are A-Okay!

Unlike that other BIFL place, Home-made and DIY items are encouraged here, as long as some form of instruction is included in the body of the post.

Videos links are not allowed as post titles, but you may use them in a text post.

A limited amount of self-promotion is accepted, IF the item you are selling aligns with this criteria:

  1. The item must be made with sustainable or recycled materials.
  2. If electronic in some way, the item must be open-source.
  3. The item must be user-serviceable (if applicable).
  4. You cannot be a large corporation.
  5. The post must be clearly marked with a [Self Promotion] tag in your title.

If the motor mount is hackable with reasonable effort, and the motor controller's interfaces are open, then in principle... yes.

Yet in reality, companies build extremely complicated cars where premature failure of multiple components can successfully sabotage the whole. :(

I've once needed to repair a Mitsubishi EV motor controller. It took 2 days to dismantle. Schematics were far beyond my skill of reading electronics, and I build model planes as an everyday hobby, so I've seen electronics. Replacement of the high voltage comparator was impossible as nobody was selling it separately. The repair shop wanted to replace the entire motor controller (5000 €). Some guy from Sweden had figured out a fix: a 50 cent resistor. But installing it and putting things back was not fun at all. It wasn't designed to be repaired.

Needless to say, replacing a headlight bulb on the same car requires removing the front plastic cover, starting from the wheel wells, undoing six bolts, taking out the front lantern, and then you can replace the bulb. I curse them. :P

But it drives. Hopefully long enough so I can get my own car built from scratch.
