I got the nicely prepared kit for the power PCB from whereswally and a pimped brain PCB from lebowski. This brain is so tiny... almost the size of a post stamp. Now there's quite some work to do until it will be ready to be installed, here's my progress:
The tiny little poststamp-brain:
The soldering iron TS100 was recommended to me in the forum, it works much better than my other stuff:
Tried to add copper to the traces, followed lebowski's example. This took me many hours... at the beginning all was good, but the more copper on the traces, the more obvious it was that a more powerful soldering iron would be needed:
Then I tried to mount the current sensors and the FET with the cut-off leg. The same problem: Not enough heat, skills, helping hands etc., the things are more glued than soldered:
That's it for the moment, something between euphoria and frustration. The power limit is probably not defined by the design and the components, but more on my soldering skills...
By the way: whereswally included 22 ohm 'ON' resistors instead of the 15 ohm lebowski has found to be ideal. Would it be pedantic to buy 15 ohm (1/4 watts?) or can I leave them at 22 ohms?
And lastly: I admire minimum's perfect heat sink. Without proper workshop, this will be another hurdle for me... but all in all: Happy!
Modified Scott Nitrous, 74V, MagicPieV2, waiting for Lebowski-Controller by whereswally
Quantya Evo1 and eScooter vRone, each with Lynch motor, 74V 40Ah, Alltrax AXE 7245
Dream: Quantya with Lebowski-Controller and brushless motor (Revolt RV-160, Colossus, Emrax 207, ...)
