Random Site Update Season: Almost All the Things

chorl

More parts of the site have been brought to modern documentation standards!

First off, the scooter hub motors finally have their own summary page. Now go build one – seriously, there’s more than enough pictures on this site of all of them. Build a Kitmotter at least!

The motor controllers page has been updated to include tinytroller and Segfault’s motor drivers, along with Melontroller 2.

Among the vehicles to get their own pages are melonscooter (finally too!) and Straight RazEr. The EV page has also been updated with more recent pictures.

What I haven’t gotten to yet are the fail-at-flying things, namely Chuckranoplan and the *copters. Maybe when I actually get one of them working…

Tinytroller: More Tinytrolling

Tinytroller sucks. It’s terrible and I wish I never designed it. Who the hell tries to make an Arduino powered brushless motor controller anyway?

Okay, so it isn’t quite that bad. I took today to finish knocking out some basic square wave commutation code in the manner of Melontroller (which, by the way, is finally on my Motor Controllers page). As with any new design, there are some issues both small and large. The board has been found to be quite noisy – at higher motor speeds, the Arduino tends to crash and reset. There is also a minor, possibly software-induced issue with running at low speeds which appears to cause current draw spikes (also causing the board to crash).

The first assembled Tinytroller board has been beaten to hell and back to observe the symptoms of the problems, so it might be worth my while to just make a new assembly to test from. Here’s the recap of the limited, and slightly disappointing, testing from today.
