Hm, upgrades.

October 22, 2014


One of the problems we’ve been having from the start is that the motors I used were recycled from a couple of electric scooters and not only they are kind of weak, they are also unequal: one is 200W nominal and the other 240W. This wasn’t too apparent until recently when we implemented regenerative braking, […]

Off to the Faire!

September 22, 2014


NOTE: THE Lisbon Mini Maker Faire 2014 IS NOW OVER. THIS IS A POST-POST. 🙂 The Trike is finally ready for show time. Please have a seat and take a smooth ride… So I packed it up on my car and went off to the Maker Faire. Once we got there, a lot of people […]

NJay: Look what I brought you… Vnevoa: YESS!! 🙂 My turn to play with them!! 😀 And as soon as I got home I tried them out for size on the chassis… (to be continued…)

September 5, 2014


NJay: Yo, my miniCNC project was accepted as well!! 🙂 We’re gonna have 2 tables at the Faire, I’ll ask them to put us together. Vnevoa: Cool! And they also approved H0tR0d’s e-bike! 🙂 We’re gonna have a cool time with all the gadgets. NJay:  By the way, they’ve published your project. Vnevoa: Wow, they’ve […]

We’re really going to the Faire! :)

September 4, 2014


Vnevoa: I’ve finished building the new heat sinks for the second power bridge. Here’s how it looks with just one of them: NJay: Cool, I’ll take them home now. Meanwhile the I²C chips arrived. My friend has them, I have to go get them from him. Vnevoa: Finally, we’ll be able to get something done […]

First Add-On board schematics, speed sensing, Faire

August 19, 2014


Njay: Ok, new revision with LEDs for the I²C on both sides of the insulator, with a port for the motor temp sensor and a second sensor for the bridge temp (there’s 2 heat sinks per bridge). At the moment not providing for the external speed sensor. Using a Hall or other type where we have […]

Bus insulation & Speed sensing

August 18, 2014


Njay: + Motor Temp: Right. + Motor Speed: I don’t know what to do with that. It all depends on the kind of sensor we’ll be using. + Don’t we need another on the RasPi? Nope. RasPi drives the bus and the insulation happens near the slave bridges. If we insulate near the RasPi too, […]
