My quest for a perfect hybrid vehicle
Browsing All Posts filed under »Motivation«
Hm, upgrades.
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 […]
Christmas time!!!
September 13, 2014
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…)
Got chips, will hack
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, […]
Teasing
August 14, 2014
Vnevoa: Hey buddy, how about you and me making one last sprint in July/August to finish the power bridges and get the Trike running for the Lisbon Maker Faire in September, just for kicks? I’m finishing my school work in a month, we could have a few hacking sessions like the good old days, what […]
My stand on Patents
July 4, 2012
(I wrote this 4 years ago, while I was planning to innovate a lot in the field of electric motor engineering. The innovations aren’t here yet, but otherwise everything is still absolutely true and the issue merits discussion.) Patents give you the right to stop everybody else from making, selling, or using something you created […]
