What am I doing...?: AND NOW BACK TO OUR REGULARLY SCHEDULED PROGRAMMING
http://hellobowtie.blogspot.com/2017/01/and-now-back-to-our-regularly-scheduled.html
Monday, January 9, 2017. AND NOW BACK TO OUR REGULARLY SCHEDULED PROGRAMMING. An autopsy of the YASA was performed in lieu of its failure at competition. On site, the controller was throwing encoder faults, the reason for which became incredibly apparent once we'd disassembled the drivetrain. Motor Exposed to the Elements. The JST style connectors are for thermistor breakouts that are fed through the main "DATA" connector. Further, the board appears to have a conformal coating, presumably for HV isol...

What am I doing...?: WELCOME TO CAR TEAM, HOME OF THE CAR TEAM
http://hellobowtie.blogspot.com/2015/12/welcome-to-car-team-home-of-car-team.html
Tuesday, December 29, 2015. WELCOME TO CAR TEAM, HOME OF THE CAR TEAM. Semester is finally over! Of course, this only means that the time previously dedicated to schoolwork is now consumed by cycling and CAR. This week I've been getting the boards in line to be sent out to Advanced Circuits. Namely, the GLV motherboard, as well as the board for the steering wheel and HV panel. A board for the steering wheel? A thing of dreams @ @. Subscribe to: Post Comments (Atom).

Sunday, February 9, 2014. Pseudo-Solder Paste, Shiny Knobs, and Jason Whisperers. Roughly three quarters of the time it takes for a project to be completed falls into at least one of the following categories:. A) waiting for things to get shipped. B) waiting for funds to appear to buy materials. Anyway, all this waiting is what led me to delve slightly deeper into the world of hand-etched pcbs. Most notably, that thing where you tin your boards. The fire nation attacked. I discovered this page. For givin...

Saturday, July 5, 2014. A Midsummer Night's Blog Post. WHERE DID ALL THE TIME GO! LOOK AT THESE IGBTs! Current limited by the package leads,. Among other things, these are the perfect candidate for some pulsed, hard-switched, power dense goodness. And so the journey to building a QCW bus modulator begins. In essence, the modulator portion of your QCW coil is just a buck converter capable of producing arbitrary waveforms across the bus of your DRSSTC. Special notes: the input signal is actually taken from...

What am I doing...?: BATTERY PUCKS, BUCK CONVERTERS
http://hellobowtie.blogspot.com/2015/08/battery-pucks-buck-converters.html
Saturday, August 29, 2015. BATTERY PUCKS, BUCK CONVERTERS. With but a few weeks left in summer, I decided that it was a good idea to start designing a sort of universal battery pack for silly EVs. The goals of the project are to incorporate the following features:. Hot-swappability"/fancy latching holder mechanism. Taking a cue from modern cylindrical cell based EV packs, I started with a modular frame structure. A few test prints later, this appeared:. Buck, buck, buck, boost. One of the reservations I ...

Monday, December 16, 2013. One Bit ADC and a (Not) Wheelbarrow Shaped Object. With the semester winding down, and final project(s) nearing completion, the coil was revamped and the project part of my final project was made. The goal was to have a working analog interrupter which would take an analog signal, such as the one coming out of an mp3 player, and then be able to play it through a Tesla coil. The block diagram is the following:. Signal - Amplification - Triggering - Poopy sparks. Rate for 96A at ...

Sunday, November 17, 2013. EPIC OCTOBER-NOVEMBER PROJECT DUMP. I really ought to start documenting projects as I go along. Broken down into three parts, yo. Once on my bucket list, this blue laser pointer was what constituted an overnight build-a-thon at MITERS. In my laser-induced, sleep-deprived stupor, I forgot to document much of the build, although, there wasn't much to do to begin with. Diode: 445nm rated for 200mW. Power: two lithium cells (7.2V nominal). Driver: ebay diode driver. I assembled a d...

Caffeine, most of bluescooter (yes, it has a name now), was done in the lead up to Maker Faire New York. Sadly, it wasn't completed in time for the faire due to a lack of functional waterjets, but the progress so far deserves a post of its own. But, as with the best laid plans of mice and men, it required some love on the lathe. Something's telling me that I should've used a smaller chuck. Those...
