I’m converting an older road bike to e-assist. I want to keep the aesthetic of the older bike intact. This means keeping the Campagnolo Record 10 speed groupset currently on the bike. One thing to consider is how I’m going to control the motor. I want to keep the feel of a road bike, so I don’t want a thumb throttle. I also don’t want a cadence sensor governing power to the motor. So my only option is to install a torque-sensing bottom bracket. All of the torque-sensing bottom brackets on the market are made to JIS square taper standards. Campagnolo uses the ISO standard. Here’s what I learned about the interchangeability of these standards.

My Saved JUMP Bike
Since initially writing this Lime has started to reintroduce masked JUMP bikes into the Atlanta area.
I recently built up a reclaimed JUMP e-assist bike. These bikes were everywhere in Atlanta. I rented them pretty regularly myself. Eventually JUMP pulled out of Atlanta and these bikes disappeared. Several months afterwards though, I started to notice a few JUMP bikes sitting in abandoned lots and ditches. They had all been picked over. One was missing a front wheel, another a battery. A third bike was mostly frame and rear wheel. I quickly realized that between the three bikes there were enough parts to cobble together a complete bike. This got me down a rabbit hole learning more about these bikes. I had to scrape through lots of bits of information around the web. I also learned a lot about these bikes during the teardown.
R.I.P. Device Farm
I’ve been an Android developer at three different companies in my career. At each company I tried to set up a device farm and run instrumentation tests on that farm. After three attempts, I’m finally giving up.
Home Built Kegerator
One of the last side projects I worked on before leaving Big Nerd Ranch was to build a kegerator for the office. We wanted to have beer and nitro iced coffee on draft. We didn’t want to buy a setup for carbon dioxide and nitrogen so we built one.
Ultimate Geek Desk
My desk at work has slowly evolved into a paired-down essentialist work space. It started with a height-adjustable GeekDesk v3. I added a Ergotron desk mount for my external monitor. I also added a Rain Design mStand for my Macbook and several egalo M2 stands for my Android devices. With a set of bluetooth mouse/track pad my desk was complete. However I wanted to use our company 3D printer to make a few small parts to make my work experience even more streamlined.
