I found keeping track of my location in thousandths of an inch hard to remember and messed up on the last letter. I learned a bit about small size tooling and some of the CNC "do one" functions on the Proto-Trak systems mill.
At the left is a bracket for my friend Joseph's new electric long board project.
Below is a picture of my most recent practice on the lathe making a 'door handle' for my friend Jane.
This year, I built IoTaser. It's basically operating a potted, high voltage inverter using a Particle Photon board. The phone app native to the Photon allows me to send pins high/low on the controller which operates a series of MOSFETS in the device to charge a boost converter.
Unfortunately, the new charging wires I put into parallel with the battery output slightly bulge the enclosure outwards. This is something I can understand though and fix later.
Also, terminal strip connectors exposed to high current jumps (think water hammer) can only go through ~20 or so cycles (during recharging) before they lose serious efficiency and start heating up locally.
|A friend of mine is interested in adding hall effect sensors to a motor, something like this I think.|
Contrary to what seems like the higher truth (fuzzy logic reference). This post is not about bikes. I like bikes but I also like another kind of pedal. The effect pedal. An effect pedal has two inputs, power and audio-in. The output is audio-out.
|This is the schematic I based my design off. I used large voltage biased capacitors and larger pots (greater range).|
