I2C and Device Limits
SparkFun’s Peter Dokter has an interesting video talking about SPI and i2c comms. i2c in particular is a great bus mechanism, due to the microprocessor only needing TWO wires to control (almost) any...

Eagle: Text Silkscreen Width
Thanks to Hackvana, I’m making teeny tiny circuit boards! No matter how good a board house’s process, there are some fundamental limits to how small things a board and the design on it can be. A PCB is...

Springless Reversible Mechanical Logic
Logic gates! The building blocks of computing as we know it. What if we ditch the electrons? I want some mechanical logic for an upcoming project, so I did some research… Research There are several...

Logic Gate Linkage Calculations
In my previous post, I simulated some mechanical logic gates using a novel 3-bar linkage. The dimensions of the linkage are critical to achieving correct operation; Inputs \(\{ false\ false \}\), \(\{...

All the Switches
I recently bought a heap of these switches – small DPDT toggle buttons – for $0.07 ea. Quantity over QualityThese switches are not that large, the on vs off height difference is only about a...
