Ever want to control some outdoor lighting without using your phone or going back in the house? Read on to see how I installed a set of landscape lights then built a set of outdoor, waterproof Zigbee buttons to control … Continue reading →

Two years ago, I hung a set of generic G50 RGB globe lights in the backyard. They weren’t exactly waterproof and the individual lights became water logged and started acting erratically. This year, I replaced them with two sets of … Continue reading →

In my my last post, I looked at four different sets of inexpensive LED flood lights to see which could be controlled using WLED. While they all could be controlled with WLED to some extent, only some could take advantage … Continue reading →

I’m always looking for new LED lights for Halloween, Christmas, and just general tinkering. My preference is for lights that can be modified to be controlled locally by WLED. Controlling the lights locally lets me integrate the lights into larger … Continue reading →

A video of my hardware and software controlling the pointer and counter on a 747 fuel quantity indicator. In this post, I disassemble a 747 fuel quantity indicator and reverse engineer the electromechanical parts of the indicator. I then apply … Continue reading →

A video demonstrating the play back of a descent from a recent mountain bike ride on the vintage aircraft altitude indicator.. In this project, I use a Python script and an updated version of my digital-to-synchro project to replay my … Continue reading →

A video showing the Kollsman electric tachometer indicator ramping from 0% to 100% then 105%, 120%, back down to 100% then to 50%, 25%, and 5% then finally back down to 0%. At 100%, the three-phase, four-pole AC synchronous motor … Continue reading →

In the last project, I built a synchro-to-digital converter to display a synchro’s shaft angle on a small OLED display. In this project, I reverse the process and build a digital-to-synchro converter that sets a synchro’s shaft to the angle … Continue reading →

This project uses modern data acquisition hardware to track the shaft angle of a synchro transmitter as the shaft is turned through various angles. How difficult could it be to get the absolute angle of a position sensor from the … Continue reading →

In this project, I convert a WW2-era landing gear and flaps indicator into a USB peripheral using a Raspberry Pi Pico development board and eight channels of programmable current sources. This project is similar to my WW2-era engine cowl flaps … Continue reading →
