This project started out pretty simple - I wanted to control my TV, receiver, Apple TV and Foxtel set-top box from my homeassistant.io setup.Of course, feature creep crept in and I decided to add CEC over HDMI.There are three parts to the project:The...
Printed Circuit Board The main component of the PCB is the Hi-Link AC-DC converter. The PCB is designed to accomodate either the HLK-PMxx or the HLK-5Mxx series component footprint. They are available in several voltages. You can find them on Amazon,...
This project uses two RC circuits, one implemented as a timer, and one as part of an oscillator in order to obtain both a fixed duration for a strobe as well as a strobe frequency. Rather than use a 555, I used a quad NAND and a handful of discretes....
Background When we think about the dawn of the personal computer era, names like Apple, Commodore, Radio Shack, and Sinclair come to mind. That's because these companies were the big winners in this new market, selling millions of personal computers...
I needed to connect some more test equipment to my LAN. Currently this is done with individual Serial-to-Ethernet adapters in takeaway curry containers but this was getting ungainly and wasteful of internet ports. Commercial 8-port RS232 to ethernet...

Some time ago I bought a BoardUp Lite skateboard (https://goboardup.com/shop/boardup_lite/) and I found it to be a fanstastic skateboard! It's light and small but it also feels like a normal longboard while riding it. But just like any skateboard, it...
As an inhabitant of a big European city and a maker preoccupied with some environment-friendly thoughts, finding a convenient way of transportation turns out to be a heck of a conundrum. Cars (electric or not) are doomed to decline as a commuting solution....
My father likes to create models of all his past vehicles (mostly boats), then he asks me to turn them into running remote control models. He now has a sail boat, 2 speed boats and recently presented me with a canal boat to electrify. I did create...
Ventilation & Carbon dioxide: Good ventilation is important for indoor air quality, especially for reducing the concentrations of pollutants and airborne viruses (looking at you, COVID-19!). Measuring carbon dioxide (CO₂) can be a useful proxy...
I used a plastic shell with a 2mm stainless steal plate as a front. Coresponding holes for display and buttons were drilled out. I would have prefered to go with a 3d printed case, but i dont have one at home, soi went with the diy method cause of costs....

High voltages, like the one in this design are dangerous. It is unsafe for children or users of pacemakers or similar implants. As noted, the Boost Power Module is the key to the design. It produces a 20,000 volt output from a 3.6 to 6 volt...
PhalanxA clock built with six authentic soviet vacuum fluorescent display (VFD) tubes, a custom designed circuit board, firmware and 3d-printed case It features 6 Authentic ИВ-6 (IV-6) Soviet VFD tubesWifi connected setup and control with an ESP...
Twilight switch clock The clock uses a Real Time Clock (RTC), a light sensor, an Arduino Nano, a LCD display and a relay to make it work. For durability reasons an aluminium case is used, however it could also be placed in an 3d printed case. Construction...
