As you probably know, one of the reasons that drove us to build Watchduino in the first place was the prospect of creating a smartwatch that you wouldn’t need to think about recharging. We achieved this with the first Watchduino, using techniques like...
The CF Card was obtained on March 8th, 2017, and the CF to IDE adapter was obtained on March 9th, 2017.Just a warning: this is a longer log post compared to the others.IDE is one of those legacy technologies that you see everywhere in spite of its age....
Yesterday set up this project and filled in info to get it up to where I was at. Today started fleshing in the design decisions to get things moving further. After writing up a bunch of info for the Details Section, I think I'll use this log section...
In the first log I investigated the methods of growing bacteria, and extracting ,then purifying their PHA granules into usable plastics! A major roadblock is the usage of toxic solvents in the extraction and/or purification process. This means...
Introduction It's been quiet here for a while and it might be a good moment to provide an update describing what's been done during previous months. I've been working on Xlingtool, a plugin for GIMP based on LCD Image Converter and a new way to draw...
What I BoughtI bought the cheapest laser galvo mirror set that I could buy, that also had reasonable shipping. I ended up with this one.The kind I boughtThe set comes with the twin galvanometers, mounted on a metal block, two driver boards and a...
Thursday 09:05, 08/12/2022 Well, as I said on the previous Project Log 12: hydraulic mechs are not viable. The thing is that I calculated the hydraulic artificial muscle mech, not hydraulic cylinder mech. THEREFORE, I will try again to...
Here's the circuit used to drive the LED. A PIC12LF1571 periodically wakes to pulse the gate of an N-channel MOSFET. The MOSFET allows current to build through a 1 mH inductor; once the MOSFET shuts off, the inductor discharges through the LED to create...
I finally started to do something that I've been wanting to do for over 20 years: use a logic analyzer to figure out how the DCC-175 communicates with the PC. It didn't go so well but I fixed my mistakes. If you want, you can skip this...
I know it's been quiet in this corner for a long time. But lately there have been some exciting things happening to this project. So here goes! ---------- more ---------- First of all, the most exciting news: I found a cable that fits...
It took 1.5 months to learn anything about my dad. It took 2.5 months to finally hear him live over the phone. There is a difference between not having the chance to call your family, and not being able to and not knowing if you will be able to. ...
Since the beginning of this project we have designed and tested different electronic designs, this log compares them and highlights their features, cost and dimensions. We recently design EJA M v1.0 with the goal of replacing the previous designs,...
I'm sitting down to start creating a video I started a while ago and never finished. I'll be doing it on the Pi 400 of course. Pi 400, Vilros Pidock 400, in ear monitors, kdenlive, Audacity, extra patience. The first step is to review all the footage...
01/04/2023, Saturday, 20:19 Before anything, this is not a joke-log or any kind of prank, just hear me out. So, I was thinking about a lot of things and I finally understood that I was making a huge mistake when thinking that "making mech/exosuit...
Here's the latest version using the inductor boost topology, along with the matching programmer board. With a barebones program loaded, this particular unit should glow for almost seven years on a CR2032 (consuming 3.6 uA) - it runs for seven seconds...
