The initial aim of this project was to not throw out my Robox printer as e-junk and try to recycle it. This will be an ongoing challenge to many environmentally committed 3-D printer enthusiasts. The Robox design had been brilliant, but as it aged I...
Vector Drawing Machine, Number 3 BackgroundBeing an Engineer, I have always been drawn to the Russian pragmatic method of naming new products. While some idiotic Western Marketeer might name a small CRT based gaming machine ‘The Vectormatic Score-Master...
Inspiration The release of the Raspberry Pi pico finally tempted me away from 8-bit AVR development under Windows. These are a few notes on my experiences in case they are of use to anyone else. Let me say straight away that all I've done is followed...
A while ago I built myself a DIY 3D printed CNC machine called the MultiBot. Recently I picked up a NEJE 30w laser module and have been trying to explore how to use this diode to the best of its abilities. Air assist has come up and I have...
What’s in a lab? I had to make some decisions as to what tools and components would be crucial to making this thing as useful as possible. There are quite a few tools that are versatile enough to be a part of any laboratory, and there are some great...
Brief (yeah, right...) recap... What I need is a somewhat-accurate reading of the CPU frequency so that I can bitbang a bidirectional UART. This differs from my previous "UARto[S]T" (Universal Asynchronous Receiver to [Synchronous] Transmitter),...
I never seem to get it right. It makes /so much/ sense, and yet completely eludes me whenever i try to apply it in even the tiniest way outside the norm. In fact, now I'm at a complete loss for how ft-lb or A-hr work. So, I can't really explain how this...
Files This project is fully open source. All digital files relating to this project can be found below in the files section. Here are all the files that I have included. Bill of material (with links and prices)All STEP filesAll the Arduino Libraries...
Robotic Bartender This weekend you can make your next cocktail party an even bigger success by building this DIY Cocktail Mixer using Arduino. The best part about the project is how creative and unique it will be for each individual maker!...
Here's what you need, for sure. This sounds like a lot more than it is, mostly by way of discussion. You really don't need anything more than what's listed here.A power drill of some sort and drill bits. Corded or cordless doesn't really matter,...
2014 - Birth Of A Game Cabinet Our game collection was stored in various milk crates and other storage chests throughout the house. My wife suggested shopping around for a tall cabinet and after looking around I started to get an idea. I had made...
We're Now At A Million Plastic Bottles Per Minute - 91% Of Which Are Not Recycled This presents an overwhelming challenge in responding to an exponential increase in recyclable yet un-recycled products... Wouldn't it be nice if every maker could reuse...
Back in the early 2000's I had a project which went quite smoothly, until suddenly, and for months, eluded the heck out of me, and still that bit haunts me to this day. Prior to that project, I'd been doing stuff with AVRs for years, fancied myself pretty...
10/06/22 update: I didn't provide enough details on this project before, so I'm editing this for clarity and to cover a lot more specifics. It turns on!!! My car is very special to me, and I spend a lot of time driving it, but the one issue that always...
PySpectrometer2 The second incarnation of the Spectrometer project! This is a more advanced, but more flexible version of the original program. It changes the spectrometer from educational 'toy' to serious instrument, which can easily compete with commercial...
