Start by removing the weight and making the chain into a loop. The P2-Winder sits at the bottom the the chain loop. The chain lies in a toothed chain-wheel. A motor and gearbox can turn the wheel. The original clock weight hangs below...
When I designed my latest coreXY 3D printer, Ultra MegaMax Dominator (UMMD), I wanted a tall Z axis but I didn't want any possibility of Z-wobble in the prints, usually caused by either bent or off-center lead screws. It took a few attempts, but...
The initial idea was to make a life-size version of the actual game Operation. At the first meeting, however, an idea was proposed to keep the spirit of the original, but make it instead an alien autopsy, with the patient being an alien and the ailment...
Open-Source Robot Building Kit and Development Environment The main products in this robot building kit are: 1) Ethernet Modules (PCBs) a) EthMotors - a Microchip PIC32 controls up to 12 motors (up to 2.8A each, using 12 Texas Instruments'...
Introduction Op amps are well known for their utilitarian prowess, performing many vital tasks underpinning analog circuit design. They add, subtract, integrate, differentiate, and amplify with great precision! That’s all well and good…...
I have designed this router and system to run a PFsense VM on ESXI hypervisor, using my laptop for SSH or on-network access along with a display attached as well.Please see: The updates and details for this project represent my experience making...
Note: this just got a major re-write. The heart of the MultiSpork (and the inspiration for it) is the new Maxim MAX11300, which is sort of a magical little chip. It has twenty I/O lines, each of which can be an ADC, a DAC, or a GPIO line. It can do these...
The EVI (Electronic Valve Instrument), a trumpet-style electronic musical instrument in the Wind controller family, was developed in the early 1970s by inventor and musician Nyle Steiner. The EVI is an endangered instrument and the EVI player is an endangered...
I'm documenting this retro-actively, so I'll be adding more project logs over the next few days/weeks. The first few iterations of the power supply are done. I ended up with a couple of variations on the theme, and I am still tweaking them to get the...
Short Description 40x40 t-slot profiles form the 470x500x550mm (HxWxD) sized frame. The large build volume of 300x300mm can be used with up to five Materials. This is achieved by water-cooled exchangeable tool heads. The tools do not have their own cooling,...
Link to the github page: https://github.com/Trakyan/BevelCNC/tree/masterHere is a little rundown of the machine I plan to build for myself. I'm using M5 hardware, just because I happen to have a bunch of it on hand. M5 seems like the good size to...
In the company where i work, we have a personal badge that we have to keep visible and we use it to open the office doors, like in most of the other companies. After breaking my badge holder, i came up with the idea of make a badge holder with PCBs and...
This has been worked on for 6 months now (on-off, like all hobby projects). The 3D design is in OpenSCAD, all parts are printed, except for a few 10x10mm profiles for the sliding servo carriage. Well, the clockface is printed on paper, too. The...
A List of Resources: Wood: Look for a sturdy and durable wood material that is suitable for your project. Consider the thickness and type of wood, such as oak, pine, or plywood, based on your design preferences and desired level of durability. Saw: Choose...
This project is actually just a "quick hack" to monitor my energy wirelessly. As I have ordered approx 20-30 nrf24l01+ dongles, I have plenty wireless dongles to spare. I use a simple MSP430 launchpad with the MSP430G2553 microcontroller to give the...
