My latest 3D printer design uses a belt lifted Z axis that has proven to be a very good performer. The 300x300x8mm MIC6 bed and its support (3.5 kg) are lifted on two linear guides using two steel core belts. The belts are driven by a NEMA-23...
My latest 3D printer, UMMD, uses a kinematic mount, often used to mount lenses and beam splitters on optical tables, to mount and level the bed. The mount constrains motion in 6 DOF, yet allows the bed to expand when heated without creating any...
Not sure what shape I am going with I wanted to ration bars for mini mill and a 3d printer or 2 3d printers.Please advise if there is a solid way as this is the typical box type. I didnt like the prusa and I wanted enclosed.Over 60% of items have arrived...
I am fascinated by the PiDP-8 and the follow-on PiDP-11 computers.Reading listGNU radio 1GNU radio 2avr makefileAnother simple formulabut I could not copy it to a comment.
My usual way to power something with 5V? An old cell phone power supply. My usual way to power something with 3.3V? An old cell phone power supply, connected to a 3.3V arduino micro. That has to stop, so I asked my dad for an old power supply he surely...
Just a quick list of projects I'd like to do in the future:1) Guerrilla Net: Decentralized self repairing anonymized wireless mesh network, using low cost/ low power components. 2) Artificial Virtual Assistant: Running on dedicated server and using OpenCog...
Arduino is a versatile and widely used microcontroller platform that allows hobbyists, engineers, and makers to create all sorts of interactive and automated projects. One of the reasons for the Arduino’s popularity is its expandability through the use...
I recent acquired some Audio Voltmeters that we're going to be throw out. One was working and one was going nuts, so I had a tinker prior to attempting to repair. I tried looking for some user manuals, but got no where without signing my life away on...
Intro Recently I wanted to gain some experience with pneumatics. I came up with a project idea that involves three pneumatics cylinders. Then I began to wonder if these lovely quiet portable compressors with 6l air tanks will be sufficient for driving...
Introduction The identification of the system parameters from a real dynamical system is often required for model control or simulations. In many cases the dynamical system is a PT2 system with the transfer function H(s). In case of D1 up to now i do...
What is MIMO technology MIMO is Multi Input Multi Output technology. By using multiple antennas, it can achieve higher throughput and transmission distance than a single antenna at the same radio transmission power. MIMO is one of several forms of smart...
I was putting together a few more 8042 boards since the original order netted me 5 PCBs and they were panelised 2 per PCB. One didn't work with the same EPROM as the others. Today I compared it with a working board and noticed that the crystal capacitors...
RAMPS: What Is It and What's It For? RepRap Arduino Mega Polulu Shield, or RAMPS, is a board that serves as the interface between the Arduino Mega — the controller computer — and the electronic devices on a RepRap 3D printer. The computer...
Tactical Snacks made his own and it appears to be well designed and made from some parts ordered through Protolabs.http://tacticalsnack.blogspot.com/2017/03/little-stick-vise.html?m=1A pretty cool Stickvise inspired tool was made by pa4tim in the Netherlands. ...
