Tools, Parts, Kits for DIY'ers - Curious Inventor
My Inventor Club is moving from a typical hacker-space sized building to a massive new location. The club will offer many of benefits of a hackerspace such as a full machine shop, laser cutters, 3D printers, space to build, etc., but also has enough room to be much more for the Atlanta community. They're planning on renting space to small hardware-based startups, serving as a co-location workspace, and maybe even holding conferences (mini makerfaires?). The wooden floor picture looks large enough to comfortably hold 100 makers all working with plenty of elbow room to spare, and they've got three floors that size, plus conference rooms. And even more mind-boggling, the 2nd picture shows another "factory" building big enough to hold a cruise ship or small factory. They're planning on having several car bays for auto work, amongst many other industrial machines.

Dank Grbl is a free, open source, high performance CNC milling controller written in optimized C that will run on a straight Arduino. Get the code at Github | Follow Grbl on Twitter MIT Center for Bits and Atoms designed a beautifyl snap fit CNC machine controlled by Grbl. Nortd Labs runs their open source laser cutters with a Grbl-based firmware Who shoud use Grbl

The Fabulous Logic Analyzer #1 What is a logic analyzer? A logic analyzer is a device which can monitor the high and low states of several input lines of a digital logic. It is useful for debugging digital circuits such as bus transfers, etc. You can imagine a logic analyzer to be something like a digital oscilloscope.

As a new guy I totally sucked at grinding lathe tools. It’s almost painful to admit how many stubby, misshapen, multi-faceted, overheated and just plain ugly lathe tools I made back then. The amazing thing is that some of those tools actually worked as well as the pre-ground tools that came with my lathe. I started to believe those guys that tell you, “… just get it close and it will work.”

simplelogicanalyser - uvasux Simple Logic Analyser The idea is to build a circuit and computer software that will turn my computer into a logic analyser. I'd like to be able to inspect logic values within a digital circuit. This circuit is unbelievably easy: it only uses one IC and needs no external power supply. The logic analyser (schematic) is basically a buffer between the user's circuit and the parallel port using a 74hc4050 hex non-inverting buffer.

Carrion Sound - .url Grbl development log First complete job … completed I finished a little Air-app to stream complete jobs to the Grbl and render the result. This is the first “full scale test” running some 7000 lines of sample G-code I scrounged from this thread on CncForum. The Air-app feeds g-code to the microcontroller one line at a time, while the microcontroller generates the steps and feeds them back to be simulated in the Air-app. Everything seems to be working perfectly - the only thing missing now is a test with real steppers on a real machine. You can get the code for the Air-based test-harness at the github-repository

A logic analyzer using the PC's parallel port. Last changed: 10/09/2009 16:52:25 Introduction. A logic analyzer is useful in electronic development and debugging, especially where fast logic circuits are involved with lots of signals whose relations have to be verified or examined. A logic analizer is a like a recorder for digital signals. CNC Router Build – The Stand The stand for my Solsylva 25x25-inch CNC router is made from 1x4-inch pine boards. Two of the supports are hinged so you can fold the router down so it takes up less storage space. Building the stand for my Solsylva 25×25 CNC router was pretty simple.

» PIC18F2550 USB HID Oscilloscope This is a project that I’ve been planning on putting together for a long time. After creating an oscilloscope using a PIC12F675, I wanted to create a simple and effective USB oscilloscope using the higher performance PIC18F2550. During the development of this project, I learned quite a bit about USB HID communication, which allows me to quickly and effectively communicate with the desktop computer. Retracting Key Ring Corrals Chuck Key Noticed this write-in tip from Matthew Hakeman in the most recent issue of The Family Handyman. Googling discovered the title image in a thread over at, from user evintho. Looks like he’s put a metal strap around the key between the handle and the teeth.

How to debounce a switch How to de-bounce a switch using CMOS & TTL It has come to my attention that there is a definite lack of understanding on how this simple procedure is achieved. Especially for low numbers of switches in non-microprocessor controlled devices. If the number of buttons you require on your front panel numbers less than 16 then this is how you get a clean button press.
