Combining SUMP and an Arduino to make a Logic Analyzer

Posted on February 19, 2015 by robertwilkie

Nice write-up, well short one, on using SUMP, an arduino project, and an arduino to make a simple logic analyzer.  Note, depending on the arduino board, you can only do 2-4 Mhz. http://www.mouser.de/blog/arduino-3-powerful-yet-overlooked-uses

GoCupi, cheaper version of Makelangelo, and All opensourced

Posted on February 18, 2015 by robertwilkie

I stumbled on a few more interesting drawbots.  The GoCupi, which had a kickstarter project last summer.  Its around 250 (plus 20 to ship) for the entire kit.  They published all the designs and code from the looks of it … Continue reading →

If I ever build a router table, I am doing this

Posted on February 12, 2015 by robertwilkie

The author build a motorized router table so he doesn’t have to manually adjust it up and down.  He is using an arduino for the controller with a displace and a DC motor to do the up/down.  I have watched … Continue reading →

Poor mans IR receiver

Posted on February 10, 2015 by robertwilkie

I like this idea, the author basically takes a cheap IR LED, some resistors, and one of the A/D lines on the arduino to read IR traffic.  This could be a good way to re-use old IR remotes from TV’s … Continue reading →

Programming an arduino with a cheap bluetooth adapter

Posted on February 10, 2015 by robertwilkie

By cheap, I mean under $5 on ebay.  Basically the authors where using an HC-06 bluetooth adapter and tied the arduino reset to one of its pins so that they could program it over bluetooth.  Not a bad hack. http://morf.lv/modules.php?name=tutorials&lasit=30

Simple arduino O-scope

Posted on January 29, 2015 by robertwilkie

Simple project, I think the screen for it costs more than the arduino.  Its a good intro to getting started. http://www.instructables.com/id/Arduino-TFT-oscilliscope/

Simple Rubberband sentry gun

Posted on January 29, 2015 by robertwilkie

Arduino + servo + rubberband gun = neat sentry gun.  Basically the movement triggers the arduino to trigger the servo that pulls the trigger on the gun. http://www.instructables.com/id/Easy-arduino-sentry-gun/

Hacking the arduino to use the 2nd micro-controller

Posted on January 29, 2015 by robertwilkie

basically they author proposes using the processor that handles USB with the existing one. http://hackaday.com/2014/11/30/using-the-second-microcontroller-on-an-arduino/

Hacking computers with an Teensy

Posted on January 28, 2015 by robertwilkie

Good article on how to use an Teensy to plug into a USB port of a computer and hack it.  What the authors didn’t mention is that Arduinos can get really finicky around acting as a USB HID device.  Or at … Continue reading →

3D print and build your own walking spider like bot

Posted on January 27, 2015 by robertwilkie

Nice write-up and build on creating a spider like robot that walks via control from an arduino.  I took a quick look at the solidworks design, and it looks like it could be adapted for CNC cutouts instead of a … Continue reading →
