Make you own Arduino Metal Detector

Posted on July 26, 2013 by robertwilkie

Pretty cool build, using an arduino to filter out the noise.  The only thing I can think of that would be nice is a better set of directions on how to build this. http://dzlsevilgeniuslair.blogspot.dk/2013/07/diy-arduino-based-metal-detector.html

Another BareBones Arduino for $5 in parts

Posted on July 24, 2013 by robertwilkie

The author writes up directions on how to build a simple barebones arduino that will fit on a breadboard for about $5 in parts.  The board looks pretty nice (he did a good job building it).  Me, I might buy … Continue reading →

Make the TP-Link look like a real Arduino Shield

Posted on July 24, 2013 by robertwilkie

As the author points out, wireless cards for arduino can run you 50-60 dollars.  So he not only adapted the TP-link for the arduino, but converted it to fit on the arduino like an arduino shield.  Me, thats too much … Continue reading →

Cool tank like seed spreader

Posted on July 22, 2013 by robertwilkie

But I would never build it.  It came out of a joint work with PopSci and Instructables. But its really small I think thats a hand spreader its using).  And the parts are ALLOT of money, just the wheels I … Continue reading →

Use a TP-Link for a Arduino ethernet shield

Posted on July 18, 2013 by robertwilkie

Want wireless ethernet access for your arduino or TI MSP?  Use the TP-Link TL-WR703N as written up in the directions in the link below.  These sell for around 20-30 dollars, much cheaper than a wireless shield for arduino (50 ish)   http://www.martinmelchior.be/2013/07/use-tp-link-tl-wr703n-to-send-arduino.html?m=1 … Continue reading →

Arduino lib for TI’s cheap wifi chip

Posted on June 27, 2013 by robertwilkie

Someone ported the code for TI’s wifi chip to Arduino, which is very cheap for WiFi (around $10).  The eval board for it is $35, which I believe is cheaper than the arduino wifi shield, but not cheaper than some … Continue reading →

Have a 3D printer, may an Eggbot

Posted on June 25, 2013 by robertwilkie

OK I now need to get my 3D printer working again.  Well at least before easter so I can build this.  I have all the parts and this would avoid having to buy a kit.  🙂 http://www.instructables.com/id/3D-Printed-Arduino-Controlled-EggbotSpherepot/

A shield for RPi for using Arduino Shields

Posted on June 24, 2013 by robertwilkie

Nice looking shield for Raspberry Pi to use arduino shields, seems well documented to.  BUT… at 23 Euros (around 45-50 US dollars), plus S&H, I can just by an arduino and have it talk to the RPi. http://www.open-electronics.org/expansion-shield-for-raspberrypi-compatible-with-arduino/
