A Needle Printer

Posted on December 19, 2013 by robertwilkie

This is interesting design, the author for around $200 build a printer that uses a needle to punch holes in paper. This could have potential to make expand into needlepoint someday. http://hackaday.com/2013/12/19/a-weird-kind-of-printer/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+hackaday%2FLgoM+%28Hack+a+Day%29

Even Cheaper outlet Control

Posted on December 6, 2013 by robertwilkie

OK this is even a cheaper solution to control 3 outlets. It uses Home Depot’s RF outlet controller, and arduino with eithernet shield (OK thats not so cheap) and a cheap RF module. http://hackaday.com/2013/12/06/android-and-arduino-rf-outlet-selector/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+hackaday%2FLgoM+%28Hack+a+Day%29 http://www.33snowflakes.com/blog/arduino-wireless-outlet/

Interesting wireless Proximity Sensor

Posted on December 4, 2013 by robertwilkie

Interesting prox sensor build. It uses an atiny, prox sensor, and RFM12B RF transmitter for the build. The article figures the cost for each one to be around $15. How I don’t know (atiny board $10, transmitter $5, sensor $3, … Continue reading →

Nuts, I sponsored another kickstarter like project

Posted on December 3, 2013 by robertwilkie

Its a bluetooth arduino for 20-25 dollars with low power consumption. It sounds promising. and for the cheap price (cheaper than some arduino bluetooth shields) its worth a shot. Oh its more of an ATiny though. https://launch.punchthrough.com/

Build a gas detector

Posted on November 6, 2013 by robertwilkie

The author build his own gas detector, partly due to costs of commercial one I gather, using an arduino no less. http://makezine.com/video/projects-with-ryan-slaugh-diy-gas-leak-detector/

Arduino TV Annoyer

Posted on November 1, 2013 by robertwilkie

Good write-up on how to build a TV annoyer, thought using a full arduino seems overkill. The rest only costs 1-2 dollars in parts. http://www.instructables.com/id/150-Arduino-TV-Annoyer-Turns-TVs-on-when-you-/?ALLSTEPS http://lifehacker.com/how-to-build-an-arduino-tv-annoyer-1455875485?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+lifehacker%2Ffull+%28Lifehacker%29
