HA another harddrive grinder build.
I get a kick out of these harddrive grinder builds I see every so often. The author did a good job writting it up. Me…I think $10-20 will get the same thing at harbor frieght without the need to make … Continue reading
Build your own PVC based Rubberband Machine Gun
I remember a kickstarter project to build a wooden version of this. This is much cheaper solution thought. Maybe $20 in materials. This could be a fun project to build with kids, and I see a few spots where we … Continue reading

Using an LED to detect RF signals
OK this is a first for me. The author uses an ATiny with an LED to detect RF, Radio Frequency, signals. http://hackaday.com/2015/04/26/using-an-led-as-a-simple-rf-detector/

And more on Xerox not looking too good in stock
It seems 3D systems, which bought out a bunch of Xerox’s 3D printing tech, and Xerox, both had a lousy week last week. http://www.wsobserver.com/stocks-you-should-dump-3d-systems-corporation-nyseddd-xerox-corp-nysexrx-hanesbrands-inc-nysehbi-guaranty-bancorp-nasdaqgbnk/7211784/

$5 LED lanterns
This has to be an interesting build. The author uses PVC pipe (painted) to be a “stand” and then ping-pong balls to diffuse the light from the LED. Nice build (I figure closer to $10 to build than $5). Not … Continue reading

Use a big steel bucket for a hose holder
I like this project, why? Well the typical “hose rollers” leak after a few months. So they are nice in rolling up the hose, but a pain if you don’t want the water leaking out with them. So instead I … Continue reading
3D Printed slider
Well made with PVC pipe for “sliding” on. The author built this for DSLR cameras. Me…this could make a good build for a simple CNC for kid projects. Oh and I don’t think the author factored in the plastic in … Continue reading

3D print Z-Axis for CNC
Nice build for an almost all printed Z-axis for a CNC. Not so sure I would do this over building one from other materials. I would be a bit worried about the flex on the plastic. The author geared this … Continue reading

Good tutorial on using Nokia 5110 with an Arduino
Nice tutorial on using this display with an arduino, these have come down allot in price ($3-4) lately. Which is cheaper than some of the other arduino based displays I have seen out there. I am curious how much space … Continue reading
Simple personal solar powered A/C
Nice build with water cooler jug. The only issue I see if finding a fan (if you are building something like this from scrape) that puts out a decent breeze at 5 volts. Most of the fans I have are … Continue reading
