at 11:51 am. Filed under Cool Gadgets, Electronic Hacks

 

Thanks to Bill Alessi for sending in the details of the NeuroDreamer Sleep Mask that he and Mitch Altman are working on. It is an open hardware project that currently has almost $15K of the $66K of funding needed. The mask has RGB LEDs inside that are controlled by a microcontroller to give you a pleasant sleep experience.  If you are wanting to make your own or a variation of this project have a look at the documentation that they have provided.

DIY Parts Tumbler

at 5:58 am. Filed under DIY Hacks

 

If you use your CNC machine to make metal parts you will most likely need a way to soften the edges a bit before you use the pieces. Neo7cnc built this quick and dirty DIY Parts Tumbler using a plastic coffee can filled with BB pellets, a small motor slowly turns the can and after a few hours your parts have rounded edges and have a nice polished finish.

DIY CNC iPad Stand

at 4:16 am. Filed under DIY Hacks

 

If you have an iPad you know that there will come a time when you need to have it stand on it’s own. Watching a video, reading a recipe, following some online steps for your next project are all times when you will want a stand. The next issue is that you will want a different viewing angle for each situation. There are some iPad covers that have some built in stands but they are not usually very sturdy and not that adjustable.

A fantastic solution is this DIY CNC iPad stand by Planetdaz68 which looks great, have multiple viewing angles and is very sturdy. If there is anything that looks like it could be improved would be the size, it appears that the 4 pieces are permanently glued together. Instead of being glued together it would be nice to see it using a slot together construction which is solid when assembled but can be taken apart when transporting it.

CircuitLab on the iPad – Circuit Design on the go

at 5:13 am. Filed under DIY Hacks, Electronic Hacks

 

When you have a circuit idea in your head you used to reach for a napkin and a pen. More recently you probably launched a browser on whatever computer is closest but what if you could simply grab an iPad. Well that day has come. Now you can design your next circuit design on your iPad which is probably closer to you than your computer. It might not be ideal for large designs since a mouse and keyboard looks to be more efficient for speedy designs but that is a small price to pay for the convenience.

Try CircuitLab Here.

“The CircuitLab web-app is now supported on the iPad! All of the CircuitLab schematic capture and simulation functionality is available on the supported mobile browsers. While we don’t expect most folks to want to design complex circuits on an iPad, we do think CircuitLab on touch-based tablets can be a great addition to a student reviewing or taking notes, editing and testing out a circuit someone else sent you, or sketching out a quick idea when inspiration strikes.”

Make Silicon Metal using a Thermite including Sand

at 4:56 am. Filed under Complex Hacks, DIY Hacks

 

shows us how to Make Silicon Metal using a Thermite including Sand. If you haven’t seen the destructive power of thermite before have a look at this video where some is used to kill a hard drive. If you intend to play with the stuff be very careful and only use it in an environment where there isn’t much around that can’t burn, a kitchen sink would be a bad choice. 🙂 You can see the nice looking  silicon metal at the end of the video which is the result of this burn. Good thing Youtube doesn’t have smell-o-vision since this substance would not smell good!

“The ideal ratio for this type of thermite is 1.67:1 SiO2:Al, but here I use a 9:10:12 mix of SiO2:Al:S (by weight). The ideal composition of just sand and aluminum is very difficult to ignite, so the sulfur is needed for a side reaction with the extra aluminum that provides the heat to drive the real reaction.”
