Mini arcade cabinet looks as good as the real thing

mame_cab

[Ed] had a netbook he no longer needed and decided to make it into a mini MAME cabinet for some of his family members. MAME cabinets are pretty plentiful, but this one was so nicely done, we wanted to share it.

He removed the monitor from an EeePC 901 in order to get some precise measurements, then went about crafting … Read the rest

DIY Scanning Electron Microscope

[Ben Krasnow]  has recently completed a home-built scanning electron microscope and has posted a video of it in action on his blog.

The build itself was done quite creatively using many off-the shelf components. We particularly like how long threaded brass rods were used not only for the supports, but also to maintain column alignment and fine-tune the spacing between … Read the rest

[Akiba] and the crew at Tokyo Hakerspace are still hard at work trying to help out their fellow countrymen after the recent earthquake, tsunami, and ongoing nuclear crisis in Japan. You may remember the group as they are behind the Kimono Lantern project we featured last week. This time around, their efforts are focused on getting usable information out … Read the rest

Fusion reactor wins science fairs

[Will Jack] built a heavy water fusion reactor and then won district and regional science fair projects with it. Someone give this man a job!

We looked in on his fusion reactor about a year ago. At the time he had managed to build a magnetic containment field but didn’t have the voltages or the deuterium necessary to achieve fusion. … Read the rest

DIY Low-power PSU for home server use

[Viktor] decided to replace his old power hungry home server with a model that is much easier on the old electric bill. The new motherboard uses an Intel Atom chip and consumes far less power than its predecessor. He figured there was no reason to use a bulky ATX power supply when all he needed was 12V for the mainboard … Read the rest

Learn the geometry to draw an analog clock on a graphic LCD screen

Does the image of the clock above make you shutter with fear because of the math you’d need to use to recreate your own version of the project? We certainly understand that High School geometry is becoming a very distant memory, but it’s really not as hard as you think. [Janw] built this analog clock using a graphic LCD and … Read the rest
