DIY space experiments within a ping pong ball ‘satellite’

Pongsat space satellite

Ahhh space. The final frontier. While many people dream of one day becoming an astronaut (and possibly battling aliens or cylons), it’s a select few who actually make it their reality. Fortunately for us, there’s a middle ground that allows the masses to still have some fun in the sky. Enter the “Pongsat” program – space experiments within a ping Read the rest

Beautiful replica Team Fortress 2 weapons

gun

We’ve seen our share of replica props, but [Nathan]‘s replica of the spy’s sidearm from Team Fortress 2 is the bee’s knees.

The build began as an off-the-shelf Airsoft gun. After removing the barrel and cylinder, [Nathan] used Apoxie Sculpt and a whole lot of sanding to turn a stock piece of metal and plastic into something that came straight … Read the rest

24V relay driver circuit

[Glitch] got his hands on a slew of relays which are meant for use in industrial equipment. They are designed to operate at 24V. He wanted to use these with common microcontrollers and instead of buying a driver he designed and built his own.

There’s a few things to consider with a project like this. You need a power … Read the rest

Framing up your electronics projects

[Victor] may be onto something when it comes to project enclosures. He’s using a picture frame to house his electronics projects. This is made especially easy by the variety of sizes you can find at Ikea. Possibly the most important dimension is to have enough frame thickness to sandwich your components between the glass and the back plate of … Read the rest

gifsockets: WebSockets using animated GIF files

gifsockets

Using animated GIF images as a crude WebSocket is an idea we’ve never come across before, but it actually makes a lot of sense. Not in terms of it’s overall usefulness, but just for the fact that the animated files work in a similar way. The nature of these animated containers is what makes it work. A GIF doesn’t tell … Read the rest

Quick fixes for SMD population problems

quick-fixes-for-poor-PCB-work

Here’s a collection of tricks to get over some surface mount prototyping issues the next time you find yourself in a bind. But first we have to address the soldering atrocity seen on most of the components above. [Rxdtxd] admits he’s using a firestick for soldering his SMD parts. The non-brand 40W iron is just about the worst thing he … Read the rest

Adaptive technology used to fly an IR helicopter

adaptive-tech-controlled-helicopter

This gentleman is using electrical impulses from his neck muscles to fly a toy helicopter around the room. The project is a demonstration of the AsTeRICS project which seeks to reduce the complexity of adapting the set of skills a disabled person can use to do a wide range of functions. In this case, controlling the helicopter could easily be … Read the rest
