A Deadbugged GPS/GLONASS/Geiger Counter

via Hackaday » hardware

So you think you’re pretty good at soldering really tiny parts onto a PCB? You’re probably not as good as [Shibata] who made a GPS/GLONASS and Geiger counter mashup deadbug-style with tiny 0402-sized parts.

The device uses an extremely small GPS/GLONASS receiver, an AVR ATxmega128D3 microcontroller, a standard Nokia phone display and an interesting Geiger tube with a mica window to track its location and the current level of radiation. The idea behind this project isn’t really that remarkable; the astonishing thing is the way this project is put together. It’s held together with either skill or prayer, with tiny bits of magnet wire replacing what would normally be PCB traces, and individual components making up the entire circuit.

While there isn’t much detail on what’s actually going on in this mess of solder, hot glue, and wire, the circuit is certainly interesting. Somehow, [Shibata] is generating the high voltage for the Geiger tube and has come up with a really great way of displaying all the relevant information on the display. It’s a great project that approaches masterpiece territory with some crazy soldering skills.

Thanks [Danny] for sending this one in.

Old Fluorescent Fixtures Turned Into Fill Lights

via Hackaday » hardware

The Tymkrs are hard at work setting up their home studio, and since they’ll be shooting a few videos, they need some lights. The lights themselves aren’t very special; for YouTube videos, anything bright enough will work. The real challenge is making a mount and putting them in the right place, With a shop full of tools, making some video lights isn’t that hard and easily translates into a neat video project.

The lights began their lives as large fluorescent fixtures, the kind that would normally house long fluorescent tubes. The Tymkrs cut he metal reflector of this fixture in half, capped the ends with wood, and installed normal incandescent sockets in one end.

The inside of this reflector was coated with a reflective material, and a beautiful rice paper diffuser was glued on. The Tymkrs attached a metal bracket to these lights and screwed the bracket to the ceiling. There’s enough friction to keep the lights in one spot, but there’s also enough play in the joints to position them at just the right angle.
