From the bright boys at NASA., a simulator for your model rockets. Very cool! Plug in numbers for body size, type of nose cone, motor type and launch conditions and it will simulate the altitude your ship will obtain.

Fire Starting Flashlight
Now I can see why the British call them ‘torches’! A modded MagLite, some high power batteries and a projector bulb will get you one hell of a hot flashlight. WARNING! Do not use this to read books under the covers, that is unless you sleep on a stone slab and your sheets are made of asbestos.

Chart of Astronomical Distances
Just how far away are planets, stars and nebula to our planet? Very handy for planning your next vacation.

DIY Nikon D70 Infra-red Remote Control
This is just the thing you need to have in your camera bag. I have one that I bought online but if your not in a rush and have the skills to solder this would be a clever little device to have around. Very handy for tripping the shutter when your doing macro work or your doing long exposures where camera vibration is a bad thing.
This is a replacement for the sparsely available Nikon ML-L1 and ML-L3 IR remote controls. Like the original remotes, this very simple circuit allows you to remotely release the D70 shutter or do a bulb exposure while avoiding camera shake. It should also work with other Nikon (d)SLR’s, provided they are supported by the ML-L1 or ML-L3. The IR sensor of the D70 is behind the round black plastic spot above the D70 logo on the body.
DIY Analog Video Synth
Who says that you can only circuit bend audio devices?
Video synthesis tends to be dominated by digital technology these days however analogue video synthesis techniques can still offer a great many advantages in terms of aesthetics, performance, simplicity, and adaptability. Not to mention the non-linear surprises which can come from working in the analogue domain. This "VGA Expropriator" will be the first in a series of proprietary analogue hardware devices which seek to explore the possibilities of digital/analogue hybrid technology in video/audio performance and studio production contexts. The first offering here is essentially a new design with its creative process making ample use of circuit-bending methodologies.
