Lamination For PC Board Etching


If you’ve ever tried ironing laser printed paper to transfer the toner, you know that it can be slightly frustrating. [Dave] sent in an interesting twist on this method. The laser printer is used to print onto paper from a magazine and then the board and paper are both run through a laminating machine six or seven times. From the writeup, it looks like this technique works great. (You’ll probably need a printer with a manual feed tray to get it to print on the magazine paper)

Make A Universal Macbook Air Superdrive


For $99, Apple will happily sell you a slick USB superdrive (aka DVD burner) that only works with the MacBook Air. [tnkgrl] swapped out the USB-IDE interface with a generic $9 unit to make it work with everything else. The generic board required a few mods: relocating the crystal oscillator along with the amputation of its daughter-board that carried an external power connector, usb connector and some caps.

Add A Second Internal Hard Drive To Your Laptop


[Andrew] sent in something we’ve been considering for our 17 inch Dell. He squeezed a 100GB PATA notebook drive into the spare space in his Compaq laptop. He used a USB interface to provide the connection and added a toggle switch to conserve power when he doesn’t need the drive spun up. The mod would be even nicer if you added a keyboard activation switch like [sprite_tm]’s keyboard light.

Non-destructive Breakdown Voltage Tester


This applies more to older vacuum technology than your average solid state hardware, but [Richard] put together an interesting project. It’s designed to test a component for its breakdown voltage without destroying it. The general idea of the ‘BVT’ is to increase the voltage applied to a device until some current leakage is detected. Of course, any device that includes notes on probable arc length in relation to kilovolts is awesome by definition.

Motorcycle Throttle Bodies For Your Car


[Dem_z] modded his Honda VTEC engine to use a set of individual throttle bodies from a 2001 Suzuki GSX-R motorcycle. The fuel injection bungs on the throttle bodies were epoxied shut and the bodies were only used to provide individual butterflies for each cylinder. This one doesn’t quite make our to do list, but it’s definitely a hack.

[bender386] caught my blunder first, so I’ll be sending him a bit of Hack-A-Day swag. In the meantime, here’s a little bonus: Check out this home built anamorphic lens. Native 2.35:1 projectors have started showing up, but they’re insanely expensive. By adding some image processing and a lens to stretch the projected image, you can get full width projection and use all the pixels on the projector.
