Electrochemistry: Liquid Power Resistor for 2000VAC
I'm setting up a test circuit and I need a 100k resistor that can handle 2000VAC for a few seconds. I was going to run off to the local surplus shop but got the idea of making a liquid resistor. Saves a trip. I added some salt to water and got 100kohm. Copper electrodes (all I got at the moment). Questi... 17 Mar 2010 19:59

A strange PIC problem
I was writing a driver for a graphics LCD for PIC 18F14K22. That went OK: ftp://panteltje.com/pub/graphics_lcd_driver_img_1_1861.jpg But I wrote it is asm, so it needed a lot of typing, even more so because this display CD-19-HG1286418C has a strange driver chip S6B0108 that comes from a planet where x is vert... 18 Mar 2010 20:07

Let's design a fake Perpetual Motion machine
I was thinking about all the fringe-science "Magnet Motors" and found myself reasoning thus: suppose there's a way to power a flywheel by slowly demagnetizing some permanent magnets. Wipe out the magnets' stored energy, and inject it as KE into the flywheel. If possible, this would explain a large number of biz... 17 Mar 2010 23:25

Quad LVDS to LVPECL?
Does such a chip exist? I can't find it.

Toshiba laptop aggravation
I have three Toshiba laptops due to ignorant purchases over time. All three have a mousepad in front of the keyboard which has an auto-click function - if you tap it with a finger, it moves the focus to the current cursor location. The problem with all three is that during normal 10-finger typing, thumb movement ne... 17 Mar 2010 03:36
