More samsung caps. Dell monitor repair

Well I found a dead monitor at work.  I cracked it open and found three dead caps.  I replaced them, and viola, working monitor.  Now... I need to ask if I can keep it.

A minty boost.

A few months back, I brought some friends to a Mitch Altman soldering class.  He brought kits, and while my friends were doing theirs, I decided I'd make something. 

Thank you ladyada.  Well, her company provided the kits.  And here's the kit I built Minty Boost. I assembled my minty boost into an altoids tin.  There's room for a spare set of cells in there too.

Shifing a bit. Lots of bits.

Well since I am out of instrument type op amps, I went ahead and dug out my shift registers.  I got it working.. after finding out you need to power all the power lines. 

Here's the instructable I refrenced when I ordered the shift registers: http://www.instructables.com/id/The-74HC164-Shift-Register-and-your-Arduino/

I'm going to need to give this another swing soon.  

Testing sensors.

Well I bought some pressure sensors.  In hopes of building my own altimeter.  When motorola says 5-25mv output, they aren't kidding.  The mpx2010 has an output that seems perfectly tuned to feed an opamp.  Time to learn opamps.

Here's a link to the datasheet: MPX2010
