Game Time: What did I Build #2!!!
Ok ladies and gentlemen...This round 2, the finale round for this semesters of "What Did I Build".....
If you remember last time, Travis described the workings of the last design and won the GRAND PRIZE in which he turned down. Lets see if he can do it again. Since one person seems to not be interested in a free beer, I can assum that the rest aren't either so no prize for this round.

Not to be a dick or anything, but your breadboarding skills suck the big one. If you're doing work with sensative (to noise, that is) analog signals, perhaps with capacitors, perhaps in the RF area, making circuits like that will cause things to not work (due to lead capacitences, noise induction, etc.). Trim component leads to size, tidy up wire routing, trim wires to size, and if you're so inclined, color code wires.
I would suggest picking up a copy of "Getting Started in Electronics" my Freest M. Mimms, III. Its a Radio Shack book, Cat. No. 62-5003. Pages 96-99 have some descent circuit assembly tips.
The only reason I bring this up is that I can't count the amount of time that I had wasted during my early undergrad days as a EE major - time wasted because of stupid little things being wrong with breadboard assembly, or noise getting in the system and screwing things up (I recall an incident with a transistor from my first EE class ever - 8 hours! - and the TA couldn't figure out what was wrong since everything was wired correctly).
Are you building something off a schematic? It would me easier (yet not nearly cost effective) to have a PCB made - assuming the schematic is good, the build quality will be pretty high; plus knowing how to do PCB layout is a pretty damn useful skill.

How's this one... what does this little circuit do:

The white boxes are where I cut out the title of the pic, and other information that *might* give it away.

And the winner is: Steve. Its a wideband O2 monitor with numeric (xx.x digit) display - and it also simulates a narrowband sensor so you can run your stock ECU with no problems (and only have to install one O2 sensor)... plus its small (see dimentions in pic), and comes with a nifty brushed aluminum case (flush and surface mount faces available). Pretty neat, eh?
