Here's the null-modem RS-232 connector. The pins are (hopefully) clearly labeled. They're connected as follows (forgive the formatting)
N8VEM ------ 9-pin DSUB
2 (DSR) ------ 4
3 (RX) ------ 3
5 (TX) ------ 2
7 (DTR) ------ 6
9 (GND) ------ 5

Robot3 has an IR rangefinder, one of my STM32 development boards and an xbee radio running the new ZB firmware. There's also a small motor controller board hidden inside the old battery compartment as well as a 900mAh lipo. The rear two wheels are driven by one motor which is speed controlled by a PWM output from the STM32, while the front two have another motor on a rack and pinion that steers them and is driven by a simple high or low signal from the STM32.
The car can be manually remote controlled over the xbee wireless link but automatically backs away from detected obstacles. Alternatively it can simply drive forwards until it detects an obstacle, then reverse away.
Development slowed once I got the parts for the somewhat more interesting quadcopter UAV.

Geeks only should enter Fry’s
Fry's is the mecca for geeks in the silicon valley. Vastly large with an impressive array of items from candy bars, to chips, boards, disks, software, audio/video, media, housewares, you name it. Their prices are good; but, best to watch for your favorite item to be on sale where the prices are quite good.
The downside is that their employees are completely useless. If you have a question or need help--go elsewhere. If you know exactly precisely what you want and are willing to hunt around in the store to find it, it is a good place to go. They could do a much better job of keeping the products neatly arranged.
I prefer the Sunnyvale store and will even drive past the Palo Alto store to go to Sunnyvale. Sunnyvale is larger, cleaner, better organized and less crowded with products and people.
Of interest mainly if not exclusively to me, here's a shot of a power supply I cobbled up to drive nixie numeric tubes. I have several such tubes lying around and have always been too a-scared to build anything out of them because they want about 170 volts before they'll light up and I get jittery about that many volts all in one place. Not so much for being shocked, but for starting fires by inexpertly building things that plug into wall sockets.
I come by this anxiety honestly, since I was a more daring experimenter when I was quite small. As a young boy, at about the age of 5, I looooved cartoons. I couldn't get enough of them, and in those pre-home-video days it rankled me that they were shown only at certain times of day and not just whenever I wanted to see them. My solution was to build my own television set. I didn't know how TV worked, but I figured electricity was the key - which it is, but I didn't realize just how many hoops it had to jump through to do its job. My TV was a little block of wood with a picture tube drawn on it in ballpoint. I drew a character inside the picture frame, and figured that if the block were electrified, the character would get the hint and start doing funny things. I made a power plug out of bare copper wire, bent into a loop that approximated two prongs. The other end of the wire went into a little hole I'd poked in the wooden block. When I plugged it in, the result wasn't funny like I'd hoped, but it was nowhere near as tragic as it could have been - I just ended up with one hand covered with blisters. Not to mention the new respect for wall sockets.
This page shows a clock design that uses a power supply that runs on 12 volts and horks up the requisite 170V (lower left corner of the schematic). I copied it and here's the result - yay! This way, the thing actually plugged into the wall is a nice safe UL-listed wall wart, and there's less chance of my own stuff going up in flames. Of course, there's a fuse between the power supply and the wall-wart, too.
Just out of shot: safety glasses I wore when I first switched this thing on. I may be too careful but oh well.
This power supply, thrown together ad-hoc on a prototyping board, isn't going into a clock. I'm building a tube tester widget first. (which, on edit, I now have - and it is pictured here.)

MintyBoost USB battery pack
This one is in a bigger tin than a standard MintyBoost so it can hold four AA cells. That makes it better for charging an iPhone.
A six story mall with only electronics. I have no idea how many stores... but there are lots. There is a main floor section for the bigger stores, and back alleys for the smaller shops. Shop themes are divide by floors, for instance all the consumer electronics are on one floor, and all custom computer shops on another.
I'm very excited that this picture was used in this article, though I can't read it. If anyone can translate, let me know.
