On this breadboard there are four Kingbright PSA08-11HWA sixteen segment displays that I got from BG Micro some years ago. The PSA08-11HWA comes in an eighteen pin (16 + decimal point + common anode) dual-inline package. Normally that’s great– ideal for use in a breadboard. Note that the rows of pins are oriented 90 degrees from how you’d like them to be– this is really only good if you want your displays to be read top-to-bottom in the breadboard, rather than left-to-right. Turn your head sideways to read this display saying “M7H7.” Controlling these displays is not difficult. However, in this case, where you don’t need to change what’s displayed, it’s absurdly easy.

Click on the photo for some comments on its flickr page. This was also covered on the Make Blog: Monitor Cat bed (Make Blog).

We’ve been taking photos of birds around the south end of the San Francisco Bay. We’ve cataloged some of the interesting ones and put them up as the South Bay Birds Catalog. Pictured above, Anna’s Hummingbird, male. It’s smaller than it looks.
Interactive LED Dining Table
This is our dining table. We built it because we needed a new dining table, and I guess we’re just that kind of people. It has a frosted glass top lit by 448 multicolored LEDs that respond, in a complex and gentle fashion, to input generated by motion above the table while we eat.We showed it off at the Maker Faire. Click on the photo to get to see some other photos of the table construction. Lenore was interviewed about the table at the faire, see Lenore’s CNET inteview.
