Project 158 Day 70.
Working on getting Project 158 back up to snuff and fiddling with adding Flickr and Facebook upload buttons to Picasa.
Macro of some 'old school' electronics, meaning pre-surface mounted devices and computer chips. Circuit board from an old battery backup emergency light.
Digging through the photo archives, found this fun side project.
Back in 2001/02 my web site had a little interface where you could turn on or off "pixels", and design a little pattern that'd be submitted and shown to the next visitor on the site. Thousands were submitted. The black-and-white thing in this case is one version of the web UI which was shown.
In 2002 I finally got to making something originating from the internet "real" with this project, having some hardware do something with this data. Andrew Beley, a friend and roommate studying electronics engineering, designed the hardware, and I did the software. Basically a grid of transistors which took 160 of the 8-bit outputs from the parallel port, and lit up accordingly in a 5x32 grid. The software would poll the web site and grab the latest "image" periodically.
I also wrote a simple socket listener which would allow people to issue commands to the thing via telnet (through the host computer.) You could write messages and they'd scroll, etc. I guess I had more time on my hands back in the day. ;)
Here is the arduino talking to the soundgin using software-driven serial communication over arduino pins 2,3 and 4. The yellow wire is for a pin called CTS which I believe is used for the soundgin to tell you that it is ready to recieve serial commands or not. Note that there is no ground wire from the arduino to the breadboard. In practice I think that you really need this so that both ends of the communication have a valid reference. These two boards have separate power sources and communicate using logic level rx/tx @5V. When this picture was snapped the arduino was running a program that iteratively plays each of the 30 predefined sounds, one every 5 seconds forever.

It looks to me like Sony puts a fairly thin, almost like an aftermarket type screen protector on the RX100 screens and the edges of the protector are exposed. I am curious if anyone has experienced any chips or damage to the edges of the screen protector?
I picked this little guy up at the local Goodwill for $1.99. I was hoping to find a Technics turntable but maybe next time.
Just like every other speaker found in a place like that some jackass came along and poked in the dust cones but of course that's nothing a little bit of electrical tape can't fix.
This is the encoder of a 12v DC motor. This particular encoder has 3 wires, not including the two wires used for the motor. I'd really like to know more about the encoder as these are nice motors!
D'you guys have any idea?
