Another Scott Kelby Worldwide Photowalk is coming up soon. This year it will be October 11 and one is already set up for downtown Charleston. I’ve participated in a fewprevious photo walks and they’ve always been fun events. It’s a chance to meet and hang out with some fellow photographers, explore the city and get some great shots.
Previous years have seen other photowalks in North Charleston and Summerville, so if you aren’t able to make it to the Charleston photowalk, try to organize one near you.
Continuing the tradition of making radiographs of my electronic things, I got a radiograph of my new Nexus 5, the DDS modules and the Arduino Pro Mini.
The Nexus 5. The battery takes up a good bit of the space inside. The square object to the right of center near the top is the camera module. The SIM card tray is easily visible below that. The boards look pretty crowded (click for the jumbo sized image).

The AD9850 modules. Not a whole lot to them. The crystal in each module is easily visible as the rectangular object on the left. The AD9850 chip is in the middle.

Sparkfun Arduino Pro Mini. Not a whole lot to this either. There’s the AT Mega 328P chip in the middle, and at the top is the reset button.

All images were acquired using an 8″x10″ cassette. X-ray technique was 80 kVp, 5 mAs with the small focal spot (0.6 mm). Source to image distance (SID) was 172 cm, and the object to image distance (OID) was about 100 cm giving a magnification factor of about 1.7. This results in some magnification blur, but at this magnification, the Nexus 5 takes up pretty much all of the cassette.
Jason/NT7S was doing some more shack cleaning so I took the opportunity to buy an Arduino Pro Mini and some AD9850 DDS modules he put up for sale.

No immediate plans for either of them yet. I’m looking forward to learning more about the DDS modules and figuring out how to use them with the [Net|Ar]duinos.
