Wrapped around this cardiac balloon catheter are temperature and EKG sensors and LEDs. The wires are stretchable coils.
It is manufactured with a lift-off MEMS process. The etched silicon is then stretched and attached to a polymer backing. Silicon usage is minimized over the substrate and the ensemble is quite flexible, to survive inflation and deflation of the balloon.
I got this board because I needed a development platform for one of my microcontrollers. At the same time, I ordered an Atmel AVR ISP MkII programmer, which I wanted to use because it is a native USB device and is a little easier to use on the Mac. Of course, it turns out that the programmer has a different type of ISP connector than this board was expecting.
So, this is a Olimex development board for Atmel AVR 20-pin microcontrollers, modified it to accept input from the AVR ISP MkII, which has a six-pin output connector. The header that I added is at the bottom of the board.
Read more about getting started programming the AVR on the Mac here.
The Teensy gets tucked into the back of the suit, and then the little connector that helps keep all the parts of the suit together slides in thanks to some channels I cut for it. The battery cables then get tucked in, and the battery itself slots into a hole I drilled in the connector piece. There wasn't quite enough room to keep the whole "cockpit" part, so I cut the bottom off of that to make space for everything.
Despite staying in a room with five other backpackers, I have been sleeping well. The mattress and pillow are firm; my earplugs keep the noise out; and the sleeping quarters are as dark as a cave when the lights are out, and only as bright as, perhaps, a dreary rainy day when on. All in all, St. Paul's is a excellent place to stay for the gregarious, adventurous, and penurious city explorer - couchsurfing may be a tenable alternative; I'll test for next time.
The Silvertone 1205 (made by Arvin Industries in the U.S.A.) is too large to be considered a shirtpocket radio yet too small to be considered a coatpocket radio. Nonetheless, it is well made, sounds great and is an attractive set.
The 1205 features a lot of chrome trim, a reverse painted dial area with a spinning atom and a kick stand for support.
Silvertone was the brand name for electronics sold through the Sears department store.
The Arduino Ethernet Shield 2 allows an Arduino board to connect to the Internet. It is based on the Wiznet W5100 ethernet chip providing a network (IP) stack capable of both TCP and UDP. The Arduino Ethernet Shield 2 supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which connect to the internet using the shield.
The ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top..
The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Duemilanove and Mega (using the Ethernet library coming in Arduino 0019). An SD card library is not yet included in the standard Arduino distribution, but the sdfatlib by Bill Greiman works well. See this tutorial from Adafruit Industries for instructions (thanks Limor!).
The latest revision of the shield also includes a reset controller, to ensure that the W5100 Ethernet module is properly reset on power-up. Previous revisions of the shield were not compatible with the Mega and need to be manually reset after power-up. The original revision of the shield contained a full-size SD card slot; this is not supported.
Arduino communicates with both the W5100 and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Duemilanove and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5100 and pin 4 for the SD card. These pins cannot be used for general i/o. On the Mega, the hardware SS pin, 53, is not used to select either the W5100 or the SD card, but it must be kept as an output or the SPI interface won’t work.
Note that because the W5100 and SD card share the SPI bus, only one can be active at a time. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. If you’re not using one of the peripherals in your program, however, you’ll need to explicitly deselect it. To do this with the SD card, set pin 4 as an output and write a high to it. For the W5100, set digital pin 10 as a high output.
The shield provides a standard RJ45 ethernet jack.
The reset button on the shield resets both the W5100 and the Arduino board.

it's tetris, in an altoids tin!
inside is an Arduino chip on a custom pcb that connects it to this LCD ($1 from sparkfun, talks over SPI) and four buttons. rotation works properly, collision detection seems to work fine, etc.
the eagle files are on randomskk.net/projects/arduino_tetris while the code is on github.com/randomskk/arduino_tetris (note that it's designed to be compiled from a makefile but you can strip out the WProgram and main() function at the end to make it compile from the arduino IDE)
I made it for a friend's birthday present and he seems to really like it
Some kind person dropped off this complete kit at a thrift store. Back in the day, all of this would have cost someone a month or two's pay. Today, around 100USD.
To the benefactor, it had no value; a techno-antique that would never be used again. Well, I'll give it some tender care in my elder camera museum. Then my kids will drop off the whole mess at some thrift store when I'm gone. Circle of consumer product's life, eh?
Canon A-1 body, Speedlite 199A, 28mm f/3.5 silver-nose, 135mm f/2.5 (5, not 8), 50mm f/3.5 macro lens and extension ring, 50mm f/1.4 SSC, and a (damned) generic 2X converter. (not shown - going right back to the thrift store).
At long last, after way too much procrastination, I have finished setting up my home electronics workbench. I used to work on a tiny folding table in the middle of the room with about two feet by two feet of empty space, and my parts cabinets on the floor on the other side of the room. This is much better.
This PCB contains most of the inner workings of the Inspiron 11z laptop: CPU, chipset, memory slot. Same daughter card may be utilized on other Dell laptop models as well, providing an easy way to repackaging the same hardware in different enclosures.
It appears that the VRM for the processor is located on this card as well.

Pentax 31/1.8 Limited
今天拿到了朋友订的SMC Pentax-FA 1:1.8 31mm AL Limited，尽管Pentax已经更新了14、21、40、70四只数字定焦，但是三公主的美丽却并没有因此而光华不济，相反却在这个时候愈发得惹人爱怜。
全金属镜身、温润紧凑，铝制切削镜身便是三公主外在美丽的由来之一。秉承Pentax小即是美的特质，滤镜直径为58mm。虽然只有345g，由于镜身本身小巧，手感颇为札实。尤其是在习惯了普通橡胶制合焦环后，31mm的铝制切削合焦环可以给你带来不同的感受。
7组9片结构，其中包括一片高折射率低色散镜，一片超低色散镜片（ED），一片非球面玻璃镜片（AL）。光圈叶片也为唯美的9片，透过镜头的SMC看过去十分吸引人，套用一个对ZEISS 1.4/85 ZF的形容，“看上去好像整个人都会被吸进去”，虽然这只镜头的口径不大，但是SMC与9片光圈叶片所创造出的感觉仍然让人陶醉于这公主之美。
镜头在AF时感觉虽然不比拥有超声波马达的镜头，但是内置浮动系统对于近拍时的影像弯曲做出了有效的修正，手边Pentax机身只有一部K100D，就不用来误导大家对这只头的成像了，所以没有试镜片。
Part of my job is taking photos of out-of-date and/or broken professional audio and video equipment and try to sell it on eBay. Normally most of the photos I take are rather boring, but I liked how this circuit board looked and snapped a photo.

My local Walmart recently under went a slight remodel in adding new signage as well as a slight rearrangement in aisles for some departments. I figured I'd take some photos of all the new sights. Pictures of the old arrangements can be found in the same album.
