All the guts fit in a tin (altoid size). Neopixel assembly mounts on messenger bag. Arduino sketch only lights on LED at a time, runs for many hours on one charged eneloop (Sanyo) AAA battery.
If I remember right, this one is called Ohcraptheresalake. :)
Sparkfun had their autonomous vehicle competition on Wednesday, and I took an hour from work to check them out. I only got to see a few of the attempts, then took a tour of the company, and went back to work.
This new revision of the MP3 player shield retains the awesome MP3 decoding abilities of the last version but adds the storage functionality of the SD card shield. Now you can pull MP3 files from an microSD card and play them using only one shield, effectively turning any Arduino into a fully functional stand-alone MP3 player! The MP3 Shield still utilizes the VS1053B MP3 audio decoder IC to decode audio files. The VS1053 is also capable of decoding Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM and user-loadable Ogg Vorbis.
The VS1053 receives its input bitstream through a serial input bus (SPI). After the stream has been decoded by the IC, the audio is sent out to both a 3.5mm stereo headphone jack, as well as a 2-pin 0.1" pitch header.
Available soon!
I managed to fix the left-right mirroring of sparkfun's O-Clock on my cheap 'scope by tweaking the firmware.
I downloaded AvrStudio4,
the source &
the uploader.
In AvrStudio I set Configuration options|Custom Options
gcc: C:\WinAVR-20100110\bin\avr-gcc.exe
make: C:\WinAVR-20100110\utils\bin\make.exe
Then make the following source changes
In ClkConfig.h edit:
#define ds1307 1 // Sparkfun Hardware
#define pcf8563 0 // Dutchtronix Hardware
and, at the bottom, add:
#define INVERT_X 1
//#define INVERT_Y 1
In ClkRender.s, look for DACXYPos and DACYXPos subroutines. Both have two parts like this
#if INVERT
neg r22 ; map [X/Y] origin
#endif
In each subroutine, change the first occurrence to #if INVERT_X and the second to #if INVERT_Y (even though the comment may mention the other coordinate).
Build, then follow Firmware upgrading instructions.
See the set.

Speeds have plummeted in the building as more than a third of the company now works remote.

Traditionally, Hello World programs are used to illustrate how the process of coding works, as well as to ensure that a language or system is operating correctly. They are usually the first programs that new coders learn, because even those with little or no experience can execute Hello World both easily and correctly.

In a moment of downtime, AJ displays one of his more impressive finds from the Free Table - a spot in the SparkFun breakroom for employees to pass on former treasures.

The SparkFun lobby - normally a welcoming hub of friendly faces and pick-up orders. We look forward to the return of both! For now, the faces now work at home, and the orders are shipped direct to customers.
Adafruit GPS Data Logger Shield with a 12volt battery pack and Spark Fun LCD. Right now it logs every second to a SD card and displays location and time alternately every 2 seconds.
Next I'm going to add an accelerometer and log g-forces while driving around the track.
The diversity team, Collective Spark, has officially completed our transformation of the bicycle area, now known as the Spoke House! Another space completed by this team = BIG WU!! Our main goal, as a team, is to revamp common spaces around the building. We started with Planet Express; them moved to the Bridge area, and now the Spoke House.
Picked up a Tamron 11-16mm F/2.8 yesterday. Expect great things in the very near future ;)

Also quite blurred, but not bad for a cheap and very old 'scope. All I needed was a way to flip the image. Two options. I could create a circuit which would invert the voltage or I could change the frmware. A fair bit of googling later, and I hadn't found a hardware solution so I had to change the firmware.
