An Arduino with a prototyping shield, an RJ45 connector for up to 7 temperature probes, and a SparkFun serial 4x20 LCD.
side view of soda / beer vending machine prototype. To be cut out of 3mm acrylic and actuated by an arduino.
The idea behind this is that most college students buy a mini-fridge freshman year and then sell it sophomore or junior year. This way they can turn their freshman mini-fridge into a senior beer vending machine!
With a rectangular hole cut in the front of the door and an acrylic tray for the delivery, this can convert any mini-fridge (or regular fridge!) into a party favorite. Two units would fit into the smallest of fridges, and a full size one might be able to support 8 or more!
Accelerometer logger with neopixel display indicating G's of acceleration along an axis. Parts from Sparkfun and Adafruit. Case bits from Pokono.
SparkFun GLCD 128x64 GLCD with serial backpack connected to an Arduino that I'm using as part of my OpenEnergyMonitor system. A Nintendo DS touchscreen provides touch control. Video of it in action here.

Pinch the two outer pins together, clamp to the ground wire, solder, slide the tubing up, and shrink.
A behind-the-scenes look at SparkFun HQ life as we attempt to navigate business during the COVID-19 pandemic
Sparkfun's pick and place robot, hard at work populating a PCB with components for our tour group.
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.
So I got the sparkfun LSM303 breakout board working last night. Trouble is the I2C bus needs not higher than 1.8v logic levels to work properly.
The level shifter is capable of doing this, but it needs a 1.8v supply to operate, hence the white wire tapping it off the breakout board.
(The two yellow wires are due to the library pinout of the arduino nano board being bad)

Level converter:

Useful library for reading data:
The middle pin is data/power, the other two are ground. In the non-parasitic model, I believe the right leg is power, and the left is ground.
Clamp the data wire to the middle pin with the hemostats, solder, slide the tubing up and shrink it.
we've worked with our thread supplier & the thread that sparkfun sells will now be much less prone to fraying! We're now selling the internally 4-stranded thread shown in the next couple of photos.
High quality 16oz Libby pint glass emblazed with the SparkFun logo. Guaranteed to make beer taste better.
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. :)

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.
