On the left, original, working, RC & cassette based retro Omnibot. His only upgrade is a new NiMH power pack. He has a broken hand which I still need to sort out.
On the right, enhanced semi-autonomous Omnibot with his new brain and power shoulders & elbows. I've installed a 6th toggle switch to enable separate switching of power supplies to the servo sequencers and UNO stack. Amongst other benefits, this reduces the likelihood of him making a dash for it half way through programming...!

(We have Kits, too.)
Assembled from a kit, for programming a wide range of "PIC" microcontrollers.
Designed to be connected to a Windows PC via a "real" RS232 connection, though there is an ICSP (In Circuit Serial Programming) header which increases its flexibility, allowing it to be used directly with a device such as the Microchip PicKit series.
Provides rudimentary test functions in the form of input switches and output LEDs

This is a binary clock that was built into a 3d-printed case created in Minecraft. It shows the current time in a binary coded decimal format.
The model was exported with the free tool Mineways and printed on a Zprinter 650 3d-printer, with a block size of 125mm^3 (so every block has an edge length of 5mm). After printing, LEDs were glued into the case after filing the openings a bit wider. Then, the LEDs were soldered to form a 4x4 LED matrix, and the matrix was connected to an Arduino board.
A technical description of the setup as well as downloads of the model and the code can be found here: postapocalypticresearchinstitute.wordpress.com/2012/07/18...

Frequently, while at the office or out of town, I find (to my dismay) that I need to access files on my desktop computer at home. The inevitable results are special trips and wasted time. While I could leave my desktop on indefinitely and access files remotely as, the inordinate amount of electricity that it consumes literally doubles my electric bill. With the help of an Arduino, I've solved the problem for good, for the cost of about 3 months of running my desktop all day.

I hacked a power switch into my programmer instead of the silly little jumper that I lost about 5 minutes after receiving the kit. The switch turns on/off power to the chip being programmed.
With it on, the programmer can be used as a low-current power supply to, say, a chip in a prototype board. Or with it off, the programmer can be used to reprogram a chip in a fully powered, production, environment.
The setup on my desk for testing and developing the firmware and Verilog for my FPGA-accelerated vision platform.
Pictured:
- my MT9V032 LVDS camera board
- a Xilinx Spartan-6 FPGA SP605 board.
As of this photo, I've successfully developed the code that allows the Spartan-6 to deserialize the MT9V032's 300+ Mbps LVDS data stream - I use the FPGA's SerDes blocks to perform the deserialization, rather than relying on an external deserializer chip (as suggested in the image sensor's data sheet).
That little green LED on the FMC-LPC board (should you actually be able to see it) indicates that the FPGA has successfully locked to the MT9V032's output. Remarkably, it worked on the first try (no doubt thanks to simulating everything beforehand! - some simulation waveforms are just barely visible on my monitor in the upper right).
Next step: actually sending the video data somewhere to confirm that the sensor is really truly working (good thing the SP605 has a DVI output..).

An Arduino microcontroller uses a CdS photocell and a set of LEDs to indicate the ambient light level. (Move your mouse over the picture to see explanatory notes.)
Just fooling around because I was bored. Maybe I'll think of a good use for this later.

My makeshift automated panorama rig. Mostly made from spare parts and junk.
[updated 2012.07.24] It seems this made it on hackaday: hackaday.com/2012/07/24/motorized-camera-rig-makes-panora... Greetings! I'll try to get some documentation together and post the code somewhere in the coming weeks.
Movement is handled by two servos at the top, mounted to some scrap wood using screws and wood glue. That mounts to the tripod via a 1/4-20 clawed T-bolt. The camera secures to a set of overpriced plastic servo pan/tilt plates.
The servos are controlled via an Arduino Nano (Atmel AVR 328p) powered by a 9v battery for the microcontroller(μc), and 4xAA batteries for the servos. The clear housing was saved from the trash, and holes for the wires and switch were cut by using a heat gun on an exacto knife. The case secures to the tripod using velcro and elastic. An IR receiver, mounted on top of the case, takes input from a small generic remote control(not pictured).
Several quick programs are accessible with only 2 key presses for the most commonly used angles. Manual angle input and adjustment are also available, as are startup delays and repeating functions. It can also be re-configured in the field, via the remote, and allows the changing of camera specs, such as horizontal and vertical field of view, h/v overlaps, servo speed and end stops. The μc is programed to, on it's own, determine the number of shots, and the best angles to shoot, in order to capture the requested area. There's also some rudimentary duplicate avoidance written in, which skips photographing areas that would significantly overlap with previous photos, such as in the polar regions.
There are plenty of problems with the version as shown. For starters, it doesn't center its rotation around the shutter, which causes parallax errors. The current servos aren't strong enough for anything heavier than a compact point-and-shoot. There's no shutter control yet. A third servo lead is tucked in back, and the code written, but at the moment, it's just synced with the camera's internal 10 second repeat auto timer. The code was quick and sloppy, but it does the job. I should probably clean it up and open source it at some point. So far, though, it has performed far better than I expected. Most issues could be resolved without much work, but at the moment, I'm just going to enjoy using it.
Except for the Marigot Bay panorama and the Marblehead harbor fireworks panorama(which were done by hand) most of the panoramas and stereographic "little planets" in this photostream were taken using this rig with a casio ex-g1 point-and-shoot.
You can check out some of the interactive and immersive 360º images it has produced using the viewer at fieldofview here , or just check out the rest of the photostream here.

Visitors to our family blog can launch a car from our closet for our toddler to play with. I built a simple gravity-powered car launcher that is controlled by the web site. Clicking "Launch Car Now!" on the web site results in a sound clip from the movie "Cars" playing in our living room, followed by a car shooting out from under the coat closet door. The website uses a bit of PHP to send an email to my wife's computer, which happens to sit in the living room next to the coat closet. I created a filter in Apple Mail to run an AppleScript when a correctly coded email comes through. The AppleScript pauses iTunes and raises the system volume of the computer before activating a small applet I wrote in the Processing language. The Processing applet plays a bit of Lightning McQueen (main character in "Cars") psyching himself up before a big race. The applet then sends an "l" to the serial port, where the car launcher's Basic Stamp II microcontroller is patiently waiting. The BSII opens the sliding garage door on the launcher exactly one bay. There are five bays, for five cars. I set up little tabs to interrupt an infrared beam as the edge of each opening is reached. Once a given bay is open, gravity pulls the toy car out and down the ramp. Momentum carries it under the closed closet door and across the floor to the excited toddler. After receiving each launch command (each clicked "Launch Car Now! from the web site), the launcher will release one car and then wait for another command, progressing until the door is completely open and all cars have been released. The launcher door will then close and wait to be reloaded. The PHP on the web server makes sure the "Launch Car Now!" link is only available during usual playtime hours and also limits the number of cars launched to five per day.
This is my simple circuit with preamp module inserted to display music on a VGA monitor like on an oscilloscope.

8 bit microcontroller with 20kByte of internal Flash-ROM, 256x8bit RAM, 8051-compatible
Size is about 7mm x 4mm
Microchip expanded its Arduino™ compatible chipKIT™ platform ecosystem to include a new Raspberry Pi® tool that it co-developed with partner element14—the chipKIT Pi Expansion Board. On the software side, volunteers from the chipKIT and Arduino communities collaborated with Microchip’s engineers to expand the free chipKIT Multi-Platform IDE (MPIDE), to allow users to create, compile and program Arduino sketch-based chipKIT applications within the Raspberry Pi operating system. The chipKIT MPIDE is open source and compatible with the Arduino programming language and development environment. Both of these tools are based on Microchip’s 32-bit PIC32 microcontrollers (MCUs) in prototyping-friendly, low pin count SPDIP packages, which was previously only available with 8-bit MCUs for the Arduino community. This enables all users—including hobbyists, academics, makers and professionals—to benefit from the PIC32’s high performance, memory and integrated peripherals while using the basic hobbyist prototyping equipment that is found in most home workshops.
