I have been looking forward to providing simple electronic kits to
help people with homesteader projects. My first kit is going to be a
thermostat with 4-line text display. The idea is this thermostat can
be used with a device like a chest freezer to convert it over to a
refrigerator. This setup can reduce home refrigeration utilities by
20x. The same kit could also be used as a fermentation control device.
Using this kit would allow for a precision temperature controlled
environment which is important for things like tempeh, yogurt, cheese,
wine, etc... Here is the sketch of how things would connect. When
being used as a fermenter a heating element (20W light bulb) would
normally be used instead of the freezers compressor.
A modern device RBB arduino on a breadboard connected to an 4051 multiplexer with 8-10k pots. Output is made via Serial at 31250 BAUD for MIDI. Each pot corresponds to it's own controller (20-27) and has a value range of 0-127. A MIDI control byte is sent whenever a pot changes value for the corresponding controller. I will be adding two more 4051 multiplexers with a total of 16 pots and 8 push buttons.
Front view of the controller. The controller contain a DE1 FPGA board from Terasic. All timings and settings can be entred by a keyboard and readout by a LCD display. rotary encoders are used for fast adjusting of some parameters like amplitude of the waveform for the waterfigures. multiple waveform are predefined for optimal shapes on the figures. This waves are digital samples and are saved into a flash memory.
Here comes the branch: I'm most likely not going to bother with current control on the roomba and stick with odometry. I'm currently building a second controller board for the X-Y table steppers.
The XPC Controllers effortlessly connect to your CNTRL:R, Block, or OhmRGB through their 10 pin expansion ports with a single ribbon cable. The XPC series controllers allow you to add additional controls to your setup without having to add a bunch of extra gear and doesn’t take up additional USB ports.

My son loves playing video games, but that means many arguments over when it is time to turn them off and play with something else.

The ColecoVision came out in the age of the keypad and vertical configuration. Similar in design to the Intellivision or Atari 5200, the CV has an advantage over both of them: The buttons don’t totally suck. When you press a ColecoVision button, you know that you pressed it, unlike those mushy rubbery things that the other systems have. Like the 5200, the CV improves over the Intellivision by putting the control stick at the top of the controller and making it grippable. The CV also accepts game-specific overlays, but unlike other systems, the overlay goes underneath a plastic grid, so you’re able to know which number you’re hitting simply by touch. I’d say this controller is the least carpal tunnel inducing of the vertical keypad set. And best of all, the CV is compatible with Atari 2600 joysticks, so if the game you’re playing only needs one button, you can simply replace the controller with any number of more comfortable 2600 sticks or even a Genesis gamepad.

You can read about the TinyG Board Here:
www.synthetos.com/wiki/index.php?title=Projects:TinyG
The TinyG stack consists of:
Motion Control Node Hardware
Running an Atmel xmega chip.
Managing up to 4 local motors via on-board stepper controllers.
Node Controller Firmware
G code interpreter for coordinated motion control.
Low-level canonical motion control command and configuration set.
Networking to allow multiple nodes to be assembled into a large number of coordinated motion axes.
A Robust Packet Communications Protocol
Runs an RS-485 bus to drive a collection of nodes (2 wire, multi-master protocol).
Supports node-to-node addressable communications as well as unacknowledged and acknowledged broadcast transmissions.
Implements an easy-to-use ASCII protocol, as well as a more efficient binary form.
Easy to drive from Arduino (mega) serial monitor or by println() statements.
The Intellivision Hand Controller is one of the most reviled controllers in the world of video games. It’s almost as if it was designed by a group of parents who were concerned that their children spent too much time playing games, so they made a controller that would cause physical pain after roughly 30 minutes of play. There’s a sliding disc at the bottom, two buttons on each side, and a big number pad (With overlay support) in the middle. The problem is, I’ve never actually found a way to hold this controller that makes any sense. There’s nowhere to hold it so that you can use the disc comfortably. The buttons are rubbery and mushy and you never really know when you’ve pressed them, and they force you to hold the controller in an awkward way. For those who’ve never experienced what it’s like to use an Intellivision controller, imagine trying to use an oversized iPhone as a game controller, with the volume buttons as your main action buttons and the “Home” button as your control pad. And to top it off, the Intellivision controller is hardwired into the system, so you can’t get a third party controller that doesn’t suck. The Intellivision inspired a number of other controllers, including the Atari 5200 and the ColecoVision, but those controllers solved the problem by moving the disc to the top of the controller and replacing it with a joystick that could be gripped, making them far easier to use.
Don’t get me wrong, the Intellivision is an undisputed classic system, but if you want to play any of the games for it, you’re far better off picking up the latest Intellivision Lives! compilation and playing it on something like XBox Live Arcade or the DS. That way you won’t need wrist surgery next month.

The Maplins Robotarm kit came USB-only for computer control. The grandchildren weren't quite ready for that, so I built this simple panel using an old magnet/reedswitch keypad from the spares bin. Each key on the pad enables a double pole relay to supply the required polarity for motor direction. The centre-off slider switch selects between onboard batteries or 5 volt wallwart adaptor as power source. The on/off keys switch two blue bright flashing LEDs (just for added bling!) and the jaws' working light.
My friend's shoddy wireless router was not working, so we took it apart to find the problem. Since the casing was a mess, we decided to encase the router in something else, which turned out to be broken Dreamcast controller. Geeky fun!
Pacific Northwest National Laboratory developed the Smart Charger Controller (pictured) to manage peak demands in the electric grid as more electric vehicles hit the road. The Controller tells the car's battery when to start and stop re-charging based upon existing stress in the grid. The Controller's interface screen allows users to understand what the Controller is doing at any particular time during the charging cycle.

dd looking and often ridiculed, the Nintendo 64 controller is the only controller I know of that requires three hands to use. Players were required to undergo seven hours of surgery to attach a third arm, generally taken from Chinese prison camp inmates (Although later taken from chimpanzees after several tragic incidents where the transplanted arm retained some of the violent tendencies of its original owner). Unwillingness to submit to body modification is often credited as the primary reason for Nintendo’s lack of commercial success against the Sony Playstation, although many players reported many non-game related benefits to their newly installed third arms.
Actually, I like the N64 controller. It’s comfortable, and as long as you pretty much ignore the mostly useless D-Pad and L button, there’s nothing really wrong with it.

We built a giant LED board, about 6.5x6.5 feet, with 900 LEDs using ping-pong balls as diffusers. It can play Conway's Game of Life, Pong, and Sketch mode that allows you to create a starting pattern for Life. We output board state information to a MIDI board that allows us to make music based on what is displayed. This gets interesting with Life, creating minimalist generative music.

Thanks to Evil Mad Scientists for their Peggy 2.0, upon which we based the circuit for our project.
Renamed the temperature controller over to YATC (pronounced yahtzee
like the evil dice game). Here the temperature controller is in all
it's glory. Pricing is $50 assembled and $40 as a kit. This can make
any freezer run as a refrigerator at 2x the performance of the best
Energy Star refrigerator. We also use it for fermentations of yogurt,
kimchi, kombucha, bread and tempeh. It can easily be used for beer and
wine too. This is a must have for any homesteader. All the design
files that went into making this are completely open including
schematics, source, and board layout. Includes all necessary plugs and
custom laser cut acrylic enclosure.
