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.
Presented at the 2013 KAPiFrance conference. Custom build controller box from ABS plastic to fit various electronic components and power source. This is my second ABS controller and after almost 10 years with the original box. It was time to build a smaller, lighter and sleeker box just for this event.
The weight & size for the first box is: 2.4 Kg @ 3580.5 cm3 and the new box is: 1.3 Kg @ 1677.5 cm3.

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.
Test of the TXT Controller for making short pulses. This is not going very well at all. The specified pulse widths and times are incorrect. The Robo software always uses a PWM cycle with a minimum time of 4.78 msec. You can specify a pulse width with a resolution of 512 units. But he doesn't do it that accurately. The minimum value should be 3, even better 4 units. Otherwise, you will not get any pulses at all, or you will get them very irregularly. You need to increase more than 1 unit to sometimes measure an increase. At 4 units the measured pulse time is 353 usec. At 16/512 this is only 406 usec.
Same story for the delay timer. It is not correct either. The requested 10 msec is about 15 msec and is not even stable. For short output times, the TXT Controller is not suitable at all! I normally use FPGA hardware and there you have times up to 10 nsec. I wasn't familiar with such bad times as those of the TXT Controller.
The analog signal is also very bad, especially the falling edge. You also have to place a fairly large load on the output, here this is 220 ohms. Without load on the output, you cannot obtain PWM pulses. The measuring signals contain a voltage divider to have a maximum voltage of 4V. The trigger value is set to 2V or 50% of the range.

This is going to be a KAP control system. It's based on the transmitter module of a 2.4GHz R/C system from Hobbyking (HK-T6A) but replaces the main board with an Arduino. The user interface utilizes a thumb joystick with integral button for aiming and shooting. It also has a ring LED to indicate pan and tilt settings. Several shooting modes will be selectable via a rotary encoder in the center of the LED ring. And, finally, there will be a bluetooth module to permit setup via a smartphone.
Most of the components were sourced from Sparkfun.com
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.

We spent another magnificent afternoon at Pataphysical Studios this Saturday, making art together … and playing at the edges of time.
Our visitors this week were Jim Neidhardt (now Dr. Neidhardt) and his lovely wife Denise (Dr. Now?), longtime friends of Drs. Rindbrain, Skidz and the Queen of the Desert. Jim showed us the ‘hypno-disks’ he is working on to create experiences like this surreal Duchamp film, Anemic Cinema: youtu.be/AsnhBUp7xxM?t=24s
We had a great conversation and I knew they were like-minded folks when Dr. Neidhardt and I both exclaimed at the same time the same exact phrase: “Life IS Change!”. Jim is interested in contributing to our madcap art adventure, so stay tuned. Learn more about his work at: neidhardtstudio.com/
Throughout the day, we brainstormed more ideas for our new Time Machine, while working on sundry maker art projects:
• Dr. Rindbrain and Canard put the finishing touches on their music box
• Drs. Figurine and Heatshrink prepared to assemble a theremin together
• Dr. Fabio drew a first sketch of what a time controller might look like
• Dr. Igor and Heatshrink both gave Dr. Figurine nice gifts for her birthday
• Dr. Tout de Suite considered lighting up her goggles, chose to paint instead
• Dr. Zboon discussed time travel and made a birthday card for his friend Ernesto
• Dr. Canard created a colorful zen map, inviting other doctors to art it up
• Dr. Rindbrain added more rainbow-colored lights to the Time Machine framework
It was great to stretch out to the edges of time and back again in the company of my friends.
Fire in the hole!

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.

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.

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.
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.

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.
Details and video here:
400 ton (363 tonne) ultra-class mining dump truck with Diesel electric drivetrain, powered by a 20-cylinder MTU/Detroit Diesel 20V4000 with 3750 horsepower.
The truck runs on six 59/80R63 tires with a diameter of 4 meters.
The hauler belongs to the fleet of Western Australia based Citic Pacific iron ore mine.
Trucks of this size class are intended to be loaded by rope shovels ore large hydraulic shovels like the Caterpillar 6090 FS.
Terex Unit Rig mining trucks are nowadays part of Caterpillar's product range where this model is still available as the 798.
My model in 1/28.5 scale is fully remote controlled, using a Sbrick controlled via bluetooth and the Brick Controller 2 app. The following functions are realized:
- Planetary rear axle driven by one Power Functions XL motor
- Front wheel steering by a CaDa micromotor
- Tipping body using a Power Functions L motor
- Front and rear lights, using five pairs of Power Functions LEDs
Furthermore, the model features the following mechanical functions:
- Suspended rigid rear axle
- Spring-loaded rigid front axle suspended on four longitudinal control arms and a Panhard rod
- Openable cabin doors
- Openable inspection hatch
- Deployable access ladder
The huge tires are non LEGO 140 mm crawler tires for 2.2 inch rims, mounted to LEGO Power Puller rims.
At launch, the Dreamcast included a number of controllers beyond the standard controller. One of these was the Dreamcast Fishing Controller. Designed for use in fishing games, it was a motion sensitive controller preceding the Wii Remote. The controller features a reel, buttons, and an analog stick. It is compatible with six Dreamcast fishing games. The Fishing Controller was, in part, an effort by Sega to bring the variety of controls available in arcades to home gamers. It is also notable as an example of blending traditional and motion controls in a unique controller intended for a very specific genre of games, rather than in a generalist controller like the Wii Remote.
Specialist remote area weed controllers from Wild Rivers Environmental Contractors, spraying Prickly Pear, while abseiling, at the Molonglo Gorge Forest Reserve.
Prickly Pears (Opuntioid Cacti) are Weeds of National Significance because of the serious impact they have on native vegetation and agriculture. At this site the Prickly Pear was starting to spread rapidly along the Gorge , so it was time to act and destroy the infestations.
Many thanks to the Wild Rivers crew and Chris Condon from ACT Parks and Conservation Service for their hard work controlling this environmental weed under difficult conditions.
