Fairly easy to make. When I got the Classic controller for the Nintendo Wii, I noticed how well-shaped the packaging was. So, I filled it up with melted chocolate, pretzels, cheerios, and then put it in the freezer overnight and I got myself a cute candybar!

U.S. Air Force combat controllers conduct fast-rope insertion training using a U.S. Navy HH-60H Seahawk helicopter assigned to Helicopter Sea Combat Squadron (HSC) 84 at Hurlburt Field, Fla., May 2, 2014, during Emerald Warrior 2014. Emerald Warrior is a U.S. Special Operations Command-sponsored two-week joint/combined tactical exercise designed to provide realistic military training in an urban setting.

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.

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.
Here's a project finished a couple months ago. I'm quite happy with how it turned out.
Built a simple wooden box and stained it white for a clean look while keeping most of the grain.
I used Seimitsu buttons, Crown 303 N joystick and Adafruit bluefruit-EZ key bluetooth controller chip.
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.
This low cost charger controller for under £20 gives better results than an expensive Morning Star £70 controller I had in my last van.
After checking levels and tightness of the connections at the battery and charge controller this week in March 2011, I noticed the pulsing equalization charge to the battery from the controller was 14.9 volts, I was a bit alarmed at such a high voltage at first, until I re-read the instruction manual, it stated that when the battery is fully charged and the ambient temperature is at zero or below, the controller will output nearly 15 volts in the equalisation mode for a short time before going into float mode of 13.8 volts. The equalisation mode will bring all cells in the battery bank up to the same charge level, so conditioning the battery. Seems to work as I have never had an Elecsol Carbon Fibre battery fail me in the last eleven years, the oldest battery being over ten years old, putting an old battery and new battery in parallel is supposed to be a no no, but it worked for me, and the charge controller seemed happy enough.
I am not sure just how happy my unregulated cheapo SMD 5050 LED lighting will be with a pulsating (PWM) line voltage/power, although if the sun is out I suppose I won’t be using the lights anyway.

Hi Pete,
The SMD 5050 leds I have are the two quid variety from China, they have the tiny MB6S bridge rectifier so the led assembly connections are not polarity conscious, and a selection of resistors mounted on the pcb rear, but no voltage stabilisers, so they are rated at 12 volts only. Reading the forums some members have suggested that they should work up to 13.5 volts with not too much detriment to their longevity.
On a fully charged battery and when the controller is in the equalisation mode, the PWM frequency is fast enough not to effect the performance of the leds , i.e. no flickering can be detected, the battery would smooth things out as you remark, but the voltage at the battery terminals is still reading nearly 15 volts, not too good for my cheapo Chinese SMD 5050 leds.
I noticed as the cvan voltmeter was indicating 15 volts (verified) while the ammeter monitoring the controller output power, was cycling very quickly between 0.3 amps to 1.5 amps, now I know the ammeter will lag, but it looks to me as if the PWM is pulsing the power and not the voltage. If we get the same sunny conditions and zero ambient temperature later I will put my scope on the controller output to see what is actually happening.
I think you will find the 12 volt G4 LED types that stand up to 30 volts are the ones that cost upwards of £8 each not the 30 bob ones that I have – I know I’m a cheapskate -
Does anyone else have the combination of Solar Panel and the Cheapo Chinese LEDs ? and could check the battery voltage on a fully charged battery when the sun comes up?

A breadboard test of a DC motor controller. It works by PWM (Pulse-Width Modulation), using a TLC3704 comparator chip to generate a variable mark/space ratio square wave. This is then fed to a HUF75337 power MOSFET. There's a 5k pot in a box to control it.
gotta love the korg radias... but you also gotta love the nes controllers with usb adapters and an NES emulator running Zelds II The Adventures of Link on the big screen with too many speakers!
The next challenge is to replicate the equipment shown here on the rear deck such as the controller and meter housing. The right-hand box could house a knifeswitch or main fuse, I'm not sure.

Wirering base
Hall magnet in place. This locks the movement of the wires in the handle. So no pulling the wires when the magnet is installed.
I soldered wires to the contact points for the 6 base buttons like this:

And managed to short out all of them and had to use a sharp knife point to break all the unwanted connections.
Another solution is to scrape of the paint from the traces leading to the connection points and solder the wire there. It retains the full use of the base buttons.
