Find the Item Contest

at 11:34 pm. Filed under Contests


Something a bit different this week. As you have probably seen we offer many free technical magazines that can be subscribed to by answering a few questions. The contest this week will be a hunt for the matching magazine.

The knife we are giving away this week will help you void warranties like no ones business when you need to crack the next hack open. If you are under age we will have to find something a bit more age appropriate as a prize.
This contest will run for one week (May 31 – June 5, 2008) . Ending time is based on central standard time. To enter, identify the magazine that matches the picture above. You can see the magazines here (catagories in are in the right column) Please do not give the answer in the comments.


Send an email to contest @ hackedgadgets.com with "Find the Item Contest" as the subject, and the message body consisting of:

  • The identify of the magazine that matches the above picture.

The winner will be chosen at random from all of the correct entries.


Added June 14, 2008 

The item to guess was a this magazine

The winner is Robert Y.

Thanks to all who entered.

Robot Power Plant

at 11:22 am. Filed under Complex Hacks, Electronic Hacks

This Robot Power Plant project by Ken Gracey over at Parallax shows how we can get away from using huge batteries for power hungry mobile projects. There are pictures of his second build style after the jump. 

"Project Purpose: 

To develop an outdoor robot power system which can deliver many more amp-hours of energy than batteries, using a gas engine and a modified automobile alternator. The initial purpose was not to build a robot, but to prototype a Hybrid Power Plant that I could use on an over-the-snow robot. A battery would merely support surges in current demand, like a big capacitor. It wouldn’t be there to provide power for anything more than half of a minute. This could lighten my load and extend operating time, particularly for a GPS autonomous robotic project.
After building the Hybrid Power Plant and running some tests on it with real loads I decided to put some motors on it and test it out on an R/C robot requiring much more current. This additional step turned out to be a big eye-opener, and gave me another purpose to the project – to test the system on a robot.  
Mechanical Design:
Coupling an alternator to a small gas engine requires that the shafts be perfectly aligned. Small "spider couplings" provide for up to 1 degree of angular misalignment, and 0.01" of horizontal offset. To align the engine and alternator I decided to make this a machining project (I had tried other ways before, and failed!). Using belts and pulleys would be out of the question due to the introduction of more moving parts, increased system slop and noise, and danger of moving parts.
The Hybrid Power Plant would was built by mounting the engine and alternator on their own plates, using a 3/4" aluminum rod as an additional alignment (and to double as handles). Although the alternator had two mounting holes, I opted not to use these since they were offset at different z-axis places. Instead, I machined the front of the alternator flat and drilled/tapped four holes in known locations. These holes allowed me to attach it to its mounting plate and perfectly identify the center shaft. The Honda mini 4-stroke engine (GX35) really needed a clutch – the power curve is way up in the RPMs and it generates little torque until 3,500 RPM. Staton-Inc makes a $60 clutch that has perfect mounting holes, enabling it to be mounted to a plate. I also attached the back and bottom of the engine to four more mounting locations on the base plate. The thought was that by mounting the engine to some sizeable chunks of aluminum I would smooth out vibration by closely coupling it to a mass.

Camera Flash Stun Gun

With just a few tools and a disposable camera you can build an inexpensive stun gun. In the video the wires are simply twisted but you should use a bit of solder to hold the wires securely.

Lego Autopilot

at 10:10 am. Filed under Complex Hacks, Cool Gadgets, Electronic Hacks, Toy Hacks, What Were They Thinking

With the Lego NXT being such a versatile platform for building and maintaining projects, I figured I needed to mention this crazy design. Chris Anderson over at diydrones.com built a small RC plane that he transformed into a UAV with a Lego NXT controller and some Robot C code. Any follower of the Lego Mindstorm Series or anyone currently competing in or interested in FIRST robotics will really want to read this!

"By creating a UAV with Lego parts and built in part by kids, we haven’t just created a "minimum UAV", we’ve created a reductio ad absurdum one. If children can make UAVs out of toys, the genie is out of the bottle. Clear use guidelines (such as staying below 400 feet and away from tall buildings) would be welcome, but blanket bans or requirements for explicit FAA approval for each launch will be too hard to enforce. The day when there was a limited "UAV industry" that could be regulated are gone.)"

DSLR Camera old Flash Adapter

at 5:14 am. Filed under Electronic Hacks


You can build this DSLR Camera old Flash Adapter for a few dollars and still use your old trusty camera flashes on your new gear. Looks like a nice simple and robust circuit.

"This instructable shows you how to make a really easy and simple circuit, that protects your new camera from high trigger voltages in old flashes. It is completely safe and will not damage the cameras circuits! It is better than those slave adapters that "look" for a flash, and then quickly activate the flash, since those adapters can be set off by other cameras. If you’re at a party, that can be quite annoying.

what you need:

– general soldering equiptment
– a sense of electronics
– an Optocoupler with triac output (i.e. MOC3062)
– 2 capacitors ( 10 µF )
– 3 resistors ( 500, 1M, 30…80 ohms)
– a casing (optional, I got mine on ebay)
– a battery"

Matthieu Deru and Simon Bergweiler from the German Research Center have put together an impressive hack that allows you to Fly in Google Earth using the Wii Balance Board

"After hours of testing and C# coding, you can now use your Wii Balance Board as a new input device."
