Here’s an interesting concept. Lets make a kit to build your own super simple cell phone. Thats basically what a group at the MIT media lab is proposing with this prototype. Consisting of an SM5100b GSM module and a 1.8″ 160×128 pixel LCD screen on a very basic board holding some buttons, this thing is pretty bare bones. Barely any features aside from sending/receiving calls. It does have caller ID though. At$150, it isn’t really that competitive compared to the phones you’d get from your provider, but it is just a prototype.
We particularly like the laser cut flex areas for the buttons on the front.
[Overflo] recently tipped us about HackerspaceShop; his plan to help fund the Viennese and European hackerspaces by creating a marketplace for electronic kits. The idea is to not only sell kits, but to also create an easy way for others to sell their own kits through the platform, which is pretty awesome if you ask us.
Their kit they sent us to play with is a sun tracking flower developed by [daniel schatzmayr] in the metalab hackerspace. All and all, it’s a pretty awesome kit that’d be perfect for any geeky girlfriend, and of course, it’s arduino controlled. Whether or not that is a good or a bad thing is up to the hackaday trolls to decide, but it does have an FTDI header; something we’d personally like to see on a lot more of these electronic kits.
Currently there’s not to big a catalog on their site but hey, wickedlasers started out as a guy selling modified laser pointers and Hewett Packard started out as two guys selling a better function generator. It’s always awesome when a hacker uses their skills to become an entrepreneur, especially for a good cause.
Good luck [overflo]!
[Dino] got his hands on an FM transmitter “bug” kit via a friend, and thought it would make for an easy and fun Hack a Week project. The kit is simple two transistor half-wave FM transmitter, which the manufacturer suggests could be used to bug a room, hence the name. After poking a bit of fun at the instructions, [Dino] gets to work building the transmitter, wrapping things up in a little less than an hour.
Once he finished soldering everything together, he takes a few moments to test out the bug and to explain how various parts of the board work together in order to transmit the FM signal. He mentions that adding a dipole antenna would make it easy to extend the range of the transmitter, and briefly teases next week’s episode, where he plans on constructing a similar dual-stage transmitter.
This sort of FM circuit is one of the first few simple projects you would see in a beginner’s electronics class, so if you know anyone that is just starting to get their feet wet, be sure to pass this Hack a Week episode along.

Not every cool hack needs to involve microcontrollers, LEDs or other bling. We were initially drawn to the Bloxes display simply because we love a good multipurpose construction set, whether it be Lego, 80/20 aluminum, or in this case, a system of interlocking cubes formed from six identical pieces of corrugated cardboard, cut and scored in such a manner as to form a surprisingly sturdy little building block. They can become simple furniture, groovy Logan’s Run-style room decor, or the all-important kids’ forts…then later dismantled and made into something else.

NXP holds a lot of market share for their ARM based solutions as it is. That’s why we were a little surprised when we found a link on their website announcing that they were giving away free LPCXpresso development boards, based on their Cortex-M0 line.
Catches? Unfortunately there are a few to get the board shipped and running. In order to do so, you must…
- register with a corporate email address
…the promo is targeted at engineers
- use the crippled IDE supplied with the board
…due to hard to find (non-existent?) documentation for the integrated LPC-Link
- upload an original video of the physical destruction of a competing board to the NXP website
While killing your Arduino may not sound like the most fun, some qualified readers may be interested in moving up to 32-bits for a price that is hard to beat.
[Ammon Allgaier] built a tool that can break apart pin headers with a high level of precision. In the video after the break he demonstrates the built-in features. They include an adjustable stop to select the number of pins you’d like in each chopped segment. There’s also a small groove in the input side which the plastic frame of the header rides in. Just insert until it is touching the stop, and push down to break the header at the correct location. A couple of springs return the cutting tooth to its resting position, allowing you to make quick work of chipping up a 40-pin blank. This machine will become a nice companion for that automatic wire cutter.
This is great for single headers but we’ve long been on the lookout for a reliable way to snap off double pin headers. Far too often we make mistakes when trying to use two pair of pliers. If you know of a better way, please share your method in the comments.

Teaching kids to solder using kits is a fun time, but most of these beginner kits are a bit mundane. Not this one, it’s a solar-powered monster project. The components and their wiring connections are printed on a sheet of paper along with a background for that particular monster. The base of the paper is glued to a block of wood and at each solder junction there’s a copper nail. This way the kids can line up the components, check the picture to make sure the polarization is correct for each, then solder onto the large and stable nail head. As you can see in the video after the break, when the solar cell collects enough electricity the transistor triggers a motor to spin the monster.
But don’t get the idea that kits are only for kids. If you haven’t tried your hand with SMD soldering yet, this kit is for you.
