Adafruit Releases New TV-B-Gone Kit

August 17, 2009 by 54 Comments

Recently, our friends over at Adafruit released a new version of their popular TV-B-Gone kit. Built in cooperation with [Mitch Altman], the inventor of the TV-B-Gone, the new kit sports four high power IR LEDs, two wide beam and two narrow beam. The four LEDs give the new TV-B-Gone increased range, with a maximum distance of over 150ft. One of the most impressive features of the kit is the fact that the new TV-B-Gone is universal and can now work in Europe and Asia in addition to the US. Users are able to select which region they want to use during the build process by soldering a resistor into the board at their region’s corresponding spot as seen in the picture above. The new TV-B-Gone kit is now available in the Adafruit store for $19.95 plus shipping.

Adjustable Breadboard Supply

adafruit industries’ latest product is an adjustable breadboard power supply kit. We’ve seen breadboard supplies before, but like most of adafruit’s kits, this is the best design you’re going to encounter. It uses an MIC2941 voltage regulator instead of the more commonplace LM317. It has a very low dropout which means your output voltage can be much closer to the input voltage. Their example is using 3AAA or a Li-Ion battery for an output of 3.3V. Input can be through a barrel jack or terminal blocks. There is a selection switch for 3.3, 5, and adjustable voltage. Using the adjustment pot you can select an output voltage anywhere from 1.3V to within .5V of the 20V maximum input. The adjusted output voltage will remain the same even if you increase the input voltage. Like all of their kits, you can find schematics, assembly and usage instructions, on their project site.

SparkFun Open-sources Latest Kits

SparkFun has started to release some of their kits as open-source hardware. Projects such as ClockIt, a simple alarm clock, have their schematics, board designs, and source code released under the CC-by-sa license. Although most of their widgets and projects already had example code and schematics available, they are now using an open-source license. They are joining adafruit and EMSL and others in pushing OSH, but it is interesting to see an established company turn to this. Normally, startups do this to encourage early adoption.

Our friends over [adafruit] recently released the Sensor Pack 900, a collection of parts for anyone who is interested in using analog sensors with their projects. The pack includes 9 sensors. They range from simple thermistors and hall effect sensors to sharp distance sensors. Also included in the pack are 3 unidentified components that can be used to interface with the analog sensors in the pack. At only $30, the Sensor Pack 900 seems to offer a great set of introductory components for anyone prototyping a new device.

Business Cards At Maker Faire

[John Park] has managed to snag a couple interesting business cards at Maker Faire. The first is Adafruit’s laser cut Spirograph card. The other is a ATtiny2313 prototyping board from Evil Mad Science; it looks to be the same style as their well-known AVR target board. We’ve also heard rumors that [Jérôme Demers] has bunch of resistor bending cards.

Massive Etch A Sketch From TV Screen

[Jeri] put together an absolutely massive Etch A Sketch for The FatMan and Circuit Girl show. She had removed the DLP chip from an HD rear projection TV and decided to repurpose the 52inch screen. The movement mechanism uses pulleys from screen doors with nylon lines. The two sets of lines are fed in a criss cross pattern so that the parallel lines move in the same direction. The lines move tent poles in the x and y which controls the movements of the golf tee stylus. It’s driven by two high torque motors from $9 Harbor Freight 18V drills. They tried several different powders, but ended up using aluminum powder from an original Etch A Sketch because it sticks to everything. It will eventually be hooked up for IRC bot control once they get a large enough h-bridge.
