10 steps to making Shrinky Circuits

Shrinky Circuit is a way to rapidly prototype circuit boards without the conventional PCB /chemical etching procedure involved. (Optional) Color Color the Shrinky Dinks with colored pencil. Color on a single side should be enough if you are using the translucent shrinky dinks. Color both sides if...By: dorisleeContinue Reading »

Recycled Spotlight for Camping (12V DC)

Not too long ago, I bought a cordless drill from Goodwill and morphed it with half a set of jumper cables in order to have a mobile drill at camp (see it here!). That project turned out really well and left me with the remaining half set of jumper cables, which aren't good for much by themselves.Luc...By: FlatCatRussellandtheTennesseeTwoContinue Reading »


[Harrison Krix's] Marriott Chariot

Atlanta™s Mini Maker Faire had plenty of booths to keep visitors busy, but the largest spectacle by far was the racetrack smack-dab in the middle, and you™d be hard pressed to find a more eye-catching contender than [Harrison Krix's] vehicle: the Marriott Chariot.

If [Krix's] name looks familiar, that™s because he™s the master artisan behind Volpin Props, and is responsible for such favorites as the Futurama Holophonor replica and the Daft Punk helmet. (Actually, he made the other one, too).

The Chariot is yet another competitor in the Power Racing Series, an event that keeps popping ¦ Read the rest



Using Kinect To Play Super Mario Bros 3 On NES Ensures Quick Death

Why do only the new game consoles get all the cool peripherals? Being a man of action, [Paul] set out to change that. He had a Kinect V2 and an original Nintendo and thought it would be fun to get the two to work together.

Thinking it would be easiest to emulate a standard controller, [Paul] surfed the ˜net a bit until he found an excellent article that explained how the NES controller works. It turns out that besides the buttons, there™s only one shift register chip and some pull up resistors in the controller. Instead of soldering leads ¦ Read the rest



Capacitive Garage Door Opener Hides Behind Your Dash

[Pyrow] wanted to upgrade his garage door opener remote. It worked just fine, but changing those tiny batteries out can be an inconvenience. Plus, the remote control was taking up valuable storage space and would always rattle around while driving. [Pyrow] decided to make use of an Omron E2K-F10MC2 capacitive touch sensor to fix these issues.

[Pyrow's] circuit still makes use of the original remote control. He just added some of his own components to get it to do what he wanted. The circuit is powered by the car™s battery, so it never needs a battery replacement. The circuit ¦ Read the rest

Use a Cheap PIN Diode as a Geiger Counter

After the Fukushima nuclear power plant disaster, radiation measurement became newly relevant for a lot of people. Geiger-Müller tubes, previously a curiosity, became simultaneously important and scarce.

Opengeiger.de (English-language version here) has complete instructions for making a Geiger counter without a Geiger-Müller tube. Instead, this counter uses a PIN photodiode and some carefully chosen operational amplifiers. The total cost of such a device is significantly cheaper than the alternative: under $1 for the diode and around $5 for the rest. And since the PIN photodiode in question is used in many other devices, it™s not a niche ¦ Read the rest



An SDK for the ESP8266 WiFi Chip

The ESP8266 is a chip that turned a lot of heads recently, stuffing a WiFi radio, TCP/IP stack, and all the required bits to get a microcontroller on the Internet into a tiny, $5 module. It™s an interesting chip, not only because it™s a UART to WiFi module, allowing nearly anything to get on the Internet for $5, but because there™s a user-programmable microcontroller in this board. If only we had an SDK or a few libraries¦

The ESP8266 SDK is finally here. A complete SDK for the ESP8266 was just posted to the Expressif forums, along with a ¦ Read the rest



A Compact Underwater Vehicle: The Nanoseeker

The Nanoseeker is a compact underwater vehicle in a torpedo-like form factor. [John] designed the Nanoseeker as completely enclosed vehicle: both the thruster and the control fins are all housed within the diameter of the tube. The thruster is ducted with vents on the sides and control fins integrated into the back of the duct assembly.

[John] designed a compact PCB to drive the vehicle, which includes an STM32F4 alongside several sensors. An MPU-9150 provides IMU functionality and two dual motor driver ICs from TI control the throttle and the control fins. [John] also added a Bluetooth radio for remote ¦ Read the rest

STEAM Carnival Hacker Preview Day

Last week we wrote about the guys over at TwoBitCircus and their upcoming STEAM Carnival. This Thursday we managed to make it down to the Hacker Preview day where they showed us all the toys and games that will be exhibited over the weekend.

The preview day went pretty well until the evening, when unexpected power problems occurred and the site lost power for a little while. But this is why you have a preview day right? Organizer [Brent Bushnell] even commented that he should have put a BETA badge on the ticket. Thankfully the outage coincided with the food ¦ Read the rest



Using Excel to Watch Movies at Work

The Excel subreddit exploded earlier this week when redditor [AyrA_ch] shared his custom spreadsheet that allowed him to play video files on a locked-down work computer. How locked down? With no access to Windows Media Player and IE7 as the only browser (all plugins disabled, no HTML5), Excel became the unlikely hero to cure a 3-hour boredom stint.

Behind the cascade of rectangles and in the land of the Excel macro, [AyrA_ch] took advantage of the program™s VBA (Visual Basic for Applications) functions to circumvent the computer™s restrictions. Although VBA typically serves the more-complex-than-usual macro, it can also invoke some ¦ Read the rest



FlowPaw, the Bear Paw of Electronics Education

If the astonishing success of littleBits is any indication, there™s a huge market for ˜intro to electronics™ products that are much more capable than the classic Radio Shack ˜springs and components stuck to cardboard™ kits or even the very successful littleBits. FlowPaw is the latest entry in this space, combining the sensor module paradigm of littleBits with a largish microcontroller, digital and analog pins, and a great programming interface.

The big innovation in the FlowPaw is the FlowStone programming language. It™s a graphical programming language that allows young creators to connect blocks, modules, and functions together with virtual ¦ Read the rest
