Power for your breadboards. It’s a USB connector, a 3.3V voltage regulator, and a few pins that plug into the rails of a breadboard.
“Have you seen those ‘Portable battery chargers for smartphones?’ Well the idea of the device is based on it , but the difference here is the internet part.” That’s a direct quote from this Indiegogo campaign. It’s funny because I don’t remember losing my damn mind recently. Wait. It’s $200. Yep. Yep. Definitely lost my mind there.
Putting the Internet on a USB stick not weird enough? Hair Highways. Yep, human hair. It’s just embedding human hair into resin, cutting everything up into plates, and assembling these plates into decorative objects. As a structural material, it’s probably only as strong as the resin itself, but with enough hair set in layers perpendicular to each other, it would be the same idea as fiberglass. Only made out of hair.
Tesla is building a $30,000 car and Harley is building an electric motorcycle. The marketing line for the bike will probably be something like, “living life on your own terms, 50 miles at a time”.
PixelClock? It’s a 64×64 array of red LEDs built to be a clock, and low-resolution display. It looks blindingly bright in the video, something that’s hard to do with red LEDs.
While we can’t condone the actual use of this device, [Husam]’s portable WiFi jammer is actually pretty cool. It uses a Raspberry Pi and an Aircrack-ng compatible dongle to spam the airwaves with deauth packets. The entire device is packaged in a neat box with an Arduino-controlled LCD and RGB LEDs. Check out an imgur gallery here.
You can pick up a wireless phone charger real cheap from any of the usual internet outlets, but try finding one that’s also a phone stand. [Malcolm] created his own. He used a Qi charger from DealExtreme and attached it to a 3D printed phone stand.
A while back, [John] noticed an old tube radio in an antique store. No, he didn’t replace the guts with a Raspberry Pi and an SD card full of MP3s. He just brought it back to working condition. After fixing the wiring (no ground cord on these old things), repairing the speaker cone, putting some new twine on the tuner and replacing the caps, [John] has himself a new old radio. Here’s a video of the complete refurbishment.
Here’s a Sega Master System (pretty much a Game Gear) running on an STM32 dev board. Also included are some ROMs for some classic games – Sonic the Hedgehog, Castle of Illusion, and The Lion King. If you have this STM Discovery board you can grab the emulator right here.
[Spencer] wanted a longer battery life in his iPhone, so he did what any engineering student would do: he put another battery in parallel.
Breadboarding something with an AVR or MAX232? Print out some of these stickers and make sure you get the pinouts right. Thanks, [Marius].
Since our ‘ol buddy [Caleb] left Hackaday for EE Times, he’s been very busy. One of his latest projects is doing Antique Electronics Autopsies. This time around it’s a 1953 Heathkit Grid Dip Meter. It’s a beautiful piece of engineering with Point to Point wiring and metal gears.
We love microcontroller breakout boards, and so does [Tim] apparently. He built a breadboard friendly breakout for the NXP LPC812. It’s an ARM Cortex M0+ with 16kb of Flash and 4kb of SRAM. The entire breakout board is smaller than the through-hole DIP LPC1114. When are we going to see these on Tindie, [Tim]? Here’s the Git with the board files. You can also pick up a board at OSH Park – $3.30 for a set of three.
What do you do when you have the perfect idea for a Kickstarter, but don’t have the funds for the perfect sales pitch? The obvious solution is to start an Indiegogo campaign to raise funds for your Kickstarter. Unfortunately, this campaign has already been successfully funded, so it’s already too late to get in on the ground floor. Relevant xkcd.
We’ve seen this DIY cell phone before but now it’s just about ready for production. [David] at the MIT Media Lab has been working on a bare-bones, ATMega & GSM module phone for a while now, and now you can grab the firmware and board files. Make your own cell phone!
Here comes Hanukkah, so drink your gin and tonica. Here’s a pedal powered menorahica so put on your yarmulke, it’s time to celebrate Hanukkah.
