Hacking a bathroom weighscale for cloud connectivity

Posted on by One comment

Hardware hacker Darrel Tan has a great write-up about his experience with hacking a Chinese-made bathroom scale for cloud connectivity using a Raspberry Pi. His bathroom weighscale has a separate display part that receves the weight measurements from the scale through an infrared link. Darrel hooked up an 38kHz IR receiver to the logic analyzer and placed it near the scale as he was standing on it, so that he could decode the IR bursts. He found that the device used pulse distance coding to encode the data with ~75ms spacing between the consecutive bursts. With further analysis, he was able to figure

Another Raspberry Pi camera

Posted on by Leave a comment

Check out this Raspberry Pi powered compact camera that uses PiJuice, an all in one battery module, to power the device. I’m so excited about this new project! A truly compact and portable Raspberry Pi Camera and it’s easy as anything to build! I first thought about building a Raspberry Pi Camera after seeing theSnapPiCam instructable guide. This is a clever little project, which uses a LiPo battery to power a Raspberry Pi model A. But it got me thinking could I do something even more compact which is even simpler to build? The real challenge is powering this little baby.

Open-source ground penetrating RADAR

Posted on by One comment

Open ground penetrating RADAR is an ongoing open-source project initiated by Glenn Powers as his entry for the 2015 Hackaday Prize. The aim is to make a Raspberry Pi powered RADAR system to look into the Earth for less than $500. Commercial ground penetrating radar systems cost thousands of dollars. This project aims to create an open hardware alternative for about $500, using a Raspberry Pi with PiMSO to save data for later analysis and send instantaneous results to a web browser on a tablet or smartphone. A Baofeng VHF/UHF radio is used a signal generator, which transmits via a Transmit/Recieve switch

Raspberry Pi smartphone with 2G support

Posted on by Leave a comment

Tyler Spadgenske’s entry to 2015 Hack-A-Day Prize contest is tyfone, a DIY smartphone with 2G support using the Raspberry Pi, a 3.5in touchscreen display, and an Adafruit Fona module. The Raspberry Pi handles all the processing, and connects everything together. The TFT talks to the Raspberry Pi over SPI, and the FONA talks to it over UART. Everything is powered with a 1200mah battery connected to the FONA.The FONA has a charging circuit perfect for use with the phone. Since the battery is only 3.7v, a power boost is used to boost the voltage to 5v for the Raspberry Pi and
