After damaging the GPIO port on our raspberry pi while designing a new solar monitoring system we decided that it might be a good idea to build a buffer/level translator to protect the GPIO pins from over voltage and ESD spikes. The board would need to protect all of the data pins we normally use

Looking at the Raspberry Pi Cobbler in Adafuit’s wonderful collection of RPi accessories, I decided that it would be a much better method of connecting the the RPi GPIO to a breadboard than an old IDE cable with wires stuck in the end. I didn’t think I could justify paying $8 plus shipping to the

If your Raspberry Pi is purposed to do a task that normally does not require a monitor, mouse and keyboard (or any human interaction for that matter), sometimes it is useful to access your Raspberry Pi’s operating system without having to connect a monitor, mouse and keyboard. Here’s how Step 1: Required Materials You will

The Raspberry Pi is an amazing device. Although not the most powerful mini computer out there, it bolsters a tremendous support community, tons of hardware add-ons and coding libraries to your heart’s desire. The Raspberry Pi also makes an affordable media player but so much more can be done with it. In this post, I’ll

Description. Designing and building a USB sound card is no longer a head ache because we have got the PCM 2702 integrated circuit from Texas Instruments. The PCM2702 is an integrated 16 bit digital to analog converter that has two digital to analog output channels. The integrated interface controller of PCM2702 is compliant to the
When I got my Raspberry I’ve decided to develop an algorithm of real time lane and vehicle detection. I got it done. Now it’s time to put the Raspberry Pi on my car’s dashboard. However, I would not like to leave it fixed on the dashboard forever. I had a few lego bricks left over

Although the Internet of Things is relatively new, controlling devices remotely is as old as sin; devices have been using IR remotes for ages. There is a lot of untapped potential from the infrared devices sitting in your home. Besides the raspberry pi, you can get all of the materials for this project at your
