If you’ve ever wanted to try your hand at creating a Raspberry Pi-like board for yourself, you should check out [Jay Carlson’s] review of 10 different Linux-capable SoCs. Back in the 1960s, a computer was multiple refrigerator-sized boxes with thousands of interconnections and building one from scratch was only a dream for most people. Then ICs …
THINKING ABOUT CREATING A RASPBERRY PI REPLACEMENT? Continue Reading
It is hard to remember how expensive an electronic hobby used to be. It wasn’t long ago, for example, that a solderless breadboard was reasonably expensive and was likely to have some sort of baseboard. The nicer ones even had a power supply or some simple test instruments. While you can still buy that sort …
The new doppler board promises to meld the power of FPGA brains with microcontrollers and the accessibility of environments like Arduino. And the founder is so confident that could lead to new stuff, he’s making a “label” to help share your ideas. doppler is a small, 39EUR development board packing both an ARM microcontroller and an FPGA. It could …

In this sample, we will connect a Tri-color LED to Raspberry Pi 2. The LED will blink changing colors from Red, Blue, Green. In this sample, we will connect a Tri-color LED to Raspberry Pi 2. The LED will blink changing colors from Red, Blue, Green. This is a headed sample, so please ensure that …
I sold out more quick than expected. China is producing 100 new ones for me. I expect to increase stock around Christmas. Thanks for your understanding! This AEMLION is a 0.8×0.6 inch (20x15mm) PCB with the AEM10941 Solar Harvesting IC from E-peas. It efficiently converts solar energy into Li-ion battery charge, it even works with …
Story In this sample, we’ll connect an 8-bit serial-in, parallel-out shift register to your Raspberry Pi 2 and create a simple app that uses the shift register to control eight LEDs. This is a headed sample, so please ensure that your device is in headed mode by running this command: setbootoption.exe headed (changing the headed/headless …
Introduction In this sample, we will connect an RGB Controllable LED to a Raspberry Pi 2 and vary the intensity level of each color using a technique called Pulse Width Modulation (PWM). The ability to control the level of intensity of each of the three colors on the LED will allow us to make an …
The aim of this project is automatically checking emails and showing the presence of new messages with different LED colors corresponding to different Gmail labels. The final product is a USB powered, WiFi connected, 3d printed small box with beautifully colored LEDs. You can place it anywhere there is a WiFi signal, and check your mailbox …
Lights, Jumpers & the Resistance – Jumper wires are typically 22 gauge solid-core wires with insulation pre-stripped and readied for insertion in or out. Resistors resist the flow of electrical current, thereby controlling WHERE and HOW FAST it flows. [Thought experiment: If controlling water, using thin pipes would let less water through but would flow …

If you are using your Raspberry Pi with Breadboard, and you have lots of connections to make, then the Pi Cobbler from Adafruit is pretty neat. However, sometimes you only need to make a couple of connections and the Cobbler is overkill and a few Male to Female jumper leads will do just fine. The …
