If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.
The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.

- Mass SD card Image Writer
-
-
We've built a mass SD card writer using a Raspberry Pi 3 Model B, some USB hubs and SD card readers. This beast has enough ports to write 49 SD cards at once! At Core Electronics, sometimes logistics hang-ups mean that suppliers cannot meet our demand for pre-flashed SD cards. During these periods we have to pick up the slack by manually imaging blank SD cards we source ourselves. Of course, this is a super-tedious process, and ...

- Coffee Grinder With Arduino
-
-
Using a few bits and pieces, this ordinary coffee grinder now has two presets to run the motor for a programmable length of time. The idea being that the grinder running for a set amount of time will deliver a certain amount of coffee each button press meaning the beans can be stored unground, keeping them fresher for longer. I completed this project for a friend, Ian, who lives for coffee. Ian wanted the same functionality in h...
