Adafruit’s Show and Tell is a must if you’re looking to get ideas on various projects. Ladyada hosts a Google+ Hangout each Saturday evening in which she invites makers to share their latest projects. This past Show and Tell I showcased the USB Tester and a glimpse of the OLED backpack being developed. Enjoy!
USB Tester OLED Backpack on the Breadboard
As we wait for the USB Tester OLED backpack PCBs, I have started to develop the software that will run on it. If you missed it, here is a 3D model of the PCB: http://www.mobilewill.us/2012/12/3d-model-of-usb-tester-oled-adapter.html. Below is a picture of the display working on a breadboard. I am using an Xbee on a Sparkfun explorer as a load for testing. I even tested it with a Raspberry Pi while it is booting. Pretty neat, I am really excited to get this completed. USB Tester OLED Display On the breadboard you will see the Adafruit 128×32 SPI OLED display, INA219B DC High side current sensor (I2C), and a Arduino Leonardo. Currently the OLED display is using the default library that is bit banged SPI …
Raspberry Pi and eXtplorer
Over the last few months as I have been working with the Raspberry Pi, I have been using eXtplorer as a file manager and text editor. It is PHP and runs from the RPi’s web server. This is a great way to write code on the RPi from your desktop or from any web browser. I figured that I should share it since it is such a great tool. It should almost come with Rasbian. You can find it here: http://extplorer.net/ Here are some pictures of it running on the RPi: eXtplorer Login Screen eXtplorer File Manager Some of the great features are listed below (from their site). This is a must needed tool for working on the Raspberry Pi! I can’t …
SparkFun’s Engineering Roundtable: Domino Logic Gates
After a much needed winter break, I was able to catch-up and read some articles today. I’d like to share this video from SparkFun, of an easy way to learn logic gates using dominoes.
