  Enter e14's 2016 Costume Contest Here!   There are only a few holidays here in the US that I actually participate in, with Halloween being my favorite by far. Many of you reading this might remember my two projects from last year, Foginator2000 and Trick or Trivia. They were both fun projects to build, and I learned a lot over the two months it took to build them. This year Element14 has asked me to build another project for Halloween, specifically a costume. Over the past week I h ...
Introduction This blog post is about powering a new security camera (HAL-CAM 9001) using network cables. These could be cables already installed in an office or home environment, saving costs, or they could be new cables installed indoors or outdoors (using weather resistant cable).   This sub-project is part of the HAL-CAM 9001 project but it is generic enough to suit other scenarios too. It could be used to power a Raspberry Pi remotely for other tasks. Other single board computers (SBCs ...
A recent project was delivered to me with a problem with its LCD screen. In the process of testing it I wanted to generate a composite video signal. After looking at some ideas involving Arduino and resistor dividers I came across some examples of raspberry Pi testcards, specifically RPI - ATV   I had an original Pi model B which has an RCA socket with composite out so that was ideal for my task. To get the testcard to work I downloaded a suitable picture and added my text to it. I then ...
See Part 1 of the project here. See Part 2 of the project here.   I received the 3D printed parts. I used good'old Shapeways to handle that!.   However, I had to drill and tap the mount holes for the Pi. It all fit together perfectly.     In the effort of portability, I am using one of the Pi TFT touchscreens   I used 2.5mm caphead bolts for mounting all parts. They fit perfectly into the mount positions.   Next update should be the final product!   C ...
