* Award Winning GPS video injector Project *
Several weeks ago I entered a contest with this project. Today I got this in the email.
Thank you for participating in the Summer Fun with Arduino Challenge, and congrats on winning the CanaKit Raspberry Pi 3 B+ Starter Kit! I'm sure you're going to have lots of fun using it.
What can I say? I certainly will!
The purpose of this project was to make a DIY cheap Video Time inserter using an arduino uno. The idea and basic circuitry came from Piotr Smolarz.
I originally followed his instructions and got a working video inserter, but the antenna turned out to be too weak to find satellites. At that point, I simplified
the circuit by removing the transistor/led loop and removed all the switches except for the reset switch. Once I put an external antenna on it, it was able to find
11 satellites from my dining room and 4-6 satellites from my basement. I printed a 3D box and mounted it inside. Pictures can be downloaded below. The stl to print
the 3D box was located by Gregg Ruppel. It is a adjustable SCAD file and can be simply made to any set of dimensions. More information can be obtained by emailing me.
