 For this Cornell ECE 5760 Hand Tracking Pong project Hanting Lu and Kedari Elety have connected a camera to an FPGA, the image is down sampled so that it is only looking at a 40 X 30 image to determine how the players are moving. “The NTSC video signal from the camera is stored in the SDRAM at the rate of the TV Decoder Line clock (TD_CLK). Data
Most of us toss away our car and boat batteries when they no longer start our vehicle in the winter. Most of these batteries are now advertised as maintenance free lead acid, even though the electrolyte often still dries out. Youtube user Redicety12 shows us how you can bring them back to life by cracking the tops off the battery, dumping out all of the old electrolyte out, rinsing

I have tried something similar and was not successful since I was not able to line up the front and back of the PCB well enough for pads and vias to work. Rich uses a
