Taught an Eggtimer Proton altimeter how to multi-task... I needed a down and dirty launch control system for the grandkids tomorrow and the Proton fit the bill.
First, and most important... the selection of a watertight container from Target... about $2.50. Then, the location of the 6 wire outlets were marked, and punched before drilling to prevent the bit from drifting (because the kids will only be launching one rocket at a time tomorrow, I only drilled 1 location);
did I forget to mention that the Proton, as a controller, can launch 6 rockets simultaneously,
now that's a grandchild's dream.
After that, the output wire was installed, the battery (in its anti-static bag) was placed in the bottom of the container, and the Proton was placed on top of the anti-static bag and connected to the battery.
Then, the setup was tested with a Christmas tree bulb (you use the Proton's WiFi interface test screen to launch the rockets, with a 5 second countdown on the phone's screen). The last two photographs show the closed container and the wiring for the launch pad (the JST adapter allows this setup to be substituted for the traditional large lead-acid battery powered system.
This setup does have two limitations that you need to be aware of,
each channel is limited to 10 amps and the total draw of all 6 channels is limited to 30 amps. For Estes rockets, though,
5 amps per channel for a drag race should be plenty.
I guess the only thing left to find out tomorrow is what the ground distance of the WiFi signal is.
