Wanted to find a was to get folks do share all those little "thingies" we have laying around in our Range Boxes that help perform the mundane but necessary field tasks that make Launch Days go easier.
I'll start things off with something that I've been using a very long time to eliminate most of the "BAD" igniter misfire irritations. I always check Estes, Quest or whoevers igniters with this small 1.5v Pocket igniter tester.
The original was thrown together from excess stuff I had laying around the model shop. A small plastic project box from RS, spst toggle switch, 1.5v lamp and lamp holder, single AA battery holder, two small pieces of Bronze sheet, a tiny bit of scrap hookup wire and a few screws. After a year or so in use I removed the switch which was found to be unnecessary.
Recently I built a custom size smaller AAA powered fabricated styrene plastic version to reduce the size and weight. This one easily fits in any pocket.
I use these testers constantly. I feel one is almost an essential for clustered motor igniter preperation.
Lets see some of the other Gizmos out there
