Been working on a few small projects and amongst them I've ended up designing, or redesigning some components that I think might be of interest for others, so over the next couple of weeks I'm going to get put some of these up on my, long neglected, Tindie store. In the above video I'm doing a show and tell of some new pull pin switch assemblies which can be used as rocketry arming switches but also can be of use for payload drop mechanisms or other pull pin applications.
I've also remade a version of my rocketry screw switches (although these are useful for any system that needs rugged violence proof power switching.. combat robots etc) I used to make these CNC routing them in my lair but that took a lot of time and I never got around to doing it so re-spinning the design means I can get the PCB fabricated by OSHpark. This means I should be able to produce stock quicker with less hassle for me, I plan to sell these in packs of 2 for $7.95, roughly £6.50.
Finally, I've also revisited my polarity protector board. These little boards only allow power through if they are connected the right way and therefore protect attached projects from reversed polarity. They draw a tiny amount of power (I don't even have anything capable of accurately measuring such small draw!) and can handle up to 20V input up to a continuous 4.3A. They are tiny and can be soldered into a wiring loom and covered in some heatshrink, or you can use them with pin headers, you could even attach the output to a breadboard. I'll put more details up on the Tindie listing when I get some stock built!
