Here’s my DIY launcher. I have the battery pack on order. I thought I might try a 9v battery but determined that it won’t ignite the starters. So why will 4x 1.5v batteries ignite but not one 9v battery? What is the comparison in amps?
I previously looked up resistance comparison and 9v has 10x more than AA but in my head, I was thinking that more is better. Doh. Good thing I’m not a rocket scientist.

All Electronics (www.allelectronics.com) is one place to get parts. eBay also has lots of options as well.Thanks for the information. You did a great job.
I would like to have a continuity light, a launch button and another switch that must be on in order to launch. I would like that switch to spring back to the off position after you release it. I like those launch buttons that have the cover that has to be lifted up.
Just wondering where people buy electronic parts these days? RIP Radio Shack.

Not if it's the diagram at 1:53 in the video, which just shows generic symbols for all the components. For each of them, there are about a 6.4 million (I counted) variations available. You'll need to get a whole lot more specific than that, if not actual part numbers than at the very least some reasonably detailed specs for each part.Someone in my club mentioned You Do It Electronics in Needham, MA.
If I went over with a diagram, I wonder if they would be able to grab the parts for me?

I was hoping I could go to an electronics store, tell them I want to build a 12 volt system and give them a description of each part in addition to the diagram.Not if it's the diagram at 1:53 in the video, which just shows generic symbols for all the components.

You can try, but in my opinion that is somewhat above and beyond what I would ever ask for in a store. Those folks are unlikely to have any idea about the behaviors and requirements of a launch controller. A few of the items they could guide you to (work box, soldering iron, solder) but not everything else.

If you're not familiar enough with electronics to at least be able to spec out those parts, I would suggest working from a more detailed plan that gives a detailed parts list.
Does Aerotech still sell their launch controller? (controller, not the Mantis launch pad) It is ideally set up to run from any number of power sources and is a good option for personal launches. I have one and just thought about switching the power connections from the alligator clips for a car battery to a set of Deans plugs so I can use a 3S 50C 6000mAh battery pack I have.
Not the same thing, unfortunately. IMHO.I was thinking about when I go to the Micro Center computer store. I give them a list, we discuss the brands and what the computer will be used for. Then we walk around the store with a basket, the sales consultabt helps me pick out what I need, and I'm off to build the computer.
There were a few discussions this week on launch controllers this week..do a search on the forum....the initial topic was on clustering and Estes PSII controller. It has been brought up numerous times this year...Thanks for the information. You did a great job.
