Homemade Launcher... 90V DC motors
Homemade Launcher... 90V DC motors + SCR controllers = Lots of FUN!
Keep in mind I built this out of various scrap I had laying around. All total I have about 100 bucks invested. A tad bit cheaper than the "REAL" launchers that they sell.
So what if you did NOT have some cool stuff laying around, but were willing to get resourceful I would say with some labor, maybe a couple favors - you could build one for around $300! My logic in saying this is: I bought a SPARE motor for mine off Ebay for 40 bucks DELIVERED. I see a guy selling refurbished KBIC controllers for 40 bucks a piece - so far that's $160. I bought the top wheels and tires off Ebay for $60 and the lower ones for 30 from Lowes. So add that 90 to the 160 and you get $250. That leaves you 50 bucks to gather some steel. The go - cart guys sell wheel/hub adapters although I made mine since I was trying to match a specific motor shaft as I had the motors laying around. They are easy enough to make any first year machinist could whip them up in no time. I bet a box of doughnuts and a visit to your local machine shop would yield some positive results.
I guess my point in all that is I keep seeing comments how "they'd be nice, but are too expensive!" Like a lot of things - if you want it cheap - you can do it - ya just gotta get a little creative ;-)
This is REV A - we'll use it a tad longer before we decide what improvements we need to make.
