Thank you!! It's been a lot of fun to create and we've learned a ton from it. I'm really proud of the course, but as long as you're building your own launch controller you can't go wrong either way!I like the content on the website.
I'm thinking about it. I'm interested in the continuity wiring.
Here's my current controller. I had to use a bigger wire because the speaker wires didn't have enough current.
Finally something good came from quarantine. Built my dream launch controller and just published the video about it!!
Time to keep dreaming and figure out what to make next, what improvements would you make to it??

And I had the same realization about the continuity check a few years ago....it is NOT a simple complete the circuit and send amps to igniter..it is complete the circuit to light the buib/led and then short out buib/led so all current goes to igniter and ignites engine. As an Electrical Eng (E.E) I never bother to figure that how....so even E.E's mind was blown
I love all the decals & electrical signage. Plus we use a similar auto toggle like you have in the middle. I love the way it feels!Here's my current controller. I had to use a bigger wire because the speaker wires didn't have enough current.

YESSSSSSS DUDE welcome aboard!!!! Team homemade launch controller for the win!Grrr. I need a better launch controller and now you guys make me want to build my own.
Edit: Screw it. Bought the course. I’m taking the plunge!
I think the part that blew my mind was not the complexity, but the simplicity. And the fact that for the Estes controller, the bulb is the resistor, making it even more simple. When you think of the design specs (launch a rocket, provide continuity check, safety interlock), an Estes controller is pretty brilliant.Yeah the Estes stock igniters are not great. I use QuickDip now to give them some actual pyrogen.
I dunno, isn't that just like, parallel wiring with a controlled switch? It's not all that complicated.
Continuity check: Use a resistor and LED, current is limited because of the resistor
Actual firing: Switch or relay creates low-resistance path directly to the igniter
If you're using an on/off or momentary switch for the continuity check, then you're even bypassing it entirely. This is how mine works. There's no magic here, just two current paths, and the continuity check draws < 100mA (I hope yours does!) because of the resistor used for the LED.
I did not mean complicated,.. I men usually I think a switch completes a circuit and it never occurred to me,until someone wrote an article about building your own..that you are not completing a circuit when you hit launch...but you are shorting out a current limiting bulb or LED so all juice goes to igniter. Usually shorting out anything is not something that was review/talk about in school during my course of study. So it blew my mind also.Yeah the Estes stock igniters are not great. I use QuickDip now to give them some actual pyrogen.

What did you use for the case/box?Here's my current controller. I had to use a bigger wire because the speaker wires didn't have enough current.

Nice work Kevin...…….
I built my own 4 pad high Power controller as well. Such a great deal of satisfaction building and using your own controller !!View attachment 426417View attachment 426418

Since you mention 2 buttons for 2 kids.... a number of designs used 2 buttons instead of safety key...buttons space far apart. I believe a commercial launch controller uses this approach.
Ah, too bad.All yours for the incredible price of $19...

The Amazon package is awesome.Hopefully it's a little more tidy than mine, which is quite a maze of wires! The amazon prime packaging foam in there is keeping the lithium batteries separated from the wiring to prevent any accidental shorts.

Links in the description. Sorry couldn’t copy/past.What did you use for the case/box?
