Well, I am rather good at circuits, but probably not that good. My main talent is making them blow up. Do you know if there are other soundboards available elsewhere?
Also, we have 2 engineers for parents who are extremely good at this kinda thing, do you reckon they could help us? It could be our little project
HAHAHAH I know what you mean about blowing up circuits. Yes, asking your parents sounds like a great idea, I'm sure they have the knowledge and would love to work on a project like that with you! I might even ask my dad about a few things, Artorius and I are trying to read up on the topic but you can only learn so much from literature alone.
As for soundboards, there are many different kinds. Econo boards are the ones I mentioned, they're taken from the basic toys that have lights and sound (go for the Obi Wan hilt though, it is smaller so it has the smallest board of them all - makes it easier to squeeze it into a small stunt saber). Tough to say what the next step up is, sound boards can get pretty expensive. If I had to recommend something one step up as a dueling saber, converting a Force FX saber to single LED on your own is reasonable (you can get a Force FX saber new for around $100, or used for even less). After that, your best bet is getting one of the Ultrasabers with Obsidian sound - the prices go up even more sharply from there on!
