What should I build with these parts?

[Jrockpsycho]

I have a bunch of RCA 40468a, UA741, and TL061. Any ideas? Thanks!

The 741 and TL061 could be used in a DOD 250, or even a Rat variant.

Looks like the 40468a is an n-channel mosfet, so maybe you could build a mosfet boost with it... most of these circuits are spec-ed for bs170 or 2n7000, but I'm not sure if the 40468a would drop right in, or if it would need tweaking to work. If it works, you could also build a box of rock or charlie brown, which are using several mosfets.

Isn't that 4068a a 4 legged Transistor?

The 40468a could also perhaps be used for clipping?

Hmm, what is the 4th leg? I see in a few sample schematics that the extra leg is grounded, but I don't find a lot of info about this component.

I believe it goes to ground so you need to get the pinout correct!
