Electrical Engineers Unite...or Multiplex!

[Impetus]

I'm curious. Are there any Electrical Engineers around these here parts? I, for myself, am an EE in training. Signal processing is my selected forte, and I'm perhaps a year from graduation. I'm curious as to wether or not I'm the only one on here (I doubt it.)

I wanna know who the other EE's around here are. We could form a little EE support group and PM each other when we had technical difficulties. It'd be great.

Lit. Inspired EE questions:
What is the best way to increase the RPM on my favorite vibrator?
Help! I'm getting voltage fluctuation on my cattle prod?
How do I filter the 60 hz noise out of the control circuit for my Hitachi magic wand?

So how bout it? Where my EE's at?

Please excuse him folks, he's a nerd from Cal Poly. He can't decide if he should wear his pocket protector with his beach shorts and cowboy boots.

Sun's out, surf's up. I say go for it, dude.

Yep, I'm a gEEk, full member of IEEE too.

To your questions:
Increase the RPM on your vibrator by adding more voltage. Instead of four batteries, try plugging into the wall with a full wave bridge rectifier? That ought to rev it up!

Voltage fluctuation on your prod is probably a dead or dying main capacitor. You could replace it or use a resistor/zener combo to regulate it. I wouldn't recommend a transzorb for this device, that'll blow out in no time during the charge cycle.

Filtering the 60Hz humm has always been a problem. A rather large ferrite bead helps, but usually a common mode choke would be more in order. Of course, none would fit in your wand, but then again, the 60Hz vibration can actually bring an added level of excitement for your wand!?!?

Good luck! At least let me know how the vibrator mod works for you!

Silly. Of *course* I wear my pocket protector with my beach shorts and (shudder) cowboy hat. I don't want my pens leaking on me when I'm at the beach trying to work on my pathetic excuse for a *tan*. Sheesh, *never* leave the pocket protector behind.

I used to have a full wave bridge rectifier, but I traded it for a Mickey Mantle rookie card. I think I got gypped.

Damn.

Well, at least you've got a sense of humor. You need that to deal with the quarter system and all those redneck ag students and their big-ass trucks on campus. lol

 

[Impetus]

Much as I would love to deal with the quarter system, it would make my impending graduation, not to mention the already-messy question of 'what exactly do I have to take in order to graduate?' even more convoluted than it already is.

And if it wasn't for the Ag students, we wouldn't have a sports team, and then we wouldn't have an athletic complex, and then I wouldn't have anywhere to practice TKD.

I was kidding you buddy. I used to be an Ag student there.

I hated that fucking quarter system though.

 

[KillerMuffin]

Not, EE. CS.


Personally, I really like agronomy, though. It's so . . .

Um, nevermind.

Lit. Inspired EE questions:
"What is the best way to increase the RPM on my favorite vibrator?"

Rewind the motor with finer gauge wire.

"Help! I'm getting voltage fluctuation on my cattle prod?"

Clean the contacts and change the batteries.

"How do I filter the 60 hz noise out of the control circuit for my Hitachi magic wand?"

Increase the size of the filter cap. on the output side. Or convert it to a switching regulator. The switching frequency should be 20 KHz or higher. If it's an AC motor, convert it to DC. Safer in the tub that way too.
