Any good summer electrical projects?

Ah, yeah, the Jags are pretty awesome because of that. You can get the Victors here:

And the datasheet is here:

They are fairly pricey, but good DC motor controllers in that power range are. If you don't need 90A continuous power I would scour eBay or google products search for 48V motor controller. Good luck in your project.

As awesome as that would be, I just don't have that much money to drop on a project at the moment.


Also, here's a quick question: I'm trying to build an intervalometer (timed trigger for time lapse photography) using a 555 timer. the schematic I'm going off of calls for an NE555 timer. What I can pick up in town are the TLC555 and LM555 chips. Looking at the spec sheets I can't tell a significant difference between them, but I'm not sure. Are there any significant differences between chip numbers I should be aware of? or are they just different numbers between manufacturers?

[JamesCH95]

I think the 555 timer is pretty well uniform between manufacturers, but the pin-out might vary. As long as the data sheets are the same you should be fine.

alright. that's the impression I was getting, but I just thought I'd make sure

Chris,
555 timers are for the most part interchangeable. Some manufacturers have added something to make it better but still equivalent. There are CMOS variations as well. The CMOS requires less power supply current but can't handle higher output currents like the standard version. You might try getting several and fooling around with some to make wild noises as an audible alarm when the time out is reached.

I would welcome you to come out to Monroe, and help me wire in the power windows that I'm trying to transplant into my car. I need help!
