PBP projects for R/C models

Does MICROCHIP make an auxiliary board that contains drivers for the PICkit 2 device? I am not capable of soldering onto that PICkit printed circuit board. I already have a good sized non-solder proto board carrying the four DPDT switches, two proximity sensors and a voltage regulator. I am trying to get this whole thing onto a 1/10 scale radio control car.

The guy from whom this idea came used a PICAXE.

There are more logic level MOSFET's than Carter has Liver Pills (an expression that easily shows my age).

What I want to do must be very standard.

Suggestions?

I find these handy. Mouser has them.

Just to confuse the issue a tad more, one of the other options would be to use a buffer/driver IC like this:

Digikey has 'em for under $2, and it gives you up to 6 outputs if you like. MAX current is 40mA.

I did a quick search for nice little MOSFETS in a small through-hole style package (like to-92) and I've gotta say it's pretty depressing. 98% of the stuff out there these days is SMD.

Dave, those little dual MOSFETS are cute. But I'll bet Ken would like something in through-hole...

I grabbed my "TTL Integrated Circuits Catalog From Texas Instruments" dated 1 August 1969 and found specs on the SN7400, SN7401, SN7402, SN7403, SN7404, SN7405, and SN7410!!

This SN7407 thingie must be one of those newfangled inventions. No wonder I did not recognize it

Thank you all!!

Heh, you've got me beat for "vintage databooks".

I've got some National Semiconductor "TTL" and " Analog" data books that go back to '74, and a Signetics data book from '76, but nothing that goes back to the 60's...

Hey, It's 2010 and that means the NE/SE555 is celebrating it's 40th birthday!

Am I the only one that finds that amazing? 40 years in production for an IC type..

According to Wikipedia:
"As of 2003, it is estimated that 1 billion units are manufactured every year." Wow!
Sometimes technology doesn't change that much, it just gets... smaller.
Oooh look, now available in a TSSOP8 package.

You're doing great Ken, and I'm looking forward to seeing photos of your car in action because I know you're going to get there. You're clearly a geek at heart with experiance behind you ...
You just need some fresher data books to work from.

You're doing great. Carry on.

Sends you on a nostalgic trip, doesnt it?

My dad used to work in the avionics department of our national carrier, and I remember he showed it to me as an example of cutting edge technology.

Of course, I could only appreciate the significance after he showed me the equivalent transistorised module it replaced.

"What will they think of next..."
