Hello Everyone!
I'm New to EDA boards. I'll make a Quick OT Intro, I'm Ragav, a Radio Amateur, from Chennai, India. I'm Mostly into Software Defined radio's and RF circuits by default.
For a Few days however I've been reading up on Microcontroller projects and would love to get my hands on them.
For this I've been looking for a suitable USB PIC programmer ever since. I came across a lot of designs on the internet for such a programmer, but none have met my requirements so far.
I prefer to Use BJT's for Programmers and Save the FET's for RF applications, mainly because I feel that they are too costly and second reason being, why use a difficult hard to find part when something common is available. I'm also looking for a design which derives power from the USB as I'm not really a fan of ICSP. I'd be trying to use a ZIF socket for the programmer. The other major requirement I'm Okay with would be minimal solder side jumpers. Why do i need this strange requirement? I'm Planning to help college and school kids assemble these programmers as a part of a volunteer classes on "Introduction to Microcontrollers". Kids and Oldies, alike are prone to solder the jumpers in all sorts of wrong locations all the time
Although I can live with basic 5V devices, a 3.3V addition would spice up the programmer even more. The Programming on the Go is not something we are looking at.
Any schematic/boards/ideas which meets my requirements will be truly appreciated.
Also Please Note that I'm not planning to BUY a Already assembled programmer from the sellers who lurk around at these forums ( one exception exists) who wanna make the maximum buck for something that is available for free from other hobbyists. Please keep off this thread if that is your Intention.
As a homebrewer, I'd rather make something than Buy! (Unless it really has a Exotic parts)
Sorry If my post sounded authoritative or harsh at any point. But from experience on certain forums has taught me a lot! Hope to find better people here.
Thanks and 73 (Radio speak for regards)
