$50 Robot

[Bobb]

Hello, Society of robots

Got my bits through today for the $50 Robot  , i'm in the uk and used rapidonline as my source. . . Just one problem, the '28 pin DIP socket' in the parts list was discontinued, I ordered what I thought to be an equivalent. (order code 22-1719, if you'd like to see)

The socket that turned up wont take the ATmega8 that i have, its far too wide.

So, my question to you is; Can I take out the plastic bridge and use it as two sockets or just shorten the bridge?

As long as the pin spacings are the same, ya, you can just cut it into two pieces... Good luck

Hi,

Sure, it's standard 1/10" module, just cut the 3 middle "bars" out and solder each "side" at the right distance apart. Don't cut too close to the contacts if you use a side cutter, or you risk damaging it.
If appearance matters, use a metal file after cutting.

They must have had some sleepy dork taking your order. Not only was it a wide socket ordered with a narrow chip, but it's the most expensive type you got (not counting test sockets) - a wire wrap, tulip contact, socket.

Given you are in the UK then try Maplin http://www.maplin.co.uk/dual-in-line-sockets-2530
Not the cheapest but at least they lots of high street shops so you may have one locally.

You can use two 14 pin ic base one after another.

Thanks for the input people, much appreciated. I checked out my local(ish) maplin and picked up the right socket, but have struggled to find an ATAVRISP2 that I don't have to get shipped to the UK.

I was suggested http://uk.rs-online.com/web/p/microcontroller-processor/7055111/ as an alternative.

Given my track record now has a socket twice as wide as my chip and enough resistors to build a really short fence around my house. I was wondering if any of you nice people could vouch for that programmer working in the '$50 Robot tutorial' BEFORE I get it?
