AVR ISP MK2 to IS hookup cable
« on: January 22, 2010, 10:39:17 AM »
I am working on building a connector to plug into my AVR ISP MK2 2x3 header connection and the other end will be IC hookup connectors. That way I can just attach them directly to the IC at the proper pins and not worry about problems with trying to get a row of headers to stand up in a proto board and run a bunch of connections.

Anyway I say all this to ask this question. Does anyone think this would be something they might buy and use? Single prototype cost is upwards of $12. 6 IC hookup connectors cost a lot. However if I make a lot of them I can get the cost down. So 2 questions how much would you pay and would you buy it.

I think I understand what you are proposing, and if right it is similar to something I did years ago. My variation on this theme used these:



To clip the ISP circuitry directly onto a DIP package microcontroller.

Yah I'm gonna use these guys



Then you just clip them on to the pins and go. My latest project I used servo extensions and cut the shroud of one side to expose the pins and inserted the entire thing into the proto board. however I still had to run wires to just program it. Makes my boards look messy and almost doubled the amount of wire I had to do. Will make my life easier so thought it might makes others lives easier as well.

6 times as much "clipping" but probably 1/6th the cost.

Sign me up for one or two of your ClipISPs :-)

http://www.dealextreme.com/details.dx/sku.8391 Not the best quality but at 23c each...
I would buy it but it would depend on the price, if i can make something for $5, would i really pay $10 for it?

Thanks for the link smash. I may order some and see if they are good enough quality.

I did some investigation and preliminarily I can make a different version that would work but is not as universal. The IC hook version works with prototyping board or an assembled pcb. If I switch the Ic-hook for a male connector pin I can make them a lot cheaper but they only plug into proto boards and nothing else. I'm gonna make my prototypes for my own use and might be able to put several together for rather cheap if some people from here want one. I'm already talking to sparkfun about distributing them if I where to actually go into some sort of production for the unit. However they don't seem to interested. Also judging from the popularity of this thread maybe the market is to small for it anyway :)
