Has anyone created a PropClip to breadboard adaptor?

MarkS

I want to buy one type of Prop programmer. I'd prefer the PropClip as that's how I plan on designing any board that uses the Prop, but there is no good way to use the clip with a breadboard. It seems like an awful waste of money to buy both the Clip and the Plug, just so I can use a breadboard.

This is what I have in mind:



It's VERY small and could be produced for pennies. Hundreds of them would fit on a single production PCB blank.

Oh well. Interest or not, I'm going to get one made. It will cost me less that $20 for one from BatchPCB. Not exactly a deal, but I wont have a redundant piece of hardware.

Piece of veroboard?

As the Clip uses the exact spacing of 2.54mm it will fit nicely onto a tiny piece of a striped breadboard; use a little bit of tin at the Clip side..
I have done many of those "support modules" for things that do not fit well on solderless breadboards - which are many

My latest contribution is a video-adapter of 12x16 mm, using angular 5 pin headers (5 cents), half of an RCA extension chord (1/2 x 60 cents), 3 SMD resistors (6 cents), hot.melt adhesive, and bespoken tiny piece from a breadboard (5 cents) = 50 cents.... If everything works fine I can do it within a quarter of an hour... I need still 8 for my next class...

Edit:
@Graham: So it's "veroboard" what I am talking of

Neat adapter Desilva, I did similar for my prototyping system although I prefer yours:

Yep, veroboard's the stuff. Some plain copper clad and a knife/dremel would be another option for this problem spending $20 would be a waste.

I've made two or three similar things for other devices like the Microchip ICD 2 at home, etching my own boards.

I'll try the veroboard for a prototype, but I think I'm going to make these.

I can fit 30 on a 4" x 3" board (maximum freeware version of Eagle board size), which works out to about $2 a piece if I use BatchPCB. If I were to use a 90° female header, it would convert the clip directly to a plug. Throw in a 90° 4-pin male header and you have breadboard access. With limited production sizes from BatchPCB, I could sell these as a kit for less that $5 each. If I had a full version of Eagle and could populate a full size production PCB blank, the price each would drop to less than $1 and the kit would cost about $3.

Maybe SparkFun might be interested in this as a new product...

I just got the board from BatchPCB. I accidentally sent them the files for the original board (.61"x.5") instead of the new board (.5"x.5"). Still, this thing is tiny. Its hardly bigger than a quarter with the female header attached. I'll post pics as soon as I can find a camera.

Hi MarkS

For prototyping purpose i mill my boards with my LPKF machine.
Today i have milled the P8X32-40D module for my prototyping system.
The system is now called UMDL, and as soon as i have finished my homepage i will post it.

I got this made and forgot to post pics. Here they are...






It works well, although standard male headers have different pin lengths on each side of the plastic thingy. This poses a little problem. Easy to fix, but still a problem.
