1 IC prototype board

Jan 25, 2008 12 Replies

I have looked all over the internet for a 1 ic prototype board. Radio Shack used to sell them, but have pretty much reduced their invetory for electronics. The board was patterned off of the 6 inch board only half as big. The board's pattern is


2 rows of holes tied horizontally on the top and bottom. These generally would be used for power-positive and negative.

The middle would be where the IC would go and there would be vertical rows of 5 holes per row.



I tried Digikey, but the pictures and descriptions are confusing. Does anyone know what I am talking about and where I can find it?



Thanks

is close but they didn't bus the outer rows.

Futurlec has some at

that are larger than you describe but also cheap and may work if you cut them down.

I don't know where you live, but if you have Fry's Electronics, it's worth a try going there. I saw a lot of small proto boards the last time I went there. Their site is

, but my impression is that they don't list everything they have.

If by any chance you live in the San Francisco bay area, there is a great local shop in Santa Clara - you can find them on

. They had many prototype boards too.

I never understood why those breadboards with the ground planes generally cost MORE than a breadboard without the plane. If anything, manufacturing them should use less etchant!

I suppose it was more of a supply and demand problem... many people were a little scare of shorting to the ground plane or just what it might "do" to their design?

The five year chart in the middle and the long term inventory at the end probably explain that:

It all gets recycled.

That, too. I had to introduce the ground-plane proto-boards even tio some seasoned engineers who several months later thought it was the best stuff since sliced bread. Because now their experiments worked :-)

It's all marketing. The $20 to $30 boards at Fry's cost pennies to make.

That board I laid out myself... ~12" x ~12", back in 1977, to breadboard a pin-driver chip for GenRad (1977 BS = before-simulators).

It ended up being a very useful tool to breadboard anything.

I've recently used up my last piece, so I'm thinking of rolling maybe a bunch of ~6" x ~4", something that will fit a standard "project box".

If you have some reasonably standard layout in mind, I'm sure plenty of other people would be willing to buy some.

The folks at One Pas

have some good ideas on how to make a breadboard useful for both SMT and through-hole parts by virtue of creative layout; something like that with a ground plane would be quite desirable.

Heck, just post a sketch or something and I'd be happy to draft up a layout...

Is there a "standard", readily-available-to-everyone, project box?

Are you talking about this (923273-ND), but with the power/gnd rows?

For about the same (or cheaper) you can get a no-name big one.

Go to Digikey, key in "Hammond", then "in stock", then click boxes. Tons of them :-)

No ground planes, it seems :-(

But their SMT to DIP adapters are low cost. Nice. Wish they had a DIP pinout though.
