Small Plugboards (sometimes called 'breadboards')

[MrAl]

Hello,

Here are some small plugboards, the kind you normally use with little jumpers and maybe one or two IC chips and some other small parts. The parts are plugged into the board rather than soldered.

We got these at a really good price, like $9 USD for 10 of them. I got 5, a friend got 5.

Question is, do you guys use these too for anything? I find they work ok for digital stuff like microcontrollers, but for precise analog stuff they get a little questionable. Also they have extra capacitance so they might alter the operating frequency of some circuits, more or less.
They are still quite usable for some things however.
These are all white in color but they also come in various colors these days

These things are used a lot in colleges and are OK for low speed/low frequency applications.
If you are interested in them there is a website dedicated to using them, complete with well thought-out software at www.fritzing.org . E

I measured 6 pF between adjacent rows.

Hi Ya MrAl,

Most of what I worked with was low frequency stuff and in my lab I had several larger versions of those boards. Every time we had the technicians build a prototype they were done on those boards and as far as I know since my retirement they still are. Most were mounted in large sections on a plate that also had fused +5, +15 and -15 volt power supplies. When the boards wore out they were replaced on the plates. Those little boards were a real good deal Mr. Al. The bottoms could likely be fitted with that double stick sided foam automotive tape so several could be laid out on a metal plate (ours had screws). I used them as a regular part of development.

Hi again,

canadaelk:
That site looks interesting as they make PC boards too for people who submit projects.
Not that cheap though unfortunately.

NorthGuy:
Really that's all? That's not much really considering that's about the estimate for two IC pins on a PC board.
So instead of 6pf we'd have a total of about 12pf.

Ron:
Oh yes, these have the adhesive back too, but i never use that anyway. I always hot glue mine down to something else
What was interesting about these boards is that they are so small they fit almost anywhere, and for one or two IC circuits should work out good for regular stuff/
