Circuits that techies need ?

I'm thinking of developing a product line of circuits that 'techies', educators, science researchers, and some engineers could use.

I'm asking for your suggestions.

What I'm thinking of so far is simple analog circuit boards, populated with SMT components, that are adjustable (can be tweaked over a wide range). Basic op amp, comparator, instrumentation amps, filters, differential versions, wideband versions, etc. In two forms; Bareboard with trim pots, switches, and screw terminal conection, and enclosed versions with standard controls and banana or bnc/sma connections.

Of course, most 'techies' make their own circuits, but I could see junior engineers and scientists enjoying the luxury of having a simple 'development' board they can try and tweak in their system rather than spend too much money or time. Those are my ideas.

It would be interesting, very interesting, to see what kind of circuits you folks think might be viable. It doesn't have to be simple.

What do you think ?

Hmm so your plan is basically to make some modules that can be tied together in order to form a reconfigurable system. And the modules can be trimmed to match the application.

I dare to doubt if it would be really interesting to work with 'black box' modules. I think it is more interesting to tie together 'basic' resistors, caps and transistors. With special modules it will be hard to explain the blackboxes so well that the user knows exactly what each potmeter/trimcap serves for. The knowledge that you get about the box is not so useful as the knowledge about the real resistors / capacitors / transistors / opamps / comparators.

Do you know the Philips 'experimental boxes'? Below was the one that made me enthousiastic for electronics:

The only 'module' there was a robust opamp with decoupling and some compensation circuitry, the rest was discrete wire components. A system with special 'springs' enabled rather reliable connecting.

What I liked:

1) many nice applications possible, ranging from humidity sensor, bistable and monostable multivibrators to 'beeping' devices and even a heterodyne AM radio receiver. 2) good documentation so you can understand what you build 3) cheap components readily available for replacement or expansion.

Sno-o-o-o-ort! Must be tough to be young and pussy-hunting all the time ;-)

Better keep it secret. If she gets her own, males will be obsolete.

A device that from a short distance can stimulate the pleasure centre in the brain(?) of a Female thus making her belive that she is actually enjoing her techie date enough to get her clothes off laterrrr.

Or a device that would hypnotise women to get their clothes off.

Or maybe a device that can be sold for enough money to get certain womens clothes off - that saves engineering time too.


Maybe settle for a device that can be exchanged for about 10 pints at the local, which will make any slag look attractive and increase the odds of scoring to 1 ..... ok, as long as one can get away before she turns wherewolf in the morning.

Young (!), Hehe: *any* personal problem can be turned into an advantage - look at Hugh Heffner, a looser geek who made a magazine with pictures of nekkid wimmyn so he could at least get to ogle the models while they took the pictures ....
