Need Help with Circuit Design

I need some help with the design of a few things. Is there anyone out there who can help get me started and provide guidance and design help with the following?

  1. A TFT LCD hand held Huntron style deceive. I know the spec I want but I don't know the best way to go about building one.

2.Labview/National Instruments. I need some help in choosing the hardware for a IC tester.

I do want to pay someone because I want someone to put some thought into these things. If you have experience with Analog/Digital circuit design and LCD stuff and Labview I would need anywhere from a few hours to 10-20 hours to get me started in the right direction. This is for my personal use and is not any type of commercial use do I don't have to rush this out. Please email me at StateStreetAmusements (at) hotmail dot com

I'd suggest first taking a look at all the various analog-style curve tracers available and studying their schematics. Huntron trackers started out as not much more than uncalibrated/not-necessarily-so-linear curve tracers, since they were just meant to provide "good" component/circuit signatures that could be compared against question kit in productoin environments.

Once you can design an analog curve tracer, the rest is just digitizing the results and displaying it on an LCD -- other than the ADC interface, perhaps, this is all software/digital/straightforward.

What kind of ICs would you like to test? There's everything from digital logic IC testers (7400/4000 series) that run a few hundred bucks to multi-million dollar probers for die-level testing of multi-GHz mixed-mode systems-on-chip.

So what is the spec? What exactly do you want to do/test?

Is this related to 1. above? What sort of IC tester? Why do you need an IC tester? Is it for specfic chips or a more universal type thing?

Dang that takes me back. An ex-navy electronics tech showed me that circuit 30+ years ago.

The original curve tracer. :)

BTW, I was a TV broadcast engineer in the Army over 30 years ago.
