<h1 style="color: red"> Low-Cost Digital Storage Logic Probe MKII </h2>
<hr />
In essence, it's a multimeter for the digital domain w/ storage capabilities. The download includes
complete schematic, draft article, but no software or PCBs (I'm retaining copyright to them) -
If you're reasonably confident with 16f877a controllers then you should be able throw together
some code in no time at all. Prototype performed well.

This looks like a really snazzy little tool. Are you marketing it? I'm interested!

The biggest hurdle I see at the moment for any KIT supplier is sheer cost. Very few people would pay AUS $100 for this, when they know they can go and buy a top notch multimeter with all the bells and whistles, which possibly includes a USB interface, all for about the same amount of money. Frightening stuff knowing that I can go and purchase a brand new 10MHz oscilloscope (with full warranty) for under AUS $130. DIY test gear is history.

Hi T.Jackson, Where is Offset, Zero and Span adjustment VR, for 0 to 15 v Calibration ?

There's no real refinement for the AC domain, sorry.

I'm not so sure, Trent. I've got four different Fluke multimeters, the oldest from the early 1980s. Not one of them was nearly that inexpensive. Nor were my three scopes. You may be doing yourself a disservice.

You would stand a better chance at winning the lottery than making a quid from this project.

Well, Trent, looking over this, and the scrolling LED project, I'm impressed.

Consider a couple of possibilities: Peddle the kits to someone like Gateway Electronics (they carry everything from little piddles to Ramsey).

Or skip the kit part and just collect several of your designs and publish your own books, a few projects at a time. God Himself knows it's less expensive to print a book of projects than to market the kits! (You probably aren't surprised to know that a lot of people will buy a $19.95 book to do one project out of it.)

Just a thought, because I'm impressed by what you do. (And sorry your scrolling LED seemed to get hijacked, however well-intentioned the others were.)

Good projects are good projects; those who fancy them don't really care how much they cost to build. It's the doing . . . !
