Hi Chris, Right now it is only audio (a 386N4 op-amp) but, seeing your post set me to thinking as, I have 4 different Arduino UNO microcontroller boards; each having timers, clocks, amps and ways to record and send info to 4 line LCD displays (all stuff I already have in my 'junk box' of electrical stuff; as you can see, I delve and tinker big time). So how hard could it be to program the microprocessor to measure time between tick and tock and send that information to the LCD display. As soon as I get it all cooked up, I'll post more info and photos of the finished product. Too cool, man!! Hi all.I have not been here in quite some time.just busy. Anyway, what a great project. How did you create the pizo pickup?

Guitar amp software basically gives similar sound to real amps. This software has come a long way to the point where their sound quality and realism is hard to tell apart from the real thing. Overloud TH3 is a premier guitar amp software which comes with loads of features that makes it a must get software. Beat – Simply functional. Solid, all of a piece. Thus, the design of the BEAT is best described. The compact and powerful analog amplifiers are well processed and good „motorized“. The clean circuit boards with SMD layout is well thought out and structurally characterized in the small but effective.

How do we count the beat? By this I mean that is the entry counted as one or is it the entry and exit of the verge that makes one beat ie tick or tick tock?

Would love to create a Timetrax or Microset type device and save $$!! I suppose this could be also coded for basic stamp or pic micro-controller. Thank you for sharing this!!

I would think that using something like a micro-processor like a Raspberry Pi over a micro-controller like the UNO would be a better choice.

Especially if you wanted to get into some good analysis work. Would definitely be a lot quicker. But not sure about that as a timing machine may not be all that taxing. Sista 4 all the sistas around da world raritan.

But Ren has a few UNOs on hand so may as well use one and find out. You may already be aware of the timing apps that are available on the market for iPhones, iPads and also for Androids. I grabbed a couple of youtube links to a couple of these apps.

I think there may be many more on the market now. Not sure how much they are (maybe cheap I hope!) but they are pretty cool. Here are the links: If anyone has price info on any of these please post it up here.

Soldered alligator clip to ground 180* from the wire. Dipped connections in Plastic Dip. Nothing fancy, can actully hear pulse on wrist when run through amp.

So far the project is only an amplifier. I still am working on a successful sketch to also run an LCD and record the timing using the tick-tock as a trigger mechanism. Not much luck so far.

For anyone following this thread all these high tech sounding words we're throwing around up here are not really all that tough to figure out. Most of the technical programming work has already been done for us in these Arduino modules. You just need to tell them what you want them to do. Sometimes if you're really nice and speak in a friendly voice they do what you ask of them.really depends on their mood at the time. For me they are usually pissed off.
