That's reassuring, I bought four in that recent order with a view to making an Echobase. Is there any way to check them other than making the whole circuit and discovering it doesn't work?

not that I am aware of, however the standard circuit is very simple and would make a worthy testbed.
otherwise, Id just build the pedal if you arent going to be doing many pt2399 builds, if it motorboats, get new ICs

I just can't see the Americans falling into line with the rest of the World though anytime soon, so we will just have to live with the problem i suppose.

Main problem with changing to metric system is the lack of visual references. We have a finger joint for an inch reference;
a foot for a foot, three feet for the yard. If were stuck without a measuring device we can still approximate with body parts.
But the metric system is hard to get a handle on. What's a cm based on? Or mm? It all seems so arbitrary. Now we did try
to change over a few decades ago. We created an engineering ruler. It still has inches, but are in 1/10" increments. Single and
dual in line IC's use this system and circuit boards were drawn out on 1/10" grid graph paper. We may be stuck with this
system until IC's are replaced. Hey, it's a step.

SMD ICs are defined in mm aren't they?

Anyway, my middle finger is 3cm for each joint, my little fingernail is 1cm wide, 15cm is the same length as the rulers we've been using all of our lives, and my leg is a metre long from the pelvis to the end of my toes.

mrs rocky's foot is not the same length as mine.. nor are her finger joints.. sorry, but this just makes no sense to me.. if I want to measure something, I use a measuring device

I always have my phone on me, it's got a ruler app if necessary, but seriously, when I'm doing a job that needs me to know the length of something, I use a device to measure it.. think the comparison to body parts is a bit of a stretch (if you'll pardon the pun).

If you're on a desert island without a measuring device, simply refine some sand into a 555 chip, then bounce your laser off any convenient shiny faraway object and measure the time it takes to return. Speed of light will give you the distance, so you can construct a proper meter stick. Then your stick raft will finally be square, and Wilson will no longer smirk condescendingly at your efforts.

Apparently you could stand a little historical lesson. The following is from Wiki':

The Egyptian cubit, the Indus Valley units of length referred to above and the Mesopotamian cubit were used in the 3rd millennium BC and are the earliest known units used by ancient peoples to measure length. The measures of length used in ancient India included the dhanus (bow), the krosa (cry, or cow-call) and the yojana (stage).

The common cubit was the length of the forearm from the elbow to the tip of the middle finger. It was divided into the span of the hand (one-half cubit), the palm or width of the hand (one sixth), and the digit or width of the middle finger (one twenty-fourth) and the span or the length between the tip of little finger to the tip of the thumb. The Sacred Cubit, which was a standard cubit enhanced by an extra span—thus 7 spans or 28 digits long—was used in constructing buildings and monuments and in surveying in ancient Egypt. The inch, foot, and yard evolved from these units through a complicated transformation not yet fully understood. Some believe they evolved from cubic measures; others believe they were simple proportions or multiples of the cubit. In whichever case, the Greeks and Romans inherited the foot from the Egyptians. The Roman foot (~296 mm) was divided into both 12 unciae (inches) (~24.7 mm) and 16 digits (~18.5 mm). The Romans also introduced the mille passus (1000 paces) or double steps, the pace being equal to five Roman feet (~1480 mm). The Roman mile of 5000 feet (1480 m) was introduced into England during the occupation. Queen Elizabeth I (reigned from 1558 to 1603) changed, by statute, the mile to 5280 feet (~1609 m) or 8 furlongs, a furlong being 40 rod (unit)s (~201 m) of 5.5 yards (~5.03 m)each.

Oh my!!!

This is like finding the Rosetta Stone! If we can get this info distributed around the states, this may cut decades (maybe even
centuries) off our conversion to metrics.

To answer your question......it depends on the crowd...

Sorry if I misread your post. I took it as light hearted banter until you said "seriously" and then seem to think it was a stretch
to use body parts as units of measure. I took that as a sincere statement. I replied trying to show you that body parts were
indeed the basis of measurement. Again, sorry to upset you...wasn't meant to insult.....only enlighten. I've re-read your post
several times, and I still can't read it to mean anything different than the way I first took it. But I know now that it was a remark
of jest that went way over my head. If I could remove my post, I would. One thing I've learned about this forum is that you
can't say much without pissing someone off. I guess I don't type in an obvious tongue-in-cheek manner. Sorry, wish I did.
That being said, it's either risk pissing someone off occasionally or don't play at all. At this moment in time, I choose to play.

bro.. I'm not pissed off.. this is all part of the banter isn't it? .. so historically if a woman weighs the same as a duck, is she actually a witch?

couldn't you use a bit of vero 2x5 holes to mount the pot and solder the wires to?

Yep, I've done this on a number of occasions and it seems to work well. I use pins from right-angle header connectors to solder to the PCB:

^pretty cool

Great idea! only problem is the pots I got from tayda... alpha ones with the sweet little plastic dust/conductive covers, dont fit into the holes of the vero and perf I received from them. Do you have to sand down the terminals to get them to fit? I was also thinking I could enlarge the holes on teh perf but I thought that might ruin the copper traces. eh?
