WRT it running in a browser I like the platform independence that offers.
Seems to also suggest that the computational load is in the Red Pitaya.
With it serving up web pages is it fair to call it a measurement server?

Couldn't find links to a US distributor.
Not sure I could afford it any way.

Newark is part of the farnell group so probably is the same.

They grow up fast, its just with 20 years between eldest and youngest....

I'm amazed at how many ways they can brand the same company.

My older brother and I are 9 years apart; 20 is quite a span.

Thank you for posting that!

I hadn't heard of it and need to do a deep-dive. Looks really cool.

in large scale production I have seen small specialty circuits come and go You mean like the 74C926? I have an idea: Why don't you code a PIC to emulate the 74C926 so that TS-1 owners who need one aren't orphaned.

That's a good price Bill. That CPC/Farnell site is new to me here in the US. It looks like the cables are the same ones we see here in the MCM brand at Newark. I've also used the Planet Waves umbilicals from Amazon when I used to shop there. They were good cables but a D to XLR breakout in that bran...

I haven't experimented using this servo with switched gains but I think it has advantages. Olaf alerted me to this technique in a mic preamplifier thread. Since I had a similar topology on my bench in the form of the MC preamp I decided to try it there. It worked so well I decided to use it even tho...

Negative resistors are a way to make oscillators ! You'll note that the positive feedback is rolled off at high frequencies (above fc) by virtue of it being an integrator. You can simulate the servo if you wish. I recall Gary Hebert of THAT doing a sim for me. I would use 1% resistors. The 2C integ...

I went back to my notes and remembered where the extra two bridge resistors came from. (R15 and R16). During my initial experiments I had the servo sense the INA output prior to the THAT1240 stages. There was nothing to pin the floating Deboo servo to ground so the added two resistors were required...

Breakers even better!

T-bias' benefit is the low frequency common mode rejection improvement. It is a capacitor value mismatch improver. I've never tried bootstrapping the CM in a mic preamp similar to InGenius. About the only complexity T-bias adds in a servo situation, where servo is injected into the inputs, is the re...
