The Secret Society of Lathe Trolls

Hi, Sharing results Cutting stylus, not embossing, made of tungsten lapped and polished with diamond paste, I have done this to test my setup without the risk of damaging my diamond stylus, useful for testing chip extraction, lathe control, lathe sequences, audio level etc At first relatively noisy,...

Yesss, I wasn't expecting that much precision from this thing

Mmm everything is good, So 6.946 Ohms and 24 deg C at sample #512 7.126 Ohms and 30.21 deg C at sample #6389 So delta temp is 6.21 deg C R=Rref*(1+alpha(T-Tref))) Rref is 6.946 ohms Alpha for copper 0.00393 T=30.21 deg Tref=24 deg 6.946*(1-0.00393*(30.21-24))=7.116 ohms close enough to measured 7.12...

Hi, So conclusion and final results, 2000 lines of code later, working great at some extend for what I need, pink noise applied so you can see volts RMS, Current RMS, Watts RMS, Temperature measured near the junction of the voice coil former and alu spider NTC 3950 SMD 0402, total energy, each sampl...

Hi ! Updates of this out of control project that I need to stop working on haha So finally reaching the end of this measuring acquiring thing, decided to push it to the max, so cheap LCD character module, assembly code PIC16F877, computer communication dumping data via ttl / usb serial port to txt f...

Hi, Yesss, I use a yamaha P2100 power amp, so no relays or DC protect, I have a startup controlled sequence for the power amp, audio cut, speaker out into dummy load for initial thump, wait, then I think audio to amplifier, speaker out to head, inverse kind of sequence when cutting the amp, This is ...

Hi, So I have found a nice place that sell high purity Helium with the regulator for around 250$CA including taxes, one more thing solved The thermal RMS prototype if someone is interested It will be less ugly and less burned in the end, i'm trying to find the limits before the solder melt or other ...

Ok this is really excellent and it will be part of my next head build, but first I will cut some stuff and see how loud and long I can go with this setup, I have done quite a bit of glue research and ended up using the 1ml cyano lepage glue for my coils, go figure the ''same'' cyano glue in a bigger...

Ok so for the flow rate at first was not sure that this could be find via google or AI overviews or or.. so Neumann head 0.05 SCFH around 0.0008 CFM so this explain the fact that you keep the cavity filled to allow better transfer to the rest of the assembly

Hi ! Happy holidays ! So decided not to put ferrofluid in the gap of my custom made magnetics, done some measurements before, really improving heat transfer to the body of my assembly, also reducing amplitude of my main resonance.. but still really not sure about this, how it can affect the transien...

Still looking for a print of a download, there was a link but never was able to pay via the webpage.... you have found something ?

Thanks,

Hi !

I have a something similar, what was the problem in the end ?

Thanks !
