Re: OPCODE 1-E Mono Cutterhead (Presto 1-D Clone)
Not sure the suspension box will fit on a Presto Overhead. The box with my overhead will certainly fit a Presto. So, you'd be replacing the entire overhead from the Presto with my system.

Re: Scam: Angulo aka Tangential Vinyl Disc Recorder C-4
I would say the same about someone else. But, then I would get in trouble. But, there is another whose work is just as questionable. And who makes a huge elaborate show of it.

Re: While waiting on the ebay gods...
Incidentally I have a way to do that with an all analogue recording path WITHOUT needing a special tape transport LOL ha ha ha ha ha ha. Magic? How exactly are you going to delay a signal via analog circuitry without addiing noise or distortion? Unless you have created something entirely new that w...

BLDC Motor Driver V2 Tomorrow I'll be testing my new driver code with this board. I got my motor turning with the previous board but it wasn't designed ideally. This board should be solid. I should be able to turn the platter again properly now. Hopefully I'll have video posted in a day or two! Pho...

BLDC Platter Motor V1
Only 3 of the 9 coils for now. The junk on top of the blue disk is just for weight and does nothing else.

PLS19 Overhead Sides I'll have rods cut, tapped and threaded tomorrow for the rest of the overhead. Two support rods, one linear bearing rod, and one threaded rod for a leadscrew. Then, I will start to write the motor control code and make the optical rotary encoder. First version will be accurate ...

Re: Linear-motion question
I'm familiar with microstepping. Unless you actually physically plotted the movememt of the microstepped servo motor, and then analyzed the plot at 200x magnification, then you really can't make the claim that the motor moves in a completely fluid manor. I can tell you, they don't. Sine wave or squa...
