Made a nice oak case for my USB random number generator.

I needed a hole punch capable of reaching deep into large material for punching center holes in vinyl record blanks. Unfortunately, the longest reach of any hand-activated punch I could find was just 3″. So I built this (admittedly overkill) hole punch.

I recently bought a cheap VU meter on Amazon, which looks very cool but needs some circuitry to get running. Unlike vintage meters, which can be driven by the audio signal directly, newer (and especially cheap) meters require DC current. A simple circuit, based on this example by Rod Elliott, uses four diodes to convert the AC audio signal into DC, plus a resistor and capacitor to dampen the movement of the needle.
See Rod’s post for lots more technical detail and a more complex driver circuit. Of course, this is pretty lo-fi and not studio-quality equipment… it also didn’t cost $1000.
I got this very small tabletop microscope today for inspecting record grooves after cutting on my lathe. It was going in the trash over at the Stevens Laboratory for Multiscale Imaging (where they have the electron microscope) but it’s perfect for White Noise Boutique!
