Excluding system dependencies, a full ARTIQ-10 installation is under 10MB on OpenBSD 7.7 (using dynamically linked system LLVM)

Wavelength tuning of Ba+ spectroscopy lasers with Soundlocker and hollow cathode lamp. Column of ion fluorescence becomes visible in the lamp as the laser is tuned on resonance.

So why is the BUF634A better and the BUF634 not recommended for new designs?

Cheap GH0631IA5G laser diode in cheap vacuum chamber on cheap Stirling cooler (cloned all over China) = 614nm laser (Ba+ D5/2 repumper) under $1000

Should we leave GitHub completely in favor of git.m-labs.hk?

Green laser diodes (488/505/515/520nm) don't like cold! Wavelength stops decreasing below a certain temp, instead the forward voltage increases. If you keep pushing current through it, eventually the diode suddenly breaks (overvolt?), even below threshold. What explains this?

Fundamental and second-order modes of the Tesla coil resonator from the popular $3 Chinese kits

Hollow cathode lamp, LEE swatch book, solar panels, and modified Schoeps-style microphone preamps all being used correctly: #HardwareHacking #Lasers #IonTrapping

Reverse-engineered driver for ZWO ASI662 astronomy camera: git.m-labs.hk/srenblad/asi_u… No blobs, no bloat, and also works on BSD. Hardware is much more cost-effective than typical scientific cameras, and is already used in a few trapped-ion experiments.

Cheap 571nm DPSS laser pointer has a pump around 900nm (varies with temperature like a diode does) and broadband IR emission below 930nm. Visible line is sharp. What laser medium is that?

Cutest and cheapest Paul trap driver?
