Yesterday Narrat1ve got a new (sort of) bench power supply in the form of an eBayed HP 6632b! You can read what HP says about it but it basically kicks as much ass as I could really want or expect a single output PSU to kick. Until now I’d been using a couple of Tektronix PS503a units (which are pretty great, actually) and a Power Designs TW6050a (which is very heavy). However in the course of figuring out some VCO stuff I found myself really wanting to be able to step by small numbers of millivolts and trust with some certainty that what I was asking for was what I was getting (and the 6632b’s microamp measurement is handy for embedded stuff, too).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Great PS….I have a couple in my metrology lab…
Hi, I have also ebayed a 6632B ps. I like it too.
Is it normal the device gets very hot (mostly on the top right, and and the bottom left) even when just running idle with no load ? How hot is yours after running for 2-3 hours ?
