A QRPme Pocket Pal II could be a suitable project for a Squidwrench “advanced soldering” class:
Yes, it comes with a tin case:
You must fit your own insulating sheet under the PCB; polypropylene snipped from a retail package works fine.
It’s intended as a “mint tin sized tester for all kinds of hamfest goodies”, but it seems like a nice source of small currents, voltages, and signals suitable for stimulating all manner of circuitry one might encounter in later sessions of a beginning electronics class.
Before using it, of course, one must solder a handful of small through-hole parts into the PCB, a skill none of us were born with.
For completeness, the back side, hot from the soldering iron:
The kits (always buy two of anything like this) arrived minus a few parts, which I suspect was due to an avalanche of orders brought on by a favorable QST review. Fortunately, I (still) have a sufficient Heap o’ Parts to finish it off without resupply, although a hank of 9 V battery snaps will arrive in short order.

Is it time to resupply the 9V battery stash? Running short code there. [grin]
Two batteries to go …
I keep my spares in the fridge, but I’m using so few 9V batteries, the Costco packs might be overkill. Let’s see, 2 smoke detectors and the mattress controller. In the shop, the DVM and the laser level remote when I’m using it. Yep, next time it’ll be a 6 pack or equivalent. I’m already doing that for C cells (one radio).
I retired the last C-cell user last week – the motion sensing back porch died – oxidized plastic broke and wasn’t worth fixing, not when a Home Depot solar light was on sale – 50% off.
I’ve pretty much settled on AAs and Ds, and 18650 cells.
