Ready for some more Rat Shack Nostalgia?
Here’s some. A 28-248 “Solar Power Electronic Lab Kit.”
This is a predecessor to the 28-255 kit, which you can see here: https://wereboar.com … he-power-of-the-sun/.
This one shows it’s much older heritage with the 1970s fonts present on the unit, lid, and manual.
We get some extras with this inside the box:
Like this old solar kit. This would have had a motor, plastic fan, and some other doodads with it:
There’s also the manual and a pack of wire that doesn’t look used at all.
Underneath, we have the main unit, which is a little warped from the years.
And the bottom is the standard spring terminal interconnects.
It looks to have been made in 1977, as denoted by the “7” on the number stamped on the back. I’m pretty sure these weren’t being sold in 1987.
Not sure what I’ll do with it, but…yeah. They’re still fun to play with.
