I have a free item someone's favorite electronics interested kid may love.  

Elenco Snap Circuits 300 in 1 Electronics Kit.

Have the 300 projects kit plus an expansion kit for another 100+ projects.

I believe all the parts and manuals are there, but no guarantees.

As a ham radio geek, I will genuinely miss my son building a working AM radio receiver on his own on a random rainy Saturday.

Think electronics building kit, with no wires to connect and with language-free Lego type instructions.

My guess at age range is 6 years old (for simpler builds) to about 13 years old.

Kids older than 13 may love it, but are more likely to live with a death-grip on their modern data phone device.

If more than one person happens to be interested, I will do a random.org drawing to pick a winner later this week.
