Arduino boards & parts (Shirley Center)

I think my hobbyist days are over and I'm not using my odd little devices any more. Don't delay or I'll change my mind! Collection of Arduino boards and related electronics. Approximate inventory:

3 plastic project boxes, used/repurposed.
Arduino UNO single board computer
Two Arduino MKR GSM 1400 (useless 3G, but SBCs are fine)
Two Arduino MKR NB 1500, I think one of them worked only with USB power.
Two 10W(?) 5 V power supply boards
2 single relay, one 4-relay boards (to switch 120V).
Small LCD screen
Various strain gauges, temp probes, temp & humidity probes.
Assorted components, terminal strips, prototyping board, battery.
