hi Polo,
Few month ago I saw that my GBC was in your top10, really happy if you like it ! Be safe, it's not destroyed!
Since 2 years I build rc trucks, we get more fun in exibitions. I spend less Lego time for GBC but I have 2 modules in my mind, of course not easy one's!
The first is a new GBC Writer with only 1 C+ motor, 1 PUP color sensor and a Train Hub, so very cheaper than the EV3!
The second is a connect 4 GBC, were people will be able to play each other with a pup remote or aigainst the program.
Yes I'm living about less than an hour from PG52 (his MOC are so clever... cars, gbc, ski-lift, really interesting to discuss with him during exibitions).
Oh, you mean you live in the same region ?!
