From childhood, I've loved making electrical things by soldering for some amateur radio related thing.
After graduated certain university and taking Ph. D, I did have a GaAs MMIC design working for 60 GHz system
but it's a bit long time ago.
I always love making something and would like to share my joy. Please enjoy my store!
