what if transistor never developed?

what field of work / hobby next choice be?...   (this leave things mechanical open along electricity, incan bulbs, relays, generators etc etc)



remember first computers used thermionic valves ( tubes )

imagine quad core pc tubes !  , of course memory cells magnetic rings :-)

all stuff built valves ( tubes ) , in 1962 ordered 1 transistor radio kit  ( crystal set oc71 transistor driving earpiece )

i excited waiting it, , when arrived, examined magical transistor, , broke 1 leg off !

the supplier believed how arrived, had wait few days replacement.

hello, im confused uno r3, uploaded code quite few months in uno, working fine. now without having altered of circuits, trying upload code changes,im getting strange error "avrdude: verification error, first mismatch @ byte 0x0000          0x0c != 0x62" i tried research able solve issue,  im running kind of fuse bit being changed or clock speed altered, im pretty sure did not play around these items. any people, please . . thanks taz Arduino Forum > Using Arduino > Installation & Troubleshooting > avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62 arduino
