Subject: [alt-beam] SE help again
Hey its me again. I have taken Steve's advice and tried to debug my FLED SE
but its still doing the same thing. I have a 2N3904 and a 2N3906 that I am
using now, but I have also used 2N2222A and 2N2907 combinations. Everything
gives the same reaction. The 4.5 VDC 100mA converter with a 2.2K resistor
charges the 2200uF cap (I have connected some caps to get up to 5500uF).
Then the FLED fades in and starts to flash then.... "twitch" .....the motor
kinda convulses and the whole process starts over. I don't have a meter of
any kind so I have no idea on the actual voltages. The motor is taken from a
Sony sport Walkman and the other motor I use is from a CD player. Not the
motor that spins the CD but the other one. I think that's everything. thanks
for the help
Power = 4.5 VDC 100mA
Trans = 2N3904 and 2N3906
cap = 2200uF
FLED = Green
Resistor = 2.2k
motor = Walkman motor
