Hi all, Do you remember me asking if the HandyBoard was working on an iMac with an USB/Serial adapter? Well, all the USB/Serial adapters have been back ordered for the last 4 months, so I was unable to find or try any of them ;^(. But I bought an (...)

Dear Mike, I believe the 16 V is rms value. If you attach a capacitor across the bridge rectifier under no load condition(output terminals are open), the capacitor gets charged not to 16 V rms but to the maximum value ie Vm=16*2^0.5 which is about (...)
