    48 Signal generators

    Hi Brian Thanks for your help. Hmm your solution seems a fair bit easier. I was hoping that this could be used on future jobs as well so would be good to try and build a little machine. Another idea was to buy a little Arduino and get that to send out 48 different binary signals of numbers...

    48 Signal generators

    Hi Thanks for your reply Just trying to work out which is which. There is one hub then an outlet in each room. What I'm hoping to do it plug into all 48 sockets in the hub. Then go to each room read the signal, i.e 30mhz then I know which socket I have plugged the 30mhz signal into. So I would...

    48 Signal generators

    Hi I am currently working on a project where I will need to create 48 different numerical signals. This is to test out network points on old buildings. So what I would need is 48 individual signals that can be read and traced back to each signal. My most promising idea is to create 48...

    Charging circuits with diodes

    Hi The voltage drop may trip the Low voltage cut off actually? Do you have any other ideas? Thanks Chester

    Charging circuits with diodes

    Hi I'm trying to build a simple portable speaker. The only power source I can find is an old drill and charger so I have decided to use that. The specs of the drill power supply are 12.6v 0.5A, which then attaches to a Li-ion charging circuit. From initial testing the amplifier circuit pulls...

    [Moved] Very small sine wave inverter

    Hi Thanks for the fast reply! I've opened up the circuit and I can't see any Bridge rectifier, is there something else that will be doing this job? Thanks Chester

    [Moved] Very small sine wave inverter

    Hi I'm a student right now that is lacking on funds! In my car I would like to put in some speakers, I've found some normal household speakers that would work great accept they run off 240v ac, I've opened them up and seen that they have a transformer dropping to 9v ac (The transformer reads 9V...
