Rewind a week to the issues I had trying to upload the sounds to the board. I had just grabbed a usb cable I thought I had used before to connect the board to the laptop, but it wouldn’t connect???
After numerous attempts and system checks, I realised the cable was a power one not a power/signal one. Swapped cables and instantly problems solved lol.
After testing the sounds using my phone, i needed to actually test with the sound board. So after some wire soldering/connections, the board, amp, speakers where connected. I had ordered a potentiometer as a volume control, but it still hasn’t come, so I dug out a broken large servo and used the pot out of it. Quick YouTube/internet search, and it was soldered up according.
I opened up the ground loop unit to be able to connect up the speaker wires.
The amp uses 12 Volts, but the sound board runs 3-5 Volts, so has a mini voltage regulator [just seen in picture above it],
The sound output was great! And even more so, when I adjusted the 'volume' via the potentiometer, so much so that the wife told me to turn it down! :D
Here's a short video clip of the sound test, via my You Tube channel.
This new amp was originally going to be used as a separate sound unit for in R5's dome, but I think I might keep it for his main sound setup and get another [possibly] for the bad motivator dome setup.
Here's a size comparison between the two amps:
New amp on the left [small], original amp on the right [large].
The new amp cost about £5 inc P&P, compared to the SURE amp, which cost about £20+
