Hi,
Yes This little Bluetooth board works quite good. I tested it with some music, using my smartphone as transmitter.

Sound is clear and good. Also in direct near to the working DelTang Rx there was no interfering interaction in my test.

What I perceive as disturbing is that this thing talks to me and says things like "ready to connect" and "connected", each time it is switched on.

The loco hood is no actual 7/8" loco. It's from an old G-scale loco with a built in speaker, only used for testing .

An example of how life isn't always that fair Helmut. Recommended for bravery with one hand and seemingly recommended for the sack with the other! All part of the blame game and compensation culture era I suppose.

Juergen sent me a photo of his new experimental sound rig. It transmits sound by Bluetooth. We have exchanged quite a few eMails on the subject. Juergen has also now tested the 'impedance convertor', which I also recieved today. Juergen & I have also both now ordered a 'reverberation' board. This will add 'ambience' to overly 'dry' sounds.

I thought getting my head round "layers" in my photo management software was a brain basher but this takes the biscuit! Looks like the route to the canteen at a cheapskate holiday camp - round in circles so you never find it but see lots of distractions on the way!

Hi,
here's my temporary Toeffelholm Soundbox

The converter is directly connected to the speaker outputs of the sound module to transfer the amplified speaker signal into a line in signal for the low pass filter and a bluetooth audio transmitter. The sound module is fed by a separate DelTang Rx65, that works in parallel to a Rx in the loco.
Si and his profound knowledge of audio electronics helped a lot with this.

Maybe I find time at the weekend for some sound impressions.

Here's the sound-test situation on the loco side with the bluetooth receiver Si introduced before.

Of course Dr. Sartorius and his assistant provided their help for performing the test. :brill:

Is the dude with the speaker a Tamiya 1:12 motor-racing guy Juergen ?

Yes he is from Tamiya. It's a loan from a friend for some pics. Difficult to get nowadays.
I will introduce my figures in my 7/8" figure thread later on. But recently I concentrate on the Toeffelholm Sound installation.
