Help! My Sonic Screwdriver has too many sounds!

[Agentsmith350]

Same here , even bought two so i had a spare to tinker with and both have the extra sounds :/

There may be a way involving fiddling with how the switch works if you are keen on trying that. At present it probably switches something integrated into the circuitry of the sound unit, but if you could hard wire that closed, and instead have the battery supply switched, that may work. You could test it by taking out the battery, holding down the switch and reinserting the battery. If upon reinsertion of the battery, the driver makes the 'first' sound, and continues until you take the battery back out, and this repeats each time you reinstall the battery, you might be onto something.

Tested this and its as you say , when the battery is removed its the first correct sound that plays when there back in there

In that case, i think you have an option to modify how the activation switch works. You need to make it so that the activation switch operates on the battery supply ie so that it switches the main power supply. If i had one of these drivers i could dismantle it and do a guide as i suspect it would be quite easy.

I drew up this diagram to explain how I think you could modify the switch. As you can see, you need to make the switch operate on one of the main power supply wires from the battery, and hard wire the original switched wires so they are permanently closed. In my diagram the original setup is on the left, and the modified on the right. You can switch either the positive or negative supply from the battery, it doesn't really matter.

Thanks dyno , tried that today only difference being i used the positive on the switch but im not getting any life from it , multimeter shows that its getting battery power through the switch ok but dont know what else i can do , seems the board may have gone ?

That really shouldn't be the case providing the test I explained previously worked (IE holding down the activation button and taking the battery in and out and seeing if that repeatedly made the 'first' sound). If it worked using the test method, then rewiring the driver per the above diagram simply replicates the test scenario.

Perhaps try putting the driver back into it's original configuration, replace the battery, and repeat the test scenario to see if it really does respond in the way we were thinking it might?

I had to solder the switch wires straight across and its really crappy thin wire and just kept stripping so am not sure i can put it back how it was , i did bypass the switch which should act as it was before just with the switch constantly on but no change.

Damn ! Didnt catch the part about holding the switch in , just tried it on another one i had and it dosnt make any sounds when the battry is back in until you let go of the button and press it again

 

[Agentsmith350]

Did a bit more on it today , managed to get it back to how it was but ended up replacing all the wires as the stuff they have used is like hair and just kept snapping. Seems ok just need to solder the switch back on but seems ok when i cross the contacts. ( cant put button on yet due to work im doing on the battery cover ) shame we cant get rid of those other noises !

Bugger. In that case you are probably scuppered and the idea won't work, as you have found out!

A part of me wonders if a replacement dipole switch (which operates on both the battery and activation switch seperately) would work...

I see what you mean , Iv just had a look but dont think there will be one small enough.
