TGSL - EDU , new boards and kits

[Biogas]

Hi!

I dont find it: the connecting the Minelab coil PCB to TGSL! Somebody can post it?

The TGSL act with Minelab Coil PCB and with 2 tonnes PCB together?

Thank you!

That should get you started.

Thank you for that, but i already have that, and i made TGSL 3.0, but i need TGSL EDU PCB AND schematic !

Hello, where can i find schematic and PCB for TGSL EDU? Thank you in advance!!

hello
can i drive tgsl with a single 9v block batterie when i let out the 7808 an the two electrolytic caps nearby or are there any parts which need to be replaced too

can i damage the board components when i put 9volt direct


i have the feeling i could do it but... not sure

how does the machines from micromax line work? they have single 9v source


thanks for answer

I ran my first TGSL for several months with just a single nine volt source. For my final version I switched to two nine volt batteries in series to give more head room for the 8 volt regulators. The most recent one uses 8 AA batteries. Works well but with a slight weight penalty.

I'm about to turn my IGSL into a 9V rig in a few days, so if you don't mind waiting on my impressions just sit back and relax. I don't foresee any problems. Besides, I'll put 10ohm instead of the 7808 (~0.5Vdrop) and 10000μF instead of the 220μF one (C3 in TGSL). And a switch to chose between the two batteries.

installing resistors

If you have trouble fitting resistors horizontal due to there size and dont like fitting vertical providing you got the room all you have to do is kink the leads so they go partly underneath each end of the resistor as shown, we done this for years in the TV trade.

volume control

If you want to fit a volume control use 1kohm wired one side of track from + speaker output other side to common - and wiper to speaker.
Using log type is better but lin type ok and does the job.

Hi silverdog! i didnt get a bc547 just 1x c32725 and 1x bc327 but not to worry i have used a bc548 i had and it should be fine as they are pretty much the same tranny! ok great on the tl071 il stick them in and get on with the coil great kits by the way silverdog and loving the baracuda really please with it many thanks andrew...

[silverdog]

Also in silverdogs kit i have tl071's instead of lm308's will these work? as im not sure they have the same pinouts? andrew...

TL071 are fine

[silverdog]

Hi all! in my kit from silverdog instead of the bc547 i have been sent a c32725 is this a mistake? as the former is a npn and the 32725 tests as a pnp i probably have a small general purpose transistor sub for the bc547 kicking around so... just checking with the forum im not wrong? cheers andrew.....

The c32725 is a BC327 which is correct, you should also have however a bc547

Alpha Pots with Switch

A listing:

a good cheap source of pots:

Had a sight with all the Alpha pots with switches just having trouble locating the link somewhere within my 100 saved sites...LOL
