How to make this transmitter more powerful ?

[detectoman]

very easy abdou only should you put to finally output other step whit other most big transistor in total 2 transistors in serie or 2 complementaries transistors

Hello Dear All
Does anyone have original circuit of Alonso's PD ?
Please send it
Thanks

Hello
Dear All.
My new TOTEM PD is ready.
In the version, there is no potentiometer.
You can see its pics and video in follows:

Hello
My friends.
Can you share your idea (series 2 transistors)?

Thanks

I made a PD circuit board, it has been installed, there is no wiring loop experiment

Hi all
I have asembled this pcb of totem
That is woking very well
I advice the mem ber to make that

Nice job Zakari, shares the layout file pls. what are TX RX frequencies ?

I was thinking of building a ToTeM and not too excited about using the strip board. Poor eyesight (cataracts) is the main reason. I have a pair of those binocular magnifiers but not good enough. Even a magnifying loupe I can't see it. So my thoughts were to try to build on just a perfboard and follow the schematic "map" not the computer generated component placement. This way I will have more space between the connections so less chance of shorting. Is there anything I need to be warned about before attempting this?

Or if anyone has a PCB they are selling?

Good evening zakari. On the printed circuit board, you need to bring the power minus to the first leg of the timer 555 (U 7) according to the scheme.

Looks good, thank you.
