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?

[Mike(Mont)]

Actually i was thinking about copying this PCB format and just use perfboard and wires on the bottom of the board for the traces (scroll down the page a ways to post #212). That way it will look nice and clean--FROM THE TOP SIDE! LOL Rats nest underneath.

HAPPY NEW YEAR everyone. I hope your projects go good this year and that everyone hits a good one.

As for the ToTeM project, I guess I don't need anyone's help. This one is going to be a gamble because I'm going to hack the thing. And I'm not totally against a hand-held, just want to keep it away from my face and belly. So maybe it will end up like one of those devices they wheel around on a cart.

Well, my horoscope said to rev my engine because victory is at hand this year. Maybe they meant I am DUE for a good find. "Overdue" is more like it. LOL That's what I call a catch-all phrase or safe bet. LOL I guess I could write horoscopes, too!

Mike, good luck with this project . Maybe you can build a working version. And this project will come to life again. Health and success in the new 2019 with a new device and new discoveries!!!!
