I keep getting emails from the founder guru, and keep telling him that
his demo schematics are obviously stupid.
1. Few people in tech actually understand electricity.

2. Most people are strongly affected by peer pressure, emotionally
influenced by other opinions and group concensus.

So an electronic design collaboration with high group visibility is a
terrible idea.

There might be ways to fix this.

I assume this is another \"Doing Hardware is just like Doing

And they\'re motivated by the appeal and relative
success in collaborative digital platform development.
Where, the software components are highly defined
structures and standardized; the programmers (\"developers\")
use all sorts of support tools to allow for a distributed

It is progress, in that people can join & leave the team.
So labor cost can be managed. Ah hah!
It can take time to get major things done. Tasks are
broken down & prioritized into \'sprints\', etc.

So what do you think - Can Hardware be broken down
into same ways & managed like software?


I wonder how much actual invention, creating new architectures, is
used in software projects, as opposed to just grunting out a lot of
code. Grunting can reasonably be parallelized.

Certainly a few software structures needed real invention: internet
protocols, file systems, file formats, os kernals.

An electronic design can be broken down into parts. Someone can do the
power supplies, someone the real signal electronics, and other people
the FPGA and uP code and PCB layout. But I think one skilled badass
should be in charge.

Who decides what psu voltage to use?
\'No, I refuse to run the valves at 5v B+.\'
\'But this TRF reflex neutralised project shows it can be done. It\'ll save us another supply. And look, it even boasts near zero sensitivity!\'
I did suggest that the person in charge should be skilled.

Of course. There are still plenty of opinion differences.
\"TRF reflex neutralised project\" is old-timeish radio, which was
interesting. What\'s different now is that voltage gain used to be hard
to come by, and now it\'s basically free.

Now we get double conversion, SSB, reliable ICs, microprocessors & informative displays, stable operation, digital readout, SDR etc etc. I still prefer the ancient stuff though. Ingenious, charming & cranky are ok with me.

I like early radio too--some of those components were real works of art,
especially multi-gang variable caps with plates sculpted so as to give
linear tuning with shaft angle for both RF and LO circuits at once.
Besides, I\'ve used a bunch of early radio techniques in optics,
including making crystal radios that worked at 200 THz.

Given a 200T detector, did you make a superhet?

I\'ve considered another receiver topology: locate a second antenna
near the receive antenna, and short #2 with a diode driven by a square
wave... sort of a chopper effect.

Given a 200T detector, did you make a superhet?

I didn\'t, but Christophe Fumeaux did it by mixing two CO2 laser lines
near 30 THz, yielding an IF (in wires) up to 168 GHz.

I\'ve considered another receiver topology: locate a second antenna
near the receive antenna, and short #2 with a diode driven by a
square wave... sort of a chopper effect.

That\'s more or less how my ACTJ modulator was supposed to work--see

FWIW I think all the once new reception techniques were ingenious. I just don\'t enjoy the more modern ones. We only see them as not ingenious because they\'re familiar to us. Early radio did so much with so little.

There were electromechanical oscillators, negative resistance oscillators & rotating oscillators before Armstrong\'s.
