Is this supposed to work?

Hi friends

I just stumbled upon a website, qrp-popcorn.blogspot.com, where this image is published. This looks so weird I'm asking myself if this is actually supposed to work? how?

(is this really just a free-floating PTP construction, and all grounding is soldered onto the copperplate while the parts are connected in the air? Is this grounding working?)

Why not? If it isn't high frequency staff than everything will work ok.

This technology was used in RF techniques especially RF pre amplifiers as they mount in a screened box as a ground plane, to prevent stray capacitance and interference problems.
Looks like it will work but very Heath Robinson!

Or very Bob Pease.

I think its looking very (VERY) cool.
I am really fond of (lacking a better expression) this ways of bringing love to stuff.

Or, perhaps the constructor had simply run out of etching fluid?

> this is actually supposed to work? how?

The ideal circuit board has "NO" effect on the circuit operation. So why have it?

The primary problem here is that if the Rolling Stones take it on World Tour, or even if you ship it UPS/FedEx/USPS, parts will break off. The conventional tag-strips and boards give more support. And also don't need so much thinking to assemble (thinking is done in board design).

It excels for radio prototypes because a clever skilled builder can make critical connections very-very short, butt-to-butt if needed. I have done it for audio because I done so much 'clever' soldering it just comes natural. But not even for local road-trips, this build may be fragile. (It is possible to make it really robust but that needs skill and luck.)

ah yes, the "dead bug stuck to a glue trap" style :)

Rad, isnt it?
Im tempted to try it myself on a ACA (with paper-surrogates to begin with :) )

That thing's nothing more than some slop mess.
And anyone constructing such crap shouldn't have access to a soldering iron.
