Modeling the circuit as a printed circuit board where the components are visible but the traces on the printed circuit board are not.
Part of the circuitry snacks project: Edible models of functioning electronic circuits. Designed for fun, for geeks, for kids, and for teaching and learning electronics.
The instructions are available here:

A 3-board design. 2"x3.25" overall.
Main idea was the breadboard adapter for the MSP430-Launchpad. The other two were added to make use of the space I was paying for anyway.
The top is a simple power supply to fit my breadboards (single side rails).
The bottom is my implementation of a "Mini-Launchpad". It's an idea I had to use some SMD MSP430s I ordered samples of by mistake and some SMD switch/LED combo parts I had laying around. It lacks the programming/emulation side, and only uses the 2211s I have, but it has most of the other features.
Les PCB, ou PolyChloroBiphényles, sont des dérivés chimiques chlorés plus connus en France sous le nom de pyralènes. Depuis les années 1930, les PCB étaient très utilisés dans l’industrie pour leurs qualités d’isolation électrique, de lubrification et d’ininflammabilité. On les retrouvait notamment comme isolants dans les transformateurs électriques et les condensateurs, comme lubrifiants dans les turbines et les pompes ou comme composants d’huiles, de soudures, d’adhésifs, de peintures et de papiers autocopiants. Ils ont cessé d’être produits dans les années 80 et progressivement été retirés de la vente jusqu’en 1987.
Ces substances sont peu biodégradables et persistantes dans l’environnement. Elles s’accumulent dans les organismes vivants, le long de la chaîne alimentaire.

I recently received the custom printed circuit boards I had made by OSH Park!
This one is for a 6x voltage multiplier based on circuits I studied online. Since it's a test unit I included screw terminals so I don't have to solder to use it. For the version that goes inside an actual amp chassis I will design another slightly smaller one with solder pads.
After designing it I created the board layout in Eagle. OSH made it so easy, too. No need to generate all the various gerber layers, just upload the ".brd" file and they do all that and show you nifty previews to check over before finalizing the order! They are now going to be my fab house for the indefinite future. :)
PCB of PIC16F819 based replacement driver for Honeywell CL15AE evaporative air cooler. Details about this project are available at jayakody2000lk.blogspot.com/2019/07/replacement-driver-fo...
In late 60'S, Multi-layer PCBs were very rare and expensive... Here is one sample, incredible when you think that it was hand-designed, Orcad was not invented yet...
Single layer PCB IR detectors and a few others. Card format 100x160mm. I just have to cutting the different smaller PCB's.
The boards are now ready to solder the components.

I recently received the custom printed circuit boards I had made by OSH Park!
This one is for a small voltage doubler. It rectifies 12v AC current for the tube filaments of a couple of 12EL6 tubes, and doubles the voltage for the plates. I'm not yet sure how well the 100μF caps are going to smooth the current since I don't have a scope, but we'll see..
After designing it I created the board layout in Eagle. OSH made it so easy, too.
