I took this old PCB out of a broken DVD player to see what interesting colors, shapes and textures could be saved from this now piece of junk.
50th photos on Flickr. Since this is my 50th photos. I'll make a little change to my Flickr. From now on, for every photos I uploaded, I'll write a little description about the photos. The description maybe not too long but at least you know something about the photos. Ok, about this photo. This is some old photo I found when scrolling down Lightroom catalog. I shoot this at some seaside which is not far from my hometown. But when I shoot this, it come out to be a little dull since I shoot it at noon. So I convert it into b&w and the result I think is better than the colored one.
Location: Pantai Cahaya Bulan, Kelantan.
D3X/Mamiya 645 45mm 2.8 N/extension tube/SU800/Metz 52 AF-1 (2x)
Got it cheap from a used store, unfortunately it's a dud. Returned for a refund. Before it was returned, took some naked images of the mic to capture the mechanical art inside. :)

The PCB Group Order! Woo!
The full 22x16 panel, with a lot of empty space. I could've fit a bunch more boards.
PCB's for the led light modules. Step by step we go on. There are a lot of PCBs necessary for driving the LED modules. Everything should now be drilled and cut.
The PCB's are:
40 key matrix keyboard.
12 Cree ledpower module.
8 channel FPGA output driver OC.
6 channel high power driver for cree leds
4 high power color leds holder.
4 channel high power color led driver
4 x 4 connector interfaces for power cables.
This is a video running at 4X speed, illustrating the etching process I'm using. The paint is removed from the copper-clad PCB in an Epilog laser cutter. After a wipedown with alcohol to remove any paint dust, the PCB is etched in ferric chloride solution.
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.
This project is a 5.1-channel, USB analog audio processor based on PT2322 and Arduino Nano. This inexpensive audio processor contains 6-channel individual channel attenuators, a 3-way tone control system for front-end speakers, and a 3D audio simulation system.
Additional information on this project, including the schematic, PCB layouts, compiled binary files, and complete source codes, are available at jayakody2000lk.blogspot.com/2022/10/51-channel-analog-aud...
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.

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.
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. :)
