The illustrated Walkthrough of PCB Production shows how I do it in my electronics lab since 2007. I heard of & tried the toner method years ago – but for a long time was less successful in reliably producing nice quality PCBs. I tried photo paper, telephone book paper, color pages of magazines, dextrin covered paper, the various catalogs of  electronic supply companies. I tried different temperatures of the hot iron, higher & lower pressure. I tried different board cleaning methods, different chemicals, until I could cut “the chemicals” down to the etching agent & maybe isopropyl alcohol (a cheap vodka would do as well).  Of the etchants I tried two: Ferrum-III-chloride  (FeCl3) & sodium persulphate (NaS2O8) but want to try etching with copper-II-chloride (CuCl2) as an e-friendly closed cycle alternative. Now here is my recipe at the moment:

My Website´s logo was inspired by a traffic sign I saw on the Belgian Autobahn some years ago. This little graphic adventure is some vectorgraphic work I did about signs for ice, frost & snow flakes & permutations thereof. If the “real” Belgian ice warning sign looks like I recall it, I could not verify despite devoting some effort to searching for it.

The long awaited reader reader for the CTM 2010 workshop, includes schematics & layouts of the shown circuits:

Here I made a quite useful table of SMD (SMT) component sizes:

Typical SMD sizes

Even when using SMD, from time to time we need to drill some holes for through-hole-connections. I searched the web to find a better way before I start electroplating. Instead of using little bits of wire I found a novel way, which at least for me is 10 times faster:

Thruhole Fabrication

This is a short intro handout for successful circuitbending (auf deutsch) :

This is the handout from a workshop in xxxxx, Berlin, a VGA-monitor as wave display:

In summer 2009 I had a discussion with a friend of mine Andrzej Wróblewski aka Bohomaz, stencil artist, about vector based pattern generation. This inspired me to do some visual studies in spirographics. Here you find some full resolution pdf – especially the first is a bit heavy in pdf rendering – but hey, it is A3 and easily can be printed out in A0 (all are Creative Commons 3.0 BY-NC-SA licensed):

This is the Schematic & PCB artwork for an STK4241 2x120W PowerAmp:

This is the Schematic & PCB artwork for a tiny LM4895 1W SMD PowerAmp  (only chip + four 1µF caps!):

Today Sergio from Mexico found an old documentation of a sequencer I made in 2007 for Piksel Festival. It contained several small errors, so here is the updated version of this nice 8-Step-Sequencer. It is simple but yet has some extra features. With a 150ohms resistor as current limiter. the sequencer can drive up to 20 milliamps to give pulsed electricity to filter circuits or toys.

Give it a try! Please NO commercialisation – especially of the gate circuit, which really works despite being so simple. Contact me if you need a custom extended version, there are several more astonishing tricks..

A KiCad-Tutorial - KiCad is an open source software suite for electronic design automation (EDA) – designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by Jean-Pierre Charras, and features an integrated environment with schematic capture, bill of materials list, and PCB layout.:

A Triac Tester - Had to work on a dimmer pack recently, I used & want to share this:

A Bat Detector - This thing works using only one chip, still EXPERIMENTAL:

TOB-Project Timeline

TOB project

TOB – Transmitting Object Behaviors

arrow-downTOB is an open project of the Berlin electronic artist red arrowJo FRGMNT Grys – over time there have been numerous members, collaborators & associates. Just to mention: Seamus O´Donnell, Kaspar König, Martin Kuentz, Jeremy Clarke & others.

The TOB production idea is derived from concepts of occupation of spaces and communication technologies and recycling/re-using materials:

1st level:- the input in micro-local space (diy vibrational microphones, kids toys, the guts of a videogame, fm receivers) is taking instruments, inner sounds of bicycles, selfmade electronic devices, feedbacks.

2nd level:- radio p.a. is supplying the next ambience with amplified acoustic events.

3rd level:- fm transmitters supply the wider ambience & are used for feedback.

4th level:- sometimes we transmit into global space via the internet.

The erroneous nature of all these communication ways producing interference, hiss, noises, hums – is part of the game.
