8-Step-Sequencer
Various types of paper were tested, including photo paper, telephone book paper, color magazine pages, dextrin-coated paper, and catalogs from electronic supply companies. Different temperatures of a hot iron and varying pressure levels were also experimented with. Several board cleaning methods and chemicals were tried until a combination of etching agent and isopropyl alcohol was identified as effective. Two etchants were used: Ferric Chloride (FeCl3) and Sodium Persulfate (Na2S2O8), with plans to try Copper(II) Chloride (CuCl2) as an environmentally friendly closed-cycle alternative. The website's logo was inspired by a traffic sign seen on the Belgian Autobahn. The graphic work includes vector graphics related to signs for ice, frost, and snowflakes. The authenticity of the Belgian ice warning sign remains unverified despite research efforts. Even when using Surface Mount Devices (SMD), drilling holes for through-hole connections is sometimes necessary. A search for better methods before starting electroplating led to a novel technique, discussed with a friend, which is claimed to be significantly faster. The discussion inspired visual studies in spirographics. An old documentation of an 8-Step Sequencer created for the Piksel Festival in 2007 was updated due to minor errors. This sequencer features a 150-ohm current-limiting resistor and can output up to 20 milliamps to power filter circuits or toys. There is a request to avoid commercialization, especially regarding the gate circuit, which functions effectively despite its simplicity. A contact is provided for those interested in a custom extended version. Additionally, a KiCad tutorial is mentioned; KiCad is an open-source software suite for electronic design automation (EDA) that facilitates schematic capture and PCB layout.
In the realm of electronic circuit design and prototyping, the choice of materials and methods significantly influences the quality and efficiency of the final product. The exploration of various paper types for PCB etching demonstrates a hands-on approach to finding suitable substrates for transferring circuit designs. The combination of etching agents and solvents, such as isopropyl alcohol, indicates a focus on optimizing the etching process while considering cost-effectiveness.
The experimentation with Ferric Chloride and Sodium Persulfate as etchants illustrates the importance of selecting appropriate chemicals for effective copper removal during PCB fabrication. The intention to incorporate Copper(II) Chloride as a more environmentally friendly option reflects a growing awareness of sustainable practices in electronics manufacturing.
The design inspirations drawn from traffic signage and the resulting vector graphics work exemplify the intersection of creativity and technical skill in circuit design. The mention of the 8-Step Sequencer highlights the practical applications of such designs, showcasing the ability to create functional electronic components with simple yet effective circuitry. The sequencer's capability to deliver pulsed electricity to various devices underscores its versatility in both educational and hobbyist settings.
KiCad, as an electronic design automation tool, serves as a critical resource for designers seeking to create schematics and PCBs efficiently. Its integrated environment facilitates the entire design process, from initial concept to final layout, making it an invaluable asset for both novice and experienced engineers. The emphasis on avoiding commercialization of the gate circuit indicates a commitment to sharing knowledge and fostering innovation within the electronics community.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.
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: In summer 2009 I had a discussion with a friend of mine Andrzej WrG³blewski 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.

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.
