I think that will end up being more convinient and actually lower cost rather than using a perf board and wires to solder everything together. You can print and put the symbol of the gate on the top as well so the same pcb can be reused for all of the gates. It' also a lot easier if you want to add leds on the inputs/outputs. --- End quote --- I once got a PCB from Elecrow with a special offer 10 pcs of 100x100mm for 12€ including shipping. But that seems to be gone. https://www.allpcb.com/online_pcb_quote.html?hidLength=50&hidWidth=70&hidNum=10&countNumer=10&txtSelNum=&hidLayers=2&Thicknessquote=1.6 With this manufacturer the shipping is free. Otherwise that will add up. Those perfboard where not expensive, but the time to create one gate module is near 4 hours now. Going with SMT and designed PCB’s sound attractive then. However I would need to buy new parts also (or bend the pins). |

I like this idea. I volunteer to teach a beginners electronics class once a week and we haven't gotten to digital design yet. I think I will use your idea and make several for demonstration purposes, I will likely just give them breadboards and IC's when we get to the hands-on lab portion of that concept. Thanks for being my muse in this instance! |

This is what I got * Stickers with symbols in Visio, great tool for parameterized 2D drawings * Case/box in FreeCad, great tool for parameterized 3D designs * PCB layout in KiCadBut all of them are ready for a 2.0 revision. |

Some time ago I built some "Circuit Tiles" as I called, to teach something about electricity to my kids. Searched the internet for some games, but found nothing available in my country, so I build some stuff with the thing I had. Saw some games that had magnetic connections, some would clip, others had connections like puzzles... My option was to interconnect the modules with alligator clips, using crimping terminals with a nail inside to secure them to the wood base tiles. Since in your case, with a lot of connections to logic ports and such, I think an option could be use terminals like the Arduino boards has, and the connections would be made with jumper wires (like those used for breadboards). EDIT: Why invert the type of connection you showed? Because you can even use simple wires with the insulation striped on the tips to make the connections, in case you run out of jumpers. And you could dedicate to each port, not just one interconnection pin/plug, but 2 or 3, since you may have to interconnect them with other inputs/outputs. Leave you with just some ideas... I'm curious about your work, because I might be interested to move from electricity tiles, to electronic tiles. So your findings and options, may be useful to me. :-+ |

The reasons I choose male pinheaders is because: * With the counterpart - the females it is harder to create shortcircuits, so no problem to have them hanging around. * I couldn't find any other silicone prepared wires: it needs to be flexible, otherwise the modules don't keep their location/alignment * Wires are of high quality but also cheap, so its easy to have enough of them * The pins on the PCB are very durable and strong, male connectors can easily break * The pins are a self defence mechanism, so no one steps on the modules that took so much time to create ;)It is always possible to cut one end and put a male one on them. When it's time to interact with an Arduino I might make headers with stickers on them. Haven't thought about it yet. All the gate modules will probably become redundant by then (I guess). First I will also have to create modules with comparators, oscillators, etc. :-+ Switches, potmeters, LDR's will probably just be wired with Dupont connectors. |
