Consumers of Electronic Complicit in Rape in the Democratic Republic of Congo? There has been widespread recognition that violent conflict in the Democratic Republic of the Congo (DRC) is fuelled by the mining and trade of its minerals.

Consumers of Electronic Complicit in Rape in the Democratic Republic of Congo?

Equally recognised is the fact that women are the chief victims of ongoing violence in the DRC: symbolically violated and subject to rape as a “weapon of war”. What is less well recognised are the possible links between these two issues in the Congo and the supply-chain which connects both of these issues to consumers.

    Wow, mind maps to file lists, I don't think that works.

    Okay... it kind of reminds me of the file system of a computer now... the mind map thing had obviously been lost there.

    Umm... this new look to pearltrees is confusing me. I will may take a little bit of time to adjust to it. It almost looks like pinterest now... the marketing dept. must have got into the design team O_O

    :) yes I'd rather pay someone to make a simple board with 50 components $100. Than to do it myself. Then just solder the components in. I've made a few boards in the past. Glad you found some useful info. L8trs Happy Pearling

    Excellent, just excellent! Thank you for helping me buddy. I appreciate it a lot.

    timepeaces thanks for your help, and yes: etching sucks and is messy hope that task can be done by 3D printers eventually--if it is not already done by them.

    Yncnathan If you do a short course, I suggest it is hands on, as soldering, and identifying what end of a diode is the correct end is something that is easier to learn in a lab assisted by a teacher. You also get to check out what I call spaghetti wiring, similar to the look on a bread board, but instead of etching a circuit board with tracks, you connect wires between the circuits components—and this can sometimes lead to leakage of signals between wires in high frequency applications (something to do with the wires, insulators, and air acting like a capacitor). You can only learn stuff like that in a practical lab unless you are into very complex theory and advanced studies.

    Yncnathan Dick Smiths used to be a good place to learn basic electronics, but I think they have moved away from that to more commercial electronics sales. You could do a short course on electronics, circuits, & etching copper boards. I hate the idea of using harsh chemicals to etch circuit boards, I think 3D printers might offer a solution, but I have not researched that area well, but know that the space industry is thinking of producing replacement parts using 3D printers, and that would include metal parts, so putting down circuit tracks on a board should be easy for a 3D printer.

    Yncnathan Electronics and electrical work can be very dangerous. Try and stick to low voltages (5 to 12 volts if possible) and use batteries unless you have a very safe way to convert high voltages into lower voltages.

    Most control circuits in electronics (even those that control high voltage stuff) use low voltage control circuits that operate on 5 to 12 volts.

    Timepeaces ref: the use of bread boards—very useful to test ideas and see if things work correctly before making a circuit board.

    Making a circuit board is messy and uses lots of nasty chemicals. A lot of components now days are getting so small that you can’t work with electronics in the same way as you did in the past. Unless you use Integrated Circuits (IC) your circuit board with components will look huge for task it is to do.

    This will give you some circuits you might like to use:
