    Homemade capacitors, that hold a charge?

    I wondered too, when I saw the article in the 70's, but as I don't know the formulas I took their text for granted. Maybe it was a typo (1F vs 1nF?).

    Building MIDI-Keyboard scanner - circuit layout and lag?

    Thanks for the info, Harald. :D A company near us specializes in data-cables, including multi-core TP. I'll probably have to use 36-pair so I'll pay them a visit. Regards, Clive.

    Building MIDI-Keyboard scanner - circuit layout and lag?

    Hi. Planning to construct a keyboard scanner / controller (1): The decoupling caps all appear to be in parallel (pin 16 Vs to Gnd), so does each IC see 2uF (20 x 0.1uF)? (2): On 16 of the IC's it shows Vs connected to pin 16 and pin 6. Where should the 0.1uF 16V mini-disc caps be physically...

    Homemade capacitors, that hold a charge?

    Hi @Sally S .... (1): Another experimental capacitor you could try: Build a "Leyden Jar" capacitor. It's a large glass jar with foil stuck around the inside circumference, the other "plate" being another layer on the outside. According to the magazine article, the value is 1F! (1000mF). This was...

    What is this part

    @Joebrad27 . If possible you may want to upload a close-up of the track-side, either through macro-photography or flatbed scanner. Also to partner that, a perpendicular "aerial shot" of the component side. Then a isometric view from 4+ angles around boar's components (sharp focus), to help...

    Shake Flashlights power

    To illustrate @BobK 's point: A 12V dynamo is connected to a DPDT relay, which feeds a heavy load (bank of lamps). Dynamo is operated via pulley/belts by turning a crank. No load - smooth sailing, easy to crank. Energise relay (load connects) - suddenly you're "straining" against the...

    Web-tech multiple questions: Graphics Dims, DPI, GIF & Video

    Hi EP forum members. Even though I’ve used various forums for some time, I’m still fairly green when it comes to certain specifics. I read that 200 Kb is the maximum byte-limit for uploading images to Electronics Point. This is easy enough to do by resizing and XY dimensions and / or...

    Series or parallel fans for max cooling ?

    Hi again. Re my original question re series (stacked) or parallel fan configuration. Other than a Hoover Aquavac, I don't have any forced-air sources, 10-gallon or otherwise. The welder cycle has since been explained by a qualified welder (rods too thick). My curiosity from a purely scientific...

    Series or parallel fans for max cooling ?

    Thank you @Bluejets and @Tha fios agaibh for coherent to-the-point replies. Yes, it does have a built-in duty-cycle (not a fault) designed for thermal protection. I'll keep it 'as-is' as per helpful advice. :) That is, if we have el-ec-tri-city in "the jungle". :rolleyes:
