Voltages in series add up. It's why we combine cells into batteries. Here he's just substituting a charged capacitor for another battery. But then he charges the capacitor with the original battery. If you take a 9V battery apart you're find six 1.5V cells in it. There's two styles. There's the packs and there's the cylinders. Packs are stacked and cylinders are side by side. Also 9V battery cases are always made out of sheet metal that's one hundredth of an inch thick. So I use them as shim stock a lot. Don't matter who made the battery it's always 0.01" Must be some battery cabal conspiracy stuff.

@@JDTeam You can describe inductors in terms of long water pipes. When you have a large mass of water moving in a pipe, suddenly shutting a valve at the end causes "water hammer", i.e. that momentum in the water to develops a high pressure if there is nothing in the line to redirect the momentum to (e.g. a hammer arrestor in the water line, or a flyback diode across an inductor). Though it's more complicated in electricity because the magnetic field is part of the "storage" of momentum, it's pretty much the same principle. Electric current, like water current, has momentum, and doesn't like to change.

I used DRAM and programmed a 1702 EPROM one byte at a time with hand assembled binary from the OP codes. Finally got it working before I graduated but only after switching to the Z80 which had Ras and Cas refresh lines for the DRAM.

Oh wait, would a simple voltage divider work or would that waste energy in the resistor? Guess I’ll go find out!

@murasaki848 Жыл бұрын

I'm actually curious if you got it to work with a simple voltage divider. My back of the envelope calculations were questionable as to whether it would work (and especially work with a narrow enough voltage swing and simultaneously without letting the magic smoke out of the R1 resistor on the divider), especially since I can only guess at your overall maximum current draw (which will vary wildly depending on the operations your computer is doing). In any case, if the voltage divider doesn't pan out, try getting a 7805 regulator (a very popular device since before I started haunting Radio Shacks in the late 1970s) and a heat sink. The 7805 is still just a linear power supply, so you'll still be dropping 4/9 of your power into that heat sink powering it with a 9V battery, but it might work well enough. Edit: If you've never heard of them before, the 7805 is based on the LM340 adding components for a fixed output. They also have internal protections against thermal and overcurrent. The "8" in the part number is the positive series, and the "05" means 5 volts. They make others, most notably the 7812 (+12V) and the 7905 (-5V, the "9" indicating negative going), two others near and dear to me. 😊

That would be a very wasteful, low current, HOT, circuit... 🔥 As mentioned, a simple LDO regulator circuit would be the next step up, that would work ok. 1 I.C., and 2 capacitors is all that would be required.

IIRC this can, with a little reconfiguration, be used to create a negative voltage rail for use with devices (like op-amps) that require a dual power supply

Best demo of a charge pump that I've ever seen! Really clear, concise, and fun. To the folks out there that want to play with this more, there is a DIP IC, the 7660, that is specialized to do this very thing, that used to be commonly used to generate a negative voltage where you need a low current negative voltage to run some sort of signaling or analog circuit.

I never got to be a EE, but I've always loved electronics. Did the build a color TV thing through DeVry, and I'm a ham radio operator. Built circuits to run stepper motors for my telescope, etc..... I really enjoyed this video. I kept waiting... When were you going to introduce the diode? One thing I learned early on too was, it's not the voltage that kills you. It's the amperage! This is a great illustration! Thank you!

The two complementary clock signals can also be easily generated from a microcontroller's GPIO pins if, like you suggested at the end, you want to generate a higher voltage rail for a particular interface like RS232 or RS485. Driving the GPIOs straight into the capacitor is probably not a great idea, since the maximum source/sink currents on the MCU would probably be exceeded if you did that, but the MOSFET arrangement shown earlier in the video would work perfectly, with one MOSFET attached to each pin. The total maximum supply current is quite low in this design due to the resistors, and lowering the resistances significantly decreases efficiency, so if you need more drive current, you can use a MOSFET push-pull buffer on each of the two clock phases. Designing these push-pull MOSFET circuits to avoid shoot-through (where both MOSFETs turn on at once and short from +V to GND) can be a bit tricky if you try to do it from scratch, but there are really cheap MOSFET driver ICs designed to do exactly this (often called "high-side/low-side drivers"). For bonus points, you can set up your MCU to output PWM at 50% duty cycle on a single pin (this uses 0% CPU because the PWM is generated by a hardware peripheral), then hook up a MOSFET as shown in this video to invert the output, and use the non-inverted and inverted signals to drive the two separate MOSFET push-pull circuits from a single GPIO pin.

@thewhitefalcon8539 Жыл бұрын

Each switching node, and the original input, effectively uses up the same amount of current that you get from the output. If you have 5 stages (plus the input) and want 5mA out then you need 5mA into each stage, a total of 30mA. Of course it only flows half the time so it's 10mA when it is flowing.

Question, why does your oscilloscope or really all oscilloscopes not show or have a setting to see the volts on the side of the lines. Like when you said 5, 10, 15, 20 volts.. You sorta had to guess at the range. Why can't there be a button to turn on that shows the numbers on the left side of the wave form so you know 100% what that voltage is?? I bothers me they never have that feature. Is there a legit reason why...seems a no brainer.. Cause even you had to sorta guess at the range ?
