    Designing a SuperCapacitor Circuit

    magicasd, charging _anything_ to 700-1000 volts sounds weird, let alone using supercaps for it. That's more like a carbon-arc lighting demo than an LED demo. Are you sure there isn't a typo or misunderstanding involved? Like maybe your teacher wanted you to charge to charge to 1000 microfarads...

    Optima burglar alarm fault

    Lloyd11's advice is good: Look for the user and installation manual. I'm not familiar with Optima panels, but I have a lot of experience with alarm systems and batteries employed in most burglar alarm systems. Most by far use a sealed lead-surphuric acid rechargable battery and, no, you...

    Free Engery

    And speaking of free energy: Kudos to Estonia for developing a strong WECS (Wind Energy Conversion Systems) base in their economy. Not that I'm an expert about Estonia, but they're located right along the Baltic sea and have no mountains and have low hills, so it always seemed to me to be an...

    Honeywell 6150 Keypad Troubleshooting

    Definitely take the zone loop wires off the wire terminal lugs before measuring loop resistance. And definitely take the 3K off the smoke sensor; but if I were you, I wouldn't put a 2K on it yet. You'd just have to take it off again when you get your ohm-meter in hand. If the fire loop EOLR...

    Honeywell 6150 Keypad Troubleshooting

    Kent, about that fire loop--yes, I didn't bother to say much much about it, but all fire loops have the devices wired in parallel. Fire devices are required to be open-loop devices (relay open in "normal" condition, closed in alarm) by Code--and in fact, whatever panel Westec used should have...

    Honeywell 6150 Keypad Troubleshooting

    Westec 4000? I'm not familiar with their stuff and from what I've read on several other forums, neither are most experienced alarm techs. They apparently weren't that big in most places. I haven't been able to find what equipment they used--it's highly unlikely they made their own. The only...

    Amplifying DC voltage

    You can boost DC voltage without going through an inverter. Google "dc voltage doubler circuit diagram" and ignore the pay-for-download sites. Hobbyists have been doing this for a long time. It's going to take some sizable capacitors to make it, though. I don't know if you'll be able to build it...

    Josh, looking at the specs on devices can be misleading. You're apparently looking at a specfic model design and specs (specifications) for your numbers, which I will accept at valid. So "the electric motor driving the vehicle only needs 12 volt 22 amp 264 watts", okay, but that doesn't mean...

    ultrasonic sensors

    Don't know if this helps you, stranger, but the alarm industry used to use lots of ultrasonic sensors decades ago, before they were supplanted by passive infrared sensors. I don't know how the car sensors work, but the ones in alarm systems measured relative velocity between source and target...

    Honeywell 6150 Keypad Troubleshooting

    You're welcome. If you ever decide you'd like to have a used utility programming keypad for future contingencies, I can make you a good offer. I'm an old alarm tech and have extra Alpha keypads lying around that are perfectly functional but not nice-looking enough to install. Just in case you're...

    Honeywell 6150 Keypad Troubleshooting

    Kent, you need to set the keypad address. You do _not_ need to go into the control panel programming to do this, it's Keypad Local Programming---nothing to do with Panel Installer Programming. First, I assume you returned the green & yellow wires to their proper places? (1)Power the panel...
