    Political argument (Yeah, this is going to end well)

    Welcome home brother and Amen to that! We got egged and spit on as soon as our boots hit the tarmac in California. We did not break ranks though! 588th Combat Engineers Based In the Delta about 40 Klicks north of Cu Chi Class of 66 Chris

    You didn't answer the question.

    Increasing Voltage With Multiple Ignition Coils?

    OK, I think you've taken enough of a beating so here's my contribution to your topic. Isolation transformers aren't cheap and they're not that easy to find but step down 12V transformers are abundant and inexpensive. If you're going to continue experimenting with mains level voltages may I...

    momentary to on/off

    Is either pole of the switch committed to chassis ground?

    NFC reader

    There's possibly two reasons that there's be zero responses to this topic. One is members might consider this project nefarious. Two, ... It's homework.

    remote control amplifier

    How are you going to fit that in the remote? The board is 20mm and the LED looks to be about 10mm.

    grease gun using dc motor - current switch

    In order to give you accurate answers we need accurate information. This would include.. Motor draw under no load conditions. Motor draw under load (as it's moving grease) Motor draw @ 500PSI As far as danger is concerned, it's quite low. This is because grease gun cylinders are...

    Switching hydraulic solenoid

    Are you saying that you currently control it with a single switch that looks like this..'Extend - OFF - Retract' ? http://www.mpja.com/SPDT-On-Off-On-Full-Size-Toggle-Switch/productinfo/16082+SW/

    AC Adapter Question

    As Steve stated the current rating should meet or exceed your original model. This model exceeds your current demands, so it should be fine. http://www.mpja.com/75VDC-300mA-Unregulated-Plug-Supply/productinfo/17558+PD/ The plug type is 5.5mm OD / 2.5mm ID, with the female center (2.5mm) dia...

    Connector? I looked again. By golly that is a connector!:eek:

    Increasing Voltage With Multiple Ignition Coils?

    Todays electronics experimenters have far more cheap off the shelf (isolated) power supply options available to them than we ever had at that stage in our knowledge curve. So why are they constantly wanting to jump start their heart on the mains? Besides the shock issue there's the fire...

    Increasing Voltage With Multiple Ignition Coils?

    Just for the record.. While 100mA seems to be the magic figure that's considered lethal, hospitals work under much lower (JACO) guidelines. Bio-Med Techs are instructed that anything > 10mA through the heart is verboten. Anyone want to get into a betting pool on whether or not this thread...

    Convert Video Camera Battery into USB Power Source

    Hey, that's a super low input dropout! I'm not familiar with that chip but it's now going into my fav folder. CC, keep'n any other cool secrets? :D RE the kids: Keep em com'n. We desperately need new citizens that will actually work and pay taxes. :p

    Car Stereo Remote Control

    It took a bit of time to find it. As we've discussed in the nubies secret circuit circus thread, topic names are,... uh,... well we all know.. :rolleyes: https://www.electronicspoint.com/flasher-circuit-negative-switching-t249698.html Actually, this one ain't too bad!:D Chris

    Convert Video Camera Battery into USB Power Source

    Keep in mind that the input dropout voltage for the L78s05cv is 7.0V, so you don't have much headroom.

    Damaged exactly how? The focus is on the chip so the chip caps are blurry. I can't see the damage you refer too.

    Digital Pot setup

    I took a look see in the MCU library. It would appear that the PIC12F629, which is the older Picaxe 08 has the identical footprint of the 08M2. On that note, I would love to know what the hell the symbol designers were thinking when they made it so damn big!

    Digital Pot setup

    Hi Justin, Yes, you're absolutely correct. See, I knew I was right about you. You're an excellent student... like a dry sponge! This discussion is not about you... ;) https://www.electronicspoint.com/newbies-secret-circuits-circus-t250431.html Anyway, the Picaxe models were created by me...

    alarm door opener help

    It just occurred to me that you probably won't need the relay any longer. Here's the same circuit with direct drive to the buzzer.
