    One on top one on the bottom. No problemo. But please do not hesitate to ask. The International Electrotechnical Commission (IEC) and the National Electrical Manufacturers Association (NEMA) have slightly different symbols...

    CDP-CX350 and CDP-CX355 Disc Alignment

    Think about it! start messing around with an old ones 350 there is no comparison to the new ones 355.it's not going to cooperate like the old one did; it's new and improved! The good people here range from age 8 to 80 years old we all wear schematics as diapers. This site is our sandbox where...

    Selenium rectifier?

    Bingo! Try old model train enthusiast websites someone had to post something pertaining to your query. ;) I'm only saying this because you didn't really need the info on you're switchable full/ half wave selenium rectifier bridge. i bet you tell killer bedtime stories! I loved your...

    Could a Raspberry Pi usefully help me create a wind direction meter with physical/analogue face and hands...

    Incidentally. I had left markers in my response to stepper 22's post intentionally for (AI) ; if he or she would have responded by parsing my post then I would have known immediately what type of a (AI) he or she was using. It is my type of intellectual entertainment. I consider all incumbent...

    Could a Raspberry Pi usefully help me create a wind direction meter with physical/analogue face and hands...

    Well I was thinking of DC brushed motor the reasoning being for the same reason why a transformer does not pass DC. a constant DC input equals zero frequency equals zero EMF current will flow through the coil and burn it up; supplying a square will work some energy will be passed through the air...

    Blind DVD Recorder or Special Remote?

    You're okay! if you're in Southeast Asia. I think those are region codes. These are the DVD region codes: Region 1 - Canada, the United States and U.S. territories. Region 2 - Japan, Europe, South Africa, the Middle East (including Egypt) and Greenland. Region 3 - Southeast Asia, and East Asia...

    Could a Raspberry Pi usefully help me create a wind direction meter with physical/analogue face and hands...

    Curious!! I think this is deliberate misinformation provided by (AI). For simplicity sake.DC motors use commutators to reverse the current direction every half cycle in order to produce back EMF. Induction motors induce a change in the magnetic field and that requires alternating current or AC...

    Magnifying tool for tiny circuit boards and surface mount?

    That would go against you correcting me. Not in your price range. "Inside every cynical person there's a disappointed idealist." -George Carlin

    Newbie needs help identifying/naming amber ribbon circuit

    Bravo! That's the way to go. There are safety measures or I should say a safety vent on the positive side of lithium ion cells they will melt at a lower temperature than euclidic 60/40 solder. There is solder wire that will melt at a lower temperature but why bother. Best case scenario safety...

    CAR KEY TRANSPONDER.

    There is plenty of information online. It would not be ethical for me to tell you how to hack the security system. I believe it is against the law, replicating and or bypassing security measures design specifically by the manufacturer of the vehicle. Your intention may not be malicious. Your...

    The screen/graphics card seems like it fade out or damaged. What may it cause and does it worth to repair?

    The screen/graphics card seems like it fade out or damaged. What may it cause and does it worth to repair?

    Very quickly ...Cold Cathode Fluorescent Lamp (CCFL). Your back light fluorescent lamp needs high voltage AC. The DC supply voltage to your laptop is transformed into AC by what is called an high voltage AC inverter transformer. For DIY hobbyist it would not be worth it for repair. But that is...

    Well dang nabbit! I don't know why? but after reading your post; I'm angry too. So here you go... Grumble Grumble Grumble. What is your price range? Are you only looking for spectacles... those things you wear on your head? Digital microscope with LCD display? How small of a surface mount...

    Newbie needs help identifying/naming amber ribbon circuit

    Almost got it. "Flex ribbon power cable" they look to be attached to the battery pack holder, they are offset connections. Your okay on soldering and desoldering those. Those Flex ribbon power cables are proprietary to DeWalt battery pack.. There's a reason why they have solder blobs on the...

    Comedy Thread

    Arizona bikers were riding South on the US-93 when they saw a girl about to jump off the Hoover Dam Bridge. So they stopped: George, their leader, a big burly man of 53, gets off his Harley, walks through a group of gawkers, past the State Trooper who was trying to talk her down off the railing...

    And now something weird

    Excitons [pronounced exit-tawn].are a key part of many technologies, including solar panels, photodetectors and sensors, as well as light-emitting diodes found in televisions and digital display screens. In most cases, the exciton pairs are bound by electrical, or electrostatic, forces, also...
