Just wanted the guy to see a picture. Mikek --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com |

I bought a coupld to use with a 100 MHz scope and can not tell much differance in them an a Tectronix probe rated for the same frequency range. That is why I said just cut off the end unless he has a bnc connector laying around he can just pigtail a couple of wires to. |

The benefit of a probe and coax cable/BNC connector is that one often works on hazardous voltages, and the probe is a safe handle to grab onto, even if the probe tip is on the 360V node... The best BNC-to-banana adapters for an oscilloscope, are the ones with a grounded shroud so the live wire isn't touchable. These used to be common, but now, not so much. Some oscilloscopes had a UHF connector and ground binding post, that are compatible with banana plugs; for those, a UHF-to-BNC adapter is the best way to proceed <http://www.banggood.com/Wholesale-BNC-Female-to-UHF-Male-PL-259-Coax-RF-Adapter-Connector-p-9234.html> < |

Maybe overkill to buy a modern probe and try to "hack" it to use on this old 'scope. Just use a set of conventional 4mm multimeter style test probes. The high frequency limitations of such a probe arrangement aren't a concern with this 'scope, which probably has a bandwidth of perhaps 500 kHz. I suppose the 1 meg input impedance might load down certain nodes in the Arduino, though... Here's another thought. One can often find a funtional dual-trace 50 meg or so 'scope with probes in the 50-75.00 range on eBay. Just a thought... Mark Z. |

Mains voltage rated PTCs are used in the AC supply to PSUs, both transformer and switchmode to provide anti-surge PLUS overload protection. Impressive to see one doing its job, running stinking hot while allowing only 25mA or so into the faulty PSU. .... Phil |

The main motor is a two pole induction one. The only one that I've ever seen with a single motor would have been 30 years old or more, and that had a weird rubber flap valve with a peg on it that was moved in one direction or the other by the impellor blades themselves. The valve opened the drain port when pushed one way and blocked it off when pushed the other. The problem with this arangement was that if debris held the flap away from the drain port, was that the machine would very slowly empty itself. -- Best Regards: Baron. |
