I have 4 or 5 of the 'Free' Harbor Freight metes. Verified them against a Fluke meter that was verified against some very high accurate lab gear. The HF meters are not that far off and work fine especially for a go/no go test. Does it really matter if the house voltage is 120 or 123 volts ? I have on in my truck and some in places around the house as I don't want to go the shop on the basement for a better meter. |

My HF meters are all pretty accurate, as long as the battery is fresh. My yellow ones do not have any low-battery indicator, so the only hint is when the readings do not make any sense (which may be a challenge for an inexperienced user). |

Take 'em back to Costco. Newer flashlights advertise "no parasitic drain". Get one that explicitly states that. Anything else is a crap shoot. |

"Arlen G. Holder" <arlingholder@nospam.net>: May 22 06:49AM Thanks to purposefully helpful suggestions by rbowman & Clare Snyder in this thread, we have five potential replacement free mail services to consider. Moving the on-topic potluck forward, I add value by reporting that I tested for the team the following five mail services, all of which seem to be potentially viable as Gmail replacements; however, my assessment is based only on _preliminary_ tests over the past couple of days only (where time will tell whether these five mail services are viable Google alternatives). o GMX <https://www.gmx.com/mail/> o Proton Mail <https://protonmail.com/> o Tutanota <https://tutanota.com/> o Yandex <https://mail.yandex.com/> o Zoho <https://www.zoho.com/mail/> GMX: o Unknown storage limit o Required Mr or Ms gender selection o Required a first & last name o Required a country, and, for the USA, a state o Required a DOB o Password must be at least 8 characters o Required a password-recovery selection (SMS or email) o Required a phone number for SMS verification (but didn't use it???) o Required captcha (easy fire-hydrant single-pass stuff) o Doesn't inform you the username is valid until late in the game Proton: o 500MB storage & 150 messages per day limit o Allows choice of domain (protonmail.com, protonmail.ch) o Recovery email is optional o Doesn't require gender or name or DOB or location or phone, etc. o Informs you in real time whether the username is taken or available o Password must be at least 6 characters o Choice of verification by captcha, email, sms, or donation o Captcha is easy one-pass fire-hydrant stuff o Asks to "show notifications" (which you can block or allow) Tutanota: o 1 GB limit o Doesn't require gender or name or DOB or location or phone, etc. o Requires a strong password of undetermined characters (at least 8) o Tells you the password cannot be reset (so choose wisely, I guess) o Informs you in real time whether the username is taken or available o Asks you to write down 64 hex character "recovery code" Yandex: o Unknown storage limit o Requires only first name & surname o Informs you in real time whether the username is taken or available o Requires a strong password of undetermined characters (at least 8) o Asks for telephone number but lets you skip in favor of security question o Allows you to write your own custom security question & custom answer o Requires a simple Captcha-like typing of screenshot words Zoho o 5GB storage limit o Requires only first name & last name o Username must be more than 6 characters o Password literally requires 8 letters even if it's much longer than that o Requires mobile phone number to send SMS verification code o Accepts free second-line mobile phone software SMS numbers though o Asks to enable 2FA but you can skip it "for now" o Save the numeric "user id" which shows up after you create the account If you have data to share to improve the quick summary above, or, if you know of _other_ free gmail service replacements, please let us know as Usenet is a potluck where everyone is expected to bring something of value to share. |

The Russian guy who wrote the EBookDroid app provides excellent customer service for an absolute pittance. We asked him how we could pay more (apparently paypal doesn't work in Russia), but he said just buy the 'pro' app. He also speaks (or at least writes) excellent English, such that I wonder if he's just pretending to be Russian. -- Cheers, Bev "Everyone ought to stop and smell crayons once in a while." -- DA |

The Russians are coming! Oddly I'm at the point where I trust the Russians more than our homegrown Stasi. I've been using Kaspersky on my Windows boxes for a long time. If it's stealing my data at least it doesn't let other people grab it. |

Replacements are available: > <https://www.ebay.com/sch/i.html?_nkw=7106+a%2Fd> Ok, thanks to all. I have checked the dual op-amp and the CD4070 and both is ok. I have checked the capacitor and resistor at pins 38, 39, 40 of 7106 (clock) and the values are correct, BUT if I power on the DMM without capacitor at pin 38 the display is perfect 00.0 without ghost segments (but obviously without any A/D conversion). This is a significant symptom? Replacing capacitor with another of same value (100p) make always display corrupted. I have 3 7106 and I checked with all, same problem. The display is mounted in a small PCB connected to main PCB through a flat plastic flexible "foil" with argent traces, pressed to pcbs with the plastic support of small display pcb. The resistence between every pin of 7106 and pads in small pcb is around 3 ohm. From small pcb to display there are classical siliconic conductive strips that I have carefully cleaned, together with plastic flexible foil. Where I can try to found the fault? Thanks. |

One thing I've encountered are many people who describe events that are obviously not explosions as explosions. Green plants absorb & use red & blue light. Green light, when growing, is wasted. NT |
