It's perfect for limited runs. What gets me is the price of the extraction tool. They want $ 42 for a piece of steel that probably cost less than a dime and maybe after tooling and design work a few bucks. I would think that $ 5 would be more than a fair price for those. |

A required characteristic of 3D printing is that the plastic material involved must melt when heated. That would be really bad for a connector body. That has already happened in the RC (radio control) XT-60 power connector area: <https://www.google.com/search?q=xt60+connector&tbm=isch> Most of them are made from molded nylon, which doesn't melt when heated by soldering iron. However, some 3D printed ABS clones of these connectors melts when soldered. -- Jeff Liebermann jeffl@cruzio.com PO Box 272 http://www.LearnByDestroying.com Ben Lomond CA 95005-0272 Skype: JeffLiebermann AE6KS 831-336-2558 |

Chack for similar parts with different mfring locations, finish, base metal, insulation diameter range or type of physical delivery (eg chain-feed). digikey hasn't been particularly savvy when it comes to old part number discontinue notices, recently. Could even be a mfrs new catalog typo. Have seen same thing with Amphenol - complete bullshit if you're just looking for something that has form, fit and function. RL |

I wrote that 24 years ago. I haven't really re-read the story, until today. All I see are spelling errors, things I left out, and some awful Hebrew to English transliteration. Over the years, various readers have suggested changes, offered additions, and translated it into Hebrew, Yiddish, and Polish. In its day (1997), it was something rather unique for Usenet. Today, with the addition of a far better writers to the internet, it's rather mediocre and commonplace. Oh well.

"Peter W." <peterwieck33@gmail.com>: Jan 03 11:38AM -0800 Unless one is focused on increasing landfill, or way-the-hell out in the boonies and so off the grid, or the locations are very far from any source of mains power (such as in orbit), I can see no reason for solar-powered (or even wind powered) lights. These devices are very popular in our neighborhood, everything from the little stick-in-the-ground lights to the devices similar to what was linked. However, I have _NEVER_ seen one of these devices last more than a year, mostly only a few months. Cheap cells, cheap batteries, cheap electronics, cheap housings and normal mid-Atlantic weather chews them up and spits them out. If one must have low-voltage, go for a transformer-served system - our next-door neighbor has such a system that has been in place now for over 6 years without a failure. Otherwise, take the trouble and install a mains-powered system. Some other observations: a) Exterior lights - most especially those on motion-sensors - will not protect one from criminals. First, most of them operate by daylight - complete with uniforms, marked trucks and clip-boards - know that you are not at home, and know exactly what they are doing. They will be in and out in less than 10 minutes mostly 5 minutes or less. b) And should you have that unique night-time burglar, all you are doing is giving them light to work - remember, they KNOW that you are not home already. c) Overall in the United States, only 14% of all burglaries are home invasions - that is the breaking in to an occupied house. Of those the majority are seeking confrontation, usually related to drugs, and they usually know their victims. However, those home-invasions tend to be incredibly violent, and seldom motivated by simple greed. d) The average police response time in the US by location is over five full minutes from the time called. So, an alarm system notifies a security company, which in turn attempts to reach the owner, and then only dispatches the police. So, ask yourself: a) All sorts of lights at a cost and of dubious utility? b) A loud, but well-trained dog? Size does not matter. c) A shotgun with some basic training in its use, and a strong dose of common sense so that someone dropping in on a surprise visit is not damaged? d) A burglar alarm system - knowing that the most useful part of it is the sign outside? Aside: Alarm systems that are tied to smoke and heat detectors do have a function in the protection of real-estate. Otherwise, not really, again other than the sign. Hand guns are long guns are neither legitimate nor very useful for home defense other than perhaps as a club. Peter Wieck Melrose Park, PA |
