Gents real interesting thread! My thanks to Matt, nepp and lab insight from fechter... I've been fighting the same demon for over 35 years... I hope this thread continues, and we continue to learn things. One thing I would like to share. I was a member of "mended hearts" as was my WWII nurse mother....

jonyjoe your solution is a good one, and something I was going to mention. In the aerospace sector (where I spent my career) we always did FMECA (Failure Modes Effects and Critically Analysis) and used concepts of single failure tolerant and two failure tolerant to protect life threatening critical ...

As mentioned above, don't underestimate the post sales support required. It can eat you alive. Then when you are overwhelmed, folks will start complaining about no timely response. May I recommend that you set up a Message Board for your company. Have it up and running before sales start. Point peop...

Early on the thread spoke of vitamin supplements. Thought I would share my journey over the winter with a kidney and 8 bladder stones... About two years ago, I thought I would start taking vitamin C regularly. A good antioxidant and supposedly helps prevent colds and such. A older (75 years) friend ...

Nice track Amber, real nice!

The key ingredient you are looking for is a grease containing Molybdenum disulfide, or "moly". Some alternatives: (your recommended grease was a NLGI 1 a thinner version. It is a bit harder to find than the thicker NLGI 2. The thinner grease is better with gears as it tends to flow back into the cre...

Thanks fecthter, I found out the connector is off a Koyo designed power steering unit, so perhaps it is a Japanese sourced connector and GM had to pick up what Koyo sourced. Weird. epowersteering found the source as they offer the connector with two crimp terminals for $5 bucks. If you can believe i...

Thanks gents, yes, I got the pix from epower steering. If GM uses these connectors with a 50 amp fuse in a safety critical function (steering) there must be something good in the design.

I couldn't find a manufacturer match. Strange for GM connector...

I ran across a picture of this connector series. It is being used commercially for 50 to 75 amps continuous. The spade connectors are about 10 mm wide. I spent about 4 hours today trying to find it... with no luck. I found a picture of the terminals in a china site, but no match to anything "real" o...

These are the threads I wait to savor!

However, wish it didn't say "has 128 bit AES encryption" ... hope they didn't encrypt the data stream...

It's inrush. If you want to stay mechanical, I have used these definite purpose contactors from Automation Direct. Not too bad for imports and the price is pretty good. https://www.automationdirect.com/adc/sh ... contactors

Pure genius the SRPM architecture. Great efficiency gain when a large portion of use is at part load. Saves on rare earth materials. The person who thought of this marriage of technologies has paved the way forward with a giant step. Thanks for the insight on losses Luke.

Thanks Bill! Great write up and great information!

Since there are knowledgeable pilots on this thread, let me ask this question: Early on, they stated how the 737 max engines could provide "lift." Well to me that was happening because they possibly installed the new engines with a positive tilt upwards, that bought more clearance for the nacelle wi...

Good write up quoted by the OP. Looks pretty consistent with all I've read to date in a condensed form.

This gent is pretty good with facts. He flies right seat in 777 and is about the facts, not emotional diatribe. A good reporter. https://www.youtube.com/user/blancolirio/videos

First, wondering what Justin's thoughts are? Second, not a supporter of FB. More and more of it's security flaws are going to be exposed, and I think it is near the top of its curve right now. Third, a conservative, planned migration to the next generation message board engine may be a consideration...

... I can't figure out what his endgame is. His approach doesn't really make sense if the goal is to monetize a scam invention. Unless he really does think it works; he may be able to delude himself sufficiently to keep that belief alive. Very possible a small group of ol' guys with a little dement...

An update on this one too. You can't find a better magnetometer, but It appears it was too pricey. Now willing to sell at a loss at $899 plus UPS shipping. It is still up on the auction site we all know and love. Meter and probe are calibrated and ready to rock and roll.

I'm going to throw up an update on these. I have sold two of them for $279 and only have one left. If anyone in the USA is interested, will sell for $279 plus UPS shipping costs. If you want to make an offer do so. These are rock solid 750 watt all day electronic loads.

Amazing as it may seem, Rossi is still at it and still getting money from investors. Yep I watched it all and couldn't believe it. The echo from a perhaps empty garage, and perhaps three people on chairs and a bare concrete floor (because of the echo). He kept talking about the "dancing ballerina" ...

I have three headbands with the flip down lenses in 1.5 2.5 and 3.5 power. For surface mount PCB work a stereo microscope with Barlow lens. ... and LOTS of light. It seems I am adding lighting above my bench with every 5 years of age.

Here is what I do for broken screws/bolts on really expensive things. It takes a mill (Bridgeport) however, but you may be able to adapt. Lock the part down on the table with fixturing. Take an end cutting end mill and make the top of the broken screw perfectly flat Use a center drill and your skill...

Thank you for all the info, going with all the info I am going to ask ddk on his thread to get more accurate info, as I have doubts the 2 pole can handle 30A :shock: ... Note the specified 3mOhm contact resistance. At 30 amps that 2.7 watt dissipation per contact, or 5.4 watts per 2 pole connector....

Always an pleasure and honor to see you Bigmoose. Most of the decision maker position folks at these companies are ICE/Hybrid legacy mindset folks who viewed EVs as the burdensome and financially costly compliance requirement to sell their gas cars into California. If you have two boats, you might ...

Its not about vision but about Return On Investment. The european market and mindset is very different than the USA. Its all about the distances and population density. I'm a rural guy in the USA. Always have been, and Lord willing, always will be. I live where there is 3 months of that white stuff ...
