Re: Mind-Blowing Ebay Electronics Deals

YIKES! You guys are very brave for going that route! :shock: Sometimes there is a slim difference between brave and stupid ... ...and far be it from me to define where that difference lies. :D Much as I like electronics and all that (see below for another hobby of mine) I'm not one who thinks that ...

Re: Mind-Blowing Ebay Electronics Deals

The Colorado Live Steamers is implementing a signaling system based on RFID readers, XBee radios (running Digimesh) and Arduino micro controllers. (Please don't ask me why we are using RFID readers ... that decision was made long before I got involved.)... YIKES! You guys are very brave for going t...

Re: Mind-Blowing Ebay Electronics Deals

As you know if you're doing this for a living, typical cheap-resistor tolerances are 10% and even higher, and they work just fine in products found all over the world. I don't care at all if my 1/2-cent 1% resistor is off by 10%. I was shopping for 10% resistors when I went to Ebay in the first pla...

Re: Mind-Blowing Ebay Electronics Deals

And if you work with Arduino or Blue Berry you can buy knock offs of them and any peripheral card that you want for pennies that mimic the real thing using the 'real thing' software to program them. It's like Trump says - "China is eating our lunch". China wouldn't be "eating our lunch" if cheapska...

Mind-Blowing Ebay Electronics Deals

I do electronics professionally (see below pic for an example) and would NEVER purchase anything from an eBay seller unless I knew the origins of what they are selling. Electronics counterfeiting is a huge, world-wide problem, and the majority of the counterfeit crap emanates from communist China. I...

Re: One Type of Air Connector Better Than Others?

Sort of like the size of a 2x4; they just aren't 2"x4" Adding to the confusion, the 2×4 has undergone several size changes over the years. Long, long ago, a 2 × 4 was really 2 inches by 4 inches. However, that was rough lumber with no finishing beyond sawing. After planing, the finished product was...

Re: Red Arc

Red eyes from staying out real late the night before? :lol: The electrode type can influence the color of the arc, plus there is some reflection from the puddle. Absent the above causes and assuming you are using a helmet lens that uniformly impedes the entire spectrum (including ultraviolet radiati...

Re: Never enough time

And I thought it was just the diabetes causing the cold feet. That's a good part of it. Blood flow through the small capillaries in the feet isn't what it was before diabetes set in. Your feet are radiating heat at their usual rate, but not enough warm blood is flooding the tissues to replace the l...

Re: Super Heater Return Bends

Possibly the following will provide some useful background for our discussion on stainless steel(S/S) super heater tubes. The most common S/S rigid tubing available is either SAE 304 or 316. 316 has a little higher resistance to flaking than 304, but, is tougher to machine and form. Otherwise the m...

Re: Never enough time

I'm 77 and wear a size 12D. Big feet for a short guy (5'-10"). I'm a few years younger than you, but about the same height. Feet are smaller though. Your shoes are gunboats, mine are rowboats. :lol: I'm all too familiar with cold feet and getting old. I don't remember it being like this when I was ...

Re: One Type of Air Connector Better Than Others?

My dad's couplings were automotive, so when I bought some new ones recently, that's what I went with. But I also made an adapter so I could use rental tools with industrial connectors. By "industrial connectors," are you referring to this style? truflate_male.png I think Tru-Flate' is considered on...
