I am not sure. Every old pickup I have owned has beed great and I miss them. Driving a new Colorado Diesel now. It is 4X4 cause where I live it comes in handy and thats about it. It has forward collision warning too. it does have a power driver seat and power windows, locks, back up cam, but thats about it. It still cost me 36K. Long way from our Mighty Max pickup! I remember out the door it was $7660 in 1987. We drove that thing for 5 years and they paid us $6000 when we traded it in! My dad just bought the one that was out in front of the dealership without really looking at it because our old diesel Oldsmobile wagon was such a piece of junk we actually left it running because if we turned it off we may not have been able to get it going again. Dad said I will take that one out there and the guy said it was an automatic and dad said whatever. Just sell it to me. We bought it, drove it for a week, took it back and had them add air to it. When we were trading it in the manager of the dealership did not believe we had a Mighty Max with air and automatic. He told us he already had a customer in mind for it and drove to our house in our new truck and brought his big dealer checkbook to cut us a check if our truck was legit. He told us he had a customer that had been waiting for a long long time for a truck just like ours had had a standing offer with him if he came across one. I bet its still chugging right along out there somewhere.

Predictable resonance - Page 1

content: Predictable, in the sense that I *should* have been able to predict it, but didn't.So, as part of a vacuum system setup I need an outlet exhaust pipe from the rotary pumps, to outside. About 6 m of tubing, not much flow rate, far end vents to atmosphere so there's virtually no pressure differential. Any old tubing will do, so long as it's large enough diameter to present no significant resistance, rigid enough to not kink flat on bends, and yet still flexible (since the gear can be moved around.) I'd settled on 18mm garden hose fittings for the quick-connects.Oh, and CHEAP. Of course. Yesterday at Bunnings the 18mm garden hose is far too rigid, and also nearly $40 for 10m. Turns out corrugated '22mm gray water' hose also fits the connectors, is very flexible, and only $10 for 10m. Yay! Just needs a little help with sealant at the joints.Luckily, when I got it home I happened to try blowing through it. Guess what?Turns out a long length of corrugated-wall tube makes a GREAT whistle. Weird sound and kind of cute, but I don't think I want the vacuum system to make this noise during pump-down.A short length of the tube doesn't whistle, so I suppose it's a turbulence resonance amplification thing, that builds up along the tube.Anyway, back to the tube hunting.

Makes a lovely noise source just taking a 1m long piece and swinging it around your head. Sorry Guy, either this or another hose with no step discontinuities, but what about old washing machine filling hoses, just need to join them with plastic couplers, or scrap plastic plumbing fittings.

content: I've been reading the glut of news reports of patent abuse, and I have to admit that I'm confused. Let me see if I understand this:1.) I invent a widget.2.) I manufacture said widget.3.) I, of course, charge for said manufactured widget.4.) I charge my customers patent royalties for buying and using said manufactured widget.It's the combination of #3 and #4 that confuse me. Let's use Qualcom as an example (and to be VERY clear, this is JUST an example, not a criticism of Qualcom!). They hold patents on various modem technologies and manufacture those modems. Cellphone manufacturers buy the chips from Qualcom and then Qualcom charges them a royalty on top of the payment already received? How is that legal, much less fair? I could understand Qualcom charging a royalty to, say Intel, for manufacturing a modem using Qualcom's patents, but how can they charge royalties for a device they manufacture and sell? Imagine Samsung or Apple charging owners of their cellphone products royalties on top of the retail price. There would be an armed mob at their headquarters.Am I getting this wrong?

content: A patent that you hold allows you to control whether other people can obtain commercial benefit from the invention that is protected by the patent.Thus, if you invent something and obtain a patent for it, then nobody else can make and sell something that makes use of your invention without your permission. You may choose to grant them permission, and you may charge them for that permission, which is what royalty fees are.Of course, if you simply make and sell widgets based on your own invention, then you just set the price according to the market. Royalties are irrelevant here, unless you need the rights to include some other invention in your widget, in which case you may have to pay royalties to a third party.

Since you are not in the supply chain, you do not have any opportunity to benefit from the manufacture or sale, unless you collect royalties.

Definitly not what a phone charger was meant for. Haha. Just testing to see how fast they charge as I noticed they were charging super slowly but just realized that it's because of my USB hub, so this was the first USB source of power I came across without having to make my own. Already put in 700ma into the 4 cells in like half an hour. Though I'm skeptical as I am pretty sure I had charged these not that long ago so not sure why they're so out of charge.

content: Just for fun, I flame sealed a 1ml syringe tube, then filled it with butane.While I was playing with the plastic tube, I noticed something.The liquid inside, then the bubble moves, creates a rippling effect, like these.Anyone knows why it happens? My theory is that since butane is a low viscosity liquid, and hence moves faster than water for the same tilting angle, therefore the fast moving liquid generates lower pressure (Bernoulli's principle). The lower pressure causes gas to form, joining the bubble. The force causes liquid to ripple.

timestamp: April 14, 2017, 12:51:25 am
content: I'm guessing what you're seeing is a wave being reflected off either the end of the tube or off the gas/liquid interface. Pretty much the same as a shorted termination in a length of coax or a reflection at a discontinuity. If you look at the troughs they look very regular and the wave amplitude looks to be bigger in the second picture as the reflection bounces back and reinforces the incoming wave.Oh and flame sealed? Filled with butane? I hope you still have your eyebrows left when you're finished.

Making a fake unit here means they can skip the steps involved in filling the things with gas and sealing, testing, etc. Use cheaper materials, skip the gas entirely, no expensive vacuum equipment or hermetic sealing required.Of course it poisons the whole well eventually. I've bought a lot of parts from China over the years and most of them have been just fine. Lately I've been screwed several times and I'm close to giving up entirely. At lease the used pull DSxxxx chips sold as new I can get a refund and hack a new battery into parts which are then free but I'd rather just know what I'm getting up front.

Turns out an employee at another location had recently been in our facility and had neglected to reset his default printer when he got back to his facility.Since this is a multinational corporation with interconnected offices, his laptop happily printed to the default printer once he re-connected it to the network. No idea what he intended to do with a few hundred b/w laser printed photos of feet, but he was terminated for that screw-up.

Digital television roll out in Australia has been a farce blocking any innovation from suppliers or consumers and perpetuating the status quo for the benefit of the commercial operators.

content: I can highly recommend a raspberry pi.If you have a TV that supports CEC, then grab a PI 3, 2 or 3 USB tv tuners, a USB hard disk and a copy of openelec.If your TV does not support CEC, grab an infra-red receiver for the same device and solder it to the GPIO pins as detailed in a thousand places across the net.Install the "tvheadend" back and front end, and bask in the glory of dead easy to use TV & PVR that records and plays everything and runs from either the remote on the TV (CEC), or a cheap MCE remote from E-bay (not CEC).If you really like it, spend the 2-something quid and buy the MPEG2 decoder license for the PI and get better playback.There are better and more complex configurations, but that is a great way to start and get hassle free "freeview" PVR level functionality. The multiple tuners means you can watch and record different channels simultaneously. It's all pretty well documented in the various wikis, and does the job.I have a telly in the bedroom and there was already a data-point there, but no antenna connections. So I used 2 Pi's. One in the lounge with some tuner sticks on it, and the PI in the bedroom to allow us to watch TV. Saved me dragging an antenna cable through the roof and cutting a new hole in the wall, plus the wife likes the ability to use the tvheadend client on the ipad to set up the PVR and watch stuff. Lots to like, and it works with all the current Australian free to air channels.

content: I was just looking at the spectrum here I could pick up from 2 to 1000 MHz. I'm using a ham antenna that is designed for 144 and 440 MHz, so take that into account. Lot's of signals here in the DFW metroplex (TX, USA).On the left of course we have the strongest signals in the FM broadcast band, among others. Then a large gap from about 220 to 470 MHz. At 470 we start more TV channels and then go to various services such as police and so on, and the cell phone bands. I'm interested in the large gap where not much is happening. I need to pull up a spectrum chart and see what is assigned there.Anyone else want to do the same scan from another part of the USA or another country? Use whatever antenna you can and we'll realize it's not optimized for all the frequencies.

content: I got some adapter boards for prototyping with an accelerometer and it's annoying QFN16 package - even ones with different dot pitch - then tinned the pads and used hot air to get it seated. No dice when trying to identify over I2C, then when I go to reseat it I realize the square packaged 16 pin chip uses a 5x3 pad arrangement rather than 4x4 and of course that wouldn't work when the chip is stuck downWell I got out the 28AWG wire wrap wire and the insulation was too thick to get straight runs to the pads and too springy to stay in place really easily... so I went for magnet wire. Pre tinned every wire and the pads (basically no extra solder beyond that), then went with the paste flux over the flux pen and finally managed to stick them all down. It works somehow... I'm not going to clean up the flux because I'm sure that will break a wire off... maybe just encase the whole mess in glue when I get some readings to verify it.For reference, the chip is 3mm on a side.

A case can be made for internet companies with astronomic IPOs/valuations, but it' very easy for these companies to start making large profits because of the relatively low capital requirements. The internet is a winner take all environment. Google&Facebook were already making fast increasing profits during their IPO.Trade on momentum if you dare, but don't be on the bottom of the pyramid when it all comes tumbling down.

I actually didn't even notice at first that these are not actually branded UltraFire although I did notice immediately that they're much too light to be real 18650 cells, and they're certainly nowhere near the 3800mAh they claim. I find it rather amusing that someone took the time to make a blatant knockoff of what is already a rather questionable brand, rather than simply copying the UltraFire label directly as so many other counterfeiters do.
