content: I normally wouldn't post something like this, but I have been so impressed with this particular eBay seller that I felt I needed to share.Link to store:http://stores.ebay.com/experimentersdiscountwarehouse/I found this vendor a few months ago, and have now purchased from him 4 times.Components come individually bagged and are labeled with the eBay auction ID and your eBay username.Here are a few items from my most recent order:The prices are great and he combines shipping, which has resulted in some binge-purchasing on my part. I'm bad like thatAnyways, I am not affiliated with this vendor in any way. I am just a happy customer.Look through his listings, and you might find some parts for your next project.Edit:Just noticed the warning at the top of his page "Our advice: Resist the urge to stockpile. Buy what you need today. Build your prototype first. There's always more surplus!" oops...

First meters - Page 1

content: Over under a cheap multimeter thread I posted about my first meter being the really cheap Radio Shack analog one - the tiny pocket size one with the blue case. Well, I suppose you could say that was the first one that was truly mine, as in I bought and paid for it, but the first meter I had use of was actually one of these:eBay auction: #http://www.ebay.com/itm/Conar-Appliance-tester-model-200-with-Leads-and-Manuel-/262256537297?hash=item3d0fb52ed1:g:1QIAAOSwwbdWK-wp(not my auction, don't know this person)The only difference was the one I had was branded NRI - my Dad at some point took their correspondence course in appliance repair. Mid 50's I would guess, after he got out of the navy. This thing was insane - there was a plug, so you could then plug a device in that outlet on the front and measure amps, and check the line voltage, then it also had the probes and an ohms setting. Power for the ohmmeter came from a D cell battery SOLDERED IN - there was a battery holder clip but no power connections, just two wires soldered right to the battery terminals. I discovered this, and also all the books from the course, which I read cover to cover, though they were woefully out of date, sometime in the early 70's.Anyone else ever see one of these beauties? Sadly I no longer have it, that soldered in D cell leaked all over the insides and made a mess, plus the line cord was one of those rubber covered types which dried out and cracked.

Solar charging carbon/alkaline batteries - Page 1

content: Disclaimer: I did no research!I have a friend with one of those super cheap aliexpress solar garden light things. It doesn't hold a charge any more. She wants to replace the battery. I don't think it's worth it.Anyway, I was wondering what effect the super low charge rate of one of these things would have on a disposable battery. I suspect little benefit, but no harm.Any thoughts?

author: CatalinaWOW
author_rank: Super Contributor
timestamp: February 02, 2016, 03:26:48 am
content: Replacement batteries for these things are widely available, and if you shop around fairly reasonably priced. If the housing isn't deteriorated by sun exposure (including the solar cell window) it is well worth replacing the battery.Standard disposable batteries will accept little or no charge, and since the light only comes on when it is dark out the solar cell will not reduce the load on the battery. So you will have converted a solar garden light into an expensive battery holder. It does have the features of a low current light source and turn off during the daylight hours which will extend battery life over an always on situation.

content: Just had a quick read of the EDRS system on the BBC websitehttp://www.bbc.co.uk/news/science-environment-35446894I'm really interested in how these satelittes establish the lin in the first place. The laser on one (I assume) moving satelite has to hit the one communicating with the base station that is in a higher geo stationery orbit. I wonder how they find each other? There must be some initial GPS location work being done to get a to an approximate distance. Just thinking out loud. What are your thoughts on how they might achive this?

author: SeanB
author_rank: Super Contributor
timestamp: January 31, 2016, 02:58:39 pm
content: At a rough guess you are right, use a combination of GPS and then star tracker to align the laser roughly, then simply rely on the beam being wide enough to achieve lock on the target, and use fine pointing to drop power down and do a better alignment job. Probably uses a broad beam or series of them so as to cover the rough plane of the constellation for a return path, rather than trying to track all at once, using a simpler method as you can have higher power and easier aim to multiple receivers rather than point to point comms. You only need a low data rate for control, the high rate is on the imaging side, not control and housekeeping, which can run over something approaching dial up data rates for the most case.

Looks like there are still plenty of idiots who believe in "reefer madness" (complete with the mandatory reems of black people smoking it)Given a fucking good chance to legalise a simple literal weed that grows everywhere on the planet, somehow religious legislation > nature.Personally I fucking hate imbibing the stuff. I've tried SO MANY times to enjoy it, but I am always left feeling ill with a "Whitey". You know what? Just because I don't like it doesn't mean I wish to ban it for everyone else on the planet. That would be like I was the new arrogant shit like Mohammed or something.Carl Sagan was a famous toker. Better than alcohol, heroin, or religion I would say.

Give them some alcohol and, yes, I have been a bloodied and black eyed victim of their ignorance and intolerance.(PS. I am of course lamenting after a few cans of lager before retiring to bed)

If that's so, someone could potentially be unpleasantly surprised if they are expecting licenses for those options.It should be noted that Keysight does offer an "ultimate scope" option package for this class of scope, so it's not unreasonable to expect that what was done here.Perhaps it's possible this is a legitimate demo scope with some kind of a demo mode enabled.

It's been running for a little while and the test is just to measure the temp rise and check all is OK with it. So far so good.So it's sitting on my left about half way down the bench working away, I am on the computer at the end of the office. Now I need to check something at the other end of the bench, so I simply push my chair backwards (t's on castors) to slide to the other end of the office, as I do many times a day (it's a small office). As the chair rolls over a sheet of bubble wrap on the floor, the loud fast popping sound has be diving for the bench PSU powering my board thinking it has just failed in a very spectacular way.I almost made it to the bench PSU too, now have to tidy up everything I knocked over on the way down.Now the adrenaline is returning to normal, I feel the need for more tea.So, be warned people, bubblewrap is dangerous...
