content: (With apologies to the Marx brothers for the quote)I was at my parents' earlier, sorting some Christmas stuff, when my dad tried to use his (major brand) battery charger to recharge some AA cells. Nothing was coming out, not a pico Ampere Hour (see what I did there). Dad is more than capable of fixing it, but he was busy so I said I would take a look.To cut a long story short, nothing obvious was faulty. No smell, no burnt PCB, and the solder joints were as ok as anything lead-free ever looks. The input transformer metered ok for resistance on primary and secondaries so I plugged it in to measure some voltages. Wouldn't you just know it - it worked fine. Anyway, never one to look a gift horse in the mouth, I cased it back up. Before handing it back, I plugged it in and - yeah, you guessed it, - it didn't work again. Anyway, I did some metering. Nothing on the secondaries, nothing on the primaries. In fact, nothing on the input wires. Not a sausage. Strange. Much scratching of head ensued.And then I noticed something. The Christmas tree lights are on the same extension block. And they were off. They were on five minutes ago when I checked the charger. Yes, you guessed it, That circuit is on a timer!I could have got carried away for hours there. I thought I knew that the mains supply was fine, after all I had just checked it. So the moral of this story is one of the first things I learned as a kid when fixing stuff for mates, and the thing that Dave keeps saying: DO YOUR SANITY CHECKS!I'm not one for Political Correctness, and I hate calling it "the holidays" so I'm just going to say happy Christmas everyone, and I hope yours is peaceful / quiet / exciting / thrilling / relaxing / fruitful / interesting (delete as appropriate).

content: Great story. I once went to my grandfathers house to figure out why a ceiling light wasn't working. Checked the circuit breaker, ohmed the bulb out,etc... Come to find out, it was on a three way switch and the switch behind some boxes was in some middle position preventing the circuit from functioning. His ego was slightly hurt. Haha.My dad speaks about being flown out to some company to figure out why the assembly line shut down. Someone had pressed the e-stop.Also not one for political correctness, Merry Christmas and happy new year to everyone and their families.

I would produce the graphics in a real graphics/graphing package and import the image in Word. If Word screws up, I can just re-import the image. I only trust Word with simple stuff like letters. I may grudgingly accept using Word for a report if mandated by somebody like my boss, but I would make sure I could rebuild the document from text and external graphics within a reasonable time span.

Supposing I wanted to buy more connectors like this one that will plug into the same socket, is there any hope of identifying it? Do connectors come in standard shapes, or is the world full of proprietary designs all different with little hope of finding a match? I've looked at Molex connectors and it doesn't seem to be one of those.Does anyone recognize the general design, or is it just "some random connector"?

Electronic load considerations / PSU testing - Page 1

timestamp: December 14, 2011, 01:27:37 pm
content: Hi all,I need to test a variety of power supply circuits at home and I am considering purchasing a bench-size programmable electronic load. Typical power supplies might exceed 300VDC at a few mA. On the other hand some low voltage supplies are in the 1.8-48VDC range at a few amps. Overall, I dont have an immediate need for anything above 150W. I will be needing a constant power and constant current modes, with constant resistance being useful (depending on response time).There are a few China-made candidates on ebay and rebrands of those. However, keeping all options open, what other specifications would you be looking at when searching for an electronic load? I wont be doing any testing of PV panels, so I cant see the minimum input voltage as a function of current being a high priority factor. Budget is about $500.Any input/ideas much appreciated.

content: It won't do anywhere near your HV side, but this,http://uk.farnell.com/jsp/search/productdetail.jsp?SKU=1799872will do up to 60V, 150W. I have one of these at work, the user interface takes a little getting used to as it's shoehorned into a PSU enclosure, but it works well. It also has a very good step response which can be an issue if you look at turn on characteristics, especially of switch modes. With a 10ms pulsed load (external FET switching load into circuit, at 0.9 ohms load, 5V supply) this one responds in less than 0.2ms.Other than that, some of the cheaper ones are exceedingly loud, and I have heard of some that have a rather high TC-never come across one myself though

Outboard preamp/prescaler for counters? - Page 1

content: Has anyone seen an outboard preamp and prescaler for counters? I'm particularly looking for something in the 200MHz-1.5GHz+ range for my 5335A. I guess I could build a simple 10:1 out of an MC12080 but I was wondering if their was anything commercial with a good amp/buffer in place.

content: Tektronix made some prescaler modules for use with counters although I don't know if they are common on ebay or not. It scales the signal down by 16. Maybe you can use the scale (multiply) function of the 5335A to scale the frequency appropriately so you can read the display directly. Or use it like it's supposed to be used.http://www.barrytech.com/tektronix/tektm500/tekdp501.htmlThis one might also be worth reading:http://ve2zaz.net/hp5328a/hp5328a_prescaler.htm

I decided to look to see if there was anything else and ran across a program called Soft48 which is a program written to copy some of the usefulness of an HP48 but not outright copy it. I went to the author's page and he has a number of personal opinion pages and some interesting information. Then I encountered a link that went to photos of his trip to Chile. I finally ended up looking at a photo taken only 100m from my house at my neighbor's during the person's visit here for an astronomy tour. This is the very business that I help conduct astronomy tours most nights.This is the kind of thing that would make most people believe in woo woo stuff. For me it just shows how small the world really is.

A second later I looked at the in-box and saw the tragic news, a friend of mine was just killed in a canyon.Now the coincidences start:1) I uploaded the calendar at almost the exact same time I got the news2) The photo on the December page was of the same canyon he died in, in the same month.3) The photo showed another friend of mine in the exact same location as where he died4) The photo showed the exact same seated position of how he died, with the water flowing over him, holding onto the exact same rope, facing the same way. The only difference was the person in the photo.5) My friend didn't normally take that route were he was killed, and only started taking it after I was on trip with him once where I said the jump he normally did was dangerous and he'd land on a submerged rock. To prove I was wrong, he jumped, and hit the rock I mentioned and tore all the tendons in his foot. Since then he took the alternative route where he was killed.Scary...Dave.

content: Hey, I'm having trouble finding a matching pot and encoder for the front panel of something i'm building.I'm going to make the units in bulk, so dirty tricks of mounting things half off the pcb to compensate for size issues isn't practical.They really have to match properly so they are easy to assembleAre there any better places to look for pots/encoders than digikey?egThey need to match in terms of- Shaft height from pcb if right angle (so both end up at matching height) -or- total height if vertical mount (so the top panel sits flat across both pot and encoder)- Shaft length/diameter- Shaft type, (slotted, rounded, flattend, knurled etc)- Threaded section for typical mounting nutI'm also having trouble finding a good selection of matching knobs to pick for the encoder and pot.The pot knob needs an indicator arrow (or line) but the encoder knob should be blank on top.About 90 percent of the knobs i find look really old fashioned.Also the digikey knobs are mostly imperial sizes while the digikey encoders are mostly metric.It all seems to be a lot harder than it really should be.Does anyone have any tips for finding and buying pots, encoders + knobs for them?Thanks

content: Indeed, it would be unrealistic and quite difficult to find a physically matching set between two different vendors of specialized components with non-standard packaging for self-evident reasons. Without going custom spec, your best bet it probably cross-referencing individual vendor websites directly. If you haven't already checked, Alps (www.alps.com) might be a good starting point as they manufacture both pots and encoders.Nevertheless, it sounds like you're looking for a custom-spec solution without the custom-spec price tag...which is asymptotic to having your cake and eating it too.
