DS1052E Delayed Trigger Problem after Hack - Page 1

timestamp: October 14, 2011, 03:36:24 pm
content: Sorry to make my first post a question, but I've got a real problem: after I hacked my DS1052E to the 100Mhz DS1102E, the trigger delay no longer works.It locks onto a pulse and turning the HORZ knob moves the 'T' point and the pulse edge to the left. But just after I stop turning the knob, the pulse edge jumps back to the center. As far as I can tell this is the only problem.I've de-hacked the model and serial numbers back to the DS1052E but it doesn't help.

Save the post.The alternate way is to host the link elsewhere so you can put the link straight in.

Any good places to buy enclosures? (1/4 DIN car size) - Page 1

content: I'm working on a project which requires an enclosure in 1/4 din size, (90mm x 25mm and 50-100mm deep) but I'm having trouble finding any.1/4 DIN is a size used in cars for modules smaller than a full DIN (180x50mm ISO 7736). It enables you to fit 4 modules in one DIN slot. (two on top and another two next to them).Does anyone know of any available or know of any places that specialize in selling enclosures.I've already had a look on Digikey but can't find any cases that are 90x25mmProbably looking at buying 50 per year, so it's not worth having anything specially designed.

Ideal Multimeters with suicidal temp functions? - Page 1
Forum section: electronics / general

author: slipjointed
author_rank: Contributor
timestamp: October 11, 2011, 07:45:25 am
content: In the $100 meter shootout, I noticed a mention of non-working temp function on the ideal.I thought this was rather curious, as the thread I started about compact multimeters was due to the fact that my previous compact multimeter, an ideal, lost functionality on its temp setting after less than a year of very light use. It was quite surprising to me, as I only use the temp function occasionally. I have an Omega digital type K thermometer, but I don't like have to cart around extra gear unless I really need it, so I like to have a meter for my portable kit that includes temp.While I was hunting for a compact meter, I dug up some reviews on the little ideal I had, and to my surprise, I found two more reviews which mentioned a failed temperature function on the meter, or a failed temp function followed by outright failure.Four seperate accounts of temp function issues on ideal meters really makes me think they have a serious design flaw in their meters. I was also quite disturbed by the pitiful input protection on the meter Dave reviewed, but that's a bit off topic.The sad thing is, the overall physical construction of ideal's meters seems very good and I like the design (besides the silly bail on the one Dave reviewed), but it's pretty darned hard to trust any reading out of the meter, when ideal's engineers (or whoever they contracted) are putting out designs that can't even seem to read a type K thermocouple properly without self-destructing.Has anyone else here experienced this or heard of it second hand?

content: Given it used to work, its likely the actual components selected or the assembly process shortened its working life, otherwise the design seemed to be good. The costly meters suffer less from this kind of defect but it takes months to years of use to find out how durable they are, on cheaper meters durability issues could show itself far beyond the warranty period and now its not returnable.

content: yeah, sound like there is something intermittently wrong with your one.When i turn mine on, it always takes ~1.5 seconds to get to the rigol logo screen.For about half a second before that i get some random horizontal lines on the screen, then the rigol logo appears.Sometimes, if i turn it off then on again soon, the random lines are replaced by the previous image that was on the screen before i switched if off. So i think the lines/afterimage is just whatever is in video memory when its powered on.

content: The thing I have used that is similar is the Fluke 42XX range of precision voltage sources. You see them on Ebay for a few hundred dollars.What they are is a 4 quadrant power supply (Sink and Source positive and negative volts out). There is a range of preset current limits out.The outputs can be set to a specified voltage via a simple latched parallel input. Fluke did make a control panel, but it is pretty rare. It is not hard to make a useable control panel.There is also an external reference in that is multiplied by the value above - it may be optional, so some models may not have it.You can put an arbitrary AC waveform into the reference in, and you get it on the output. Frequency response and settling time is very good, so you could definitely use it with a conventional Arbitrary Waveform Generator.Output accuracy 0.01% and full of nice big Fluke precision wirewound resistors.Models came in BCD and Binary control. The half rack width units were (I think) 100mA output, and the full rack width models were 1A output. Two ranges - 0 to 16v and 0 to +/- 64V. (Even though directly the BCD units seem to only go to 9.999V, you could actually enter hex codes in, so you could get to 15.999V.)I think they sell relatively cheap since they have no front panel - control has to be done via the very simple parallel interface. For most people, they are a useless lump.I actually have one of the 4265A (Binary, 1A out) which I plan to set up - when I get the time. It is fully operational.Richard

Wanted to Learn Electrolosis - Page 1

content: Hello my name is Gary. I would really like to get into electrolosis because I’ve always found elctrolosis stuff cool. Like I seen little robots and small electrolosis projecs that i’ve always wanted to do but I dont know what exactly what I need to get started. I no ive heard on videos about a soddering iron, ill probably need to get one of those but I was thinking that since i have a plug in wood burner if i could use that? ive also thought it would be cool to make like my own tazer, but one that you can plug into the wall so its real high powered - does any one no of a good step by step for something like this. also where is the best place to buy sodder? I was at my local supermarket and they have a small, small hardware section but I noticed they carried sodder it came in a small tube though and it was quite expensive - $8. is there a better way to buy it, like in a big roll or something? the tube looked like it came with very little sodder. I went ahead and got it because i thought if i could get some help on here then i could sodder some small electrolosis strings together as practice tonite with my wood burner. I saved the little metal electrolosis string-things from a pair of broken earphones. I dont have two much money to spend on stuff, I barely bought the sodder because I thought it was a little pricey for the quantity. Back to what I was saying about the tazer, I think it would be really cool like if it could like shoot the electrolosis strings out kind of like the ones the police have, not the handheld kind like women cary in their purse.P.S. Look, its homer (8(l)

content: Building a tazer is probably not the best project to start on. If your calculations are incorrect you would probably kill whatever you shot it at which would not be good. Electrolysis is the wrong work I think you were after ElectronicsIf you are just looking for parts and stuff to play around with you could go to your local electronics repair shop and see what they are throwing out then pull the part off a board and see what you can make. Good solder will make work east the same as getting a temperature regulated soldering iron. Learning with a wood burner and crap solder can work but it will be hard. I use to solder with a lpg gas torch and solder that was way too thick which looks messy but worked.

content: I can't speak for ordering from Mouser, nor is my experience current, but in the past I found that UPS only charged brokerage fees on ground shipped packages. Once I found that out, if I had to use UPS, I would always use Next Day Air shipment which resulted in my only having to pay for the actual taxes and or duties. In my case, I was ordering SLR lenses, flash gear, flash meters and the like from New York. The cost turned out to be about the same for next day air with no brokerage fees vs regular ground shipping with all the so called fees added on. At least with Next Day Air, UPS has to give me decent shipping services for my money.Now, as for Mouser.... I would give them a call or catch someone on the live chat service they offer during business hours. I'm quite sure they have some sort of arrangement similar to Digikey which is also based in the US and ships via UPS without dinging the customer with brokerage charges. They may be set up as a non-resident importer and may charge GST/PST on your order up front so the package simply arrives at your door without hassle.Well, it wouldn't hurt to ask, anyway.RegardsChristian

Cost of implementing 6LoWPAN vs ZigBee? - Page 1

timestamp: September 29, 2011, 09:29:05 am
content: Hi.I'm not too familiar with how to test a product that I want to sell on the market. I guess I need EMC testing and CE marking...Say for example I want a product using 6lowpan, I use a transceiver like CC2520.What kind of approval of the product do I need before I manufacture them and sell them?Would it be more expensive to implement 6lowpan myself into a MCU and using a IEEE 802.15.4 transceiver, then to use an existing Zigbee module?(I guess the IEEE 802.15.4transceiver chip comes preprogrammed with an IEEE adress from the manufacturer)

content: The PR material from Microchip on their MRF24J40Mx modules (based on their MRF24J40 802.15.4 transceiver chip) suggests that a pre-certified module eliminates the need for any RF certification on your part. In Europe (and other jurisdictions) I think it's just a matter of self-certifying the rest. So if you're a small developer doing a small run it probably makes a lot of sense to integrate a pre-certified module rather than try to integrate a transceiver chip into your PCB design.Joe.
