content: HiI just thought I'd update this thread. I contacted Kris about the function generator when the thread first came up - I've been looking for something in this line for a while. Although I was a bit hesitant about buying something from someone with no 'form', Kris couldn't have been more helpful - he sent me more photos and spoke to me on the phone. He came across as perfectly genuine, so I stumped up...I got the function generator today in the post - it was well packed and exactly as described. I've just had a quick play and it works very well. "Beauty".So, if you wanted anything else Kris had to offer, I'd say you could buy with confidence.(Now go and look at my "WTB" thread...)CheersJohn

I've got some cheap MAX7219CWG+ LED matrix driver ICs if you want - Page 1

content: I needed some LED matrix driver ICs for a hobby project a couple of months ago. So I managed to get hold of some MAX7219 chips (150+) left over from a UK production line for a relatively cheap price. These ICs are in SOIC 24pin package. They are in either cut tapes or antistatic tubes. I've tested and used 12 of them on my own LED matrix projects. They are working as they should be.Farnell UKis selling them for £8.97 in 1-9 off quantity. I'm offering them for £2.99 (1-9 pcs) £2.00 (10+ pcs) here. Postage by standard 1st class to UK is free. I'm not sure about postage to Europe, USA or the rest of the world, but it will be whatever the standard rate is charged by UK Post Office for your country.I also have a listing of this chip on eBay UK if you want to buy it just search for the chip on eBay and you will find it (no discount offered in listing, please contact me for an invoice if you buy more than 10).Here is the datasheet:http://www.farnell.com/datasheets/26306.pdfThe circle in the middle (bottom view) reads "malaysia 131"Please reply to the thread if you have any questions. Thanks for watching.

I simply have some chips physically available in the UK and want to share with people out there if they don't want to wait or spend £9 to buy a Farnell chip.

Electronics/techy/specialized online stores shipping from Hong Kong - Page 1

timestamp: July 03, 2012, 05:06:09 pm
content: I've bought my share of stuff from DealExtreme, and a handful of things from other sites, but I'm invariably disappointed in their stock. DX has a fair amount of LEDs and power supplies for the same, and lately they've added things like a few types of connectors and switches, but they lack discrete components and more, um, techy stuff in general. For instance I can't buy, say, large capacitors, or powerful motors (beyond the R/C model range), or individual flash memory chips.I'm looking for cheap sites that specialize exactly in the sort of techy stuff I want, but they absolutelymustship from Hong Kong -notfrom mainland China. The reason for this request is simple: where I live (Italy) HK mail typically arrives in 3-5 weeks untaxed, while Chinese mail arrives in as long as 3 months, and they often slap a hefty import tax on it as well. This has more to do with our third-world-quality post system than with that of the people shipping, but whatever the reason Chinese mail is to be avoided.Any suggestions?

Calibrating precision multimeter with some references I found - Page 1

author: tom66
author_rank: Super Contributor
timestamp: July 09, 2012, 10:49:03 pm
content: So, a while ago I bought a Solatron 7150plus faulty and fixed it, common line filter issue. It was last cal'd mid 2005 I think. So it's 7 years out of cal. It's rated to some ±0.004% on DC volts, 2.3V range.Whilst digging around in the "chips to be discarded" bin (oh the joys of being an intern) I found a tube of about 15qty precison 5V references (VRE3050B.) Not ±1%, or ±0.1% but ±0.016% (5V±0.8mV.)It's pretty close to the ±0.004% spec, at least the closest I'm going to easily get outside of a cal lab, so if I can just -verify- that it's within spec that would be reassuring.Only problem is they're in a weird SMD package but I *think* they are the same pitch as a DIP (& also very fat chip) so it might be a solder on the back of veroboard job.I'll see how it goes with using these chips... From a cursory look at a datasheet they want more than a 9V battery could provide so it may need to be a 12V PSU or dc-dc converter, or just a 12V battery.

timestamp: July 09, 2012, 11:06:45 pm
content: My guess is that the meter is probably less than 0.016 % off, so I would only use it for spot checks. It's not uncommon to find instruments of this class to be within 1 year tolerances on almost all ranges, even if the last calibration was 10+ years ago.Either Joe Geller (gellerlabs.com) or the guy behind VoltageStandard have published some documentation on how to build a voltage standard from an IC reference. Relevant issues may be mechanical stress, temperature gradients and thermal offset voltages.

From the looks of the listinghttp://nh.craigslist.org/tls/3077509061.htmlmost of the equipment is somewhat old but would be useful for a beginner like myself trying to setup a bench. The posting is rather vague in terms of model numbers but I was able to find them using the pictures. I was interested in:Insteck Function Generator $200 (GFG-8020H)http://www.gwinstek.com/en/product/productdetail.aspx?pid=5&mid=73&id=105Insteck Oscilloscope $250 (GOS-620)http://www.gwinstek.com/en/product/productdetail.aspx?pid=3&mid=6&id=75BK Precision Oscilloscope $150 (MODEL 1541A?)Shewzhen Mactch DC Power Supply $750 (HY3005F-3)http://www.amazon.com/Mastech-TRIPLE-LINEAR-SUPPLY-HY3005F-3/dp/B004ISD7T6The pricing seems rather high, however, I may be able to talk the seller down a bit. Does this equipment look OK, the scopes seem to have low bandwidth (should I go for a 100MHz scope?). I plan on purchasing a DSO in the future when I start working with digital circuits, but figured I'd get a CRO for analog circuits since there seems to be many recommendations to do so.

I don't really know what i should get for it, but I'm flexible in that regard.I don't know how to use it, but i have some pictures of the device turned on, please follow this linkhttps://picasaweb.google.com/108987705034973313443/Marconi?authkey=Gv1sRgCLGr5OjqjOKldQ#the fan is noisy, apart from that i can see nothing wrong with it, not that that tells a lotI have added a ebay auction for it, and as long i have no bids on it im flexible with the pricehttp://www.ebay.co.uk/itm/Marconi-2022-Signal-Generator-10-kHz-1-GHz?item=251084356339&cmd=ViewItem&_trksid=p5197.m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D5%26po%3DLVI%26ps%3D63%26clkid%3D9102038014815106399-lk

content: I have two of my own, thanks (one working and one in the "to fix" pile).However if you want a good price it's probably worth getting an N to BNC and demonstrating that the RF output works, not just that you can get 400Hz out of the mod in/out BNC (though I suppose that's something, at leastIdeally you need to demonstrate output in the 10kHz - 62.5MHz, 62.5-225MHz, 250-500MHz and 500-1000MHz bands as these are all generated in different ways. Even better would be to show the attenuator and AM & FM modulation working.

And then i will post pictures, but the timing of this all depends on what happens to my car.When hooked up to a spectrum analyser it put out a 900MHz signal when set at 900MHz, but I'm not allowed to take pictures in that lab, so you will have to take word for it-lk

Adapter to flip screen orientation! - Page 1

content: Ahoy! New member here!I am going to make a request for a product I don't if even exists. I'm looking for a DVI hardwareadapter of some kind to flip my PC screen orientation 180 degrees. I know this can be done with built in software, but I want to do it with a hardwareadapter. The adapter can be mounted anywhere along the cable, preferably around the screen input or so.For those interested in knowing why I want to do this with hardware:I am looking at three computer screens in portrait-mode right now. One of the screens has it's colors distorted because it is viewed from the "bottom-up" and the view angle is really bad from the "bottom-up" perspective. View angles from top-down, left and right are good. But bottom-up isn't. You could argue that I could just grab hold of my screen with my hands and flip it over, and then adjust the orientation with Windows built in software. But that is not possible in my case because of a AMD Eyefinity screen-setup, which interpretes all three screens as one single.

timestamp: June 03, 2012, 09:21:24 am
content: A Tektronix TDS500 or TDS700 should do it. These go down to 1mV per division and depending on the exact model they have a high resolution averaging mode (>10bit). Check the manual (downloadable from Tektronix) if a scope you have an eye on has peak-detect and high resolution. You should get at least an A model and be prepared to replace about 80 SMD electrolytic capacitors if the scope is from around 1990 because they have a problem with leaking capacitors. Later models (>1995) don't have this problem.
