content: HelloI'm starting to experiment with CMOS ICs, so I bought an anti-static mat and bracelet from my local electronics shop. They are theVelleman AS4 mat(surface resistivity 10e9 to 10e11 ohm/m2) andAS2 wrist strapwith 1 Mohm resistor.I didn't ask the shop guys how to connect and use them, thinking it would be obvious (silly me!) but the products don't have any manual. I just checked the Velleman site and I couldn't find any instructions there either.The mat only has one button, where you snap its own lead. I connected the other side to the ground pin of my scope, since it's always connected to earth ground, even when the instrument is turned off (I just verified it with my meter.) That leaves the wrist strap, which has another crocodile at the end of its lead.Is it ok to connect it to the edge of the mat, next to the other grounding lead, as I have seen in some videos and pictures online?Secondly, is there any hobbyist-level procedure (that doesn't involve buying expensive insulation testers) to measure or just validate an anti-static equipment setup? I just tried with my meter, but it can't read Gohm resistance. (It does read the Mohm of the bracelet, even between the grounding lead and the inside of the strap.)For instance, I'm considering buying these boxes, because they fit my preferences for part storage:http://www.ebay.co.uk/itm/221377178580But the brand and seller are such no-names, I'd like to verify that the boxes are actually anti-static before I buy several. Can I do that?

content: These need to be connected to ground. In the UK, this is done with a plug that exposes the earth (usually with some protection). The wrist strap and mat would then plug in to it.For testing them, there are go/no go testers used in companies to check anti-static equipment. I don't know how much they would be. These basically check that there is a some conductivity between earth and the user.

The stack is too deep and too opaque for generic embedded stuff IMHO.Plus with no source, no support contract, if something blows up, even with a checked build (which appears not to be available), debug symbols, windbg running remotely, most of it is just a bucket of hell waiting for you. GDB remote debug is marvelous in comparison. Hell even most of the build in kernel debugging stuff in linux is pretty nice. Oh it blew, backtrace, ahhhhhhhhhhhhh I see.

content: Hi All,I have just purchased and set up my China CNC 6040. Although Mach3 reports the X, Y and Z data is changing, none of the motors move. They are all correctly locked up when the power is turned on. I have tried a couple of old XP based PC's with standard parallel/printer ports so I think I am transmitting the data OK. I took the case off and can only assume that the yoocnc-450JKB (breakout) board has failed. Is there a simple way to test the output of my parallel/printer ports and generate test inputs to the 450JKB to check the motors move?CheersGary

content: Looks like it has a nice set of features for the money, and as it happens, is also sold as aX-tronic #4010-XTS(208 reviews & 33 questions you can read over).That said, although better rated than a lot of Chinese made stations, there are still some of the standard complaints that still plague them as a general rule (tips are crap, don't fit well, won't melt solder, ...). And since this one is more complicated than a simple knob type with LED display, it won't be as easily repairable should it break (i.e. loose the firmware if the uC goes kaput, and you may not be able to fix it). I did scan some of the reviews, but I'm not reading all of that.As you live in the US however, you have access to entry level stations from both Hakko (FX-888D)* and Weller (WES51) for just a bit more (free shipping over $75). They may be missing a feature or two, but the performance is proven. You get tips that fit, and in the case of Hakko in particular, probably the thickest iron plating of any name brand manufacturer.Something to think about at any rate (i.e. take your chances and gamble, or go with something proven).* Toss in a couple of tips to bring the order to $99, the shipping is free with this vendor.Also, if you go into your user profile and set your country, the flag will display beneath your userID. Makes it a lot easier for people to provide relevant links, and gets you information faster (no need to ask "where are you" all the time).

Quite nice though if you have them IME.As per the sleep function, that helps your wallet (helps make tips last longer), and auto-off can prevent fires being started from an unattended iron (especially useful with Chinese made stations as a general rule IMHO).FWIW, one of the consistent complaints I saw with the Amazon reviews of this station ^ was the handles fell apart and were uncomfortable to work with (too hot).

content: A little bit of fun looking at how cheap something can be produced, in this case a spinning top toy shown here in a youtube video:For those who dont immediately cringe when watching the video, its a Crazy Frog - Axel F loop, a song which made number 1 in the charts of many countrieshttp://en.wikipedia.org/wiki/Crazy_FrogThe casing is of an unmarked brittle plastic close to the thickness of a yoghurt pot, the poor quality leaving many stress concentrations from sharp corners which lead to this example cracking apart in use. The top spins on a small metal insert pressed into the bottom of the cone, and there are only 3 screws total.Before opening it there was conjecture as to how it was powered, guesses of a small flywheel generator or similar, however it is simply battery operated. There are two sets of 3 L1131 coin cells in series with the common low side (0V) switched through a collapsing spring accelerometer, one series string powers the laser through a series limiting resistor with 20mA, and the other string of batteries powers the LEDs and speaker circuitry with 60mA. The 3mm LEDs are put inside diffusers to make them the size of 5mm LEDs but less directional.Remember that all this is balanced into a spinning top.The wire attaching these parts is impressively thin, 5 strands of AWG40 (0.08mm diameter each) with plenty of loose strands left floating around inside the case.Stripping back to just the PCB, batteries, and speaker, I now have a convenient throwable noisemaker. And a pile of rubbish to dispose of.

content: http://www.frys.com/product/6517763It really sounds too good to be true, but it's the real deal. That translates into $3 for 10 USB power supplies and 10 USB to 30 pin cables. I tore down one of the power supplies and it's pretty well made with a proper switchmode controller IC and plenty of insulation tape. Even more surprising is that with a 1A load, the output voltage actually rises a little to 5.15V (from a near perfect 5V), as if to compensate for cable resistance. It does heat up with a 1A load, but no more than other good quality USB power supplies. The cables are nice and thick, too.(There were two additional pieces of insulation tape between the sections, which I removed for the photo.)

So there is no problem with the electric load.And there is no change if I use 100mA or 1A load.I did a video of the problem.https://youtu.be/GIKHLfaEOWwI do not know if this is within USB specifications or if it's defect?I haven't used it with any of my electronics.I am not so sure I like to connected to my Sony tablet ?toughs ?Anyone

content: This might be some Accucell-6 quirk. I think it ramps up the load smoothly at startup (at least I think mine does) and chances are, there's some voltage being coupled from it before it actually starts to draw any current. Have you tried with some passive load?

content: "Safety certifiation" doesn't make something "safe". And lack of official safety certification doesn't make something "un-safe".If you are installing this is a public place (or somewhere you don't live like a rental property, etc.), or if you are worried about your fire insurance, then don't buy dirt-cheap goods from China on Ebay. And perhaps in your country licensed electricians are prohibited from intalling non-certified components.Would I install one of those in my house? Probably. It looks rather well designed and assembled and I am a DIY geek.

Link to the thing on Pace's site is at:https://www.paceworldwide.com/products/handpieces/tweezers/tt65-thermotweez-sensatempNow, the tips average nearly £50 UK Sterling a pair, see:https://www.paceworldwide.com/products/tips-and-nozzles/tweezer-tips/tt65-thermotweez-tipsI have a decent metal fabrication set up as I do race car work, I am wondering if anyone has ever tried making their own tips? It LOOKS like the solid (copper?) rods are riveted to the folded sheet grip parts of the tips. I am thinking of finding the OD of the round bar that goes into the tweezers and buying something that's either the same OD or can be turned down and TIG welding folded copper sheet using TIG brazing the folded bits to the bar. Or even attaching the sheet metal parts by the use of copper screws?These tips are presumably copper, but what is the plating made of, and is it vital, for occasional use, that they *ARE* plated, or would regular tinning with solder and cleaning do for my purposes?I know time is money, but I would wince at £50 a pop for new tips....Thanks!

They're a full 1 foot in depth and made of nice see-through plastic with decent thickness (doesn't feel flimsy).The horizontal version has three drawers, and the vertical one four (plus the horizontal one stacks).Anyhow just thought I'd mention this in case it's of any use to others; I'm gonna go back and grab a few more. Not sure if they carry these normally or not; they are listed on this weekend's "special buy".https://www.aldi.com.au/en/special-buys/special-buys-sat-2-may/saturday-detail-wk-18/ps/p/coffee-pod-storer/

They are also a good fit for the standard 3Doodler filament segments.
