Especially when working with lead-free solder, on account of the more aggressive flux used.I bought one of these almost three years ago, never regretted a single cent I spent on it.

content: I have a Scope ETC 60L-1 65W single channel station made in Australia which I've owned and used since 1991. However, t's not been used for the last few years although it is a very good station it needs a new hand piece. I want to give this to a nephew of mine but I've not been able to get a replacement hand piece (I've tried Scope and their suppliers).The hand piece from memory is similar to the Hakko 926 but the plug is female (Station has a male plug) which is the reverse of the Hakko 926. Anyone else here have one of these old Scope stations (or is familiar with them) and know of any compatible hand pieces. I'm sure one of the Hakko clone hand pieces will probably work, just don't want to buy a dozen different hand pieces to find one that works.These are really good quality stations and I would much rather get a new hand piece and give it to my nephew than spend the same money on a budget station for him.

They didn't.That being said, for $13 bucks, the first light is quite impressive. I haven't opened this one yet because It works brilliantly and It's currently hanging on a theatrical fly bar. It is quite responsive with sound activation, clapping or the beat of the music teigger the various effects quite nicely. I'll see if i can get a video of it.Now here's the interesting part, the second one, identical packaging, came in the same shipping bag, itcompletely differentUpon teardown I found out that the second one:-the main light (RGB, 3x1W led) were all wired in series on this board, and were powered by a seperate rectifier/transformer assembly than the bottom board.-The bottom board has what on first inspection is a PIC style 8 pin mcu. This one cycles through a very small amount of effects, and they forgot to code in the blue LEDs! I still have to find some of the traces but it appears to be using a tri-state configuration.For about the same price as a lotto ticket, you can something far more interestinghttp://pages.ebay.com/link/?nav=item.view&id=131645212463&alt=webOh yeah, that second one, the one that sucks, has no facility for audio activation (there is no mirophone...)
Soldering Microcope - Barlow lens and lens protection advice - Page 1

timestamp: April 13, 2016, 04:14:00 am
content: After much looking around I've just ordered one of these microscopes (despite the horrendous USA --> Australia shipping fee!)http://www.amscope.com/7x-45x-stereo-binocular-microscope-with-14-pillar-stand.htmlThe main use will be for soldering and inspecting some 0.5mm pitch PLCCs etc. It has a working distance of 100mm, I'd like to increase this by adding a Barlow lens but have some questions on how all this Barlow lens business works.1) It seems the microscope has a 48mm lens thread so I'm guessing any 48mm Barlow will fit is this correct?2) Is there a difference in the width of view with different Barlow lenses?3) Do I need a 0.5X or a 0.7X Barlow (the scope is 7.5X - 45X Zoom). Is the following correct?0.5X will give 3.75X - 22.5X and a working distance of 1/0.5 x 100mm = ~200mm0.7X will give 5.25X - 31.5X and a working distance of 1/0.7 x 100mm = ~140mm4) Is fitting a UV filter in front of the Barlow lens a good idea for protecting the lens against flux and mechanical damage?5) Do the Barlow lenses usually have a 48 mm thread on the front that I can fit a UV filter to for protecting the lens?Cheers.

content: 100mm is already a lot of working distance. Wait until you have the microscope setup how on the bench you will be using it at, and access your comfortable working height before deciding to add a lens to increase working distance.You may find the microscope becomes uncomfortable to use if you increase the working distance which effects working height. Until you have the microscope you can't predict the comfortable working height and that will limit how much working distance you can make use of.As far as lens shields are concerned, I use a Leica 10446324 with one of mine, and the other I use a Hoya HMC UV(c) lens shield. Neither of them are particularly cheap but they do the job and don't noticeably effect the optics.

If you don't use the backlight (probably between 15 and 30mA), it should last one year if you use it an hour/day.If you don't use it that much, maybe check the current draw when the meter is off. Some Fluke 80 original series I have problems with too much current draw when it is off due to dirt/debris.PS. Dave did a video of the Fluke 87V current draw way back in episode 10.

content: The fake handles are about 36W instead of 50W. Gaps in iron to ceramic mean that temp has to run a lot higher for same tip temp. I've bought a couple replacement heads to refit dead irons for $3. Usable, but not the same as the real thing. I think for old electronics you would want as high a wattage as possible.

FWIW, Batterfly is located in Italy, but they're an authorized distributor just like Dancap.If you buy from Batterfly, don't forget you'll need an adapter for the EU plug (or wire in a UK plug).

content: First thing I've always done with a new soldering iron is to replace the flex with top quality silicone rubber flex. It makes handling *much* easier. The high flexibility means that it doesn't drag or fight back when you're moving the iron around. It doesn't tangle too and has a slight self straightening quality which means it doesn't remember the kinks from being folded away in the tool box or a drawer. It's highly heat resistant too - the best stuff won't melt if you leave your iron resting on it by accident but it's best not to push it too far deliberately. The best stuff I ever had was specifically rated for wiring fire alarms.

content: If his tips cost $60.00, I hope the iron has a good cord on it, lol.QuoteI use a 2 piece station + holder, and both pieces sit directly under my bench surface when not in use. Front right. I just let the cord dangle, but it's recessed a little from the front edge of my bench surface. When using the iron, I move the soldering iron stand to the top of the bench and then put it back when I'm done. The only thing the cord ever catches on is my right knee, occasionally, while soldering.The hot air station is the bigger bother. I have that set on my bench a little further to the right, with a slot cut into the bench where the hose dangles, so it is also recessed. And there's room to temporarily set/stack work in front of the station.This is all carefully arranged so that I can use these tools under the microscope. The soldering iron has a lot of reach, but the hot air station doesn't. If I can't bring the work to this exact spot, then I have to get creative.

It seems like I would usually take the time to use two irons when doing two parts of a batch process. And only using one at a time, with the other iron pushed off to the side.If just building a prototype, I would typically just choose the best tip that can do it all. Or stop and change tips... because really it's probably not that big a deal if prototyping.

Measuring in at 3.8 by 2.2 by 0.9 inches, the device contains a microprocessor - controlled video- switching system that can precisely sequence up to four color or black- and -white video cameras to a single video output. Small enough to easily hide or mount almost anywhere, it can be used for commercial, residential, and specialty security and monitoring purposes. Both the rate of sequencing (one to 225 seconds) and the number of video sources are switch selectable. CIRCLE 27 ON FREE INFORMATION CARD The V4x1 comes with a 110 -volt transformer, or can run on a 12 -volt DC power source, including batteries or solar cells. That allows it to be used where there are no standard electrical power sources, such as in motor homes and buses. The V4x1 has a suggested retail price of $199. NETMEDIA, INC.

If not just buy those ~$20 barebone PCB kit, search for esr meter. I am sure they are more or less the same as the MESR. MESR to me is overpriced with a fancy display.Just to raise your level of confidence in Deree, it is also rebranded and sold by IET labs.

However looking at the back of the power unit there seem to be two versions designated by a checkmark denoting which unit is supplied. Mine has CD-2SC checked. It was supplied with the T245 handpiece which would normally partner the CD-2BC, the CD-2CS would be paired with the T210 handpiece. Do they both use the same power unit with the tick box on the back denoting which handpiece has been supplied. I am just a bit concerned that the power unit may not have the correct output power for the T245.

content: Last year, I was in that situation. There did not seem to be a clear preference between people who had used both. Or rather, some people had preferences but they were split pretty evenly. I went with JBC because the temperature is adjustable. Metcal needs different tips for different temperatures.With your location, JBC is probably easily available, even used. While searching for mine, I asked one dealer if they had any refurb or used JBCs. They said "no, we never get them back!" The handpiece cables can wear out, and my first station had that problem. But even with a new handpiece, it cost much less than an equivalent Hakko, and far less than a new JBC. So look around. You might also find a used Metcal.

timestamp: April 11, 2016, 12:52:49 am
content: Just posting a new topic based off of my previous reply to a different topic.(newb-alert)My purchase order from 7 years ago says I have a Velleman (VTSS20U), while the manual says Duratool (ZD-929C).I have been informed that these are cheap clones of Solomon or Elenco. But if they look the same too, one surely is a knockoff of the other.Tips:There doesn't seem to be any standard for tips outside of the end of the tip itself.Some tips look hollow while others appear to have a solid core. From other threads, it looks to be true.I can see the value of both; Hollow will trap the heat inside (as opposed to the heating element being wrapped around the tip (external/hollow). On the other hand, solid tips are probably going to be able to have more of a stable temperature.Then you have varying lengths for the shaft of the tip. I'm going to guess that the inner/outer diameter is going to be different as well, but not sure if it based only on the heating element (40w iron vs 70w).And what is the shiny exterior vs the gritty/coarse (ceramic? galvanized?) coat?Compatible Replacements?:If I'm looking at buying tips from where I bought the station, I'm seeing a $15 shipping fee on a $2 tip.If I'm looking at Duratool, I'm seeing shipping overseas.If I'm looking at Velleman, they are telling me it is not one of their products.If I look at Solomon SL-30, they show tips below their station (821->827), but on the side link to tips from above which are 30T-??. (http://a1parts.com/solomon/index.html#SolderingTips for)If I look at Elenco SL-30A, they say their tips are NOT compatible with Solomon (http://www.elenco.com/product/productdetails/soldering=OTk=/solder_tip_for_sl10a--sl30a..1--8&quot;=MzA=). It does however say it's compatible with ZD931, but while that may be close to my (supposed) ZD939C, it doesn't explicitly say it's compatible.I'm just frozen in place not knowing where to move. My needs are NOT great. I may solder a few times a year, but it's likely to be even longer than that.My current need is trying to desolder a component from my induction cooktop, but the solder doesn't melt at all. I can roll my tip in a molten ball of solder, but the solder on the board doesn't do anything (almost like it's steel or something).
