content: I plan to purchase JBC’sCompact Station for General Soldering (CD-1BQF)to make cables for use with a cinema camera, audio recording gear and lights.*I’ll mostly, but not exclusively, solder cable to connectors that have cup terminals (e.g. XLRs). Before I order, I’d love to get views on what T245 tip cartridges would be useful for the kind of soldering that I’m talking about.**As I write this, I’m looking at the terminals on a Neutrik 3-pin XLR. A chisel tip would seem to be the obvious choice. Among those, I’m intrigued by the bent chisel tips in the first photo below. They should provide flexibility in placement of the T245 handle, and the first in the photo (C245-732) appears to offer a good deal of thermal mass. Thumbs up? Down?Should I be considering the rounded barrel/pin/connector tips shown in the second photo, or are these useful only if a tip closely matches the curve of a connector’s cup?I’m also interested in the T245 solder pot cartridge (C245-SP01) in the third photo. JBC has told me via e-mail that it’s made of titanium. I’d use it to tin stranded wire. I like the dimensions (15mm x 18mm x 10mm deep), and the ease of keeping it at a constant temperature. I'm quite content to take a break, after tinning, while the pot cools down. At US$100, I'm OK with the price. Does anyone have any experience with it? Views?If I purchase the solder pot cartridge, I don’t intend to purchase the stand for it (fourth photo). At US$234, it costs more than I’m prepared to pay. Does anyone have thoughts on a simple alternative, whether off-the-shelf or do-it-yourself? This two minute JBC video shows how the stand works, which I think is clever, but overkill for my needs:JBC Solder Pot Cartridge Stand* I realise that some people may think that I should purchase a different soldering station. I chose the JBC after carefully considering Miniware’s TS100/TS80P, Hakko’s FX-888D and Pace’s ADS200. I also looked at Metcal, Thermaltronics and Weller. I've spent enough time looking at options, and just want to get on with my decision :)** If anyone is interested, here isJBC's Cartridge Guide. T245 cartridges, of which there are about 140, start on page 22.

content: I'm no longer looking for input, having made decisions on the questions above.Ihavelearned something new about JBC's CD-B (aka CD-1BQF) soldering station. I thought that the warranty is two years. While reading the user manual yesterday, I learned that it's actually three years. That's three times as long as the Hakko FX888D and Pace ADS200 stations that I was considering.

Correct tip for Weller W61 (Magnastat) - Page 1

content: Hi,I'm thinking of buying a Weller W61 soldering iron - it's one of those where you change the temperature by changing the tip. It comes with a 370C (700F) 2.4mm chisel tip. 370C is the same as the old Magnastat number 7 tip I believe. I would be using the iron for repairing old through-hole stuff with leaded solder (60's-70's electronic organs, 70's-80's analog synths, old pinball machines etc.) and building new through-hole stuff mainly with leaded solder (will get into SMD later and perhaps into lead-free, too, but I'll get another tool for that stuff).Now my question is: is that tip the correct for my planned work? Or should I buy a tip with a lower temperature? What type of a tip people used with their old Magnastat Weller's for leaded through-hole stuff, tip number 6 or 7?Thanks in advance for any insight into this!

content: For production and general purpose use, the 700F tips are the ones to use. The 600F tips are only suitable for very new parts and boards which have no tarnishing, and rework where you want to minimize the damage to a printed circuit board.I like the shorter and fatter tips because they have a greater thermal capacity making soldering faster.

content: I have a W60P3 and always used 700°F (370°C) tips with PbSn solder. I tried an 800°F (425°C) tip and thought it was too hot, tip got black fast and tended to cook whatever I was soldering. Smallest CT5A tip I used for years for PCB work but it is a large iron overall. I would get bigger tip e.g. CT5B or CT5C for larger through-hole or point-point work. Either way it has lots of heat.

content: I have the 602D+... solder iron 388c to 412c temp changes and than symmetric (230V & 30mA) switch off, as on different differential brands.With warranty, the fixed the temperature jumps....But if I changed the EU connector in reversed manner, same differential issue. As changing temp from 380c to 410c.We exchanged the the solder iron, no change...So opened and studied the hole things and started to revamp:. transformer 180° turned so input is on the back, and put on a rubber for less noisy. removed the USB power, while never used. added on the back a on/off switch so stuff get quiet if not used. ALL solder points are as cement solderedand that from a solder iron company. OK, chica do not understand with soldering to made contacts and not as fixing... after re soldering as it should look brilliant / shining ... after switch on temp now increases more slowly. while phase or null of 230V will go directly to the right heater front connector dependent of the symmetric 230 EU connector. added a filter for the transformer & connected directly to my new power switch (cable to the board off), while this may brings bursts to the power, who knows. twisted all internal cables 230V and all of the transformer and all 230V in addition isolatedll just asengineering and be warned of the 230V phase to the front ... now no more 30mA symmetric power switches off... so farJust for short & using SMD soldering good enough

content: Does anyone have experience with the SP-50 solder paste from Relife/Sunshine? Or the newer SP-X which appares to be the same product(?)Why do I care? Because it's much nicer running the reflow oven 70 degreees colder than I need for SAC305. Less smelly, shorter cycle time, less chance of damaging connectors etc. On the other hand the melting point is not low enough to be a problem in most cases.I have tried SP-50 and has a few observations:-The melting point of 158C appares to be correct.-It produces nice shiny joints when used with ENIG, similar to 63/37.-Uneven joints when used with leaded HASL.-It's strong, in my test the copper came of the board before the solder failed. Also not brittle.-The shelf life appares to be short. Old paste becomes dry. If I mix with extra flux leaves unmelted solder balls around the joints.And a few questions:-Does anyone know what's in this paste?-Does anyone know if it's really ROHS compliant and not some mix of lead or something even worse.-Anyone got good results with this paste when it's more than a few months old? If so, how?

content: I'm trying to find an ext antenna adapter for an old portable CRT tv input, but I don't know the correct name to find one. In a nutshell, I need to get analog a/v output from my D/A converter(s) and VCR into this little portable tv.The input looks kinda like a 3.5mm headphone jack and seems to use a tip sleeve plug—I'm assuming one is for video and the other is mono audio? I saw one in a video that had the 2 vhf screws -> 75 ohm plug (but they didn't say what adapter it was), but shortest way would be BNC or Coax -> 75 ohm plug. In the future I may need to go composite RCA video and mono audio to the plug as well, but that's an afterthought.If I use two adapters: they make 300 ohm to 75 ohm transformers (coax to 2 prongs like the vhf input on old tvs) and they are readily available on ebay and amazon. Then I would attach that to the adapter that has the 2 screws and that 75 ohm plug.I'm not opposed to making something custom. I'm just not sure what type of male plug is needed etc. and a pre-made adapter would be fast and easy.Any advice is welcome. All the adapters I'm finding have a coax connector instead of that plug.Thanks!

Using a cutter to remove the insulation would cause it to unravel several centimeters. This was really the only way to get a decent result. However, using it would cause you to be thrown at with sharp objects. The smell was terrible.

content: CHDK is indeed a great way to make your Canon Powershot point-and-shoot intelligent. Back before drones, I used it to do timelapse videos and kite aerial photography with my A590. It loads in your Lua script from the SD card on boot, and doesn't make any permanent changes to the camera. So it's basically like loading in an app to supplement the operating system. And it will react very quickly to any change in the scene - great for fireworks, lightning strikes, birds about to land, etc.

content: I'm looking at these too, are they any good ? I am always nervous about what they mean by "effective soldering area" is it simply the drawer size of the actual area that will be properly heated for soldering. I have one of the small units that came out a few years ago that is 800W and it has two bulbs if you don't put the boards between them it does not work so only 30% of the draw area is actually useable.

content: I've had my CHM/BRTRO 420 for 2+ years now, and was planning on upgrading it with Blair's Blazing BRTRO board (https://github.com/bleckers/brtro-420-better-blazin/wiki), when the main controller died. The symptom was that, after heating, one of the elements would no longer turn off - which made for a batch of broiled boards before I detected the problemI took the system apart, and found a toasted driver mosfet with burnt traces - a sketchy board design at the least. From Blair's blog on HAD, the controller uses an obsolete MCU, which reinforces the low cost driven nature of the machine.In these two years, I've processed thousands of boards, and found a couple of issues/constraints:The edges of the tray are IR shadowed, and don't reflow well. While I can fit a 3x3 array of 10cm panels onto the tray, I got many failed reflows on the outer perimeter - so I now only do a 2x2 array in the middle of the tray.I switched to GC-10 leadfree paste - and getting the oven dialed in to handle it was a pain - the UI for setting curve temps and times is a disaster, especially coupled with the poor thermocouple placement and accuracy.Now that it died, I'm going to replace it with a T937M - the larger tray should let me go back to a 3x3 panel array AND leave enough slop around the edges to avoid the cool areas.-John

The idea is to clean up the leads so they stick well with solder.I thought either that, or using steel wool.. which seems safe so long you have a wrist strap on. But it does not come on a nice pen.How about fine sand paper or scotch brite pad for that regard? Sanding sponge? sand paper glued to a stick? cotton buds?

content: Hi all.I have a basic but good quality analogue temperature-controlled solder station. It is the British brand Antex. I wanted to try a Hako style iron on it, so I bought a couple of clone irons and replaced their connectors to work with my solder station. It worked like a charm. However, the thermocouple/sensors in the Hako-style irons are clearly in a totally different range to the stock iron, such that I can only use the very start of the temperature control or the heating circuit remains permanently on.I can get a good working temperature with it turned down to just above the lowest setting but obviously I have no range of temperature control at all. Is there a simple modification I could make to the base unit or the iron itself to shift its temperature sensing range? The base unit does have a calibration trimmer, which Ive turned down fully, but it doesn't have enough range to fix the issue.Thanks.

T12? 936?T12 have thermocouple, which means they work outputing voltage.936 are PTC based, soy they are just variable resistors.You will need some reverse engineering there. Is the original heater already damaged?You need to know what is the measuring circuit expecting from the sensor.Maybe then you could build some kind of translator, or modify the amplifier input.

Also look at the wattage of your station and search on aliexpress.com and dhgate.com etc (chinese websites) for "48w soldering station" etc, you might find it under other brand names. You can also try looking under google images as well when you get it a hit, sometimes it yields good links to sellers.To thank posts, there is a little thumb button "say thanks".

content: The models of interest are the Quick 861DW, Atten ST-862D, Quick 957DW+, and Quick 857DW+.Setting aside the 861DW and 862D higher end models I'm thinking that for the limited amount of hot air work I do the two lower Quick models can probably suffice (but I'm willing to be talked out of this).What I can't find is something that explains if the 957DW+ is newer (or older) than the 857DW+. The 857DW+ seems to be difficult to find in the U.S. As best I can tell the 857DW+ is a 580W unit but it is not listed on the Quick web site - so maybe it's been discontinued?At tequipment.net the specs say the 957DW+ is also 580W and with an air spec of 50L/min:https://www.tequipment.net/Quick/957DW+/Desoldering-Equipment/Rework-Stations/?v=0(the site says it's a 957DW+ but the product photo says 957DW without the plus)Anyone know what the difference is between plus and no plus?Adafruit also says the 957DW+ is 580W but they show the air spec at 100L/min:https://www.adafruit.com/product/1869(the Adafruit product photo shows the plus)The Quick site says the 957DW+ is 400W and 50L/min:https://en.quick-global.com/Product/QUICK-957DW+-Hot-Air-Rework-Station.htmlI'm guessing Quick's specs are the correct specs....?So, between the 857DW+ and the 957DW+ is the 857DW+ the preferred model (due to 180 more Watts and double the L/min)?And if the 857DW+ is only available with a bunch of shipping cost from Asia, then does it make sense to live with the 957DW+ for around $100? Or is it "necessary" (TEA) to go for the Quick 861DW or Atten ST-862D?Thx

While testing the unit under load in constant current, i found out some strange behaviour and couldn't find any thread that described this issue so i'm starting this one.What I did: I loaded up the powersupply with some 8ohm 100W resitors and applied a constant current. After a while the fan kicks in to cool the swithing mosfets and I notice a current drop of around 160mA on the output of the supply.What use is a constant current mode if the power is measured before the output and takes into account internal components?Is anyone else seeing this behavior?I thougth it might have something to do with the modification (placing an RC filter on the gates of the swithcing mosfets) but I undid the mod and the behaviour was the same.I found the schematic of the board LW-K3005D-1 but as I'm not an EE, im turning to you guys.Would there be a possible mod to remove the current of the fan from the CC measuring circuit?Greets
Do cellphones with highspeed video recording just fake it? - Page 1

content: I've heard some cellphones that claim 240fps, 480fps, or 960fps video recording don't actually record at that rate. They record at 30fps, 60fps, or (if you are lucky) at 120fps. They then do temporal interpolation to generate frames between the recorded frames, to SIMULATE high speed video recording. Some simply duplicate frames, while others use the much better motion vector interpolation technique. However, I have never heard of any cellphone that ACTUALLY records at any speed over 120fps without interpolation. So I'm not sure if all cellphones that claim high speed recording capabilities fake it, or only some of them fake it (while others truly have this high speed capability)If there are any cellphones that can truly record at frame rates of 240fps or faster, please let me know.

The 960fps are 240fps interpolated.I know the 120 and 240fps are true because I tried setting the oscilloscope at 5ms/dic.A frame at 240fps is 4.1mS, it should show the trace being drawn close 1division (a little more due the persistence).And at 120fps it's 8.3mS so it should be close to 2div.And it did exactly that:720p 240fps:1080p 120fps:However at 720p 960fps it's very different, a blurry blob moving around:

content: Originally a kickstarter called FPS1000, this camera (most recently called FPS4000, and supporting even more frame rates than the original design) was basically a "low budget" (well relatively low budget, as it cost like $2000 instead of $50000) was being sold on a website called Slow Motion Camera Company, who's homepage was at slomocamco.com. However, that website seems to have disappeared (slomocamco.com is now just a dead link), and there is no mention of it disappearing on other websites. Even digital camera forums don't mention its disappearance, or any possible new link (if the guy just moved servers). All references to the guy are on tech blogs referencing his kickstarter, and such blog entries seem to be from around 2014 (though I know that slomocamco.com was a working URL even as recently as last year). He seems to have just disappeared without a trace, and without anybody else on the entire internet even mentioning his disappearance (and thus the disappearance of what was probably the lowest priced high-speed video camera ever).Does anybody here on EEVBlog Forums know what happened to this guy and the high speed cameras (FPS4000 units) that he was selling?
