content: As USB-C provides upto 20 V, I intend to purchase USB-C adapter 65W and use any available portable USB power supplies with adjustable CV and CC. I came across a pocket USB power supply fromlab401, but it can not be shipped to my country. I like the idea of getting clean voltage from the USB-C without the need to boost, but I'm also open to similar portable USB power supplies even with boosting functions or anything close to what uSupply does.

I recently bought 2 pliers from Knipex, the 08 21 185 and 08 22 185, but I am facing a problem with them, because they are very hard to open and close the jaws, most likely they are very tight, while my other pliers from Knipex are perfectly tight.Are you facing the same problem as mine ?

Touch screens don't work with me. In late May, I was checking in at the airport to go to a grandchild's graduation. My fingers didn't work. It was very early and a convenient guard kindly did it for me. Why doesn't the ADA apply to touch screens? Dry skin and big hands shouldn't be legitimate reasons to keep you from flying.

But now I have a screen which works enough to play around with and no idea what the connection is.The relevant connector is in the attached photo.

I found myself deliberately and consciously (as opposed to just not thinking about it) pressing the screen and making sure my hand didn't move laterally at the time. It occurred to me that this is how we have to use touch screens - deliberate and non-moving press, otherwise the thing thinks you're swiping and doesn't register. With real buttons it cares not so long as the thing clicks. Give a glancing blow with your elbow and it will work.But... it is just more natural to press the thing we're dealing with, so touch screens are nicer in that respect, just not so well implemented.

I had to buy a special adapter to program the 44 pin Intel chip. Make sure you buy the correct adapters (there are chips on the adapters and some of them have another connector for a cable which plugs into another slot on the programmer).

About A$100 for programmer + about 13 adapters from AE manufacturer store.Happy with mine but have only used it briefly for a few SOIC EEPROMs. The ZIF sockets are very handy saving soldering the device to a breakout board.T56 supports a few large memory devices like some eMMC I think but it's quite a bit more expensive.Software is basic but functional and has quite good diagrams showing pin conections.Pay attention to chip orientation. I find the ZIF latch somewhat backwards to what I'd expect i.e it's not near pin 1.XGECU not XGEKU so if the latter maybe not genuine? Or just typo?

content: I've been also contemplating building my own desolder station, and have investigated the JBC system.The DSV-DR, or"heating element" of the DR560, is basically a C245 tip in all but name. It can be physically plugged into a T245 handle and be driven by any station that accepts the T245.So yes, in answer to your question, a CD station can drive the heating side of the DR560. You will only need to replace/rewire the connector to make the station believe it is a T245 plugged in.You can then use it with the DSV-DR for desoldering or, in a pinch, with a real C245 tip for normal soldering.The vacuum side of things will still need to be taken care of separately.Hope this helps.Regards.

content: Many dehumidifiers today have a version with a pump. Turning on the pump is not an issue, as the bucket-full float easily can do that. Turning off is a different matter. Some versions use overheating of the submersible pump as he trigger. That approach did not appeal to me. The unit I got does not seem to work that way, but I dislike paying $50 to $80 more for an aquarium pump.Anyone here do a tear down? Why not simply use a timer?I want one for my shop in the barn, and cosmetics are not an issue, but raising the dehumidifier above the drain is.John

You need equipment if you are doing this because it comes off like being a total shill.They would be interested because1) could be counterfeit part that got into their line2) could be assembly line issues with thermal stuff, soldering stuff, chip handling stuff3) their vendors could be storing them poorly, mishandling them, etc.

I'm from Boost (boostbike.uk); we engineer all our own motor drive systems and are designing replacement VanMoof circuit boards to prolong the life of the bikes in the market, whatever happens to the VanMoof system. VanMoof uses an STM32, our system used Nordic bluetooth chips with super low resistance automotive MOSFETs.If anyone has any old or broken VanMoof main circuit boards that would be useful, so we can use the physical profile for ours for various VanMoof versions. We're also up for buying end-of-life VanMoof bikes for testing purposes.

content: Please read the threads we have here by searching.https://www.eevblog.com/forum/reviews/budget-soldering-station-with-hot-tweezers/FX1003 is decent for small size SMDs 0402, 0603, etc. It is the cheapest high quality tweezer you'll find. You can combine it with an older Metcal station for ~$100, so $250 total for everything. But they are probably hard to find in Croatia, might be more expensive.Atten looks OK, its only slightly cheaper at $210 for the station with the tweezers, may not be as good for very small passives (0402). But depends on what you intend on using it for, larger parts it might be better.

Pace WJS100 Soldering Station; Tips? - Page 1

content: I have a Pace WJS100 High Power soldering station. I am extremely impressed with it, and the performance is exceptional.It uses the older TD100 (plastic) handpiece, and is specified for use with the Pace 1128-series (gold end) High-Power Tips.I was recently gifted a large batch of brand new 1124-series tips (black end), which are also used with the TD100 handpiece, but are rated as the TD100 Standard Soldering Tips. These tips are used with the non-high-power soldering stations.Both tip types are in the IntelliHeat category.My questions are:Does anybody know what the electrical differences are between the two types?Are these regular tips usable with the high-powered base station?

timestamp: July 03, 2023, 01:17:30 am
content: As far as I'm aware The WJS100 uses unique tips for higher power (yellow "gold" ended). The black ones should work in that TD100 handpiece but just are not intended for that station, you will probably kill them if you try (or worse).Intelliheat MBT or ST stations will run those black ended tips, I've the MBT350 and TD100A which is the updated aluminum handpiece version (with newer stand) of the same handpiece you have. The Pace ADS200 basically combines the function of the black and gold tips into the one high power station.If you have a bunch of them and or dupes send me a message with what you have I might be interested in doing a swap or buy some so you can get a few extra golds. An alternative would be to pick up a secondhand Intelliheat ST station.

The device works great and can be controlled manually using the front panel, but we have no idea how to control it over the RS232 interface. Amonics has been no help as this device is 15 years old and they say they don't have any old documentation or software from that far back. I've been able to get documentation on their new (read post-2011) EDFAs, but the new commands don't work on the old device.Digging around on google hasn't turned up much beyond an old manual that says there was at some point a LabView interface that could talk to the device over RS232, but nothing beyond that.

I tend to use leaded solder due to the age of the items (end of 70's / early 80's).Which tips would you recommend?

author_rank: Super Contributor
timestamp: June 13, 2023, 03:38:22 pm
content: For thru-hole, mostly chisel tips but an extended conical can be useful for special situations.For SMD I prefer bent conical and hoof tips. Sometimes you want to heat both ends of SMD passives and push them off the pads: quite large chisel tips can be abused to do this if there is no soldering tweezer available, or you could use a knife tip as they are wide enough.For desoldering, something like DFP-CN4 and DFP-CN6 would do most pins if you don't want to buy the whole range of sizes. Just make sure that the annulus of the tip is making contact with the pad ring (and don't press down!)For thru-hole, SFP-CH20 for small pins and SFP-CH50 for large lugs would be good.For SMD there's the always handy knife, SFP-DRK50, and the hoofs SFP-DRH35. Bent conical is SFP-CNB04 and extended conical is SFP-CNL04.The 'F' temperature range is around 750° F and is widely useful. You could also use the 'T' series (650° F) for most things that don't have difficult ground plane connections. It lets you work slower without cooking the laminate if you are not very dextrous.

I am pretty use it's Windows 10 22H2. I have not tried it on it yet. It is too convenient to have the VXI-USB working on this one. So if it works, the transducer test has to be moved to that Windows 10 machine which is scheduled to loose support in 2025. It shares the network drive and printers, so it isn't that bad.22H2 on Window 11 just has me pissed off a bit at Microsoft. I guess there is no way to let them know they broke something?; not that they would care.For right now, I turned Windows 11 updates off.

At that point it's up to manufacturers to maintain and adapt their own drivers and software to newer standards. It may or may not be what happened with 22H2.
