content: I need help sourcing this part where the barlow lens screws on to. I purchased this used AmScope sm trinocular microscope but somehow this barlow mount doesn't have any threads where the barlow lens can screw on to. I tried searching online for this parts with no luck. Any help of sourcing this part?

content: Generally, auxiliary objectives (barlow lenses) mount pretty close to the lens they are extending. What is the thread on the exposed end of the microscope? Having you tried screwing on an (0.5X?) lens, there, and leaving off the flared, thread-less part?Have you talked to Amscope? They should have someone there to support their products.

It's a real basic iron, the base unit consists of a transformer, a power switch, a fuse and a resistor. It just puts out 24 volts AC to the iron with a 1K resistor connected across the outputs.

Has anyone ever used one of these and are they useful for anything or is just a child's toy that's made to look like a soldering iron? The box says that it runs off of 6 volts but it doesn't say how much power it draws but the wires on it look like maybe 22 gauge so it can't be much. I don't know how old it is but the rubber bands that were used to hold the wires in a bundle have long ago melted into blobs. Does anyone know when this was made?

Uyue 946c temperature calibration - Page 1

content: Anybody figured out how to get into the temperature calibration mode of the newer style (white and teal colour scheme) Uyue 946c hot plates? The way the controls work don't seem to match the provided instructions.The instructions say you press SET, the display will show "00" (or whatever the currently configured offset is) and you use up/down to adjust positive or negative offset. Then press SET again to save.But that's not correct, because what that describes is just the regular temperature adjustment.I'm not sure the provided instructions I got are even for this model, as they mention a "vacuum pump" in several places.Here's what I have figured out so far about how itactuallyworks:- To set temperature, press SET. Display will flash set point value; use up/down to adjust temperature; hold arrow key to fast increment/decrement. Press SET again to confirm, or wait for it to timeout.- To turn off without using rear power switch (i.e. go to standby), long press SET for approx. 5 secs. Same again to turn back on.I couldn't find any other modes or functions with other button press combinations.

Then a 30 to 50ft hose that will go to a 3 way manifold connecting to 1 branch of the two way manifold. from the 3 way manifold it will branch to 3 regulators with filters. there will be shut offs before each regulator. from the regulators the 3 lines will go to a metcal mx-ds1 desoldering tool, a metcal dx-250 fluid dispenser, and just a handle with a trigger to use to spray compressed air.Looks like I should use 200psi hoses. I was thinking sticking with 1/4npt for everything except for the hoses to the actual tools which are already provided esd safe lines.Quick connect 1/4 npt fittings for everythingIs there anything I need to take into account or changes I should make.

content: I piped my shop air around my basement and into the garage using 1/2 PEX water pipe. The compressor is in the basement. System pressure is maximum 120 PSI. Unlike PVC which can explode in a shower of fragments, PEX fails by splitting open lengthwise and doesn't fragment. I am personally satisfied that PEX is safe to use in this way but you should do your own research if considering it. At terminations I use a PEX to FPT (female pipe thread) fitting called a "drop ear", which can be mounted to the wall. Each termination has a ball valve followed by a regulator/filter and a quick disconnect fitting. I have two drops in the basement and one in the garage. I was meticulous in installing the system to ensure no leaks. I keep the compressor connected and powered at all times. As long as I remember to close the ball valves when I'm finished working, the system losses air only very very slowly. The compressor kicks in approximately once per week to top up the pressure. Even a tiny imperceptible leak can increase that to once per hour or more frequently, so if you want the convenience of an always ready system, you need to make it leak free.At the workbench, one use for the shop air is for my Metcal desoldering iron, which uses a venturi to create the necessary vacuum from compressed air, instead of using a pump.

What Quicko T12-942 MCU is this? - Page 1

content: Hello All,Having purchased a Quicko T12-942 soldering station, I was dismayed by the illegible dark display screen, so successfully replaced the OLED SSD1306 display module with a new one, however, in the process something went wrong, and the whole board went dead. After much consultation with my ever eager faithful ChatGPT assistant, we narrowed the problem down to a failed microcontroller. However, the SOP20 MCU on the control board does not have any identification on it! I assumed it was an STC15W408AS, however the pinout does not match. The STC15W408AS has the GND at pin 9, and the VCC at pin 10, with a Cap between them. On this board, however, pin 9 is the VCC and pin 7 is the GND, with Cap between. Any idea of the ID? The PCB has no ID other than "16-24V3A DC" printed at the top right.Yes, I realise that even if could find a replacement I would have no program to load into it. But, maybe it is possible that the PCB could be modified to take a STM32 or a STC15W408AS? Assuming that the VCC and GND can be easily re-routed.

content: "Out of the box", the display was always dark, though the iron would heat up. I don't think that this Quicko T12-942 had a brightness setting in its FW, anyway I found it too much of a struggle to navigate through the menu, because there seemed to be no light whatsoever. I could make out that the menu on the display was responding to the rotary encoder, but that was it. I learned from online forums that mine was not an isolated case, and that the remedy was to simply replace the display. But, rather than soldering the 30-contact connector flat cable to the control board, the advice was to connect only the 4 I2C pins on the display module to their counterpoints on the control board pads. And yes, I did remove the protective film.

The downside with them is that the documentation isn't very good, and in particular the modbus register info is often incomplete or has a number of errors. To help out people working with them, and to make it visible to search engines for people looking for accurate info, I've put up apage containing the hopefully-correct register values and descriptions. Corrections and updates welcome.

content: Were you ever able to figure this out? I have a second hand MX-5200. A couple of cartridges throw this error after ramping too much power. One is a Metcal tweezer cartridge (its sibling is fine) which I've used for maybe 20 active hours since new. The other is a new Thermaltronics cartridge. I've tried a different hand piece and get the same result. If it were just the one tweezer cart I'd assume that just went bad somehow, but I'm suspicious that the new Thermaltronics cart is also bad.My MX-5200 likely had a hard life. I had to replace a broken power switch and unstick a relay to get it working. So maybe there's some other marginal component on it. But all of my other cartridges work fine. ¯\(ツ)/¯

content: Hi all, I’m planning to buy two microscopes for my lab: one for IC decapping and die-level reverse engineering (AmScope ME300 metallurgical microscope with 20MP USB 3.0 camera), and one for PCB work like soldering and inspection (AmScope ZM-4T stereo zoom microscope with 18MP camera on boom stand). I want to take accurate measurements on captured images and also record videos easily. I’m considering EAKINS IMX226-style HDMI/USB cameras — are these good for clear image capture and reliable measurement? I’d also appreciate suggestions for a solid XY mechanical stage for positioning decapped chips. Any feedback or recommendations would be great. Thanks!

content: "Correctly" supposes a measuring procedure that fulfills your requirements. I will leave it to you to decide if a potential 5–6° parallax error and reduced, usable field of view are going to trouble your measurements. I know a couple groups who said it would have troubled theirs, while inspecting fiber optic and chip on board assemblies, and chose more optically complex stereo microscopes. (I bought the microscopes when they retired them.)

PACE ST125 pump operation question - Page 1

content: I have a quick question regarding the operation of the PACE ST125 de-soldering station. Does the pump run only as long as the button on the hand piece is depressed, or will it run for a few seconds automatically. I know the PACE stations from 25+ years ago ran for a preset amount. I am thinking of purchasing one for students to use at the university where I work, and don't want to deal with constant clogging.Thanks in advance.

content: I presume it has a minimum run time like other Pace desoldering stations, but the real key for non-clogging is to get the later SX90/SX100 handpieces. The tips on those are extended and resist clogging and if something terrible is sucked up and they do clog you only need to replace the tip itself--there's no possibility of clogging the heater tube.

But I have issue with its T210 handle I really was hoping for T245 one as it's cartridges can make full use of the power the station can provide.OSS Teams one is an option because it is cheap and if I have to deal with safety issue, it might as well be cheap.I have other options available; here are the two websites from where I can order from<https://babaocamachine.com/repairing-tools/soldering-station-iron/><https://robu.in/product-category/mechanical-parts-and-tools/soldering-tools/soldering-stations/>Because of our relationship with China very few Chinese clones come to India.I just want a decently safe and durable soldering station; I have option to get original JBC tips hence looking for JBC clones.

content: It appears Weller no longer sells spare parts for this oldie.I wonder whether the cartridges of the DXV80 would be compatible (T0058741815N). Being made of cardboard they have limited reusability, but you get 5 in a pack.Perhaps you can buy a sheet of the material the filters are made of and cut your own, but I do not know the material. It's nothing magical, but obviously it should be heat-resistant and allow enough airflow to get good suction but at the same time filter enough to protect the pump and prevent the vacuum line from gumming up. There was a topic about it recently (link), but no conclusion on what material it actually is.

I guess if there is something that utilizes an off the shelf board that is reliable I can flash it up.Even a 4G auto phone home dialler type device would work, will be self monitored so needs nothing more than caller id to alert. Don't need tracking or gps it will be fixed within reception range.Even if it is low power I guess I can always quickly cobble together a decent battery for it with charging but I don't want something that requires constant mains power or even constant battery depleting power draw if possible.Quick hacks are fine. Uptime of several months would be great but as I said I can extend battery sources.

I really don't want to install the app. The name of the app is FanLamp Pro by XuRenNan on the Google Play Store.I would venture to guess that the fan will be controlled via WiFi or Bluetooth. I did not teardown the fan yet.From what I can see on the remote control casing it seems to be 2.4ghz frequency. I for sure though the remote was going to use an ESP8266 or ESP32 utilizing the espnow protocol.If anyone can help it would be awesome. Thank you.
