content: I've got some rubber ESD mats for my workbench, of course, but I need to do something about my PC desk. Ever since I got new carpet and it got colder I keep giving huge zaps to my keyboard or mouse, which often causes the keyboard to reboot and sometimes one of my monitors. It's probably caused some of the PC gremlins I've been seeing recently.All the ESD mats I can find are either silicone or hard rubber, which aren't great mousing surfaces. I'd like something softer and more fabric-like. The only product I know of that has a nice surface and is actually tested for ESD is the Gamers Nexus Modmat (https://store.gamersnexus.net/products/modmat-volt-large) but ideally I'd find something smaller and less gamer-y.Or is there some other solution I should try? Connect a grounding strap to the metal frame of my keyboard?

content: Yeah you can try a ground wire from the keyboard frame to earth, at least for a quick test, then if it works add a resistor. Is your mouse made of metal as well?Another option is a humidifier if the humidity of the room is incredibly low.

content: I’d put a large, grounded ESD mat on your desk and then put your mousepad of choice on top of that. Consider an ESD floor mat. You can also get ESD sprays for surfaces and fabrics.If you’re the arts and crafts type, you can buy woven nickel fabric (normally used for RFI shielding) and make your own mousepad, perhaps. I’ve used woven nickel adhesive tape to turn ordinary footwear into ESD footwear (which passed ESD testing).

content: I did find a bunch on AliExpress by searching "anti-static esd mouse pad". Including one by, appropriately, EARTHING which promises to improve your health:QuoteThe claims go on. None of them look like great mouse pads, no stitching around the edges to be seen. And the ESD claims are somewhat dubious. But beggars can't be choosers I suppose.

content: hi all i have the 853D 3-1 soldering sation which i love, Sadly i have a problem where the Voltage regulation is not working, i am getting a voltage output of 35V and also 35V is displayed on the volt meter and i have also confirmed it with multimeter.i have tested the potentiometer and that is working all OK, so what could be the problem? Why is it outputting 35V ( i am unable to control the voltage using the voltage potentiometer ) when it should only be 15V max?

I had told them i just need to know what needs replacing i will repair the device myself.Did you have any luck in finding the faulty component? Is there anyone else out there that can give some advice on what may be the issue.MANY THANKSZZ

content: Had a Zeny(Yihua/WEP?) 853d ,0-15v ,1A/2A(marked on front analog meter, but no clue where that supposed 2A capacity comes from---meter only goes to 1A),stuck at 30 volts,after >1A load exceeded supply. First thing was to get rid of mis wired,factory AC cord--hot and neutral switched--dangerous. Main board #youde853mdV6/control board #yd853sdV4---transformer date of 11/25/2018(so a 2019 model). Contacting Zeny for a schematic went nowhere. R33 was obviously burnt--should be 150 ohm,3W. TIP3055 on heat sink--shorted out. Original specs on it--15A/60V/90W. Replaced it with a 2N6487,heat sink grease(none before),because it was on hand,and spec'd close--15A/70V/75W. Wasnt too worried since its only a 15V/1A supply. Replaced burnt resistor,and stood it slightly above circuit board for better cooling. Plug into 100w series light bulb,AC fuse saver cord---no smoke and proper power supply adjustment now possible. Thanks to this forum,i was able to read thru other clues,to keep this out of the landfill. Hope it helps someone else.

Even though this is against the forum's statutes and usually, I'm not the "faint of heart" at all regarding tearing down my stuff, I'll leave my RadiaCode 101 in one piece...

No such luck. Its made in a certain country that is impossible to get in touch with right now that rhymes with "Mussia", so I now have a $400 paperweight.Anyway, here are some pics of the inside. These are really close up since everything on the board is crazy small. I didn't take the board out, so its only one side. Im hoping to find the files to re-program it through the 5 pin interface, but so far, no luck.
ZD-915 Desoldering Station Replacement Tips - Page 1

content: Hey all,I recently bought a ZD-915 desoldering station and wanted to grab a handful of extra tips (and other parts like the filters and a spare tube). However, I have not been able to find any info on what tips actually fit the dang thing or where to source them. I have seen N5-X series tips (N5-1, N5-2, etc.) from Aven Tools that look quite similar, as well as the Hakko A100X series tips that also look similar. I don't know for sure if either will actually work with the ZD-915, nor have I been able to find the filters and glass tube except from Rhino Electronics, which is out of country and also appear to technically be for a cloned/rebranded ZD-985 as opposed to the 915.Does anyone have experience getting replacement tips (and other consumables) for the 915, or know which parts are correct and a good place to source them either in the US or China?

They have the tips, filters, replacement glass tubes etc. and they look similarly cheap.https://www.newark.com/w/c/tools-production-supplies/soldering-stations-accessories/desoldering/prl/results?st=proskitHope this helps.P.S. The tips come dip tinned so the ends look solid domed. The hole doesn't appear until you heat them up and press the trigger.P.P.S.

How are people's experiences with them?And secondly, are there similar accessories you can use with the Quick 861DW station? Or would the JBC ones work well here?Thanks,Victor

Why do short wavelength LEDs also have a weak broad spectrum emission? - Page 1

timestamp: October 28, 2022, 01:08:50 am
content: While the peak wavelength of a blue, violet, or UV LED is at the intended wavelength, these short wavelength LEDs also have a weak broad emission at longer wavelengths (all the way up to red). While not noticeable under normal conditions due to the very high intensity of the the emission at the desired wavelength, when viewed through a spectroscope, this broad spectrum emission becomes quite obvious. Why does it exist for these short wavelength LEDs, but longer wavelength LEDs like green, yellow, orange, or red, don't have similar weak broad spectrum extra emissions?

content: Please note that the "glass kit" also comes with a - IMHO - slightly different front seal (compared to the cardboard containers).The inner dimensions of the tube need to be pretty close to OEM, otherwise the aforementioned seal is not airtight. While the cardboard container is pressed against the seal, the glass seal plugs into the tube.Of course the tube need to be pretty close to the outer diameter as well, otherwise it won't fit to the holder.For DIY, I'd say this is regular borosilicate glass. So a chemical lab supplier might be a good place to check.The spring could be made of some random piece of metal, I guess.

The front edge of the tube presses against the seal. The narrower part of the front seal presses into the plastic housing to retain it in place.As far as the metal baffle: just use a tiny wad of brass wool stolen from your soldering iron.

But for a hobbyist, this can be a cheaper way to have a dual iron station.Relevant characteristic of the Aixun T3B is the fact that the back stand socket uses pin 4 as the sleep stand signal. Therefore if other stands are to be used they as well must have the same pin 4 connected to the stand iron metal resting holder (this can be verified with a multimeter in continuity mode).Enjoy" alt="" class="bbc_img" />

content: Good evening! I have old Pace PPS-200C that is having motor/pump problems. I noticed it started leaking oil out of the one of the air inlets and bogging down and decided to check the filters and and vanes of the pump. The felt filters had decent amount of oil in soaked them, but the vanes looked pretty clean. The problem now is I can't seem to find any replacement filters or carbon wear plates. I was wondering if there is any place I could find these? I should note my air filters look a little different than the ones shown in the manual for the unit. I'll include pictures of both. If replacement parts aren't available does anybody know of a possible retrofit for the pump and/or motor? Or is the station a lost cause? I should mention I bought the unit used a while back and this is my first non-work experience with a Pace unit, so I'm still new to a lot of things related to the brand. In retrospect I should have probably looked more into replacement parts when I bought it.(side note this is my first post, so I hope I posted this in the right place)

You just need to apply +5VDC to the fan.Usually in modern computers, the usb port is protected from short circuits and overloads.I believe that noctuca fans are quite good quality and you shouldn't have any issues connecting them to the USB. all you're asking is a way to complicate what is simple.

content: I accidentally plugged in my Hakko FR-301 Desoldering Tool, rated 120V, into a 220V outlet.I turned it on and I heard a "click", then I immediately turned it off. I then plugged it in to a 120V transformer to test it, and at least the pump is working fine. It started heating up for a bit, but then it stopped heating altogether.I opened it up for a visual inspection and there is no visible damage on the PCB or anywhere.According tothis post, all I would need is aheating element.I'm looking for opinions and thoughts regarding this being the part needed, and help understanding what exactly fails in this heating element, can the part itself be repaired?Thank you.

content: It makes sens that the heating element would fail. It's a resistance powered by mains voltage and most likely controlled by a triac. Basically it overheated and the resistive wire inside melted (think of it like how an old incandescent light bulb dies). You'd need some way to mend the wire that can also withstand the heat. Maybe it's doable with specialized tools but IMO you're better off replacing the part. It's a consumable after all.

Annoying but its there. Is it the sensor problem ?#4 It seems like the camera has to be twisted way out of parallel in order to produce parallel image.

It still won't be perfect, though, since the HDMI is likely widescreen and your eyes are square(ish) format, so there will be top and bottom crop to some extent.

content: One obviously has adjustable interpupillary distance. Not sure about the other. A fixed PD of 62 mm is common and may be OK with you. But maybe not. A link to each scope where it is actually described would be more helpful.The second one also includes a 0.5X lens. Not sure where it fits, but such a lens is often used for photography to get the field of views equal.

The second one does not mention adjustable diopter, nor do the pictures seem to show it. That could be an important difference if your eyes are not equal.As for the 20mm v. 22 mm field, I don't see that as a very significant difference. They are both wide field. Lens quality will make a bigger difference. Can you check reviews? Neither description actually describes image quality.In my experience, the only way to decide between good microscopes is to test them out.

content: The KSGR station with the built in psu can deliver up to 120W. Are there any T12 tips that can actually take advantage of this?Does the default ksger firmware limit the wattage to 70W by default?The following tips are some of the bigger tips that I can find: T12-1401 1402 1403.Are there any other tips which would use more than 70 watts?The Hakko FM 203 has an output of 140W and it also uses the T12 tips.

author: ygi
author_rank: Regular Contributor
timestamp: September 24, 2022, 11:26:55 am
content: T12 tips are all 72W. So ksger clones with 120W supply are just marketing. Granted you may want a PSU with a higher rating when it comes from a questionable manufacturer.FM-203 is a dual tool station. You can either plug 2 irons or hot tweezers but it still can't deliver more power per tool.

author_rank: Super Contributor
timestamp: September 26, 2022, 09:18:13 pm
content: As ygi said, the T12 tip rating is 72W, and in reality its going to use at most 50-60W or so.There might be some value, if you enjoy hacking the station, in adjusting the 24V up to a higher voltage, to hit 72W+. But you'd have to check a number of parts to ensure they are compatible, and accept the risk of tip burning up.FM203 supports the FM2030 handle and T22 tips which are rated for 140W.

Welding is a pain, tips oxidate and when heating element burn out I was unable to solder since the only replacement I've found are from China (1 month to wait).I'm looking for a branded one to be able to find quality and original parts when I need.My budged is low, no more than 130euro (I know, is very low).I've found this two interesting soldering stations:- MULTICOMP PRO MP740888 EU 110e- Used Weller WSD81i 130eAt work I'm using Weller WSD80 and it's very good and I like it's tips. What I'm worried about is price for replacements. Heating element is 150e , and this unit is used. I don't really want to spend twice the price. Also found some users that had problems on sleep mode. I like Weller, but without warranty could be a very expensive brand.Multicomp is a Farnell brand. Cheap, replacements are always aviable, each tip have it's own heating element. Also it's new entry and I'll have warranty. But tips design (shape and dimensions) and "build in" heating element are new for me since I'm used to smaller Weller tips.I'd like to try Multicomp, but I worry about it's possible low performance (just a supposition based on it's low price). At same time I would go to something I know like Weller, but since it's used can become a piece of junk really fast.Any opinions?

content: So i am thinking of buying a proper soldering iron and hot air gun. My budget for both is about 100-120$ (equivalent) so i looked for 2-1 s. I intend to use it mostly for my boards and occasional rapier here and there. My current station (some cheap chinese one that seems to be low power) has only the iron and is with a large tip that is sort of damaged (from learning and potentially mistakes) well for large tht and de soldering them is fine but i am starting to get more into SMD and i simply cant use this one. [+I am thinking of doing a leap and starting to use some simpler BGAs since they seem more available].After some market research I found 4 options but since i have no idea if they have common problems and googling didn't.So here is what i found, all are at lest 2 in 1 and have a temperature range that maxes at 480-500C:Gordak 952(+A version that is without LCD) with 60/240W iron/air power (with this one i did work a few times with hot air at a friend)Gordak 868D similar to above but lower powerBakon BK701D 75W iron powerProskit SS-979 60WJCD 8808 80wPlusivo 3 in 1 (also has 30V 5A adjustable power supply) (i also used this a few times)Well i am also open to other suggestions.Another important point is the tips that they use i know there are some standards out there but.... my knowledge here is nearly none. All i know is that i need a thin one for SMD stuff and a larger one for THT (or it was the one with a cavity in or for SMD ICs ?)Also i can potentially replace the hot air with a hot plate since I was considering making one for a while (or hacking a cooking one).NOTE: since i live in Romania amazon and some other intentional sites come with import taxes (an potentially customs taxes, not sure but i know a few that needed to pay taxes for some small items so for large ones it may just be )PS: this is my first post so i am sorry if i didnt follow some format that i dont know off
