content: HiI've got a Weller WTCP-S iron which needs new tips. I'm probably going to buy a Weller PU-81 (I found one second-hand with the iron as well) since it is temperature controllable.On my current tips it seems to say "PT-something" (it's hard to read), so I guess I should buy the PT type? There are ET, PT, RT, MT LT... Why do they make this so complicatedI also need a hot air station (I have been doing a LOT of desoldering with iron and wick... so yea it is time), I found something called Toolcraft ZD-8908 which is affordable, or a second-hand one called Atten ST-862D. The Weller ones are pretty much all over $1000.My questions:1- How to know which Weller tip fit which Weller iron?2- Is the iron dependent/different for each Weller power unit? F.ex. the PU-81 and WTCP clearly have different plugs - do their iron fit different tips then?3- any feedback on the hot air stations?Thank you!SimonPS: Just rewatched Dave's series about soldering equipment (here:)I also realized this video series is now 11 years old, so when Dave says "oh it's like $100" I thought "great!"... Ha ha yea prices have changed

content: I bought myself a JBC clone.https://nl.aliexpress.com/item/4000073506197.htmlThere are others and with a bit of searching cheaper, but I like it very much. Also have a weller with temperature control. Looks like the one on your photo, but with a control knob on it. Now only use it when something really coarse needs to be soldered. The Jabe works great. Heats up quick, changing the tip is easy and allows a wide range of temperature to be set.For a hot air station I have this one.https://nl.aliexpress.com/item/32818030316.htmlWorks very well for the stuff I do, which is hobby related electronics, not full time (re)work.

Alternatives to Bofa T1 for soldering tip fume extraction? - Page 1

content: Hi,I recently got a JBC soldering station, for home/hobby use.I also purchased a small on-tool hose (JBC F3435) that's meant to suck solder fumes directly from the iron.I already have an existing fume extractor (Kingsom KS-180), that has a 50mm hose. (Recommended from one of theEEVblog YT videos)However, I've now found out that there isn't actually any adapter to go from the 50mm hose, to the 6mm hose from the soldering iron itself - apparently you need a special "high-pressure" fume extractor, like theBofa T1.Does anybody know of any other cheaper alternatives, for these high-pressure, or single-tip fume extraction machines? Or any way at all to use an existing normal 50mm fume extractor? Is it just a question of higher pressure in things like the T1?Thanks,Victor

content: If you can 3D print an adapter, I would try that first, see how the performance is. It depends on the static pressure performance, and I don't see spec for the kingsom.IMO iron mounted extractors are crap compared to a properly oriented hose. But in certain situations (very large PCBs) it might be required.If kingsom alone is not good enough, you can buy a centrifugal blower, and use that to provide the static pressure, which would then feed into the kingsom unit for filtering.https://www.aliexpress.us/item/3256802760725913.htmlhttps://www.aliexpress.us/item/3256801349476882.html

content: An 858D type should be plenty, easy to use/control and ok for general electronics. You can also buy an appropriate sized tip and squash into shape. Don't leave these plugged into the wall as they could turn on during failure. It pays to inspect the stations mains and ground/earth wiring as well. But otherwise a good tool for it. Shop around on price.

content: The really cheap hot air guns can be a bit of a fire hazard. They're always one fan failure away from combustion since the element is burning up much more power than it could ever withstand without the airflow.Some of the Atten 858 clones have a DPDT switch where one set of contacts is fan on/off and the other controls the heating.So if one side of the switch fails you can lose cooling but it's still running the heater.As long as you're in the room or nearby its fine, but don't leave them unattended.
Any idea what kind of VHDCI / SCSI connector this might be? - Page 1
Forum section: electronics / general

timestamp: January 18, 2023, 12:58:34 pm
content: Hey guys,I am looking for a certain type of very-high-density cable interconnect (VHDCI) SCSI connector (or a cable which has this kind of connector attached) but can't find any information about it on the Google-able Internet.Maybe some of you guys could give me a hint where to find it. I have attached some pictures below.The connector I am looking for is used in a PCIe to PCI Expansion Chassis from Sun Microsystems. The expansion chassis was sold during the early 2000's as "Sun Microsystems Netra E1". I believe it was used as low-profile solution for rack mounted servers.According to the Archive.org, there was a deal in 2002 between Sun Microsystems and a company called MAGMA (now part of Avid, famous for its professional video editing solutions), where MAGMA would deliver the off-the-shelf components for Sun's PCI expansion boxes. The PCIe to PCI host card was made by MAGMA, the chassis was made by Sun Microsystems.I am using such a Netra E1 expansion chassis for my PCI oscilloscope cards but the cable which connects the host PC card to the expansion chassis is very short (about 30-40 cm, 1 ft) and I can't move the chassis around. Extending the cable to ~2-3 meters would be much more convenient because I could place the chassis on my workbench instead having it in my proximity. While powered on, the server rack fans are extremely loud in order to provide the cooling airflow (which is necessary for the PCI oscilloscope cards).The PCI I/O cable has the Sun Microsystems Part No. 530-2977-01 (REV 01, 8425/0113). It's listed inside of the Sun Microsystems handbook but there are no further details about its construction. One end of the I/O cable has a "standard" 68 pin SCSI VHDCI high-density connector. Those were also used by other companies like HP, Dell, IBM. It was used it in their servers during the early/late 2000's, too. It was probably used for attachment of external SCSI mass storage to the servers.The connector I am looking for is shown in the pictures below. It was made by Molex probably in 2002-2004 and has two rows with 60 connectors each = 120 connectors. I've looked inside of the connector and they adapted the 68 pin VHDCI to the 120 pin connector. Most of the connections are not populated. There might have been similar connectors from companies such as Amphenol, Centronics or Foxconn but I haven't found any suitable part number.Another possible solution would be removing the existing connector from the short 1ft cable and attaching it to a longer one. This is a little bit risky for me because I don't want to potentially trash my good/working cable.Any idea what kind of Molex (Amphenol?) SCSI VHDCI connector from the early 2000's this might be?

content: Hi Guys,I am trying to find a solution for my parents and their communication, and was hoping someone could help. My mother has a degenerative neurological disease like Parkinson's, that's impacted her speech, but not her hearing. Her speech is slurred and soft in volume. My father has poor hearing, but has good hearing aids. In most scenarios, they are trying to talk to each other (either at home, or out and about), but the low volume of my mothers speech combined with background noise and distortion, makes its too difficult for my Dad to understand, and he ends up needing to put his ear to her mouth to close the distance.We have been to a speech therapist who trialled us with the a voice box amplifier, where the amplifier/speaker was worn around the neck, but the distortion of this device made it too difficult for my Dad to listen and understand, so it was a fail.When my Dad has his hearing aids directly connected to the TV, he can hear fine. So now I am thinking some type of wireless intercom headset would be ideal. I have looked at something like the Sena Expand (https://www.sena.com/us-en/product/expand) but this model does not have any adjustment on microphone sensitivity. Without trying it, I am not sure Mums voice volume would trigger the threshold on the microphone audio switch.Any ideas on other products that might do the trick?

If you go to a hearing specialist they can help to choose a good hearing aid (and very importantly, adjust it to the needs of the individual user) for the best results. Apparently the difference between a basic hearing aid and a professionally fitted and adjusted aid is enormous.

Microscope arbor size, 25mm or 32mm?  - Page 1

content: Apologies if this is a little long, just wanna cover my usecase, and put out what I already understand and what not. So responding can hopefully be less of a hassle for you guys n gals.I'm getting an Eakins (same form factor as the common AmScopes) trinocular/simul-focal microscope and adjustable focus-holder for it, primarily for microsoldering work. I intend to DIY fabricate a mounting bracket for it to attach to a sturdy "gas" monitor arm I have lying around, for the time being. Getting one of the dedicated for-purpose ones is just way out of my budget for now. But I'll probably experiment with different mounting solutions as time goes on.I've only really worked with the common double boom stands before (what was already in house before my arrival), and those had 32mm arbors. But I see there's a very significant price difference between microscope focus mounts, and other mounts and parts, between 25mm and 32mm versions (the latter more costly). Anyone know why? Is there some significant difference to them other than "bigger number more better"? Is there some standard I don't know about? I do see 25mm steel and aluminium pipes are way more available and cheaper than 32mm, should I want to DIY those kinds of mounting parts later. 32mm connecting parts seem to be less offers for, so a bit "worse" for both cost and availability. The microscope head itself, even including lenses, a meaty camera and ringlight, is just on the thick side of 3'ish kg. Is there notable less flex in 32mm pipes and rods, vs 25mm (within this use and scale context)? I'll probably never use this setup for any larger magnification than 90X, most often 15-30X, so I'm don't know if any rigidity benefit would even benefit me..?Anyone that have used / worked with both, or otherwise have relevant insights to share? (And yes, afaik I understand I can make a "spacer"/solid bushing insert to fit a 32mm focus mount on a 25mm arm/boom etc, if needed. But I'm not equipped to go the other way and drill out a 25mm mount.In advance, thank you for your time.

content: I don't know any use case where airflow below 5-10l/min can be advantageous. Below 20 l/min is quite niche use and most likely it will be fine with 20l/min anyway. For SMT soldering I use around 60 l/min in most cases, 120 l/min for heatshrink and fast desoldering of something larger. Atten ST-862D is pretty good apparently. However Atten is known for selling a lot of low quality equipment, but lately they seem to be targeting higher price segment with better quality equipment. If you want to save some money ST-862D is a good choice. I don't see a reason why you would chose Xytronic over Quick or Atten.

I guess the T-80 refers to it being an 80 watt iron.The first soldering iron I owned was given to me in the toolkit provided by my employer when I started as a trainee technician in 1965. It was an Adcola 19 watt iron. I used it for years until I bought myself a Weller TCP1 in about 1971-2 which I still use - more than 50 years on. It cost me nearly a week's wages.

content: Anyone have a neat solution for storing Weller LT tips?I have a bunch of LT tips for the WSP80 iron, a half dozen different tips for the DXV80 desoldering iron and I think 4 tips for the HAP200 hot air.Smallest divided storage box I can find is 7.5" x 5.5" (24 slots).Amazon example. The above will work but I was hoping for something smaller and more durable, IME the clasp or the hinge can fail on these cheap boxes pretty quickly.There are some interesting3D printer designs. The tips for the WESD51 have a long shaft that fits into the iron, whereas the LT tips are much smaller and have a flange.I'll probably go with the Amazon storage box but maybe someone has figured out a better option?Thanks!

Chromecast 4K alternate USB Power - Page 1

content: I do TV mounting and occasionally have a client that wants a Chromecast 4K connected. To work at 4K it requires using its original USB PSU. Any USB power source other than the OEM will not allow 4K (regardless of power capability). This is fine if the GPO is below and the USB cable can be run to the TV directly, or concealed. However, if the GPO is behind the TV, it needs a bunch of space, or the GPO has to be recessed.I've researched a little if there is an aftermarket alternative. Only references I could find is a home job where he removed the daughter board and hacked a USB cable to the power, and 'Mission USB Power Cable'https://bestreviewcare.com/top-10-chromecast-4k-usb-power/(number 1), but its compatibility is ambiguous.I am really surprised nothing aftermarket exists to solve this problem. However, its become less of an issue as more people upgrade to smart TVs. I'm still curious though.

Having zones of the LED-ring switchabel to control the direction from which the light shines at the target2. Having a rotatable polarization filter in front of the LEDs/lensFor the polarization solution, there is a worst case loss of brighness of roughly 50%.For the switchable zones solution it is dependant on the zone pattern.However... is there one solution anyway superior over the other so that it's clear which way to go?Ok... i could implement both... but i'd like to know your oppinion first

Have not had a single issue with it and have recapped a dozen or more boards with it but I know its just a matter of time before the heating element burns out on it.The zd-915 replacement parts cannot be found anymore..... Seems like the new black/teal green pros kit ss331h and its replacement parts are all thats available now.I would like to order the new style replacement gun but i think the cord has an extra pin. Has anyone took one apart and probed the pins and figured the pinout and modded one of thwse to fit the older beige anesty zd-915 desolder power/vac unit?Any ideas if the heating element is compatible? Id like to replace the whole gun since I think the new one has thermal mass improvements and a glass tube thats easier to remove but if ita not possible to use the new gun im hopeing the heating element can at least be used in the zd915 gun.

content: Not that hard, just the interlocks to detect the vehicle is in park or neutral before enabling it, and then switching the ignition and accessory systems on in the correct order. Most modern vehicles though have the ability to do that built into the BCM already, you just need to turn it on, and it will start the engine, though it will not allow the vehicle to be shifted out of park until you either have the key in the ignition, to allow immobilisor to communicate with the valid key, or the keyless entry does the same. If it is a modern vehicle you are stuck with letting the agents do it, or getting the manufacturer kit, but for older vehicles with no immobiliser (all metal key with no small chip in it) it is simple to install, just need to tie into the gearbox position sensor switch, and connect the appropriate power relays to the ignition switch and interlocks.

The thing is, i would never try to start the car without looking at it from a window, and besides that, the car will not let you take the key out of the ignition until the car is in park or neutral. It's also sitting in a driveway.If that is true would that make it even easier to install?One thing i dont get though, where do you connect the connection that gets past the key so it doesnt need the key?

content: Hello everyone,I recently ordered a cheap S-998P desoldering pump from aliexpress and had selected the 110V version.When it arrived I discovered it was just the 220V-240V version with a Type I plug. To make it "110V", they included a Type I to Type B plug adapter.I was wondering if anyone knows if there's a difference in the S-998P Circuit Boards between the 110V and 220V versions. Since the circuit board is also used on the S-993 series of desoldering guns.I'm hoping I can just use the gun as is, without having to get a step-up transformer. But am confused about the differences in voltage spec since on aliexpress some sellers sell separate replacement circuit boards for 110V and 220V specs.And if it is okay to just use the gun without modification to the power side, can I just chop off the Type I plug and put on a proper Type B plug.Thank you in advance. Sorry if the above post is hard to readthis situation has been a big stressful although somewhat expected from aliexpress.

content: The heater core is different for 110V and 220V, so it might not work. But, plug it in and try, see what happens. Best if you can use a watt-meter to measure the power consumption too.Make sure you do not mark the aliexpress item as "received" yet.If it doesn't work, contact the seller and let them know you received the wrong voltage.

That I haven't tested yet.I don't have a wattage meter at the moment.Update: I just checked. Looks like the seller had replaced the heater core before shipping to me. The assembly says 110V 80W.Thank you for the help.

I am indeed using Hakko tips as the Aoyue are useless. It works ok but I feel I could move to a much better performing one.I am a... demanding hobbyist. I don't mind investing into something better which can last years but I don't think I am ready to invest in a Metcal! I am a bit confused by all the options available around. I've seen poor reviews of some very expensive gear and great ones of very cheap ones.It also feels to me there is a gap between the cheapo KSGER and the Metcal range! Is there anything in between which is good but not super expensive?In fact I was thinking of giving the KSGER a go but honestly I feel I might just waste my money. Very confused indeed. Any hint is appreciated!Thanks!

content: Opinions on these? They are made in Taiwan which I find makes good quality items. I really dislike the disposable Chinese stuff but my budget doesn't run to a Hakko station.I readthis teardown of the LF-8800 here. I also foundthis thread on a pinball repair forumwhich stated that the earlier LF-8000 was pulling 25" mercury on it's built-in gauge. I believe the pump runs on 120v rather than 12v that many of the Chinese units do. 7" mercury did not seem uncommon for the Chinese units on that pinball repair thread.I'm not sure why Zytronic got rid of the built-in vacuum gauge on the newer 8800, it seemed like a good feature. I'm also not sure what the difference between the 8000 and 988D is? They look the same. I see spares for both listed athttp://www.xytronic-usa.comI saw a comment on the earlier thread"I found a couple Open box units at a good price"[referring to 8800]. What would be a good open-box price? I see the 8800 is $347.58 new at Amazon right now.I'll keep my eye open for a Black Friday deal but I kind of prefer the earlier version with the built in vacuum gauge though buying used is always a risk. The used prices on the older units on eBay are pretty uncompetitive with the new 8800.
