content: Hiya. So, I've decided to buy some tools for tinkering with electronics - nothing too complex (hobby and maybe some basic motherboard repair). I've read on electronics forums (here included) about the knockoffs that work with the Hakko T12 tips. After some browsing for them at chinese sites, I got a bit overwhelmed at so many options. I'm usingthisshop for reference on models (completed station kits).* From what I've seen, there are some different brandings form them, most notably Quicko, KSGER and fDXC (?). Is there any difference in quality between them?* Is there any practical difference between the STM32 and the STC models?* What are the advantages between STM32 revisions?* Does the LED versions refresh the shown working temperature (I don't know even if the OLED versions do this)?* Are the models with external PSU more reliable than the integrated ones?* How reliable can I expect one of those to be?* I've seen fromanother shopthat there are different "gradings" (?) for those tips. Assuming they are all generic, would a "premium" (lol) fare better than a cheaper one?* Are all they "ready to go" or I should worry about anything (wires, caps, etc)?* And last but not least: Can I get anything better on this budget (50-80 USD shipping included, considering I live in Brazil and everything here is extremely overpriced)?Sorry for that many questions, it's just I can't really decide on what to buy since I'm pretty green on this. Been a long time since I last played with electronics and I'm raring to go back for it.

content: Quote from: LeonR on March 27, 2018, 10:32:57 pmQuality will always differ, housings, used components, tip brands etc, but in the end all will do samethingQuote from: LeonR on March 27, 2018, 10:32:57 pmYes, STM32 is 32 bit and more capable processor than STC.Quote from: LeonR on March 27, 2018, 10:32:57 pmThey both are fast refresh and show the current temperatureQuote from: LeonR on March 27, 2018, 10:32:57 pmDepends, but if you can have the both options opt for it, always use a proper 24v psu, so i recommend DIYQuote from: LeonR on March 27, 2018, 10:32:57 pmWill depend on quality of the board and psu, the whole system is all separate pieces (psu + board + handle + handle pcb + tip), if anything broke is easy and cheap to replace but they sould not break so easy and the station is dead simple.Quote from: LeonR on March 27, 2018, 10:32:57 pmYou have to see what is included on the package, STM32 is more expensive than STC, and all extras will care, quicko is a good store to buy these things, inc. tips.Quote from: LeonR on March 27, 2018, 10:32:57 pmIf you are ok to DIY i would recommend, lose wires and connectors are bad and cause problems, direct solder everything and problems gone.Quote from: LeonR on March 27, 2018, 10:32:57 pmOn that budget not really, you can go for a TS100 or spare some more money and upgrade for something better. If this is only for hobby and is your first station is a good bet, cheap and functional.Quote from: LeonR on March 27, 2018, 10:32:57 pmYou can also read this:https://www.eevblog.com/forum/reviews/(tip)-best-budgetcheap-soldering-stations-and-tools/About importing to your country you can buy part by part and customs will not touch that small value (DIY)

content: If you are on a budget, try the Bakon 950D.It also uses Hakko T12 tips.Any clone T12 tip will be poor quality. Read through some threads on this site about T12 tips. Get genuine Hakko tips if you can get and afford them.

Haven't seen discussions about its internals, so that made me a bit wary.There is a mini station by Goot that also caught my attention, the PX-501AS. Quite simple one but it is japanese made so overall quality might be on another level. It's a bit more expensive, but I'd give the extra 20 bucks for it - quality is pretty high on my list.

content: I'm using a couple of Quickco T12 stations from Aliexpress. One DC powered one and one mains powered one. They sell completely assembled units and kits.Some replies:1.From what I've seen, there are some different brandings form them, most notably Quicko, KSGER and fDXC (?). Is there any difference in quality between them?- I can only speak for Quickco ones but they have been pretty good so far. Reasonable quality for the money. The mains powered units need a bit of rework to be truly safe if I'm honest. I mostly use a DC powered one that runs off my comms power supply.*Is there any practical difference between the STM32 and the STC models?- Not really. There are some dodgy ones which latch up and heat the iron tip until it glows red through. The Quickco ones don't do that.*What are the advantages between STM32 revisions?- Not sure. Not sure I really care*Does the LED versions refresh the shown working temperature (I don't know even if the OLED versions do this)?- I use the OLED ones.*Are the models with external PSU more reliable than the integrated ones?- If you can get one to use with a laptop power supply it'll be safer than the other ones, but you will lose grounded tip for that.*How reliable can I expect one of those to be?- I haven't had any reliability problems yet.*I've seen from another shop that there are different "gradings" (?) for those tips. Assuming they are all generic, would a "premium" (lol) fare better than a cheaper one?- I only use the cheap K tips - they seem pretty good. I haven't got through the first one yet and I've done a ton of soldering yet. No problems with oxidation or reliability at all. I tend not to swap tips around though which is what kills them (and the Hakko ones!)*Are all they "ready to go" or I should worry about anything (wires, caps, etc)?- The built ones are ready to go. The kits you will need another iron to assemble with.*And last but not least: Can I get anything better on this budget (50-80 USD shipping included, considering I live in Brazil and everything here is extremely overpriced)?- I doubt it. In comparison, my "other vehicle is a Weller TCP". The T12 honestly runs rings around that and it was a $300 iron.The main unit I use has been somewhat customised so I can run it off 13.8V comms supplies and car batteries offline. I bought a Quicko 12-24V DC kit and put it in a larger case with a cheap 150W (hahaha not likely) boost converter. That takes 13.8V in, steps up to 24V. Iron heats in 5 seconds!Buy the version with the blue 9501 handle - the handle is much better!Some pictures of my Quickco unit (customised):

content: Quote from: bd139 on March 28, 2018, 02:51:52 pmCool! There's a lot of space left inside of it. I assume you can also use a laptop PSU on it - does the converter works within a range or is it 19.5V only?@topic: I've decided to go for a TS100 for now, especially for the compact size and (apparently) better quality tips. Sometimes having way too many options (like those T12 clones) only makes it more confusing. Since the TS100 is more or less a standard (open-source and such), the chances of going wrong with one are smaller. I've also grabbed a 24V 5A laptop PSU, which is a bit overkill but I really don't like using power supplies to their limit (as I would on a 3A) and a couple extra tips. For anyone wondering, here's the ones I've bought:TS100 + 2 tips (MINI brand)C1 tipB2 tip24V 5A 5525 Power SupplyThanks for everyone's answers!

There's already some motherboards (from my collection of old computers) that need recapping that I'm going to use as guinea pigs for my rusty soldering skills. At least I won't be able to complain about having to use a improper tool for the job

content: TS100 is a good choise, you will not regret. And you can improve by redo the cable with a light and flexible silicon cable (1 or 2m). The power adapter cables are not great for this use.

content: 1 reason to choose STM32 over STC is custom firmware, I hope more developers get in on the game and create a really powerful custom firmware for these units, here is one of the first to do so:https://www.eevblog.com/forum/reviews/stm32-oled-digital-soldering-station-for-t12-handle/I ordered both a TS100 and a STM32 OLED soldering iron and I cant wait for them to get here!!!

content: As an update, I've received my TS-100. I grabbed a 24V 5A power brick from Delippo, also from Aliexpress. It is the quintenssential soldering station on a budget without sacrificing quality - I can get some pretty fat planes melting in little time with it. Just waiting for my C4 and K tips to do bigger stuff (I own a D24, I, ILS and C1 ATM).

content: Quote from: LeonR on June 18, 2018, 12:45:25 pma few weeks ago i also received my TS100 and for the most part i really like it.. It's not perfect but then again nothing is. it all depends on your use case.My whole thought behind getting this iron is learning / fiddling and doing something else besides working/studying (even at 42yr)...i did get 3m of flexible two core wire to make an extension cable, will be making it 75cm to 1m max..but i wanted to compare the TS100 with a compact station that accepted a wider range of tips and did not have a power supply. i don't like the idea of a cheap power supply next to me on my desk..so i got this station but i opted for the more expensive aluminum handle.Here is the cheaper listing.https://www.aliexpress.com/item/-/32850601075.html?spm=a2g0s.8937460.0.0.25b22e0ePZTcjjThis would be a station that Dave could review.. he's always saying i won't review the TS100 because it's not a station for a bench..well i don't have a bench just a desk where i do everything work/study/solder and so i remove / clean up every time i'm done..This will have to do until i get a bigger place..

content: i was talking to VoltLog about the vid he posted on youtube titled "Voltlog #85 - STM32 OLED T12 Soldering Station".Where he mentioned that a hall effect switch would be preferable over the currently used vibration sensors in these irons..In his vid he said he would look in to it..my question:Have you looked in to using a hall effect switch? instead of the currently used vibration sensor. after watching this vid it seems that there is a part on the board that works with the switch??https://youtu.be/W5HECI1L3dg?t=53s﻿End of question..His Answer:Some investigating should be done to see if the board expects a continuous low/high signal on that switch input or if it expects just a state change to trigger the timer. It was my intention initially to replace the switch but unfortunately I abandoned the idea due to lack of time.﻿End of answer..my answer:that's well beyond my current ability and knowledge not to mention the hardware needed perhaps oscilloscope and such. perhaps someone on eevblog has the hardware / skills to do what you suggest.. of course one could simply mod the iron and see if it works what's the worstend answer.if anyone has the skills / knowhow and the hardware and would be willing to try it out.. the result could be awesome..

content: Hi guys so i just finished doing a temperature comparison with the tools i have between the TS100 and the KSGER STM32 mini..So what did i use to compare temps?i bought a daniu fg-100. As you can see in this youtube comparison between the real Hakko FG-100 there is no real difference..Of course there is no certainty in life.. Also i just received to pics from the seller that are suposed to represent the manual for version 2.01. i will post them on my imgur and link it here for refrence..So the temperature comparison was surprising to say the least. when the seller (official KSGER store) told me they use high end equipment to test the temp i began questioning my assumptions...i put the TS100 on 300c and tinned my D24 chisel tip and measured two times. the meter said 271c that's a difference of 29ci did the same with the KSGER STM32 mini put it on 300c tinned the T12 tip and measured two times that showed me 274c so that's a 26c difference..So conclusion?? assuming two irons with two different tips both have an offset of around 27c is highly unlikely..While typing this i thought to myself "what about the censors?" so i replaced it with a brand new one..And wouldn't you know itboth irons now measure 300c on the dot.. give or take 1 or 2c....

content: First conclusion now both irons show exact 300c on display and temp meter. (after i fixed my blunder and did a proper measurement)..Connecting the KSGER to my new grounded meanwell GSM90A24-P1M the whole unit seems to be grounded..i measured this with my multi-meter on continuity from tip to third pin.The station uses the same 5.5*2.5 jack (i bought spares for nothing hahahaha did not trust the Chinese)The Aluminum handle feels way better then holding the TS100 pen like shape..the silicon is burn proof..but not as flexible as my brymen probes..The whole unit does feel a bit cheapish but then again it is..then again every part on this soldering station is replaceable for cheap so i'm pretty save..I would even go so far as to state that this unit is probably the better choice over my TS100 only one negative i can say about the unit is that it's not openSource as far as the seller is concerned (that's what he told me) .. Then again i have no idea what this is for then??https://www.aliexpress.com/item/Emulator-Downloader-Programmer-ST-Link-V2-STM8-STM32-OLED-DIY-Kits-T12-Electronic-Welding-Iron-Tips/32820881304.html?spm=a2g0s.8937460.0.0.e8902e0eB7NNWFcould it be that the unit i have is password locked (that's what the seller is saying on his site..All that aside.not everyone is interested in flashing his / her soldering iron..it's fast heating small works with the same power supplies as the TS100. Plus it has a proper silicone soldering handle, everything is grounded.Also you have an array of tips to choose from unlike the TS100..in short getting this station with a cheaper handle when it's on sale will give you a good backup if and when you need it..you don't need to spend the $70 i did on it
