[@robstrain2661]

I just stumbled across your video, I am researching this very build. Well done! I love how you care for fit and finish. I also love all the people who have piles on about how "they would have done it better", yet they haven't, have they? There's a lot of trash talk, but no links to their builds.... Like I said, I am thinking about making one of my own and I noticed a couple of things. In most of the other videos; 1. there is NO schematic at all (good or bad). There's, usually no documentation at all. 2. There's usually no prices listed. If you look at the components, they are usually reclaimed, or "harvested " from either dead projects or recycled from someone's trashed equipment. I'm just pointing it out, or picking on anyone (I've done it myself) 3. The only time you see breadboard or PCB is when reclaiming items, see above, lol. If you see videos free on certain areas of the world, they just nail it to a piece of wood. I've even seen no case/covering to components. And no, before the haters pile on, they don't do it off camera. You see in later vids, that it still stands they same way it did at the end of their videos. 4. The care you put into fit and finish. You even used black silicone to match the case. That was the first time I've seen that done in a video. And finally 5. As stated above, I don't see links to their videos...... Again, great work. I "liked" your video and will be looking out for more. Thanks for sharing.

Hello, im interested in building it but i have some questions. -I have problems to unsolder big components with my soldering iron because the temperature drops, will this fix it? -Can I replace the buck converter with a lc7805 regulator? -Can I use a transformer with a rectifier instead of the psu and put it all in the same box? also i hope you can help me with an idea, put a swich in the stand and if you leave the iron there for about five minutes it turns it self off

[@sasiskas]

hello, -if you want to unsolder big components you need a tip with big thermal mass (in other words, you need a big tip), you also need a powerful power supply. I can not tell you for sure if this soldering iron will work for you, because it depends on the size of the components. -yes, you can use a 7805, it is absolutely fine. -yes of course you can use a transformer. I had the same idea long time ago, but I never implemented it...I wanted to use a reed switch in the handle and a magnet on the base. But never found time for it.

With everything being so small and compact, does it have any cooling problems?

absolutely no, if I had used a smaller display and SMD components I could have made it much much smaller. The TS100 for example, has more components and is super compact.

In the schematic, there's the sensor and heater connectors. Does it matter which pins of the soldering iron itself these connectors are connected to?

[@nico8273]

After researching for a while i've been considering to make this build. Taking in account that where i live its hard to come by some of the components i'd start gathering them.(I have a series of questions). 1_The soldering iron I link below its the same you use here right? 2_You change the heating element because of the temperature readout? or because the quality of it? 3_Is there any important change i'd need to make if I wanted to use the soldering iron handle as it is ? (with the thermocouple) 4_ The voltage you step down with the buck converter, works both for the logic and for the heating element? Thanks! and sorry if i might have flood you with questions lol

[@sasiskas]

1. If you mean the link that I posted in the video description. Then yes, it is the same that I use, but be aware...most Chinese sellers on ebay, have multiples sources, so it is possible that you will not receive the exact same model as I did. 2. I changed the heating element, because of the quality. The one that came with the iron was not a ceramic heating element, it would degrade very fast and in general it would perform poorly compared to the one I finally used. 3. Yes, in that case you need to change the schematic a little bit. If you want I can help you (even though I suggest that you upgrade your heating element) 4. It is only for the logic and the LCD, the heating element is powered by 24V. I suggest that you try to make this build, it is a really nice project. I also couldn't find most of the components, so I bought all of them from ebay and AliExpress. If you have any questions feel free to ask.

[@nico8273]

@@sasiskas Allright thanks! I'll try to gather most stuff and when I have almost everything to make it i'll contact you if I have any doubts. Considering my budget is kind of low i'll step down the voltage with a linear 317, I guess the power consumption of the logic board is not that high right?

[@sasiskas]

@@nico8273 An LM317 is also suitable for this project, exactly because the consumption of the logic is very low. It might be even a better solution that the buck converter, considering that the buck converter takes up too much space and makes everything harder to fit.

@@marco-me1uh I don't think so 😉

[@sasiskas]

@@marco-me1uh First of all, this is not only about money. It is mostly about the pleasure of DIY. But still, the one I made is the best value, it cost me 32USD, and you can even make it for 25USD or less if you don't care about the esthetics. There are definitely no decent stations below that price, you can only find stations with analog control, with no display or in best case with a simple 7 segment display that can't display both the setpoint and the current temperature. I will not even mention, being open source, having PID control and being highly customizable. If you just want to do your job, you may even buy a simple iron without any temperature control for 2usd.

[@LuyolaAdams]

Hi Sasikas, thanks for the video. I've done some Googling and I can't figure out why a thermoresistor would be better than a thermocouple for this project. Can you explain why you said "your iron most likely comes with a thermocouple. (thumbs down)."

[@sasiskas]

Thank you for your comment. I should have explained it better. It is not that the thermocouple is bad and the thermoresistor is good. The difference is actually not the kind of temperature sensor that is used, but the heaters themselves (ceramic PTC vs nichrome wire). The heating elements that come with a thermocouple use nichrome wire to heat up the tip. On the other hand the heating elements that come with a thermoresistor, use a ceramic PTC to heat up the tip. The ceramic PTC heats up faster and it is more durable that the element using a nichrome wire. That's why it's better. The reason I referred to them based on their temperature sensors, is to make clear that each kind of temperature sensor needs a different wiring.

[@hedi875]

A really fantastic project, thanks sasiskas. I have completed it and it's working flawlessly. I had (and still have) just one issue : sometimes (while tuning or calibrating for example) the encoder indications are erratic : when right or left rotating it sometimes the values increase and sometimes decreases and some other times jump for instance from 40% to 75% and vice versa . Have someone had this issue or is it caused by a poor quality encoder ?

[@sasiskas]

thank you for your kind words. did you add the 100nf capacitors to the encoder? Their purpose is to prevent this exact problem from happening.

[@hedi875]

@@sasiskas Yes i added them but on the pcb not on the encoder itself (the distance of the cable between the encoder and the pcb is arround 10 cm.). May this be the problem?

[@sasiskas]

Hedi normally it doesn't matter if it's on the PCB or the encoder. Make sure that they are connected properly. As a last resort try replacing the encoder.

[@hedi875]

@@sasiskas Very strange problem... Have checked the connections, to be sure i have also desoldered the three 100nf capacitors and resoldered them on the encoder itself but the problem still remains. I have also replaced the encoder by another identical one (I just have 2 identical encoders) without success. What i noticed is that this problem does not occur when the heater is OFF ie scrolling the main menu or modifying the set temperature while in OFF position are ok without problems. It happens when modifying the power percentage in tuning mode ?? very strange.

[@hedi875]

OK. Now it works much much better. I can scroll all the value without problem (it still bounces sometimes but on the whole it's ok). What i did... : Actually i'm using an encoder mounted on a breakout board (for arduino projects) so i think it has already the debouncing components installed . Therefore i desoldered the three 100 nf capacitors and got the issue fixed. I could after that proceed with the tuning and the calibration tasks and was impressed by the accuracy of the station . I re-verified the tuning and calibration values and everything was ok. Thanks again sasiskas for the project.

The lowest the power of your power supply, the longest it will take for the iron to heat up. Also the lowest the power, the harder for the iron to maintain its temperature in demanding applications (like soldering a component with big thermal mass).

Thank you for your comment. Unfortunately, I didn't draw my schematic for a single layer board. That means that it can't be etched. Also, when designing the schematic on easyEda I didn't cross check if the physical size of the components is the same as the ones that I used from the easyEDA library. Meaning that I don't have any files that can be used for PCB prototyping. If you want you can recreate my drawing,and make it suitable for prototyping

I already have one but I never tested it. For that pcb you need to use specific components with compatible footprint, you can't use just anything you like. I suggest that you use a perfboard.That way you ate going to be more flexible to use different any kind of components, regardless of their footprint.

thank you for your comment. I didn't include that step because it doesn't matter which pins of the aviation plug you are going to use. You can solder any cables to any pins. The only thing that matters, is to know which pins of the heating element are for the heater (red pins) and which for the thermoresistor (blue pins). Feel free to ask anything you like.

[@dannyperry8070]

how can you speed up the heating process

[@sasiskas]

There are a couple of ways by editing the code. 1. Find and edit the "max_power" in the code, values between (0-255) 2. By editing the PID values of the code (it is an advanced method)

[@dannyperry8070]

@@sasiskas Thank you for the great video and I have been studying your schematic. Now to speed the heating process, if you set the value to 255, what will be the max current pumped into the element. What setting would you change on the PID? The proportional? then tweak the other 2 for stability?

[@sasiskas]

@@dannyperry8070At 24v it shouldn't draw more than 4Amps. The purpose of max_power is to prevent your power supply from triggering the short circuit protection. If your psu is powerful enough, you can set max_power to 255. You can just experiment, in the worst case your psu will just enable the short circuit protection and will stop delivering power. PID is a very complex topic, it can't be discussed on the comment section, if you don't have the knowledge, I would suggest that you didn't touch it.

[@justinvanson2743]

How to calibrate? mine will always say it's at 400C and it never says "no iron".

[@sasiskas]

1. You either have a wrong connection. So just double check your connections. 2. Or your station simply needs to be tuned. For the tuning process you can check my video "how to make a T12 soldering station | Part 2" at 8:15. The tuning process is the same for both of these stations. 3. Or you have a wrong/faulty/fake op amp. I suggest that you use an MCP602

sasiskas Ive checked my connections 6 times; the only thing confusing me is the 500k pot. Right now I have pin 1 and 2 connected to eachother and pin 3connected to the 220k. I will try another opamp because this one is from ali.

@@justinvanson2743 if the tuning process wont help..that means that probably there is a problem with your opamp. I got mine from AliExpress as well. I was lucky I guess :) Go for MCP602 it is cheaper, easier to find and less likely to be fake.

@@svsv9 Thank you for your kind words. If you are asking whether the tip is grounded or not, then the answer is that the tip is not grounded. I did ground the tip because is was planning to do something else. But you can ground it anytime. The aviation plug has unpopulated pins, you can use that for grounding. Just connect the spring from the soldiering iron to the ground of your PCB. Regarding the temperature, I don't know what could be wrong...my soldering station goes above 400C. But I don't think that you need more that 350C for phone repair... No you can't convert this project into T12, But I'm trying to make a T12 Iron at this moment...if I succeed I will make a video.
