как подключить фен от паяльной станции
10/10 very good
I love these budget station and iron projects my ruski commrade!
Hi!
Bough the dimmer and the heat gun. Hooked it up. Problem is, that it is hot enough to melt solder at the very lowest setting. Turning it up makes it too hot. So not much ajustment possible with this. My dimmer works fine with a light bulb.
What can be wrong?
You should try to adjust the small potentiometer with a screwdriver. Be extremely
careful don't touch any metal part of the dimmer when it's connected to
the high-voltage line. See a wiring diagram here drive.google.com/open?id=0BwsaCaa887AuSHB0MkhySk5jZjA
Ok. Well I cant get it down to 100 degree celcius is the rework station 858. Usefull when doing schrink tubes. When turning the potmeter using a light bulb, I dont see any difference.
GRACIAS @SergeiKrasnikov !!!!

Can i use the same dimmer for lower voltage? example 0-30v?
I think the dimmer could work because a typical TRIAC has gate threshold voltage/current about 1.5V/50mA. en.wikipedia.org/wiki/TRIAC
DC PWM s.aliexpress.com/RvMBV36F
However there is a DIAC. It's used as a trigger. And I don't know its breakover voltage...
Can someone tell me : connect dimmer to 220v, connect gun to dimmer, regulate power with knob. And thats it? Thanks
Ok, maybe this can work: 220v to dimmer and in ac dc converter. Then dimmer to gun and frim dc to dc dimmer for fan speed. So i can make a box with ac input to all three devices and make output to gun on frint side with 2 knobs for regulating temperature and fan speed?

With entire 858d hot air rework station costing only $35, I don't think it's worth the trouble to make hot air reflow station using just the handle.
Great. Just finished building one. Did not connected the thermocouple wires as I do not
have a sutible meter but nevertheless works great.
Thanks Sergei
How do you keep the temperature stable?
Really great
In modern smd components that are in double or more layers pcbs one general rule is that heat it until the solder melts and remove the component.So exactly temperature adjustment is not needed because it is a handheld tool and can vary manually the distance from the component and the delivered heat to the pcb.As long as temperature is not in crazy limits above 500 C to destroy pcb or the heating element itself then everything will work fine.Great inspiring projects and i give you congrats.
How many voltage u start the dc pow supply?
Why do so many people heat the parts they want to salvage from the upside? Don't you damage the components less when heated from underneath?
i think 220v 2000w dimmer is enough right?
I think youre better off buying the whole set that making youre own... It costs arround 37 dollars with shipping.
Hello, English is very good. I made the final assembly on this principle, you help with voice acting in English. I am also ready to help your channel in TH-cam.
Why so many wires?
I have Eruntop 8586 D + stations from aliexpress. Hot air gun set to max blows very poorly. Will the hot air gun blow stronger by replacing the potentiometer on the motherboard with more / less Ohm?
the boost converter what used for?

I'm thinking about building one with an old laptop power brick similar to a Saike 8858.
In my opinion, the problem with the system as shown is that this gun is designed for a cool down timer (the reed switch). This is needed so the heating element has air flow for a few seconds after shutdown. Larger heat guns don't have this kind of feature, but they are usually made of ultra high temperature plastics. Heat guns also have more bulky air insulation space between the heating element and the body of the unit, I imagine they also have a lot more mica insulation than this little guy. The heat guns I've taken apart have a lot more mica than would fit inside this compact design.
What's the purpose of the power brick? Heat gun runs on mains voltage.
hello sergei...thanks for the video...what is the best circuit with temperature control...one that has led display...thanks...and also how to connect the temperature display....do i need an 8 pin aviator plug for this hot air handle? the hot air handle has 2 thermocouple wires. how do i use the thermocouple wires to control the heating element temperature. thanks.
Once i thought to buy only the hand held part and make my own controller,display fan and heater drivers,but the price of the complete tool is 40-50 euros and ready-with the help of some luck-to work avoiding any other mess for code writing and the assembly of components.It looks powerful 700w and already i have ordered it expecting to arrive.
I am in max 786 bloyar how to repair max 786 bloyar handle with filament
How is the reed switch implemented to cool down the blow gun ?
If one wants to have the option of auto cool down for the gun with the use of the reed switch wire in this porject, I am unable to understand as to where would the single reed switch wire connect ? the second wire is however connected to one of the thermocouple wire ... i am unable to imagine/guess the circuit to have this implemented.
Can somebody shed light on how the reed switch wire could be used in this DIY project ?
thank.s
cmon 20 usd you can buy one, whats the point?
Great
Just buy also handheld temperature gun to know the rework station temp.
Hello mijn name is john from nederland. Can i conect temperature display on this project. Thank you
Maladets! Esli Ja ne mog nayti i pasmatrel tvoe video moj fan budet tocno muzir...Patomu sto nikito ne ponimyut kak on rabotatet..spasiva dorogoj
Вот чтож мне раньше не попалось это видео,закажу диммер попробую подключить ручку подобным образом.
Good project. The DC power supply looks like Soviet era unit, I think I saw 0-30V. And it looks like the analog V indicator was replaced with segment display. Please do a video about the power supply.
And if so then the power supply maybe has to last more than eternity.
where the fan noise ?
Ну и выговор у Вас однако!? А не лучше на русском...А так интересно!
where s fan noise ?
Very very nice. I will try to build one, specially since I don't need too use this kind of tool very often.
What about air flow control? I am guessing that DC voltage (24V) regulation would enable fan speed control. Is that correct?
That's correct.
For example,
1) if you have 12V DC from a PC power supply, you can use a DC-DC boost converter to increase the voltage up to 24V. By doing so, you will get the fan full speed.
2) If you have 19V DC from a notebook power supply and you want to lower the fan speed then you need a DC-DC buck converter to decrease the voltage.
can i connect the heater wires to 230AC directly, what can I do if I have no dimmer?
or use a relay that is 250AC capable and swithc that on and off?
Thank you for sharing your intelligence with us Sergei!
So, this 220v dimmer could work at 110v?
aitvochon
Yes. The dimmer shown is actually the same as any dimmer used in household dimmer wall outlets as well. You can pick one up from your local hardware store. Although they will cost more than the modules from China, and they are not as pretty.
Hi there nice video really a money saver but i m interrested do i need an external air supply with this handle? Greetings
+Josip Jurišić this 8 wires handle already has an internal fan. You don't need an external air supply.
Sergei ,today i receive the same dimmer as yours ,but no working...what can i do??
Check your dimmer: connected to it just a light bulb 220V. If the bulb lights up, your dimmer is OK and you'll have to open the gun and check wires to resistance. (abaut 60-70 Ohms between them)
какой английский, прям слов нет
nice project! can help me to measure the voltage in the Temp Sensor between off and full temp?im planning to attach it in arduino so i can display the temp value, thanks
You should check out my article e1ectro.blogspot.ru/2017/02/diy-desoldering-station-for-25.html

Привет. Я в электронике иногда путаюсь. Объясни пжл, почему диммер AC, если используется DC бп и конвертер? Я планирую использовать старый БП от компа, но что-то запутался почему диммер на AC? Или это неважно?
Кажется понял. диммер работает от розетки на 220, так? тоесть нужен БП и розетка..
HEATER works to "high voltages" Alternating Current (AC110-220V & regulator)
FAN motor runs at "low voltages" Direct Current (DC12-24V & regulator)
Yeah, At first I thought that dimmer is connected to DC voltage as well. Now I see there's two different electrical sources.
Thanks sergei
this is good., thank you friend.
i'll make one thanks!
Very creative!
you need to regulate the fan speed
but how to regulate it
Potentiometer
hi, can I know the heating element is running on Ac or DC voltage, I intend to convert my soldering station to add a hot air soldering function to it
For a heating element It doesn't matter if your current is AC or DC. As long as you deliver the same power to the heating element (P=I*V).
how many watt does the heating element need ? i have a 48W soldering station with temperature control.
I don't have the proper equipment to test the power consumption of the heat gun. But I think your soldering station can't deliver enough power to the heat gun. The heating element resistance is about 60 Ohm. The typical soldering station max voltage is Vmax=24V (DC). Therefore P=I*V=V^2/R = 9.6 W. But typical heat guns specifications claim that their power is about hundreds of Watts. So It's not sufficient.
How sync this thing with an arduino and you've got a good soldering station.
Actually I made a breakout board of a soldering station for arduino. In the near future I'm going to cover this topic. Here you can check a schematic and a PCB design drive.google.com/open?id=0BwsaCaa887AuY2VnWTZYSUpFSDg
This is cool! I was thinking to order PID controller for temperature control and variable DC for the fan speed control and then basically have something similar to 858 station clone, but this would be very interesting project to build.
hey with arduino you could make a full automatic bga station:D
Fantastic job Sergei!!!
Друг, твоё всё видео познавательное, можешь-ли ты его снять на русском. Заранее спасибо

nice project. Congratulations. Thanks for sharing
Is it possible to just plug this in a hakko soldering work station? I.e. Hakko 928.
hentai nat
I wondered the same thing myself. I don't think it will work because this unit has a heater coil resistance designed for mains voltage. The Hakko irons run from a step down transformer to power the heating coil. The thermocouple voltage of the iron is also calibrated on the ones with temperature readings so this would not function either.
Upcycle Electronics tnx, I was just wondering if we could utilize the sensor for the heater.
hentai nat
If you look up the channel KainkaLabs (no affiliation) and look for his 2 videos on the Atten Digital soldering station he reverse engineers the heating element circuit. The Atten design is basically a cheaped-out Hakko. It incorporates the themocouple measurement in series with the heating element instead of using an extra set of terminals like the Hakko... However, the measurement part of the circuit is very similar. The Atten design is just measuring the temperature during the PWM off cycle instead of having a continuous analog measurement available for the microcontroller to sample. The measurement circuit is rather simple. It's just a few 1% resistors and a LM324 op amp. Not that you want to build this circuit...
Personally, I'd look into ways of measuring the temperature independently. A thermo voltage is usually measured through the mA range on most multimeters. You need a microcontroller to scale this to a temperature. Alternatively you could just note the scale visually and use a simple $0.99 led Voltmeter from online vendors. There are also cheap units like the MH1210W that could do far more for less than $10. The thermocouples used in these things are just typical cheap K-type designs. The only real issue is calibration as different thermocouple designs will have different properties such as resistance that must be scaled at some point along the signal amplification chain.
You might even be able to take your station apart, duplicate the analog temperature circuit with it's own calibration potentiometer. Then Simply add a switch that shuts off the Iron and sends the new temperature circuit to the MCU in place of the original.
If you watch the KainkaLabs Atten videos you will see the temperature readings aren't exactly true temperature readings anyways. They are more like a scale that requires some 'understanding and translation' by the end user.
