Youyue 858D+ some reverse engineering + custom firmware

[Shock]

Now I need to get some cheap stuff and improve it progressively, the extreme DIY way!
This is crazy! I have no idea what to buy. Please help

I suggest you read the thread very carefully and if you cannot figure out what to buy by the end of it quit electronics.

wguibas I've got a Yihua 858D if you have a board spare I'd like to grab one as well please.

I have plenty. I had 40 boards made

Thanks wguibas I just received my PCB, looking forward to messing with it.

[wguibas]

Glad it arrived safely.  Let me know how it works out

Thank you robert, my small contribution, a logo to print on sticky label and properly rebadge this:

My highest accomplishment in life so far...

Happy New Year 2016.

Your response motivated me a lot to find and not care about negative things people say to me. Thanks a lot!

I found the following models.

- BEST BST-858D+
- BAKU 868D

The prices are from 29,34 EUR to over 80 EUR.

My question is: Are there different versions of 858D? Are there differences between 858D and 858D+?

I just want to buy the right model to be able to install the board. I would like to buy one board for it, too

Thanks in advance.

Did you read the thread carefully as I suggested?

I was being serious, there is literally dozens of different hot air stations with different PCBs, but there are only two brands/models of hot air station and two micro controllers mentioned in this thread. The PCB that wguibas made (if that is what you want) was for a specific hot air station, which was also discussed in the thread.

I think it's reasonable that you either purchase one of these models or if not figure out what controller the one you intend to buy uses. But either way the whole discussion including everything I've told you here has already taken place in the thread. So you might think it was negative but perhaps you missed the point about reading carefully as I suggested.

To answer your question (specifically) yes and yes many. But unless you're willing to go the solo route I would stick to what others said works.

858D and 858D+ are just labels. They're just the book cover. As the old saying goes, "Don't judge a book by its cover." What's inside could be drastically different. Afterall, a knockoff only has to look and operate enough like the original to get someone to buy it. It doesn't have to be built the same way.

For the highest probability of getting a unit with one of the microcontrollers discussed here, it's best to buy exactly the same brand and model. Even then, there's no guarantee it will be the same, but the chances are better.

My observation is this one the Youyue is the best built of these cheap air stations and it directly takes the atmel chip without need for an adapter board.  The Yihua which looks the sames has much cheaper circuit board construction and needs the adapter board for the samsung chip.

I've also noticed the ones with a removable hand piece cord (screws on) are better built with the atmel chip.

A little while ago, I got a Youyue 8586. This is like the 858D hot air station, but with the addition of a knob-controlled soldering iron.

(What? You bought a combo station? Yes. Since I already have a trusty Hakko 926, for a few bucks more than the 858D, the 8586 gives me a backup iron...makeshift hot tweezers...hot chopsticks!)

Anyway, I was hoping that since the iron portion was analog, that the hot air part would be identical to the 858 and be controlled via the ATmega328. Lo and behold, it is. I haven't yet acquired extra 328 ICs to try out the replacement firmware on it, but that's on the list of things to check out.

So, for now, having the right microcontroller is all the info I can provide as far as another possible device for the modded firmware.

Edit: Fixed typo 8589 to 8586.

Well,
today I got my own Youyue hot air station.

Or - I almost got one:
As you can see, I got a "Uyue". I bought it from a dealer on aliexpress - this one, to be specific:
http://www.aliexpress.com/item/220V-700W-YOUYUE-858D-ESD-Soldering-Station-LED-Digital-Solder-Iron-with-3-Nozzle3/1966416691.html
I specifically asked it it was an original Youyue before ordering and the dealer confirmed.
When the device arrived today I was to be surprised getting this "Uyue"-crap.
I instantly opened a dispute on Aliexpress. Interestingly enough the seller now doesn't use the "Youyue" pictures anymore to illustrate his device as he did up to a few hours ago (probably before I opened the dispute...). He already tried to tell me that Youyue and Uyue are the same.
Bullshit...

When I opened the device I saw the same pcb and components as brainwash already showed in the thread. Only difference seems to be a more recent pcb revision. Mine is 2015.08.21.
Pictures below.
After some looks at the whole assembly I can say: The soldering quality could be worse. At least ground is connected well enough in my device .
Quite irritating is the mains connector just hot-glued into the casing. I also consider the diameter of the mains wires pretty small. Both probably wouldn't survive a certification in Europe.

My question now is: Are the Samsung microcontroller mentioned above and the "MK1841D3" somehow compatible? Has anyone tried mods on this crap?
Actually I initially wanted the "Youyue" to modify it with madworm's mods. 

To Madworm, what about just re-designing the whole Youyue-pcb? I'd replace mine with it for sure... Being just a beginner I can't do it myself.

Welcome to the forum, krondor.

Wow, that is quite different inside. Bummer. Hopefully, you'll still be able to mod it.

[Bryan]

Has anyone received the "newer" version that is advertised. All the descriptions seem to say 858D, but the picture is of a 2008D.

[wguibas]

You should just get this one, it is cheaper and doesn't require an adapter board if they are still shipping the real one that I got.

[Bryan]

Yes, but wondering if the *newer version*, has any improvements that negates updating the board and the hacks.

[Shock]

Third time in a row this sort of question has been asked. The WEP 2008D is not only a different model to the Youyue and Yihua 858D it's another brand entirely, all the brands and models have variations.

I get where you're going but even if the WEP 2008D shared some features, it's more about cheaply modifying your own micros firmware to add any feature you like.

So buy whatever you think looks good. Or the two models mentioned in this thread if you want to mod it straight away with less work. Or trace out the schematic and get out the datasheet for the Atmega and do a little "reverse engineering" and reuse the code.

Hi Wayne,
You have a PM.
Kovo said a few posts before that MK1841D3 is a clone of the Samsung micro, so I'm interested in buying your PCB :-)
Thanks to you and madworm for this very good job!

[wguibas]

I'm gonna have my hands on a unit with the MK1841D3 chip next week and I can see if the pinout is the same.  If it is I'll test the board and see how it controls.  I'll let you know what I find out then.

[Gixy]

Splendid! I'm looking forward to reading from you.

Nice video, I have the same unit originally.  Are you gonna try Madworms firmware?

[Shock]

No it's not mine I have the Yihua remember. Just putting it there so people know what it is.

[wguibas]

Got my hands on the Kaleep 858D+ with the MK1841D3 chip today,  looks like the adapter board has to be completely remade.  I sent out a new design today and should have them in about a week, then I can test and tweak.

Kovo said a few posts before that MK1841D3 is a clone of the Samsung micro, so I'm interested in buying your PCB :-)
Thanks to you and madworm for this very good job!

It might be a clone, but the pin layout on the board is completely different other than power and ground, so the blue samsung adapter board won't work.  This green board should do the trick, I might have to tweak the resistors and or code for the temperature feedback to be accurate like I did on the samsung board. 

[Gixy]

Full respect Wayne. And thanks!
