From the menu I put him to sleep time (10 minutes). And 'possible to insert in a soft "beep" warning that starts the sleep period?
Thanks again[/quote]

Firmware needs to be updated for this. And I don't know when I will have the time to update it.[/quote]

Is the firmware somewhat hardware independent? Using the same MCU family, but in a similar way to Mikrocontroller.net's transistortester?

Can it be made Affero GPL v3 or greater then? It would be nice if it's used by more projects, so there could be a bigger community behind it :D

Thanks a lot for your project!

[quote author="chemary"]Hi,
I have uploaded the last code to bitbucket https://bitbucket.org/chemary/upartninja.x

I have recently revised the code because my Part Ninja seems to get stuck under some circumstance like testing P-Channel Mosfets but I have not found yet the error.[/quote]

Thanks a lot!

Why did you delete the history?

Project development, ideas, and suggestions / Re: DP Part Ninja
Hello

I mirrored it for historical purposes.

The developer that did some improvements used Mercurial. He maintained the .hg directory in the first tarball, but not on the second one. Another issue is that he didn't use the original directory structure and I have no clue how to merge the changes.

https://github.com/timofonic/Part-Ninja/

Unfortunately, I have no clue about SCMs/VCS, even less DVCS

Can anyone submit a proper pull request? Even better if preserving history, so I encourage the original author to do it.

Kind regards.

[quote author="sparkybg"][quote author="Sjaak"]BTW for desoldering PTH I use my own t12 controller with a K tip  and soldersucker.

I also used this for desoldering. But, believe me, get a decent desoldering gun - the differene is HUGE.

Sorry for the multiple messaging and parallel conversations...

I just found these desoldering stations have issues wih the power supply, firmware and it seems the pump system.

It seems that someone developed a firmware for it, the device uses some clone of the 8051 that is programmable. Did you use it?

[quote author="Sjaak"]Don't think you need a stencil..[/quote]


Okay. Now I'll need a way to solder SMD chips without destroying them. I'm still an awful solder :(

What does it mean Protopack +-10.

The price is for one PCB plus the stencil I can opt to not get it, right? I'm confused as hell, sorry for being so dumb...

[quote author="BadAd84"]Hes ordering 10x 10 PCBs. so thats 100 pcb price.[/quote]


Sorry for me being a dumb, I did think that meaned the size.

I used the elecrow service.

Is this okay?

It seems interesting! Desoldering is extremely painful for me :(

I tried to make an order, but the costs are too expensive...

@Postby Sjaak

I know, but it can take too many weeks until it arrives. I need a soldering station, but I'm not convinced at all by the cheap chinese ones I tried.

I might get the cheapest one and a heat gun, but I'm thinking about replacing the PCB and putting UniSolder on it.

@BadAd84

When did you made the order? I lack a proper soldering tool and I already burned my hands with my pen soldering iron.

Would you solder me the most difficult components? I'll try if someone helps me with them, but I'm not sure about that.

Project logs / Re: Really universal soldering controller
Are there anyone in Europe with PCBs? I'll try to finish recreating the project with KiCad, but I'm having some issues and really need a soldering station. The low end ones aren't so good for me, I'm not totally convinced by Hakko and Ersa ones.

I wonder about adding desoldering to the device. There are relatively cheapo desoldering station, so I can cannibalize the components. I wonder if the soldering station would need to be aware of the desoldering function in order to improve the process or just a switch to desoldering pump would be enough.

[quote author="sparkybg"][quote author="SZ64"]
Is it true that the voltage VCC is 3.3V? According to Formula Vout = 1.21 * (1 + R2 / R1) voltage is correct 5.00V. I think it's a mistake at R4, instead 1K5 should be 2K7 and then the voltage is exactly 3.316V.[/quote]

Yes, it is 3.3V, and it is my mistake. When I use LM2675, I usualy take non-adjustable part and in the same time I am providing the option on the PCB to use adjustable part.

Because adding 2.7k resistor will add extra component value to the BOM, I will replace the regulator with LM2675M-3.3 and the upper resistor with 0ohm. If you take a closer look at the PCB, the upper resistor footprint is a little different - the pads are closer to each other so a solder jumper can be made easily.

Thanks for mentioning this.

I will soon provide general rules for connection and identification of any new instrument in the first post.

Generaly, for separate sensor connection, the sensor-, heater- and outer shell are connected to Vout1-, GND and SENSEB, heater + to Vout1+ and sensor+ to SENSEA. Any single heater instrument needs 2 resistors for identification and any 2 heater instrument needs only one resistor for identification, connected between ID and Vout1-.

On Vout1- you can use only even IDs from the "ResID.xls" file in the software.rar. On Vout2- you can use any resistor from the table. The odd IDs on Vout1- are reserved for built in profiles in the firmware. Somewhere in the future, when I got enough time, I will finish the PC software and the firmware in order to create custom profiles easily, adjust PID parameters in real time, and store these profiles in the EEPROM. But I cannot tell when I will be able to do this. For now, you will have to add  your profiles to the firmware and recompile it every time it changes. It is not so hard, but is pretty annoying - I know.[/quote]

Oh, I didn't know that! Are you planning to update your files and such? I'm sure you're pretty busy IRL...

[quote author="sparkybg"]You can make any clones, you can use my schematics and firmware, end everything else, as soon as you are not making any profit out of it.[/quote]

Of course not. It's my personal DIY project. Thanks a lot!

[quote author="sparkybg"]Please open your own thread for your clone. This thread is for my implementation.[/quote]

Sorry Sparky, I didn't want to annoy you. I just wanted to explain my derivate project and intentions.

I just want your explicit consent to make this "clone" because I respect a lot to you, your design and efforts. I don't consider this pseudoproject to be a clone, but a fork.

If I'm able to reach my goals and you authorize me, I'll sync all your  changes and use the same firmware if you agree. I hope to learn enough to contribute in the future if possible.

I just would like to have clear all terms about this, such as licenses and such. I'll agree whatever decision you make about it, you deserve it. But you deserve to be mentioned, if course.

I consider your project something very interesting to use and understand it. I think it's an extremely flexible soldering station.

I'm not as skilled as you, but I would like improve my skills at EDA software with my fork and learn by solving issues. I want to go the DIY way to make a custom solution to my personal needs, even if that means lots of efforts.

I'm not going to contaminate this thread again about my "toy" based on your great project. I'll write a new post about it when I have some really relevant results and make a short reference if you agree too.

I can delete or edit the already written posts with irrelevant information directly related to your project. I would prefer it to reduce noise, but I like to know if you agree on it

Thanks a lot for everything!

Kind regards.

[quote author="sparkybg"]Circuiteromalaguito, for now I am not sharing more than I've already shared. You have the schematics and you can rewrite them in your CAD in a few days. And this is nothing compared to thinking it out 5 times (5.2 times, exactly :) ), and designing and debugging the PCB several times. This is what I share - a working project with schematics PCBs and software. If someone wants to use it to develop his own version/clone, I will gladly provide any help I can, but that someone must be ready to do some work himself.[/quote]


It's okay and fair.

I'll work hard to make the schematic in KiCad first and be sure it's correct. I'll provide the results here.

Then I'll try to do the PCB layout after planning what to put in the chosen suitcase and future upgradability. I'll provide my versions here too.

I would love advices and suggestions from others, of course.

Next post will be about my schematic.

Thanks a lot!

PS: Would it be derivative work?

Project logs /
Hello.

Thanks a lot for your project!

Your project is what I really wanted, a very flexible soldering controller with lots of possibilities. I really like to build things myself and analyze to understand them, but I need to earn the skills and the path is sometimes too difficult. Fortunately, things are getting better.

Projects like yours sincerely provide me a lot of motivation and inspiration to go forward. I appreciate a lot your contribution, people like you make me remember there's others that deserve to be appreciated.

- Wouldn't you mind sharing the Altium files to convert them to KiCad and modify them?
* Of course, all copyright and license will be the same.
** I understand your copyright assignment and your non-commercial license. You really deserve it.

* I would like to design at least my own PCB to put it in some kind of portable toolbox-lab.

* If you don't agree: Things will be harder, but not impossible.
** Anyway, I'll politely respect your decision if you disagree about me designing my own PCB.
** I don't want to do something that might upset or hurt you in some way, so I ask you for permission.

* If you agree about replicating your elaborated design in KiCad but not providing the Altium files for whatever reason:
** I'll keep moving forward and do it even if it takes me a lot of time.
**  I need to fit a bunch of stuff on the same box, so the board needs to be redesigned and adapted to a new approach.

* If you provide it:
* t will make the process a lot easier by using Altium2KiCad.
** Despite I might need to fix possible converting issues and modify the PCB to my needs, this will make things a lot easier.
** Maybe I'll need to create new components for KiCad, I'll see it as a learning experience.

- About Altium versus KiCad:

* I understand Altium is a lot more powerful than KiCad these days, but not economically affordable for most of us.
** I prefer to use and promote KiCad because of this and not having vendor lock-in.
** I understand you might consider switching to KiCad a very backwards and unpleasant experience, you must be very used to this powerful but expensive tool. ** This way, more people could experiment on your design and learn from it.
** Anyway, you can still keep using your great tool. I can sync your PCB changes to the KiCad "port" if you need it at all, but it seems the hardware already seems quite robust.

- Have you considered putting it in GitHub too? People could make their own versions easier and provide contributions
* Version control might be useful to spot bugs too, maybe you use it internally.
* On the other hand, the firmware has infinite possibilities, specially on supporting more devices. I would love to learn about that in the future and contribute to it.

- My reasons:
* I want to manufacture this complex board as a personal challenge with the help of my new vocational school and try to fit many stuff in a small space.
* I would love to have a portable lab-toolbox in a strong and comfortable suitcase to:
** Not have back pains.
** Avoid theft.
** Never miss stuff I need to do and the required stuff,  enforce organization.
** Do most of my stuff everywhere, so I can travel to see my girlfriend or while work breaks if I get a job.

- Most of this project will only be possible if I get a job.

* Failed students don't deserve scholarships, despite the former vocational school was very negligent and hostile to me.
** I'll work hard to earn some bucks and make my "pseudoprojects" based on others.
* I'm not going to be defeated by the former bastards that made my life worse, it's time to learn from it and progress up better than ever!


- I hope to do a great contribution like yours some day in the future, after I learn enough for it.
* I'm a copyleft hippie but and still low productive one, I confess it.

- My new vocational school is a lot better than my previous one:
* They seen very open to personal initiatives, proposals and develop own projects.
* I have been very lucky to this change, because they seem very positive people that tries to understand and motivate us all time.
* They are very flexible about choosing our tools, they have dual boot Windows/Linux in their computers.
* Their teaching way is a lot more near to the Active Learning approach.
** Unfortunately, our government and specially the one of my province are bureaucratic and unrealistic with a retarded approach and insane methods.
** Baskes are dramatically a lot better at vocational schools.

- Despite I want to follow the DIY way as a personal and learning challenge, I would like to contribute when I get some money.
* Do you accept donations?
* Do you have a wish list? If so, please publish it somewhere.

[quote author="SZ64"][quote author="sparkybg"]- updated the firmware with correct instrument name display
- added gerber files for combined PCB (front+back+OLED). It may be cheaper to fabricate this way.[/quote]

thx sparkybg !

p.s.: I am still waiting for Hakko 907 iron-connection and if possible please to Zhongdi desoldering gun ZD-552 ;-))[/quote]

Patches and donations are welcomed ;)


Thanks a lot!!!!!!!

Kind regards!
