PAGE 1 of 6 - Homemade Soldering Station
Hello, i've made the Homemade Soldering Station with atmega from Hercules Trapierakis

Could you please email me the source code for that station, or at least tell me where to look for it?
Thanks in adveance,

what is the recovery time of the temperature of your iron 15watt?
what's an iron suitable for this project? 15, 25 or 40 watts?
Thanks a lot :D

yes its less, but there is no problem, the only thing that you may face up is that if you place the protective of the cable too close to the soldering iron it may melt, there is no other problem, it work perfect

Sorry but 400°C max operating temperature, and 200°C max temperature for isolation of thermocouple K cable, they are less for this solder station that reach 500°C?

the same with an AVR
and with a PIC

could you provide the initial link of the project??or the code and shematics?!very interesting project!!WEll DONE!!

try to reverse P and I factor
At 8 May 2012, 13:38:56 user Pantelis wrote: [reply @ Pantelis]
increasing the i factor,at the selected p, the osculation is very big

its working much better now
but i can not keep the temperature stable, look at here ,its /- 8 degrees,is it normal?Shouldn't be stable .
From this point start the problem, because if i set it to 250 C for example ,it is mouving around 245-255.
I have to say something that maybe is wrong. From the pcb until the 3.5 mm famale jack (its about 10cm) , i am using a normal cable and not thermocouple cable, because thermocouple is not long enough. As George said at his tutorial ,i think it is wrong, isn't it?

How its working now?
Have you used pin headers for 220??????
At 25 April 2012, 5:24:16 user Pantelis wrote: [reply @ Pantelis]
my wrong was that when i set fuse and i push ok ,but i should push write at ponyprog , now its working at 8Mhz.

yes i know the values
there are on my post under the hex files
also i have posted here in my older posts
i dont use ponyprog
search on youtube how to set the fuses
its in normay speed

sorry, your video is in normal play?? i thought it was in forward mode!!!!!
so, i adjust the fuses like that
the only value i change was
internal rc osc 8 Mhz ... 64 ms, the fuses goes to Low: E4 high: D9
and i place the configuration bits as i saw these at the photo, but i couldn't change the SPIEN ,it was grey and i couldn't tick or untick this
What is wrong?
At 23 April 2012, 10:03:25 user herctrap wrote: [reply @ herctrap]
No the fuses are still wrong
check my video
see how fast the "by herctrap" is
and see for how many sec the PID factors are apear
and how faster is the responce on the bargraph

i did all my best!
i already place the fuses
is there anything wrong here?

this command is for avrdude
i am not sure if it is working on the ponyprog
At 23 April 2012, 0:48:55 user pantelis wrote: [reply @ pantelis]
yes it real ,i don't have touch fuses,i search and i found this
Here i change only <<AVR part name>>: atmega8 and at <<current settings>> i change E1 to E4 and now i have this
-U lfuse:w:0xe4:m -U hfuse:w:0xd9:m
Now i have to place this string at conmmand line to the ponyprog, but i can't find command line there.

you have to fix the fuses for the avr also to:
Lfuse = E4h
Hfuse = D9h
you are running 8 times slower
so you are not updating output fast enough

@Pantelis This is typical overshot from bad PID values. Use smaller P and larger I, and no D at all. The, start playing with the I time. This will reduce the reaction and probably the overshot.

So, i am trying all day to achieve the set temperature but i canot achieve to make it work like yours hercules. I have a variation about /- 10 degrees.i am trying to achieve a set temperature at 100 degrees and it goes about from 93 to 110. i have outcome to the conclusion that my soldering iron is 60 watts and when i am trying to reach the set temperature it rise about 10-15 degrees in every 8 seconds whereas yours because its only 15watts, it rises just only 2-4 degrees every 8 seconds.
I am saying that because i try it with a lamp 40W and it works perfect just only /- 3 degrees variation , afterwards i try it with a lamp 60 W and i saw it was even harder to stabilize at the set temperature, i had a variation about /- 3-6 degrees .The best values that work for me was p=50 i=2 d=1.
That's my conclusion ,maybe its wrong ,if you have to say something to try, i will do.

ijust saw your video
i think that you dont have set the fuses
Lfuse = E4h
Hfuse = D9h
it seems that is running on 1Mhz and not on 8Mhz
At 22 April 2012, 13:51:02 user herctrap wrote: [reply @ herctrap]
try these values
P = 50
I = 2
D = 1
i will test them again

@Pantelis to set the pid you will need to see how the temperature behaves and then play with them. it is not that hard, but you will need first to gain some experience
At 22 April 2012, 1:41:21 user Pantelis wrote: [reply @ Pantelis]
yes its log,but i think its doesn't need a very specific set of temperature but if i found a linear i 'll place it. I have to read about pid again
the 4 corners are aluminum, the 4 profiles are wood ,these was from a ground stand about 1 meter, i found it from a shop that were hanged up some bones ,its very nice and easy to work with it. I don't know if these are sold somewhere.
So, my problem is the adjustment of the pid values ?
At 22 April 2012, 1:10:08 user Giorgos Lazaridis wrote: [reply @ Giorgos Lazaridis]
hmmmm, i think that the potentiometer you use is logarithmic. A linear potentiometer would be better. The PID values have nothing to do with the temperature set-up. The PID values affect the output only. Check this out:
This will be a good start for learning PID.
Some photos from the complete project????? Can you upload for us to see? And where did you find these plastic (or aluminum) profiles that you use in the 4 corners of your box? I like them, i think i can use them as well...
HOT in heaven!
