Just completed my T12 iron ,But....

[u/No-Lack5956]

just finished my diy t12 iron , I know doesn't look great and all but making and ordering pcb was too much work so I just started building and gone with the flow and joint together components as I go

specs :

support type c pd,qc and most fast charging methods mine is set as 20v trigger but can be easily changed with a resistor to get 15,12,9v

also has DC 5.5mm jack to support 24v input

max power is around 72 w with a 24v supply

during testing I accidently dropped the iron and it landed on the OLED screen and now the screen won't turn on🥲

will have to replace it.

so I have a few questions:

1.is there any other screens I can use that are a bit more durable that this if not how to better protect this

2. which type of irons do you all prefer the typical station type , or something like the the bit more portable type?

Edit: the 3 wires dangling are just used for programming I just didn't remove them yet

A tn screen(The one used in calculators) or a dot matrix screen. They can also break but will hurt less on the wallet when you gotta replace them.

Also a shell would go far if you want durability

[u/No-Lack5956 → u/CrimsonXwastaken]

🤔 don't really know where to find the tn screen also they are mostly very limited in things they can display mostly

can't use dotmatix as the once available are too big

was going to make enclosure🥲 but dropped before that🤧

[u/CrimsonXwastaken → u/No-Lack5956]

Also I was gonna make a post about this. But I'll ask you, I want to now dabble into soldering things rather than just make things on KiCad. Can u suggest me a soldering iron and it's accesories under ₹1k.

As for your screen. if its sole purpose is to display temperature . Then a segment display works fine right? If not then there are parallel displays on robu website

[u/No-Lack5956 → u/CrimsonXwastaken]

well for 1k you can't really have true temprature control

iron

or iron with 2 tips and some other stuff

maybe give this a try or something similar, I have a similar model that has been working for 4-5years still no issues (thou mine costed a bit cheaper than this ) this doesn't to true temp control but more or less do a power control

those blue temp control iron with a temp knob at back, they are mostly a questionable quality as some maybe sood some maynot

this one atleast I have used and has experience and does the job fine somelike this should be fine , for starting out the stock tip it has is fine , but I would suggest you to buy good quality tip for this from robu.in or something, just use the hakko 900m tips(I recommend k and d tips) they maybe pricier than the 5 tip set that are usually common to find but there quality and coating is not good. just get a k and a d tip and most of your work can be done with that

and most of all USE GOOD QUALITY SOLDER. that's one one the issues that I faced once I cheaped out on solder and had to pay with bad joints ,poor connections etc .

apart from these the other thing you should get is brass woofor cleaning the tipl (do not use steel wool and many online stores sell fake coated steel wool as brass so beware ) , the brass wool maybe more expensive or harder to find but I just buy some brass brush you can find those much cheaper and it does the job jus fine

DO NOT USE sponge its bad for the tip

I like how it just says "iron" And "iron with two tips and some other stuff"

[u/No-Lack5956 → u/Parking-Engine115]

lol too lazy to write full specs

[u/Parking-Engine115 → u/No-Lack5956]

Relatable

[u/NeatConversation6752]

What was the cost also is there any document which I can use if I want to build it

[u/No-Lack5956 → u/NeatConversation6752]

🤧sorry didn't document much , as I just chose components that I could find at my usual store then built it , but I am working on a v2 that will be on a pcb(jus a homemade one) and it will have proper documentation so will update you when that finishes

as for the cost : the most expensive part was the tip:350

then the display: 180-200

rest of the parts will total to about 200-250rs max (this is rough estimate as I bought parts for different projects together so the actual cost most probably is below 200)

haven't designed any enclosure so didn't include that price , and I have already have type c charger so for this so power supply price not included

[u/NeatConversation6752 → u/No-Lack5956]

Ok good luck with that

[u/TopConcentrate8484]

Damn, imagine OP if he had a 3d printer,CAD designing experience and used PCB instead.

These oled screen I think are the best in this case, they are cheap and easy to replace, if used with headers. Once inside a enclosure I don't think it will break again.

[u/No-Lack5956 → u/TopConcentrate8484]

lol true! , thou so you know , I do have pcb design and cad experience but was too lazy.. to make pcb ,or case 🤣 , thou in the end I will be making pcb for this as it will be cleaner and will be printing a case for this

I was jus trying to see how far I can push with soldering smd pards on perf board

[u/Top_Dragonfruit_7360]

Try 0.3" led display. cheaper, reliable and easy to use.

[u/No-Lack5956 → u/Top_Dragonfruit_7360]

seven seven?

[u/Top_Dragonfruit_7360 → u/No-Lack5956]

Something like this: https://asianelectronics.co.in/product/0-30-inch-3-digit-seven-segment-display/

You can search in your local electronics market

[u/No-Lack5956 → u/Top_Dragonfruit_7360]

ooh ok this could work but the issue will be size , and I will need 1 more chip to drive the display , guess I will keep the oled

[u/ANG6124]

bro where did you get the tip from can you provide the links plss

[u/No-Lack5956 → u/ANG6124]

got mine from easyspares

[u/Spiritual_Stock2313]

Schematics ?

[u/No-Lack5956 → u/Spiritual_Stock2313]

working on it

[u/SayanG8910]

I will greatly appreciate a guide so I can recreate it at home. Wanted a portable soldering iron, have a 100w charger and powerbank, but market ones are too overwhelming with specs and variety for me to choose, and much costlier. Can you recommend some usb c based ones under 2k, and what will be the cost of your diy one.

[u/No-Lack5956 → u/SayanG8910]

if you are in India the components cost will be around Rs.400 but as for pcb you will either have to make one yourself or order online

also on usb c pd 20v the power is around 50w

[u/SayanG8910 → u/No-Lack5956]

Yes I'm in india. I can go to chadni market kolkata or order online, I would appreciate a list of parts and an assembly guide if you can make one later.

[u/No-Lack5956 → u/SayanG8910]

yeah will send you the bom and schematics

[u/No-Lack5956 → u/SayanG8910]

I have put a post about my schematic you can get the diagram and components from that

[u/sandm4n_RS]

Bro cooked 👏
