It’s been a while since I got the soldering pen to work.
Now I’m back with more good news. I’ve printed the first casing for the electronics!
Yes it might not be much but it’s there! Looking more pen-ish than ever.
What do you think?
I haven’t added buttons yet – they will go in the two holes farthest from the tip.
The hole closes to the tip is for a small light-pipe so the LED can shine through the casing.
I was thinking some white PLA in 3mm would suffice.
I’m still working on buttons.
I’m not convinced that my initial idea will work so adding the buttons as small pieces of plastic might be the solution.
Here the pen is heating. The red LED is really bright!!
Next step is to convert all parts to 0603 so I maybe can have it produced locally.
Also I will be extending the PCB beyond the 50mm limit I was currently working on, making room for a barrel jack connector for the 12V.
I should make a gif.. the green is pulsing, indicating that working temperature has been reached.
The biggest problem is now that the mini-jack connector is only rated for 1A and the tip is requiring 2A..
The connector gets warm.. I don’t think I will have any luck finding a high-current low-profil mini-jack connector..
