Soldering Pen Demonstration! It’s here!

Hi everybody!

I’m done. The soldering pen project is done. Well, At least in the first form where I feel I can release it to the public. A small beta-test have already given me changes that I need to implement before going to the next level and really trying to sell the pen but have a look at the video! I even found a case to ship it in πŸ™‚

Now, I’ll let the video speak (that’s still me speaking though πŸ™‚




  1. Awesome! Quickly skipped a bit through the video as I am at work, I’ll view it again sometime this weekend.
    Just one thing I am missing, in particular on this Black Friday: a big red “Instabuy” button!

    • Haha πŸ˜€ Yeah I know that quite a few people want to buy it already.
      I have a few kinks to work out still – based on feedback from a frew betatesters:
      1. slightly longer cable – maybe teflon (If I can find this and it doesn’t cost an arm and a leg I’m all for it
      2. Adjust the location of the magnet to improve hibernation detection
      3. ramp-up on the PWM (will increase the heating time slightly but decrease the initial load on the PSU which is above 3A at the moment)
      4. Add run-away detection so if the temperature doesn’t change when heating the pen shuts down.
      5. maybe add voltage detection since I fried some tips while not getting it to work at 24V.. I got 4 dead tips now :/

  2. Well done. Congratulations πŸ™‚ I am looking forward for the order button πŸ™‚

    • Yeah, I know I’m a bit reluctant to start the sales just yet. I really want this to work well before letting it loose. There’s still some minor things to be done but it seems promising!

  3. Hi HP
    Great device, I use this Weller RT tips all the time but a bit complicated to change the temperature – long procedure and monitoring lights flashing – counting.. ..
    – basic settings – 250 C start temp +50 and -50 Deg C as a simple press of button maybe….
    But all right man – let me know when it will be out on market!

    • Thanks for the comment!
      The thing is – how often do you really need to change the temperature? I’m using an early prototype to assemble the finished versions. the prototype have 350 degrees hardcoded into the firmware and I haven’t had the need to change it yet.
      I do see your point though. Another person suggested that the pen should simply have 3 presets that you could toggle between.

      A completely other option would be a mode to change modes… or would that be too confusing πŸ˜‰

  4. Happy new year

    Is there any news?
