Old Lumens Challenge 2019 - Hand Made Entry - ceruleanXLII

Just need to preface this with:

  • I’m very new here, this is my first post, please point out any embarrassing social blunders, indiscretions & formatting errors.
  • Trigger warning to grammar / spelling nazis: I’m dyslexic.

I’m wish to enter under the Hand Made category / build log

The plan is a lamp powered by a simple DIY boost converter driving 3x LED panels from a single AA cell. Totaly impractical, but fun.

Step1: learn how to embed pictures into posts

This is the LED panel I plan to use (not my picture) and a test for embedding an image… here goes

Step 2: Tidy desk, tidy mind. Make some room to work

(Ok, on further consideration I’m getting ahead of myself. Step 1.5: Have a beer.)

Step 3: lay out and test the COB panels.

Step 4: Wind the inductor for the boost circuit.

Now given that I have no idea what the magnetic permeability of the ferrite is and inductor design is black magic anyway (Read: I’m terrible at maths / physics) I’m just going to wing it and fine tune later.

Welcome ceruleanXLII ! Don’t worry about social blunders the only real blunder is being offensive but we like to think we are pretty friendly here.

…and good luck with your build :beer:

Thanks Pinkpanda3310!

Step 1: learn how to post images!

:+1:

Please enjoy your time here, ceruleanXLII!

Round 6 10 whatever image post:

12V 70W 7000LM LED Panel

Edit: success! Imgur really doesn’t want to make with the direct links!

Welcome! I’m excited to see your project come to life.

On the images, I just find the picture in my imgur album, then right click it and select “copy image link”. Then, I paste that into the post editor “insert image” box and I always use the “relative width ” option (usually around 30-50) to keep the size manageable.

RE: f0xx

You are on a computer, right?

My mobile phone refused to play nice. I had to use an alternate browser (duck duck go)

I like the way you think, setting out steps, telling us & working through them.

Good to know that you get that I’m doing this for good fun.
