A fancy LED driver
60x60 Light panel on

Found a 60x60 LED panel for 20dkk in the thrift store last week. Found an LED driver in the trash a couple days later. Just had to adjust the output power and change the power connector. Who knows, dali control might be broken, but I’m not living in an office. Think it’s gonna be my new work desk light.

From writing a first post

Okay this thing has been in the works for a bit… And on the backburner for much longer. The general idea is just to have some place to put things that I’d want to share, or might be useful for others.

Read More

Immediately obvious TODOs from attempting a first post:

  • Add the read morefunctionality as a shortcode.
  • Fix up image rendering.
    • Do auto-processing of images so I can paste without care. Also a shortcode thing..
    • Specifically, clear EXIF data and such…
    • Click-to-maximize.. With higher resolution versions?
    • Add gallery view style rendering…

Also I’m not used to spur-of-the-moment writing. Interesting exercise. Also, doing proper automations for creating posts etc was a good idea.

Okay gallery shortcode implemented.

Read More

Readmore shortcode as well… Currently using the details html tag to have a js-free solution. Seems to work fine, as long as the button doesn’t need to move to the bottom. Wondering if that could be solved with css as well…

Next up… Better image rendering? The building the plane as it takes off approach is pretty neat tbh.

Okay, image rendering is in a workable state now. I also fixed up the front page to show sections properly (and added a right hand sidebar):

Some obvious next steps:

  • Don’t convert png’s if smaller output.
  • Automatic read-more solution to shorten replied-to posts?
  • Return to main page button if header disabled.
  • Figure out tags and comments.
  • RSS feeds for everything.
  • Video shortcode.

Rollei Bullet HD actioncam with dead batteries

Batteries are soldered in parallel on the board.
Two puffed up lipo cells.

I found a Rollei action camera in the trash. Seems fully functional except it won’t take a charge. The shell clicks open after removing the four visible screws at each side of the camera. The camera has two lipo flat-packs wired in parallel and soldered to the board. Only one of the cells has a protection circuit, the other’s wired in behind it. Both cells have swollen significantly.

Battery specs:

Two new lipo batteries next to the opened camera.
The lipo batteries attached to the camera cell and neatly soldered onto the board.

Bought a couple of the AKY0477 batteries from TME and got them installed. There’s a bit of free space around the camera lens where extra cable can be tucked in.

Batteries replaced aaand.. it works perfectly.

The camera fully charged and ready to record.

Now what in the world can I use a little action cam for…? I also found the cage for it with a broken hinge. Maybe worth fixing.
