Sign scripts version 4

When I released the video with the scripts for making the signs it was pointed out that because I had moved from processing in 3D to 2D I could replace the minkowski command with the offset command.

It shaves some lines of code off the scripts, but strangely it doesn't shave any render time...

Poundland crackle globe customising

It's a while since I've made a video about customising solar garden lights.

This one from Poundland is actually very good and has lots of options for improvi...

Not clickbait. People are actually doing this!

A video to show how to charge salvaged lithium cells properly, as opposed to the apparent trend of stripping a USB lead and using that to grossly overcharge them!

That you can repair magnetrons. Not that I recommend doing it unless you really know the hazards of working with instant-death microwave circuitry.

I popped my porridge (oatmeal) into the microwave, pressed start and was rewarded with a much louder hum than normal before t...

Inside the island's bakery that just closed

Due to the spiralling costs of fuel and materials, the owners of the Isle of Man's main bakery decided to cut their losses and close it.

Inside a classic cheap jump starter

This is the unit I showed in one of the live streams. I got it to check out internally for consideration as a compact high current power supply for costume lighting where it will need to supply 12V at fairly high current for a short period of time.

A genuinely surprising bit of circuitry

I don't think it's the circuitry that is the special thing about this. It's the use of what may be standard zinc-air cells as used in hearing aids, but the cells are used in a very strange way.

Behold Version 3 of the sign script

Well this turned out well. I've modified the script to give consistent wall thickness regardless of angle, give gently rounded exterior corners to sharp letters and by using 2D minkowski processing and then extruding the resultant shape upwards as required, I've managed to reduce the render...

Rewriting the sign making scripts for turbo speed

Tonight's task is rewriting the openscad sign maker scripts.

If everything goes to plan the new script will slightly round sharp corners, provide more consistent wall thickness on angled surfaces and best of all, will potentially reduce rendering time to near instantaneous, even for large c...

(Spoiler) Ever wanted your name in lights?

Spoiler for an upcoming video with scripts.

There are two scripts. The first one makes a sign box of any height and depth you can print, and the second one makes a matching face for it.

The script should work with any font that openscad can use, and a variable called "fit" means...
