BCM vs. dumb software PWM
| |
|
Both are interrupt driven. The left side uses BCM (Binary Code Modulation), the right side uses 'dumb' software PWM.
Identical hardware!
A lot of blooooood...

Cutting myself... I'm sort of used to that. But impaling digits on a knife is a whole new experience.
Not a single insect bite this summer (cold one), and now this!
No more dishwashing for now...

My first MOSFET ever
| |
|
It is a BSS138, a small (SOT23) n-channel logic-level MOSFET.
It works ;-)
If it didn't work you wouldn't see anything, as the MOSFET controls the LED used to illuminate itself.
The buttons vanish nicely!

Seems like the laser focus is not set to the middle of the work piece. The Rayleigh-Length of the focus is pretty large (shallow focusing). Otherwise the curvature of the edges would be intolerably big.

A fortuitous accident
| |
|
I didn't plan this connector to go there. It was meant for a different one, but I forgot that the MDF is 5mm thick. This connector accidentally fit, so I used it.
Almost done!
