I got the J Tech Photonics laser upgrade for the Shapeoko. Started installing it today, hope to do some test runs this weekend.

Please be careful with that. When I started looking at laser attachments for the Shapeoko I decided the only laser I'd ever let myself near was one in a fully rated enclosure with idiot (me) proof controls. I'd suggest making a pre-burn checklist that you rigorously follow.

Agreed, coming from a lot of work-related laser work, there's a personal arm/de-arm sequence and there will be an enclosure before anyone else is even in the garage with me. I trust myself, but no one else.

Also need an enclosure for fumes anyways.

The thing I have learned working with a lasers is you need to treat it like a weapon: is it loaded/plugged in, is it safed/armed, is it pointed at the thing I am going to shoot and not at the things I do not want to shoot, am I wearing the safety gear, is everyone else safe or with gear on, do I know what I am doing?

Only then, do you press the button.

Shitty day out here, trying to motivate myself to head out to the garage and put my words into actions.

Truth, it is not.
However, it is raining and real cold. The weather does not agree with the great news.

Yeah I got wet driving down through Paso Robles this morning and the wind off the ocean has some bite in Carp this evening. I did wave when passing the exit for 135!

It's been a nasty weekend, weather-wise. Perfect for staying in and doing stupid things with lasers.

I needed an image to test out dithering and came up with this:

I've never seen one without coat hangers.

BTW, I pick the grey swatch on the left.

It was the winner.

Not sure where to put this, so I'll put it here: Does anyone have any single ended output transformers laying around that they would be willing to lend me for some testing? Specs don't matter much. Primary can be anything from 3K5 to 15K, any secondary appropriate for speakers (4 to 16) is fine. I'll clip lead them in, test them for a bit, and then send them back.

Sure. You want a pair? Or one?

Preferably a pair. I'm more of a listener than measurer. :)

Very cool. I assume this is for your RAAL amp experiment?

Different experiment, actually. Raal will be differential.

Sorry, don't have my nerd to English dictionary with me ATM. I'LL just take you at your word that it's for something else.
