I would look into the type of wood you're using as well as the focus of your laser. And the lens should be cleaned regularly. And the alignment should be checked for deviation. If the wood is cheap, it has lots of glue in the center bit. If the laser bed hasn't been adjusted for the height of your material, it'll just char the wood. If there is lens dust, you'll lose energy heating up that dust instead of the wood. I had LOTS of trouble using a 40w or lower laser to cut wood thicker than 3mm. Glow forges are expensive and underperform in my experience. My Chinese laser from ebay is 80w and has a 50cm by 70cm cut bed. Cost including freight shipping was $1,800 and it arrived in 2 days. Really cool for making big stuff.

Hello! I use a 60w laser from china. I use speed 6mm/s and 60% power. I believe I use a lower range frequency so avoid heavy edge burning. An air blower helps too!

It is so strange that you've done that too!! We built an x-ray tube out of an old brass base vacuum tube and a high voltage power source. We used a image intensifier screen and nightvision to see the x-ray results in real time on the image intensifier. It was like having super hero vision. Well worth being irradiated.

thanks!

Thanks! I plan to follow up with a film developing instructable soon!

Cut files and 3D print files to follow! I'm not home yet! ;)

Is it possible to use a push button instead of a microphone? So a certain number of pulses would open the lock?

This is really great!

Installing this system tomorrow. Thanks for posting this.

Thanks for the heads up! Yes, I know. ? believe me, I'm a props fanatic. And, this seems like a great opportunity to learn about screen printing cloth covered book binding! stay tuned.

Thanks! :)

I purchased it on eBay. it's a solid-state device. just call the Chaser light box or module. back in the old days they used to be mechanical. basically a motor with a cam that would open and closed switches in sequence.

You're amazing.

The backboard has 2 layers. The black stripes are 1/4" laser cut and provide some delicious depthy shadows.

Thank you :] I know you're opposed to hot wire cutters but maybe you'd like my design. I'll put up an instructable sometime. I NEED stencils though so it may just be me! haha thanks again!

1948 Supreme Court ruled in Tesla's favor. These are Tesla's inventions, not Marconi.

There's an instructable that uses an arduino and it translates morse code from a push button on to the computer screen. Could this print the morse code translations you think? Thanks!

I'm thinking two sets with transceivers attached to actuate the 'switch' used. Steampunk spy walkie talkies. Without the talkie bit. Dottie Dashies?

I'd like to make this print to a portable thermal printer. Any notion on where I might start? :)

Hi there! great instructable! I'm trying to figure out how to pulse an LED at 80 times per second. Could you point me in the right direction?

Hi! I am trying to figure out how I can pulse an LED at 80 times per second (4.8khz). Could you point me in the right direction?

I'm trying to find out where to start if I want to blink an LED panel at 100 times per second. Could you point me in the right direction? :)

Is it possible to blink the light 80-100 times per second with this circuit?
