after seeing the Laser Etched Powerbook project i got to thinking - i don't use a mac, and isn't there something a bit more temporal i could do? we were breaking out the saturday night munchies and i had an idea...

Step 1: unwrap chocolate bar

buy a quality chocolate bar, and unwrap it. do not eat yet!
<p>this is asesome!!!</p>
Wow. I wish I had a laser cutter. How many tries did it take to get that bar?
first try, but it was close - i found it in the 'baking' isle and picked it up, but then while transferring to my shopping cart i was distracted by a cutie looking at the brown sugar and almost dropped it!
Where do all your crazy kooks get your laser cutters? I suppose this one is owned by squid labs? I've tried and tried to convince my main squeeze that we need one, but then he hasn't gotten me a sandblaster either. Suppose I better work on getting a couch first. Really, though. Is there an artist's coop or something in the bay area that has one open for use?
any local hackerspaces?
not that i know of, but possibly Techshop in palo alto has one.
Just the other day at work we were talking about "branding" images into steaks (raw meat, pre-cooking). A coworker of mine did it a few years back. Pretty similar in concept.
oh yeah? just yesterday we were talking about "branding" images onto people (live, with skin). My coworker gave it a try.
Did it hurt?
for sure!
Funny you should say that...<br/><br/><a rel="nofollow" href="http://modblog.bmezine.com/2007/12/26/fingernail-laser-etching/">I found this</a><br/>
Where does the extra little chocolate flakes go? I don't want to waste any yummy chocolate. :(
I think you could cut through it if you put it in freezer for a couple of hours before doing it. Then simply put a piece of acrylic or wood under it.
This method was already patented in Japan on o7 Mar 2006 and the USA patent was also applied based on PCT/JP2007/054763. So, commercial operation with this technology is prohibited. If necessary, reply me. It is available to transfer or lend the right in the USA.
I found that you can also laser engrave polished stone, or even flat cut pieces of stone.
I have an Epilog. I plan to try cookies. I suspect that ones with a plain top like Vanilla wafers would work better than say chocolate chips.
You could turn a chocolate bar into a greeting that with this idea!
im a big time chocolate lover wooooo, thanks<sup></sup><br/>
what type of Epilog laser cutter do you have? How much was it?
OOOOOHHHHHH! I think I have a small CO2 Laser that is very underpowered at the moment. Im going to try and power it up a little and focus the beam better. Does anyone know if those CO2 lasers have a maximum voltage or amperage rating?
Just realized that it is a Neon - Helium (or something like that). Can one of these lasers cut, melt, do any sort of damage to something?
I thought of this immediately after I saw the laser etching contest but wow it's been done already and it was posted more than a year ago, sweetness!
They own the lazer cutter ;-) For cutting through the chocolate, why not try doing it a few times?
i tried it, it doesn't work because the chocolate is too melty, it just flows back into the groove. you can get through it eventually but it's a big mess.
I spelt laser with a "z". Wheres my coffee?
Wait-- where is this laser cutter? Do they have one at the TAP Plastics down on South Van Ness?
This is great! I'm going to get a laser cutter.
I haven't tested any of this, but I think the chocolate might hold up better during either process if you put it in the freezer first.
didnt they brand the image of Jesus on a mcmuffin or something?
That's cool, we did that too when we got our laser 9 years ago (Universal 25w). It was fun to try all the things it could do. The joke here was: "Can you do tattoos? Yeah, as soon as I figure out a clamp that will keep people from moving!"
