I really like our Lumen Lab CNC. It came with a nice aluminum deck. However I wanted to avoid messing it up by ill thought of CNC commands. So I make a laser cut-able 1/4" cover.

I created this many months ago and forgot to upload this. This is designed to be used Lady Ada's xbee mount. Here:
adafruit.com/index.php?main_page=product_info&products_id=126

This is my XY plotter that I created to test out our ARC code for our multi axis (up to 254 networked) stepper motor controller called TinyG. You can read more about TinyG here.
synthetos.com/wiki/index.php?title=Projects:TinyG

I do realize that it would not take much more to create a z axis and make this a CNC machine. This is the plan. However if anyone else wants to mess with it. Please go for it. Also, if anyone is in the Washington DC metro area and wants to mess with the machine let me know.

The metal parts are all made from the contraptor frame work. (http://www.contraptor.org) However, that being said you do not have to drill the holes in every part. Just drill them where you are going to need them.

All metal is aluminum with the exception of the Y axis "angle rails" these are made from home depot steel angle. Both steel and alum angle is 1" x 1" x 1/8". Possibly the coolest thing about this design is the fact that all the stuff that needs to be accurate is cut with the laser. Another cool feature is your size limitation of this is really only limited by the length of lead screws / angle rail length you can get. This design should be easy to support 6 - 8 ft tables with no real "changes" needed. (I think..)

The bearings used are 805 regular skate bearings. (5mm centers.. or 5/16") All hardware (with the exception of the 5/16" bolts used on the "trucks" for the bearings) are 10-24 and 1/4"

Threaded 1/4" rods are what are used to "sandwich" the parts together.

The wood is all 1/2 inch plywood. Pick your poison. This should work just fine with 1/4 stuff doubled up. I am able to cut this on my 40W epilog laser in 1 pass ever since I picked up the 4" lens.

Lets be clear this is a laser man bracelet. Not a bracelet. However women can wear this if they choose. It still is a laser man bracelet.

I was trying for masonite chain link\\\\\\\'s however I am stuck on making a matching sprocket. You can see from the photo that it goes.

2 Holes, 3 Holes, 2 Holes.... This is a funky hard to make sprocket.

For now its a laser man bracelet.

I was in the need for a way to bread board a SMD TQFP 32 pin atmega168 for a project I am working on. I decided to look around for one. I found a great deal on digikey for $25 dollars.

search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=336-1505-ND

I thought that this had male headers on the bottom of the board. However it did not. It had a funky hirose connector.
See: blog.synthetos.com/arduino-boot-loader-party/

So I decided to make my own. I created the eagle footprint via a digital caliper. Which was difficult. I laserd the board and the 1/8th" masonite (hardboard).
You can see all images at my flickr stream. While you are there at me as a friend :)

So in case someone wants a cheap TQFP holder. Here are the files.

This is a single Sided approach to this board. But the version 1.1V thats in the makerbot SVN.

I tested this board by hooking up an 5v arduino + GND then ran a magnetic strip over the IC. The activity light started blinking! So it looks like everything is working. This is also my first board I have laid out that was a double sided board converted to a single. Some places are "tight" but its doable. I have ohm'ed out all my connections and everything is great.

Video of it in action here:

This is and end mill laser cut holder for the 10 piece grizzly end mill set seen here: grizzly.com/products/g9757

I use 3/4" x 3/4" x 1/16" aluminum for the supports or columns. This is a method that I invented. I call this self threading square tube insert method. The 4 holes on the masonite (hard board) are exactly positioned so that when they are all screwed in they "self thread" into the aluminum corners. The use of longer bolts will give a stronger hold. However for this project I used 2x 1" bolts and 2x 1/4" socket head screws.

The masonite used is 1/8". The top layer consists of 2 sheets identically cut (minus the engraving on the 2nd one). The first bottom layer is exactly the same as the top (minus the engraving). This allows for the end mills to "slide" into place and not move around. The last layer is the file that has the work "bottom" in it. It basically is only the outline and no end mill holes.

This is a small laser cut tool that allows you to scoop inside of the milling table to remove bits of metal that fall down inside. I have a Grizzly G0463 Metal Mill however I should think that his part will work for any similar mill table. To include Harbor Freight's version of the x3 mill.

Material was 1/8 Hardboard (masonite) but you could use any material that you think is strong enough to hold up to multiple uses.

This is my attempt to create a 608 bearing wrapper that has gear teeth on the inside. Without a belt currently this is not very useful however once I get a few belts I ordered in I will make matching inside gears. I got this idea from makerbot's older method of 1/8 plywood for their 608 bearings.

This is a mount for the Makerbot NEMA 17 Stepper Motor found here:

This is a 3Inch piece that is fully compatible with the Contraptor Project. contraptor.org

This piece is an Dremel Flex mount. This is going to be used a the Z-Axis for a CNC machine. This mount is a VERY snug fit. This will not move at all. You have to slide the flex connector up so the top slide its then the rest will just "fit".
