Since we launched, we have been working on a demonstration to show you all the FR4's ability to machine circuit boards, since that is an awesome and practical application for the machine. As you can see in the video, we used EAGLE to design a circuit board and generate a toolpath for the FR4. We found that we can effectively cut traces down to 12 mils. Since we already had a super cool Adafruit microscope attachment set up, we used that to assess the quality of our work.
As you know, we are about 2 weeks into our Kickstarter campaign for the FR4 Machine Shield. So far, things are going great and we are currently at about 88% of our goal. If you're thinking of backing, you have until August 8 to do so.
For those of you who have already backed us, thank you! We are very excited to be able continue working on this product and hopefully bring it to market. A couple of reminders for those of you who already backed, the Arduino and soldering iron(which you will need to complete the machine) are not included in the base reward tier. You will need to add money to your pledge for those add-ons. Here's some examples.
If you live in the U.S. and you pledge for a Super Early Bird kit and you need an Arduino and a soldering with it you should pledge: $350 (super early bird kit) + $115(soldering iron add-on) + $30 (Arduino add-on) + $20 (shipping) = $515
If you live outside of the U.S. and you pledge for an Early Bird kit and you need an Arduino you should pledge: $375(early bird kit) + $30 (Arduino add-on) + $100 (shipping) = $505
A note for international backers: the soldering iron we will be shipping is for 110V power. If you have different power where you are, it may be better for you to source a soldering iron locally.
