We have received the Laser Protection Windows.

We finally automated the laser cutting by using a digital to analog converter (DAC), connected via #I2C to one of the sensor ports of an #LEGOMindstormsEV3. We created a custom board featuring a #Adafruit #MCP4725 DAC.
After some tests to verify everything was working correctly we hooked it up to the laser to do the very first automated laser run. We are very proud that everything is controlled by only one EV3 Brick programmed in Java using the LeJOS firmware.

Today the paper cube team has worked again.
The aim was to test the laser for cutting and slitting the paper. With the help of a small Java program, the motors of the cutting unit has been activated and a test is performed. We are very pleased with the initial results. What do you think?
Jens and Fabrice are members of the papercube project team. In the last days they have been working on our „Module 1“ (The CuttingModule . The carriage with the pencil is used for training purposes in the Java lecture . Later, it is replaced by a laser module . Then it’s possible to cut the paper . The film can be seen exactly how the unit works . We are always impressed how accurate can be constructed with LEGO.
Today the paper cube team has worked again: A part is currently working on the revision of the cutting module . The other team members revise the gluing module. The entire unit is now mounted on a carriage, to apply the adhesive on each point of the paper can.
The special feature of the unit is the contactless gluing. The adhesive is applied by means of pneumatic onto the paper. Therefore we use a small 3-way valve. More on this later 🙂
It’s time for a sign of life from papercube.
On the photo is no LEGO!!! Correct!
But we prepare just a test for a laser diode.
We would like to cut the paper with a laser.
The time of the exams at the university is over.
Yeah !!! Time for working on papercube!!
