Gakken World Eye & Raspberry Pi

Gakken WorldEye connected to a Raspberry Pi running a program to display a huge blinking eye.

Adafruit provide a nice tutorial on connecting the Gakken to a raspberry pi running their eyes script.

I took a brand new Raspberry Pi 3 and went here  to download the latest copy of Raspbian Stretch Lite operating system.

I then flashed the image onto a new 64GB Micro SD card

 using etcher.io.

This version of Raspbian is command line only so once the initial boot up takes place, you need to configure the wireless network access:

Once the file opens, you need to edit the contents to match the screenprint below:

Press CTRL-X and then Y to save and and exit. Then run the following command to have the file read and try to connect to your Wifi.

Now we have Internet access we can download the software to make the eye work:

At the command prompt, type the following:

1. cd
2. curl https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/pi-eyes.sh >pi-eyes.sh
3. sudo bash pi–eyes.sh

Finally, connect the Raspberry Pi HDMI output to the input on the Gakken Worldeye and run the setup. This took about 10 minutes to complete.

Build Your Own R2D2 by Deagostini Issue 88

Build time about 5 minutes.

Assemble the base panel and fit the on/off switch and recharging socket.

Build time about 5 minutes

This issue gets you to build the Dome support frame from die cast metal parts.

All done. Nice and easy!

Another big build this issue. Build time about 15-20 minutes including reading the steps in the magazine as you go along.

First step, build the tool arm..

You cant see it clearly in these pictures but I managed to put the screw into my fingers twice causing them to bleed. ouuuccchhhh!

Fit the arm to the tool compartment…

Fit the tool compartment door to the tool compartment..

Install the tool compartment to the side panel..

Now, join the three side panels together to make one half of R2D2…

All done.. One more issue and i’m all caught up!

Another longer build this issue about 15 minutes again.

Fit the side details

dsadsa

Fit the shoulder joints to the frame assembly..

This was another issue that took about 30 minutes including some testing and a small problem.

Assemble the pivots firstly.

Assemble the clutch.

Assemble the clutch linkage

Fit the arm assembly

Installing the arms…

Fit the motor

Use the Test PCB assembly again and use the buttons to open and close the arms. When I did this at first, the arms were not properly opening. I took the assembly apart again and rebuilt ensuring the clutch was properly positioned and the 2nd attempt all went well.

This was another more involved issue and took about 15 minutes to build and test.

Assemble the tool compartment.

Fit the tool compartments

Install the ultrasonic sensors.

Test the sensors by connecting them to the Test PCB’s

Testing the sensors using the Test PCB. The green LED should light up and when you block the sensor should go out.

Finally, fit the sensor panel to the body panel and you’re all done.
