Did you make the night light using a phototransistor in 123D Circuit?
Yes, I made the original night light circuit in 123D circuit. Here is the project as it transferred from the bread board, but then in the second photo it shows that I had to change to make everything not cross. I also had to change some of the components to match the ones we had a school.
Did you make the night light using a phototransistor with a breadboard?
We made the night light with a breadboard by following the schematic image on the mad scientist.
Did you make the night light using a phototransistor in a circuit?
I built the protoboard by following the bread board that I created earlier.
Did you make the night light using a phototransistor in a PCB board?
I made the night light on the other mill using the PCB board. I had to try twice because on the first one I forgot a trace.
The second worked and the night light dimmed in the sun. I was not able to see a change when I used the lights in my box, but the circuit worked by itself and the lights kinda lit up the box in the second video.
I made a second one after that I was originally going to use as the top of my board. But then I decided to go a different path.
What is your container for your nightlight?
I wanted to make a Doctor Who nightlight. I was going to use the files and directions given on the Instructables, but I had to modify it because it did not quite work. This is the link to the Instructable and here are the SVG's that I modified from the original.
I first started by trying to cut my Tardis out of cardboard at school, but unfortunately, it was not successful. The laser was unable to cut through the material (cardboard). I tried again.
I painted the cardboard pieces that were supposed be printed in acrylic for my mock up. This was so I could tell the difference between what was supposed to be wood and what was supposed to be acrylic.
I tried printing my box out on the school laser cutter, but it didn't work. The laser could not cut through cardboard, and I ran the ten-minute program 3 times. After trying this twice and wasting and hour and a half I decided to go to maker space to actually cut my project.
This is the laser cut result in cardboard so I could make my mock up. I divided into the separate layers in order to make it easier to build.
This is the top of my box. This is the top that the guy designed and I decided after trying to put it together, that it was over complicated for the purpose that I intended to use to for, so I completely changed the top of the box to something much simpler. The new top will only have a simple three layers to make it have the effect of going up and one of these small pieces that require small little sticks that it needed in the Instructables.
I finished the mock up with cardboard and decided what I wanted to change before I started working with wood.
My mom and I worked on measuring the wood because the piece we had at home was way too big to fit in the laser cutter. Then Mr. Scott helped me use a table saw to cut it into pieces.
This is the photo of the laser that I cut at the Maker space. I went there cut to wooden version.
Here is the cut out of what I worked on Thursdays March 10th after school. I was successfully able to cut out all of my pieces from wood. I also cut out the special top that I designed myself and the extra pieces to give the door some depth perception. Finally, I cut out the pieces for the signs that will hand on the doors and the big base pieces. The only problem I had was that on parts of my piece of wood it was a little warped, so the laser was only able to cut through part of it. To fix this problem, I used an Exacto knife to cut out the rest of my wood.
Catherine and I worked for two days in class to finish gluing the box together. I also stained the box blue to give it more of a Tardis look.
Did you create a workflow for using the Other mill to make a circuit board?
- A step by step set of instructions with pictures.
I used the othermill to cut my board so all I have to do now is solder it together.
4/12/17- I took my night light home to try and finish it over the break, but when I tried to solder the board together, I learned that I was missing a trace line between the transistors and for that reason I could not finish my night light electronics.
4/18/17 - Today I worked on creating my other mill board. I was able to fix the trace problem and recut the board.
How did you create your container?
I created my container by using a laser cutter and cutting the doctor who box out of wood and then staining it with blue stain and glueing it together.

Work Flow for the Othermill:
1. Step one: Export your board from 123D circuit. To do this download gerber files and unzip the folder. Than place it in google drive.
2. Step two: Go into the othermill computer room. Click open files:
3. Step three: Select the .gtl file from the folder. It should be the only one that you are able to select.
4. Step four: Select only the traces and holes. Do not select the outline. Also make sure that the two bits that you have selected are the 1/64in bit and the 1/32in bit.
5. Step Five: Place a sheet of copper from the bin labeled one sided PCB board. Than place the double sided tape onto the back of the board. Peal back the take on the board. Click load on the screen in order to place the sheet into the machine.
Step 6. Click start milling on the bottom and it will prompt you to change the bit. In order the change the bit. In order to change the bit, take the two wrenches from the top. Place the bigger wrench at the bottom and the smaller wretch at the bottom
