I created the location-food clock as a way to notify my mom about where I am and whether or not I have eaten the appropriate meals for the day. It uses the location from my smartphone and turns the clock hands to one of three positions: Home, School or Elsewhere. The hands of the clock have three lights accounting for the three meals of the day. Whenever I have a meal, I press a button on my phone (using the IFTTT app) and the appropriate lamp lights up. At the end of the day, if all three lights are on, my mom would be relieved and happy to know that I have had food throughout the day. At midnight (my local time), the lights would all turn off.
Here is a link to my instructable post.
I have a couple of ideas as of now and I am still unsure which one I would go ahead with. But I want to do a project connected to the internet and use servo motors to have some mechanical action. Here they are:
1.”Where are all the Adyas?” clock:
This one is inspired a bit from the Weasleys’ clock from Harry Potter which shows at a glance where all members of the family are. I have wanted to do this project 6-8 years ago when my mom would call me, my dad and sister always asking if we had reached school or office and if we had lunch. So my idea for this project is to have three sections on a “clock” named “work/school”, “home” and “elsewhere” and have four hands for each member of the family. The circuit looks for the location or each family member using their smartphones and using IFTTT, triggers a servo motor to move the hands on the clock to the appropriate location. I also want to add a way to let my mom know that I have had lunch/dinner. I haven’t quite figured out this part yet.
Here are a few links that I looked at for inspiration/tutorials:
2. 360 timelapse rig:
I want to create a camera rig to capture 360 timelapses of an object over time, like a flower blooming or food decaying (example
). I would use the arduino and a servo motor to move the camera physically one step at a time based on a pre-decided interval and depending on which camera I am using and its battery life, when the battery is at 15%, it sends me an email/SMS to change the battery. Building the camera track I think should be relatively easy for me since I have built one in the past. But I am unclear how difficult or easy the arduino bit would be in this project.
Based on which project I decide to go ahead with, the parts I require will change. But I would definitely need a WiFi shield
and a servo motor (may be more powerful than the one included in our kits).
The frame lights up by interacting with the origami birds. Each bird needs a different kind of interaction to make its counterpart light up in the frame, depending on the sensor. There are three different sensors: Hall effect sensor, force sensitive sensor and a light dependent resistor.
Here is my working arduino circuit:
I started by first making the individual circuits work independently and then combined them into one sketch to work together. The next thing was designing the frame itself based on which birds I wanted to make. I made a lot of different birds and ended up with the three seen below. The reason for these was aesthetic appeal as well as level of complexity which would let me/the user to interact with them in multiple ways. I then laser cut the frame graphic and made a box with partitions to block light from one bird to the other. And finally I added all the lights within the frame.
I wanted to use neopixels as the light source, but I couldn’t get them to vary their brightness based on the inputs and they were at fixed brightness. So my next step will be to incorporate those and make the divisions in the frame for all the birds.
The idea is to have lights behind each piece and have different switches connected to each of them. This way I can explore different kinds of switches and be able to make a final product which can be displayed and interacted with.
The idea originated when I thought about making a 3D version of the Join-the-dots game and using LED strips to create a shape which light up when connections are made.
Another idea : I want to try and make this thing on the Netflix website.
I found a mini error in the code for the potentiometer circuit (Circuit 08, Page 23). In the “Making it better” section, for fading the LED, int sensorPin = A0 should be replaced with int potPin = A0.
I went back to the original idea of making a lamp which reminds me of fall.
The best way I found to attach the leaves to the coil frame was to weave them in a thread and then tie it onto the coil. Once I did that, I wasn’t very happy with the light diffusion and the physical appearance of the lamp.
So I decided to cover it with a white cloth and see the effect that it created. Once I was convinced of the idea, I stitched up the cloth with supports at the top and bottom and then inserted the lights into it.
The light source is a strip of LEDs stuck on four sides of a cardboard tube. It is powered by 8 AA batteries (12V DC) and can change to multiple colours depending on the mood.
Even though I like the way the lamp looks when lit up in the dark, I am really disappointed with how it looks otherwise. I might have to make another version of the outer cloth and may be leave the bottom open for a more light and airy feeling.
For everyone who’s using LED strips, I found this guide helpful to power it based on the length and specifications of your LED strip.
