Stabilize Sensor Readings With Kalman Filter

We are using various kinds of electronic sensors for our projects day to day. IMU, Ultrasonic Distance Sensor, Infrared Sensor, Light Sensor are some of them. Most of the times we have to use a processing unit such as an Arduino board, a microcontroller chip to process the sensor data and get corresponding outputs. If we observe these readings we can identify that those are not very stable and contains noise. If we use these noisy and unsta...

Unusual Uses of a Drilling Machine

Necessity is the mother of inventions... When the need for something like a tool, spare part or an equipment, which is not readily available with us, becomes very essential we are forced to find ways of getting the work done by what is available with us. Some times the way we manipulate what is available with us In this instructable I have demonstrated how a variable speed Drilling Machine can be used in unusual ways like cutting weeds, dig...

Image to Low Poly Vector Art

To create the framework, Inkscape uses a plugin that generates a path between objects. Make sure to save before this step! Using the selection tool, drag a selection box over all of the dots (but not your image), then go to the drop down menu "Extensions", "Generate From Path", and "Voronoi Diagram". This will open a menu, where "Delaunay Triangulation" should be selected from "Type of diagram". Upon clicking apply, Inkscape may freeze up f...

Galaxy Sloth Custom Helmet

Two days ago, I made the Galaxy Sloth Skateboard. I rode it around a bit, wiped out a few times, and showed off to my friends - not necessarily in that order. I was having a great time and feeling like a total boss, until one of my friends said something like "if only your safety gear was as dope as your skateboard". I realized immediately that what my life was missing was a matching Galaxy Sloth Helmet, and that it wouldn't take too long t...

Online Herb Hydro Grow

Background Hello boys and girls! This project comes from the need of quite a lot of fresh herbs. The best way to achieve this by growing herbs in water. However, unlike normal soil grows, the plants can't survive very long if they run out of water. To ensure that the plants always have water even while I'm away I needed some way to monitor my plants. I can check in on my plants using any browser while I'm away and at home I use "steam Wall ...

1/4" Audio Jack Key Holder

For this step I just laid the project on it's side like in the first picture and got it fairly even on both sides just by eye. Then I carefully moved it to the glue table and put plenty of glue on all the joints. After waiting a bit for the to become semi-dry and more stable I sanded it very carefully and slowly. I did this because I wanted the wood dust to stick to the glue and patch whatever holes were left from the odd angle of the box j...

Generate Electricity From Walls!!

Generate Electricity From Walls!! Surprised!?Well,It is possible to make electricity out of walls ..but it will work only in very cold or very hot climates. You should have possibly guessed by now that Thermoelectric cooling is the principle. Peltier effect can make this possible. Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials. IN COLD COUNTRIES: People use heate...

Double Pendulum Fidget Spinner

During the design process my main concern was to make the spinner small enough so it could be held in a hand. I also wanted to keep the it very simple, but pleasing to look at. You can of course go crazy with it. I started out with 608 (8 x 22 x 7 mm - inner diameter x outer diameter x thickness) bearings (these are the ones used in skateboard wheels and most fidget spinners), but quickly had to realise that they were to big. So I decided t...

Event information at gmail via Bolt and Proximity Sensor

This project is made for those who want to know about some event occuring with their devices via online services. IFTTT is a simple language, stands for " If this then that ", which enables us to connect to services so that, whenever something occurs with our devices, a trigger goes off and an action takes place automatically, which basically informs us about the event. The services may be any service eg. Facebook, Twitter, Instagram, YouTu...

Laser-cut Pinwheels

I honestly thought this would be a fun, hour-long project. How hard could it be??? Well friends, the internet led me astray. First of all, don't trust anything that says you can use brass brads. That's fine for decorative pinwheels, but they won't spin! There's too much friction with the edges of the brads and the paper. I included the design I made in case you're looking for something more decorative. Second, don't use a straw for a handle...

Copper Pipe Table Lamp

If you're using an extension cord like I did, start by cutting off the end using your wire cutters . Don't cut of the end that plugs into the wall (yes, I actually did that by mistake once) but instead remove the other end. The wire will end up being shorter once you've threaded it through the copper pipe, so you'll want a cord that's at least 10 feet long to begin with. Thread the wire through the small hole on the side and up through the ...

Steampunk Rubiks Cube

I laser cut the veneer, because it was way faster to do so, but you can also carefully use a knife. An even easier way is to use vinyl that looks like wood. I uploaded the file I used for laser sutting should you have access to one. Congratulation, you are done. Original link

Attempting to Grow the Carolina Reaper Chili Pepper Plant

If you plant is health and growing well it should eventually flower. Mine started flowering around 4 months of growing. At this point the flowers need to be pollinated, this is done by using a small artist brush or Q-tip and transferring pollen from the anthers to the stigma. The theory is to rub the inside of the flower to grab the pollen an then place it on the stigma. I had a lot of blooms and I tried a few different ways but unfortunate...

Laser Cut Leather Fitbit Band #1- Charge 1&2

I am not sure what laser you are using but I used a ULS. The preset suggested powers worked great. Just make sure that you enter the median thickness for the leather so you don't over cook the leather. You may need to really watch the material is it cuts out. Some processed leathers will curl and char. You may need to adjust power or speed to combat this. I threw some funky gothic art on the band just so there was something more interesting...

Macro Lens From Old Phone (with Hot Glue Casing)

For this step, I removed all the screws I could see. I put them separately from the previous screws so that I could differentiate between them while reassembling (which never happened :D). There will also be some buttons such as the camera button which you can remove and put aside. After you have removed the screws, you will see some orange colored, wide cables attached to it. To remove these, just gently push upward from the bottom with a ...

Complete Bathroom Overhaul

The hardest part of this entire project had to be changing the plumbing from the old urinals, All of this tile and concrete has been in the building since the mid 30's, so its all gotten very hard, as you'll see in later pictures I actually chose to frame out stub walls to hide all the plumbing and electrical because the walls are concrete. The old plumbing for the in ground urinals was completely plugged up, I brought out roto-rooter and t...

Felted Soap Bars

Begin with wrapping wool around your soap in one direction (say, vertical). Spray (or dunk) your wool covered soap with hot water and place the tulle over the wool, gently rub the tulle into the wool in small circles, heat and soap helps wool to felt (stick together). You'll know the soap is well felted when the tulle lifts off the soap without pulling up the wool. If the wool does pull up, spray it with hot water and continue the circles f...

Using an RTL-SDR Dongle

You'll need to install some dependencies first, which we need to properly connect to the RTL-SDR stick. Open a terminal window, and copy-paste (or type) one line at a time, then press enter. Wait for all output to finish printing before entering a new line. Some steps might ask for a confirmation to download; often this requires typing 'Y' or 'y' and then enter. sudo apt-get install libusb-1.0-0-devsudo apt-get install git sudo apt-get inst...
