I went to an REI garage sale a few weeks ago, and I picked up an awesome $50 bike speedometer for only $5! I often bike with a group of friends, and it is cool to see my speed in real time. It would be awesome if they could do the same, but none of us want to pay full price. This is what motivated me to try to make my own.
One of the primary ways we perceive our environment is through vision. Each of our eyes contains a lens that projects the 3-dimensional space around us into a 2-dimensional image on the retina. As time evolves, we see the space change around us. Therefore, time is sometimes considered another dimension along which we can perceive our environment. Like our eyes, cameras also consist of a lens that projects the 3D environment onto a sensor, with the added ability of storing the 2D projection as a picture.Instead of visualizing the universe as a 2D spatial projection onto a sensor or retina, you can also imagine viewing the universe along the time dimension. With this visualization of the universe, an image has a single space axis and a time axis as opposed to two spatial axes (see the diagram). These images can be called space-time images, and they enable you to visualiz
“Take control”, this is the watchword of the contest in which I participate with this my first INSTRUCTABLES.Just take control, it is the purpose of this project. Taking control of our home, of our office, of the electronic devices or also of the home appliances. But take control means having the command, and have command means to giving orders, and what better way to give an order, of a direct and instant voice command?Voice commands, because of their immediacy and simplicity, are becoming more common and integrated, but how can we exploit it?An ARDUINO is enough! Just harness the microphone and the speech synthesizer of a common smartphone / tablet Android to control an Arduino with our voice, letting him do the rest.--The video of how it works--Here are the macro steps that will follow:-1 COMMAND AND CODEFirst of all we decide what to do with Arduino, to the even

Panorama Controller for GoPro CamerasThe controller will rotate your GoPro over a set angle for a set duration or will rotate you GoPro for a full rotation for a set duration.This project is based on the original instructable by Tyler Winegarner See instructable here and also from Mark Wheeler's version of Tyler Winegarner's instructable See Mark Wheeler's instructable here or his web site here .My instructable combines software and hardware from both versions as well as adding some different build and control options of my own. further details on my web site.I have added code for a 4x20 I2C LCD display and switches rather than the SainSmart LCD Keypad Shield. I have also removed the Arduino UNO shield and replaced it with an Arduino Atmega 328 mounted on vero board. Full schematics and vero board layouts included.The Arduino controls a Geared Stepper Motor 28BYJ-48 via a ULN2003 Stepper Motor Drive
An electrocardiogram (ECG) is a test which measures the electrical activity of your heart to show whether or not it is working normally. An ECG can reveal a wealth of information about cardiac regulation, as well insights into pathological conditions. An electrocardiogram can be a useful way to find out whether your high blood pressure has caused any damage to your heart or blood vessels. If you have any heart disease such as high blood pressure, or symptoms such as palpitations or chest pain you may require a routine ECGs. Demo Video:In this instructables I will show you how you can make your own 3 lead ECG machine very easily (no complex circuit!!!).I tried to keep it very simple so that you can easily reproduce it. No complex circuit, no complex soldering!.

We've all read it. "Sitting is the new smoking", "Sitting is killing you", etc. Regardless of what the studies and headlines show you I think it is pretty easy to agree that sitting on your butt all day isn't healthy. Many of us with desk jobs do exactly that for 8+ hours a day though. I work in front of a computer most of my day and I know that my back starts to get sore, my posture sucks, etc after getting into "the zone" and working away for 2-3 hour stretches. I'm always looking for an excuse to make something and thought a simple reminder to get up and walk around or stand and work (at a modular sit/stand work station) would be a pretty good thing.Furthermore, I have Type 1 Diabetes which is an autoimmune disease in which my body decided to attack my pancreas and kill of
Now that you’ve heard about the Arduino Microcontroller and maybe even run out and bought one, how do you do things with it? When you’re just getting started with tinkering, the questions can be non-stop. Obviously, a sense of patience and curiosity are staples, but everything else is something you can learn, so here are my Top 10 Basic Arduino Must Know Factoids to help you get tinkering! Throughout this Instructable I tried to include some basic code to use with the components. It is not the complete list, just a good starting point. Watch the punctuation and caps, they matter (I think I caught any mistakes), you do not need to indent, I did that to draw attention to the code used in a routine or section.When you’re ready to move on and want more, I recommend Arduino.cc and Adafruit.com as the best 2 places to start but loo

I was looking for a straightforward clock to use with a 128x64 OLED I got from Adafruit but found that a lot of the implementations were too cumbersome, involved a ton of code, weren't clear on what NTP servers to use and how, and basically offered very little in terms of making a clock with the LOCAL time (not UTC, which is easy enough to get). So I set about doing my own research and ended up with this simple clock that leverages already made libraries to minimize the code footprint, while offering some interesting tweaks in displaying the time (like AM/PM, 12-hour format, names for months, days, etc). This instructable assumes you have some experience programming ESP-01s but if not, there are a ton of wonderful tutorials available on Instructables! Enjoy!
You’re building an IP, subsystem or SoC and you want to use a prototype together with a software testbench to drive extensive validation testing. I’m not talking here about the software running on the IP/SoC CPU(s); what I mean is the testbench you want to use to wrap around the whole system. This is a very common requirement. An obvious conclusion is to hook the prototype up to a host PC, run your testbench there and connect to the prototype through one of the standard interfaces. 19636 But there’s a problem. Your real design probably has all kinds of communication interfaces to the rest of the system to which it will ultimately connect, yet you’re constrained to pushing all that testbench activity through a relatively narrow pipe between the prototype and the PC. Wouldn’t it be nice to have wider and more realistic channels to connect the testbench to the DUT?
The rapid growth in numbers of IoT devices has seen them become a favored attack route for cyber criminals. This has left companies looking for a way to integrate strong security into millions of devices.
Internet of Things Toilet uploads flush events and toilet paper roll change out events to Google Drive spreadsheet.How does it work? – An aquarium liquid level sensor float switch detects toilet tank level; flushing lowers the level closing the switch. A photo cell located in socket (blind hole) of the toilet paper holder spindle mounting arm detects when the spindle is removed to change out the toilet paper (letting light hits the photo cell, thus "closing the switch"). Signals from these two sensors are sent (wirelessly - despite what the intro photo implies) via a hacked two button key fob; that is, sensor switch closure effectively pushes a button. A 315 MHz receiver module connected to a Raspberry Pi receives switch closure signals.The Raspberry Pi, using Python API gspread, transmits the event data to Google Drive spreadsheet.See system layout image.How hard and how much $ ? - Assuming you alread
