In this Instructable (my first) I am going to show you how I built this ridiculously bright handheld LED flashlight so that you too can turn night into day... and impress your friends.Most of us use flashlights quite often for activities like camping, walking at night, or simply just going outside in the dark. However, the majority of us settle for those cheap value packs from the checkout at the local hardware store. These cheap flashlights produce a useless amount of light if any at all. To resolve this issue I designed and built this crazy bright, surprisingly useful, and very impressive flashlight that is great for lighting your way in the dark, creating cool video and photography effects like sci-fi glowing orbs, using as a work light, and many other things, all for a reasonable cost.
Welcome to my first instructables page. A year ago I got introduced to the wonderful world of Arduino and electronics. I have learned a lot from this site and this seems a great place to show my projects. I hope you find this project entertaining and helpful. I'm eager to know what you think. Let me know in the comments, please keep in mind I'm a beginner and not a native speaker. All of your comments are welcome ;) The projectI few months ago my night lamp broke and I was looking for a replacement. Then I thought: why buy one if I can make one! My first intentions was to use an Atmega328 but this project required only a few pins and I wanted the built be a cheap as possible. So I did some research and ended up with an Attiny85. My self-built night lamp has 3 knob
Maybe you picked up a Raspberry Pi for the holidays, or you’ve been sitting on one of the super versatile, palm-sized computers for a while now. If you’ve been wondering how to get started with yours, or what you could build that’s worthwhile, here are ten great ideas.
This Instructable is meant to be a supplement to a video I made on the same topic, which can be found here: I recommend watching the video for a summary, and to see some interesting stop-motion impacts, and then use this guide for details on how to build your own setup. High-speed droplet photography is an awesome convergence of science, photography, and art. The main idea is to capture the complex fluid dynamics that occur when droplets impact surfaces of water, each other, the splashes of other droplets, the films of soap bulbs, and many more interactions. It sounds nerdy, but for some idea of what results can be obtained, even for a complete novice like myself, take a look at the photos above. If you're not convinced, check out these photos taken by people experienced in the art of droplet photography:http://twistedsifter.com/2014/01/high-speed-water-...The goal of this Instructable is to introduce peopl
This project was inspired by Apples recent addition of the touch bar to the new Macbook pro. It runs on Arduino Nano and interfaces with Processing via USB connection, creating a unique + intuitive way to interact with my Laptop.It has a 5 button interface which allows me to launch apps, open folders and pull up my favorite websites with a quick button press. This version currently gives me to access 24 different functions which are divided into 6 categories of 4 functions for ease of use, these categories include: Tools, Media, Browser, Utilities, Social and Lifestyle. Categories can be navigated through using the small button on the side and each category is visualized with a unique color by an RGB led within the device, illuminating the plastic buttons from underneath. These colors allow me to associate which category the software is in without looking at the screen.As precedent fo
Retro look accurate digital clockThis digital clock uses 4 display wheels to show the time. I used birch plywood for the cabinet to give the outside a nice look. Side panels are made of dark hardwood for a good contrast and the whole was finished with a silky varnish, not to make it too shiny. The clock is operated by inexpensive small stepper motors controlled by a arduino mega board. Each wheel has its own stepper and driver to change the numbers for each digit.To get a uniform display for all digits, the wheels were made identical to each other although the tens of hours only requires to display 0 to 2 and the tens of minutes 0 to 5. It is also easier to make 4 identical wheels with the same gears, mounting etc. One could decide to omit engraving the digits not required but it is less complicate
In this tutorial I'm going to show you how I made a wifi switch from scratch (or almost) using the well known ESP8266.The idea is the following: I want to be able to turn on/off several lights or devices connected to the power supply from my phone. I don't want the switch to rely on a battery. The switch will need to connect to 1 of 2 preprogrammed wifi. I want to be able to make groups of switch, and turn them all on/off by the push of 1 button. I want to be able to turn it on/off at a specific day and time using a timer. And I don't want to pay more than a total of $30 per switch, since I want to make a dozen of them.The components won't be put on a breadboard, but rather soldered on a PCB, in order to make the switc
Drinking enough water is very important for our health. Drinking more water can lead to clearer skin, better overall health, improved productivity and brain function, increased energy levels, and even weight loss.In our busy life it is really hard to remember to drink enough water and most of the time we forget to drink enough water either we are in home, office or on the go. Around 75% of Americans are chronically dehydrated all the time. So, in order to build a healthy water drinking habit, it’s important to track your water intake every day.To track my water intake I made my water bottle smart using Arduino. It can:1. Track my daily water intake2. Track my weekly average water intake3. Remind me to take water4. Track last intake time5. Run more than one month in a single charge. Demo Video
It all started when I stumbled across Harifun's tiny LED cube almost 10 month ago. He has done a great work on miniaturizing Ashler Glick's innovative charliecube, which uses charlieplexing to control a 4x4x4 RGB LED cube with nothing but 16 IOs - no driver circuitry needed. Despite being the smallest cube to that day, I was aware that there are even smaller LEDs, so - technically - it should be possible to shrink it even further, right?! But the more important question is: What is the smallest thing that we makers can build, at a reasonable budget and with humble tools? This project was a quest to figure it out! The final result is so small that it could be worn with a necklace, but I use mine as a key fob. While most of this project is fairly simple, everything soldering related is a tough. It's not impossible
