In this project I will show you how to create a custom LED sign that reacts to the loudness of your music, just like a VU meter does. It is often useful to provide protection against accidental reverse polarity for your circuits.
This inexpensive torsion mount removes jitters and Jello Effect (Vibrational Aberration) from your quadcopter (I used a Syma X8) video. Usually cheap 9 volt battery connectors that you can buy are flimsy and don't last for long. My research Pure sine wave inverter using atmel attiny 13 and IR2110 mosfet driver This is my pure sine wave inverter. Every electronic hobbyist needs a variable power supply for prototyping and testing, but they can be very expensive. Some time ago a friend sent me some pictures of a printer expansion card for a brazilian ZX Spectrum. What is it all about?This project is a cheap solution to install a car or bike tracking gadget.
In today's video I'll show you a great idea, a long awaited video about how to make a Tesla coil at the minimal expenses. As some of you know that my college was having a science exhibition , their was also a project display competition going for the Juniors.
Some PCB fab houses (like SeeedStudio, with their Fusion PCB service) will allow you to panelize smaller PCBs. In this instructable, I'll show you how to build a REALLY powerful version of the slayer exciter circuit! How to memorize the Resistor Color Code The reason I came up with this is because in High School and in College they taught us the same offensive phrase, bad boys, etc, but Violet gives willingly. As any of you Chromecast owners will know, when you use the TV as the power supply for your Chromecast, your Chromecast will be on as long as the TV is on.
A friend was at a yard sale and bought a facsimile antique wall telephone that was really an AM tube radio. This instructable describes in detail the steps required to create an Arduino-based ECG simulator.
Every once in a while I come up with an idea for a circuit or device that has applications where a battery may not be the best or most convenient option for a power supply. From our build night sponsored by Jameco, this is a fairly basic and common 555 LED Flasher Circuit.
In this instructable, I will show you how to make a very basic, simple, working flashlight! Disclaimer: I'm not an electronics engineer, so I cannot offer any warranty for the design (much less for your implementation). IntroFor a while now my audio has been less than satisfactory, so I decided to do something about it.
Last week i uploaded a project on home automation ,so i borrow a led strip for demonstration .It was lying on my desk. I'm sure that you have seen those cool videos of people jamming on a box with a bunch of buttons on it.
In this videotutorial, the design of a circuit using a software simulation tool will be explained step by step. Go green with your very own power generator!Big industrial power generators make electricity by turning huge motors with coal and fossil fuels, but you can make your own with a small DC motor and some simple electrical components.
The original goal of this project was to build a functional wah pedal, using our basic electronics skills, with a simple and easy to understand circuit, designed for electric guitar or bass guitar. This little circuit measures 10mm x 10mm and is probably one of the smallest and most basic light detecting circuits around.You can use the circuit to detect light levels and for example activate a LED to switch on when it gets dark!
This paper skin turns your mini quadcopter into a General Atomics MQ-1 Predator Drone in a matter of minutes (approximately 20 from printing to flying).This is a continuation of my other instructable, which built a skin to turn a mini quadcopter into an F-14 Tomcat.


The main advantage and the actual reason of construction is the fact that residents can have access without the use of keys!The mailbox operates using a remote control. Some time ago I was asked by my father to design a light sensor circuit for him, he has some LED's installed and a solar panel and a battery array, which he then uses to power his garden lights. This is a small instructable on how to make a bedside lamp or a nightlight out of a Millennium Falcon model or any other model of that matter. Finally after a really busy time I finished a new project just a few days ago.Why to hell should I need thisMy main lab is in our stairwell, there is almost all my equipment, but sometimes specaly with arduino or raspberry I like to sit in the living room at my desk. This is the third version of my Instructable for repurposing a Lexmark E260 laser printer to print toner directly on copperclad boards.
This tool was developed with the idea to provide alternative forms of recycling PET bottles, which are found all over the world, and often not taken advantage of for post-consumer opportunities.
Hi All, This is a mini-instructable as it will be useful for some other instructables that I will post which require square holes in ABS! In this instructable, I will show you how to write a program on your calculator that will do Heron's formula for you.
A fine-spot welder is one of the few equipment where building yourself is cheaper than buying.
The device is a rough prototype of what will eventually become a self balance robot, this is the second part of the hole thing (read accelerometer and control a motor to self balance). I started this project because first time I wanted to build something like what I found on the Internet does not contain all information had to look for more projects to put them together to understand something and I wanted to be as simple and cheaper for a draft wekend. For my latest electronics project I decided to make a resistor substitution box, instead of just using another perf-board I decided to make a pcb for it so I could document the process and make an instructable.
This instructable is to show you how to make your own inexpensive tool to extract that broken boot off of the spark plug so you can continue with your tuneup. An inexpensive solution to a reasonably expensive, albeit necessary, electronic soldering accessory.
This describes an easy method to make professional looking two-sided printed circuit boards at home. This instructable show how to change parts inside a small power supply to chnage the output voltage to suite your needs. When the power supply for my Belkin USB 4 way crossover went belly up I needed a +5 volt supply capable of outputting a minimum of 2 amps. In this instructable, I will show you how to make an induction heating machine and 7 different applications for it.
The pop-up solar generator SunZilla is a renewable energy source that is portable and modular. Produce your own single-sided flexible printed circuits using a solid ink printer, copper-coated polyimide film, and common circuit board etching chemicals. As someone who likes to take apart electronic things, I frequently pull stuff like LED's, motors, knobs, and switches out of old junk with plans to reuse them later.
In this instructable you can see how an electrovalve actually works, how it looks like from the inside and how it can be used in an application that includes a water pump.In the picture are seen the parts of an electrovalve. In this tutroial I'll show you how to build - an ultra-convenient, portable bench-top power supply you can take anywhere.
What is a truss?A truss is one of the major types of engineering structures and is especially used in the design of bridges and buildings. I was helping my brother do an oil change on his motorcycle yesterday, he accidentally added a little too much oil.
I will also demonstrate how easy it can be to build a boost converter with the help of an ATtiny85.
Rechargeable batteries are expensive, as we need to buy battery charger along with batteries (until now) compared to use and throw batteries, but are great value for money.
This brief review will explore three simple methods for adding this protection to your projects.
This setup is suited for a GoPro, but the quarter inch mounting system is compatible with all tripod mounts, including point and shoot cameras.


Works great with all kind of sensitive electronics like TV's, electrical drilling machines. In order to produce a PCB layout for a clone of such board i needed some tool to make measurements based on a photo, and the choosen one was Google Sketchup. This is the last of several Instructables covering construction of this antenna that receives UHF stations and, optionally, those in the high end of the VHF band. Now, heres my first Instructable and Ill show you, how to make a small Voltage Inverter (I mean, getting a NEGATIVE Voltage out of a POSITIVE) on you Bredboard.
The pedal enables me to easily turn the page on any sheet music app I wish to use on my tablet, without taking my hands off my saxophone. Typically this isn't an issue, but we use an aerial to get our live TV and having the Chromecast on interrupts the signal.
It was while I had the TV mounted on the wall of my apartment, and kept the stand in the TV box, stored in my apartment building's storage room for safe-keeping—or so I thought. An ECG simulator replicates the cardiac waveform that can be measured by attaching three electrodes (RA, LA, RL) to the patient's chest.
It went through many revisions, saw many rule changes, and made it pretty far in development.
I only know the presented solution worked for me for at least about 5-6 months (so I can't even vouch for its reliability over longer periods). Well, today, I will be showing you how you too can make a box with which you can make jams. In fairs & contests, people roam around taking photos or video's of idea's and then in no time these idea's are copied and sold on the market.
I've added a reed switch in the electronic circuit so that when a magnet is near by, the Arc lights up which a pretty awesome effect!Check out my video of it in action! I will be really glad for all comments.Ones upon a time my younger brother David came to me and told me that he sign him self for high school thesis to develop new type of electric motor. The LM741 op-amp is an 8 pin IC chip, but I thought it would be fun to build my own on a breadboard. Whenever a visitor rings the doorbell, a Wifi Call is placed to all the family members smartphone notifying that someone is on the door.
I thought I would post how I do it - as it took me a VERY long time to find a satisfactory solution. This can be useful when you need a quick method of converting from one unit to another, especially when you do not have internet access. An old 12 volt car battery charger could easily power an LM323 3 amp 5 volt IC but it would take a week to get it. So instead of going through the hassle of draining and refilling the oil, I decided it would be easier to pull out some from the dipstick hole. It can throw really hot electrical arcs of plasma over 3 inches long, and has the capability to be modulated! Well, now you can!**An interesting observation: The other day I was using this device to listen to mechanical movements inside a machine.
In this instructable I will cover some of the main electronics components, their uses and what they look like in schematics. If you liked this I will be posting more on my youtube channel DolphinAirlines also if you enjoyed it please vote for me in the top right corner.
You can easily rotate and move the working top (or board) without using your hands - they can stay on your tools the whole time! A young maker fooling around with electricity can be particularly vulnerable to those types of accidents. I originally built this to power a small coil gun but it can be used for whatever you need it for.
