Many people have difficulty sleeping due either to their snoring partner, unnatural work pattern or because of living in a noisy environment.
Sleepfit™ was developed initially for shift workers who needed to sleep during the daytime, however users reported their effectiveness at reducing the level of their partners snoring to a degree where it became possible for them to sleep soundly without distraction. The durability of our product will provide years of use (most users replace after 4 years) which equates to about 5 pence per day – a small price to pay for a sound nights sleep. 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! The main problem, in most cases, is that you don't know the pinout diagram of a flyback transformer.
Harnessing renewable energy sources is crucial for supporting the energy demands of modern society. 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. So, I shall try to give you a simple method to find the primary coil input pins and also the 0 V output pin of the HV secondary coil.
The IEA calculated that global energy usage increased by 10% from 1990 to 2008, and the number is expected to rise in the coming decades. I accidentally overwritten the laptops linux OS with a new version and wiped all the working files I had for the machine. Constructed from a very soft durable silicone, Sleepfit™ is cut in such a way that it can be worn comfortably within the ear all night.
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. Ihave already done several instructables about antennas, though it would be nice to something a little different. I originally built this to power a small coil gun but it can be used for whatever you need it for.
Please note these neck cords are a device to retain the moulds and should NOT be tugged on to aid removal, as this can damage the moulds.
