A while ago at Fablab Umeå, we had a 'CrAfterWork' where makers gathered after work on Friday to make stuff.
When I am asked a question about science, I advise people to do the experiments or to build the device and play it safe.
Figure A: Sample MaterialsSoldering is the process of liquidating lead solder in order to create a mechanical and conductive fixture between the board and an electrical component. This is an intermediate to advanced project and I do not recommend it as a first project if you are just getting started in synths or electronics.
My partner and I created this solar over as a class project, we had lot of fun designing our solar oven. So I managed to make a pretty easy and straightforward audio splitter from some spare parts. Whether your camping, hiking, biking or thousands of other outdoor activities chances are there is going to be a time when your phone or other device like an action camera, tablet or even your USB powered flashlight is dying and your miles or even hundreds of miles from the nearest power source.
Using a solar cell I managed to control the speed of the motor.I used a solar panel from an old solar lamp. Our goal is to implement a hardware-software vision system designated for home care of elderlypeople or convalescents. Excel has an electronic spreadsheet program that allows users to store, organize, and manipulate data. Had picked up a high voltage probe from a freecycler but the box also contained other random electronics including a little black box.
In this project I will show you how I converted an old LCD kit into a crude projector with the help of a couple complementary parts.
Have you ever wondered if you could use a wee little momentary tact switch to turn large high voltage high current things on and off? The basic components of the hand are the servos, the Arty platform, the glove, and the flex sensors.The glove is built with flex sensors that have variable resistors that change their resistance value when bent.
For my voice over work, I use a Xenyx 1202 4-channel mixer made by Behringer that doesn’t have a power switch. I looked for smart charger chat can charge 9V NiMH battery in couple of hours and didn't found one. Here is the simplest circuit for generating high voltage.Here i will show how to make mini tesla coil (salyer exciter circuit). This Instructable demonstrates using a 5 volt mechanical relay as a switch to control two LEDs. 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. How to assemble a PCB by hand intro: Printed circuit boards or PCBs are at the heart of modern electronic equipment. Build a Wireless Power Transmission system that can power a light bulb or charge a phone from up to 2 feet away!
Bone conduction is the ability to hear sounds by conducting the vibrations directly to your inner ear, bypassing the middle and outer ears. Invisible Fence pet containment systems require a new battery in the dog's collar every 3 months. The objective of this Instructable is to show you one method of turning DC values, such as those from a thermometer, pH sensor, or pressure sensor into a frequency which can be used to send information over the microphone band of an audio jack to a smartphone. In order to switch some floodlights by my Arduino, the small switch circuits I built around a 39mf22 were just not man enough to handle the current needed, so I decided to build a switch with discrete components around a TRIAC.
For about $5-$10 you can have your own adjustable power supply to power various electronics! Unlike Through hole resisors which use colored bands to determine the value, surface mount resistor have numbers and sometimes letters. As a kid I always wanted to have a special ability, like moving objects with thoughts or flying.
I will start out by noting that this instructable pertains only to TTL serial, and not RS232. The battery charger is originally designed by me to meet the need of some who want a 24V battery charger. Something that a project that I'm working on has me doing is using a serial to parallel IC (think 74HC595) to control leds. In this project, you'll learn how to re-purpose low-cost sprinkler parts into a high-powered CANDY CANNON.
They use the same old generic sounds to let you know when guests have arrived, as demonstrated below. But why do that when you can do it yourself, like Jason Poel Smith of DIYHacksandHowTos did.
To set the ringtone, he held the microphone up to computer speakers and recorded the sound (in intervals of 20 seconds). To make it louder, you can replace the speaker on the recording module or use it as the input to powered computer speakers.
An equivalent power (60W) iron-core version weighs over 1500 grams versus 50 g of the electronic one. It has a 1.7V voltage drop in medium-light conditions but a very low current, being unable to power the motor. My goal behind building this charger was to be able to charge a full backpack worth of the Solo's batteries (holds five) at once.
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. Through this process you can hear sounds underwater, with your ears closed, and while others are talking. It should serve well for any 2 devices that you need to have serial communications between that have TTL serial capability. However, rather than drive the leds directly from the pins, I opted for the use of transistors.
Be the coolest person on the block by building a pneumatic device that will launch candy 100 feet in the air—you can make it rain down all kinds of sugary treats!!!It's cheap to make, and a huge hit at birthday parties. Jason made his own custom doorbell chime by adding a simple recording module to a wireless doorbell system.To do this, he took apart his old doorbell and replaced the speaker with his own recording module (that you can get at any electronics store) which has its own speaker. Since the play button also functions as a stop button, the ringtone will be interrupted if the doorbell is pressed several times before the chime is finished. Charging current unknown and no function to terminate charging after battery fully charged. 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. To connect it to the radio I needed a Balun.These are such simple things but yet they cost so much from some places.
I play videogames rarely, but my favorites are car racing and open world games just like Need for Speed and Grand Theft Auto series. It's used to propel a cloud of candy to an altitude of around 100 feet, at which point the candy begins to drop back down, making it rain candy!
He connected the recording module and its own battery to the doorbell receiver by simply twisting a few wires together.
For more detailed instructions, check out his project page on Instructables.If you don't like chimes or sounds period, maybe you'd rather receive text messages when someone's at your door? This meant that the blast of air would be more effective in launching the sugary projectiles. Individually wrapped candies could be a better choice, however these jelly candies were mainly for testing the ballistics of small dense candies. And, of course, the birthday boy is the one who gets to push the detonator button!Haven't see the video yet?
