How to calibrate an MQ-2 gas sensor || Arduino tutorial ElectronFun.com 2016-03-29 | In this short tutorial I'm demonstrating how to calibrate an MQ-2 gas sensor and get your readings in ppm units. I'm assuming you don't want to spend hundreds of dollars for a calibration kit. The method shown in this video is based on a piece of Arduino code created and shared for free by a company called Sandbox Electronics.See the original video - How to use gas sensors with Arduino:youtube.com/watch?v=BIf_mpnsZvYSubscribe to get notified about my new videos:http://www.youtube.com/subscription_c...----------------------------------------------------------------------------------------------YouTube channel: https://www.youtube.com/user/electron...Google+: plus.google.com/+ElectronfuncomFacebook: facebook.com/ElectronFunPageTwitter: twitter.com/ElectronFunWebsite: http://ElectronFun.com----------------------------------------------------------------------------------------------Video, edit, voice by Chris LorkowskiMusic by RataxesUK - Everything [No Samples Edit]soundcloud.com/rataxesuk/rataxes-everything-no-samples

Will LM7805 exceed its specs? || electronics experiment ElectronFun.com 2017-03-23 | In this experiment I'm pushing an LM7805 linear voltage regulator to its limits. According to the datasheet it is rated for maximum 1.5A loads. I'm trying to check if the regulator can exceed its specs and deliver 2A or maybe even more.I'm using power resistors to simulate a relatively constant load.WARNINGThis is just an experiment. Never exceed voltage and current values provided in the datasheet. This may damage your component, shorten its life span or even cause fire.Subscribe to get notified about my new videos:http://www.youtube.com/subscription_center?add_user=electronfuncom----------------------------------------------------------------------------------------------YouTube channel: youtube.com/user/electronfuncomGoogle+: plus.google.com/+ElectronfuncomFacebook: facebook.com/ElectronFunPageTwitter: twitter.com/ElectronFunWebsite: http://ElectronFun.com----------------------------------------------------------------------------------------------Video, edit, voice by Chris Lorkowski

SSD vs. HDD - practical comparison | computer tutorial ElectronFun.com 2015-07-05 | I bet you have already heard about an SSD or solid state drive and how fantastic it seems to be. Is it really worth the price?This project is a practical comparison of an SSD (solid state drive) and 3.5" HDD (hard disk drive). Even though most SSDs are in the 2.5" format I didn't take into consideration 2.5" HDDs, mainly because their capacity is lower and they are a lot slower than 3.5" hard disk drives.Disks under test:SSD - OCZ Vertex 4 128GBHDD - WD Black 1TBTest PC specs:CPU: AMD Athlon™ 64 X2 5400+ 2.80GHzMotherboard: GIGABYTE GA-M56S-S3RAM: Aeneon DDR2-800 CL4 4GBGPU: Asus Radeon R7 250PSU: CHIEFTEC 450WProject page - you can download the Arduino code here:http://ElectronFun.com/project_6.phpSee how to install an SSD in a laptop:youtube.com/watch?v=nREFxDBSujUSee how to speed up a stationary PC by installing an SSD:youtube.com/watch?v=p4LVbeAlTwASubscribe to get notified about my new videos:http://www.youtube.com/subscription_center?add_user=electronfuncom----------------------------------------------------------------------------------------------YouTube channel: youtube.com/user/electronfuncomGoogle+: plus.google.com/+ElectronfuncomFacebook: facebook.com/ElectronFunPageTwitter: twitter.com/ElectronFunWebsite: http://ElectronFun.com----------------------------------------------------------------------------------------------Video, edit, voice by Chris Lorkowski

Buck converter vs. linear voltage regulator - practical comparison ElectronFun.com 2015-01-20 | In this video I'm comparing in practice a buck converter with LM7805 linear voltage regulator. Two driver boards from old hard drives are used as a dummy load to check efficiency and temperature of the buck converter and linear voltage regulator. I'm presenting pros and cons of both devices.There are 2 mistakes in my calculations:1. 5:02 - 5:08 - correct calculations should be: (12V - 5V) x 0.42A = 2.94W2. 5:17 - 5:23 - correct calculations should be: (12V - 5V) x 0.22A = 1.54WI double checked everything, but I should have triple checked.

How to unbrick a TP-Link TL-WR1043ND router (re-uploaded) || How-to-fix tutorial ElectronFun.com 2014-10-11 | In this video I'm demonstrating how to unbrick (recover) a TP-Link TL-WR1043ND router after an unsuccessful firmware upgrade. I'm showing the whole process from opening the case to installing firmware files through the serial console.The whole story happened a few weeks ago when I decided to download and install the latest firmware for my TP-Link TL-WR1043ND router. Theoretically everything went fine, the installation finished and I got the 'Rebooting' message. Unfortunately the router was rebooting over and over again. I realized something went wrong and my TP-Link became an expensive brick with blinking LEDs on it. I tried every non-invasive method I could find to reset the device and bring it back to life. Nothing worked for me, so I had to open the case, solder a gold pin connector and hook it up to my computer. Then I could manually upload a new firmware image to the router and install it.DISCLAIMER:If you decide to follow any procedure shown in this tutorial, you're doing it at your own risk.

How to use Atmel ATtiny85 with Arduino || Arduino tutorial ElectronFun.com 2014-09-10 | In this video I'm demonstrating how to program and use Atmel ATtiny85 with Arduino code. If you have a small Arduino project and need only few input and output pins, you can substitute the 28-pin Atmega8/168/328 microcontroller with the small, 8-pin ATtiny85 chip. You'll save some space, simplify your project and decrease power consumption.The ATtiny85 microcontroller offers digital, analog and Pulse Width Modulation pins.By default Arduino IDE doesn't support the ATtiny chips, but High-Low Tech Group at MIT Media Lab created their own libraries and shared them publicly.

How to build a simple Arduino on a breadboard || Arduino tutorial ElectronFun.com 2013-12-29 | In this video I'm demonstrating how to build a simple Arduino on a breadboard, based on Atmel Atmega8/168/328 microcontroller.When I build my Arduino projects usually I don't need the whole Arduino board and all of it's functionality. In many cases I use only basic input and output pins and that's why I assemble a simplified version of Arduino.When connecting your Arduino to a power supply or a battery make sure that you connect the red jumper wire to the positive terminal and the blue one to the GND. There is no protection against reversed polarity and you may blow something up.The circuit diagram for this project is available on my website:http://electronfun.com/project_1.phpMy build is based on:arduino.cc/en/Main/StandaloneIf you want to know how to program a simple Arduino on a breadboard go to:youtube.com/watch?v=wk68-quAci0See all my Arduino tutorials here:youtube.com/playlist?list=PLGyIrno2GXdyPPNNB4UEnoMshQmWRv6AzSubscribe to get notified about my new videos:http://www.youtube.com/subscription_center?add_user=electronfuncom----------------------------------------------------------------------------------------------YouTube channel: https://www.youtube.com/user/electron...Google+: plus.google.com/+ElectronfuncomFacebook: facebook.com/ElectronFunPageTwitter: twitter.com/ElectronFunWebsite: http://ElectronFun.com----------------------------------------------------------------------------------------------Video, edit, voice by Chris LorkowskiMusic by Jason Shaw - Rhastafarianhttp://www.audionautix.com
