How To: Make an infrared heart sensor

This video shows how to create an infrared heart sensor using an Arduino controller, a couple of resistors, and an infrared light emitter and detector. This device will be used on the subject's finger, detecting the amount of blood which is flowing through the subject's finger. The amount of oxygenation of the blood is shown in the finger, which will cause the infrared light to reflect off the skin and to the transmitter which is close by. The fluctuations of oxygenation are picked up by the ...

How To: Prepare a wall for drilling

In this video we learn how to prepare a wall for drilling. First, check for pipes and cables in the wall using a digital detector. After this, it's a good idea to tape some masking tape with an envelope on the wall to catch and dust and debris that falls off while you are drilling. When you're finished drilling the hole, remove the envelope from the section you are on and continue on to the next part of the wall. It's just that easy to drill a hole in the wall once you know you won't be hitti...

How To: Prepare your home for winter snow fall

In this video tutorial, viewers learn how to winterize their home. Users should begin by cleaning the gutters on the side of their house. Scoop out all the debris and seal it with caulk. Then change the batteries of the smoke detector and clean it. It must be replaced if it is over 10 years old. Prepare the lawn mower for the spring season by sharpening the blades, clean it and drain all the gas out. It is a good idea to trim off the shrubs and trees. This video will benefit those viewers who...

How To: Make an SMS Intruder Alarm

This tutorial shows you how to create an intruder alarm that sends you text message alerts when motion is detected. This may sound complicated but I am pretty confident any beginner with electronics should be able to do this just fine. The range sensor senses motion and tells your Arduino board to send the text (SMS). So you can leave the intruder detector at home, connected to your network, and still receive the SMS alerts, no matter where you are, as long as you have cell phone service.

How To: Perform the "tell the truth" card trick

This video shows you a mind-reading card trick. This particular trick requires 8 cards: 4 kings and 4 queens. First, the subject is asked to memorize one of the 8 cards as they are laid out before the subject, face-side up. The cards are picked up and sorted in various ways and the subject is asked a series of questions. The questions are always asking whether the card the subject memorized is in a certain group that the trick performer presents. The card in question always is in the group th...

How To: Install a sprinkler system properly

Tim Carter of AsktheBuilder discusses all new fire sprinkler design and how to install them. Automatic fire sprinklers can be installed in a new home or your existing home. Smoke detectors are good, but fire sprinklers along with the smoke detectors are better. These sprinklers can protect you and your family from fires, which can be extremely destructive.

How To: Protect Yourself Against Black Hats! [DEFENSE SERIES PART 1]

Hi! Let me get started on this subject as it is a very "touchy" subject. We all want to "hack" these days, and that's logical. Te be real honest here, i was inspired once by the words someone from the Null byte community said. In the (near) future, wars will be ended by computers and not a nuclear missile. That's something i really do believe in. But let us take a defensive measure instead of the offensive one. Sure, Full frontal bryte forcing is an option, but when it'll come that far we'll ...

How To: Block RFID Signals, Build an RFID Reader Detector, and Make Custom RFID Tags

RFID chips are everywhere. They're in passports, credit cards, and tons of items you've bought in the last 5 years or so. Big retailers like Walmart started using tracking products with RFID as early as 2004, and today, they're used in everything from mobile payments to hospital record systems. Chances are, unless you're a hermit (in which case you wouldn't be reading this anyway), there's an RFID tag within a few feet of you. Photo by sridgway

How To: Turn JavaScript on in Internet Explorer

In this video, you will learn the steps to take to enable JavaScript in Microsoft's Internet Explorer (IE) web browser. Although JavaScript support is typically enabled by default in most modern browsers and many web applications depend on JavaScript being enabled to function properly, some persons and organizations may occasionally disable JavaScript to negate the effects of annoying or insecure implementation of JavaScripts on some web pages (such as pop-ups, hidden tracking links, unwanted...

How To: Find gold in rivers and streams

This film is about gold. Gold diving. Use of the hookah rig to find gold. Gold flakes, nuggets, and platinum nuggets are shown. Gold and platinum are 15-19 times heavier than other streambed materials and concentrate in low pressure areas and cracks that run across rivers and streams. You look for a crack on the bank, and follow it out until you meet the "gold line" and there you suck it out with your dredge. Gold will be on the outside edge of a river gravel bar, at the head of the bar (larg...

How To: Detect & Classify Wi-Fi Jamming Packets with the NodeMCU

The most common Wi-Fi jamming attacks leverage deauthentication and disassociation packets to attack networks. This allows a low-cost ESP8266-based device programmed in Arduino to detect and classify Wi-Fi denial-of-service attacks by lighting a different color LED for each type of packet. The pattern of these colors can also allow us to fingerprint the tool being used to attack the network.

How To: Make an Automatic Minecart System in Minecraft

Summer is over and autumn is here. Serotonin levels are dropping and people don't have the motivation to be outside as much anymore. So we play Minecraft instead. But walking is cumbersome, so we want minecarts. Remembering to carry one in your inventory or placing one on the tracks might be a bit much to ask for, and don't even get me started on bothering to press a button to make it go.

How To: Install Drywall Anchors

Wall Anchors. Drywall Wall Anchors. Plasterboard Wall Anchors. I discovered these plasterboard (drywall) anchors / plugs a few years ago and think they are fantastic. They are ridiculously easy to use and are extremely effective in attaching fixtures to walls. One of the main things to be aware of (as with all things that have fixtures hanging from them) is the recommended maximum weight loading of each size of anchor. What ever the packet says, adhere to it.
