Turn Your Old Router Into A Range-Boosting Wi-Fi Repeater. If you’re upgrading to a faster, stronger wireless router, don’t chuck your older Wi-Fi box.

Turn Your Old Router Into A Range-Boosting Wi-Fi Repeater

With the magic of DD-WRT, you can turn your older wireless router into a range-expanding Wi-Fi repeater to cover everywhere you need a connection. The advent of wireless home networks grew slowly in the past decade, but reached the point at which nearly every home with a high-speed connection had a wireless router that shared Wi-Fi connections throughout the home. Now Wireless N has become the standard at electronics retailers, promising faster connectivity with your wireless devices, faster transfer and streaming speeds between devices, and better connectivity.

So what’s to be done with your home’s first wireless router? MSGEQ7 Graphic Equalizer Kit - Rheingold HeavyRheingold Heavy. This is a kit to build a breakout board for the MSGEQ7 Graphic Equalizer chip.

Using this chip, you can take any audio input from a standard 3.5mm stereo jack and read the levels of seven frequency bands. 63Hz160Hz400Hz1kHz2.5kHz6.25kHz16kHz The level is read as a voltage level from 0 to VCC on the OUT pin of the board. Frequencies are cycled through by applying a 0-VCCsignal to the strobe pin. You can use those frequency levels to adjust other things like dancing LEDs! The kit includes the printed circuit board, the master MSGEQ7 chip, a breadboard compatible pin header, three resistors, four capacitors and the stereo input jack.

How to Set Up Your Own Remote Home Monitoring System. Ever wish you could use your tech to keep an eye on your home while you're gone?

How to Set Up Your Own Remote Home Monitoring System

Well, you can--and you don’t need an expensive, dedicated setup. All you need is a webcam. In this how-to package, we'll show you how to use your everyday tech to set up a motion-detecting camera in your house, so you can keep an eye out for intruders, mischievous pets, or even roommates with a weakness for the contents of your snack drawer. First, we'll use Yawcam software to employ any standard PC webcam (USB or built-in) as a surveillance camera for free, so you can keep an eye on your home desk for yourself. Gears, Pulleys, Belts & Chains. Transistor Tester. Theory With all the circuits I make, I end up with a lot of circuits hanging about. Not many of my projects are permanently used, their parts being recycled into new projects.

Even fewer achieve the final accolade, "box status", so it is a measure of how pleased I was with the design that this project was instantly built into a box with its own interfacing circuit. So let's see what we need to do to build an intelligent transistor tester. First off, remember that we think of electricity flowing from the positive terminal to the negative one, whereas it is actually a flow of electrons the other way round. Transistors nowadays, are mainly made using silicon, initially germanium was used but is seldom found now.

Now these positive particles are called holes and don't really exist. Well having got that concept I can describe a transistor and how it works. Ultimate Tic-Tac-Toe. Updated 7/16/2013 – See Original Here Once at a picnic, I saw mathematicians crowding around the last game I would have expected: Tic-tac-toe.

Ultimate Tic-Tac-Toe

As you may have discovered yourself, tic-tac-toe is terminally dull. There’s no room for creativity or insight. Good players always tie. Games inevitably go something like this: But the mathematicians at the picnic played a more sophisticated version. As I watched, the basic rules emerged quickly. Each turn, you mark one of the small squares. But it took a while for the most important rule in the game to dawn on me: You don’t get to pick which of the nine boards to play on. Then your next move must be here… This lends the game a strategic element. The resulting scenarios look bizarre. This to That (Glue Advice) Snackbot - The Internet Connected Candy Machine. Step 1: Parts & Supplies To complete this project, you are going to need the following: • 1 x Brookstone SnackMan™ • 1 x Part Bundle (includes 1 each of Electric Imp Card, April Breakout Board, NFET, Diode, 10KΩ (or higher) resistor) You are also going to need some tools: • Philips Screwdriver • Soldering Iron • Solder • Foam Tape (or other adhesive) • An iPhone or Android Phone Step 2: Disassembly The first thing we need to do is disassemble the SnackMan.

We're going to take out (almost) all of the electronics, and replace them with an April board, and the NFET. Disassemble the SnackMan: 1. You should now have 5 pieces: 1. We won't be using the main board or the IR board; these can be thrown away (or kept for future projects). Step 3: Hacking the Switch The SnackMan has a dial to turn the machine on and off, as well as control the serving size. Here's what we need to do: 1.
