Office Door Knocker Castle

We are always looking for more ways to make our office fun and strange. One of our engineers, Mike, until recently rigged elevator Tardis sound and play. I wanted to do something similar in my office, but, especially. I often close my door does not work, but most of the time, when someone comes to my office, the door to indicate their presence in the rap formal announcement. I decided to have a little fun with him.

Using the TTS256 with the Voicebox Shield

What are we doing?

IC is a cool little text to speech TTS256 SpeakJet IC chip that is connected to the device and the user text automatically send a text string and sounds are converted to be able to interpret SpeakJet. You can send TTS256 English words aloud and then Speakjet essence of the word; How cool is that! A person of this ourselves,

Learn How to Solder: BigTime Quickstart and Council Directive

Getting started

Learn how to solder: BigTime Watch Kit is an all-in-one kit helps you go from noob Welding Welding guru. It is when you have all the ingredients and equipment you when you're finished, you skills you can use to create even more toys, kit to assemble, and service. In this guide, we have included in your kit is a quick rundown of all the items will talk briefly about each one, and then show you how to put it all together.

Necessity:

BigTime Quickstart and Council Directive

The kit used by people who have never in their lives pick up a soldering iron is designed to be, and it is these who want to brush up on their skills in welding can be used by design. So, no matter your skill level or age, Learn how to solder: Big Time can be fun for all walks of life.

Before we get in the building, let's make sure we have everything we need. Are you following all the kit should include:

• Soldering iron
• Soldering iron stand
• Lead-free solder - 10 g Tube
• Flush Cutters
• Solder Wick
• SparkFun Safety Glasses
• BigTime Kit

You'll notice that there is a small box inside another box. In this box, you will find all the parts for BigTime Kit Watch. This kit includes:

• 1 X pre-programmed IC dip ATMega328
• 1 X 4 address 7 segment display
• 1 X 32 kHz, Crystal
• 1 X 10 ohm resistor
• 2 x 0.1uF capacitor
• 1 X right angle tactile buttons
• 1 X 20mm coin cell battery holders
• 1 X 20mm coin cell battery
• 4 x 4-40 screws
• 1 X Allen Wrench
• 1 X Velcro Watch Bands
• Parts acrylic enclosure
• Council Directive

If any part is missing? Sometimes it can get a little misplaced one element. If you've been wanting to contact our customer service team, and we will share in a snap.

Rally

Instead, try and talk you through the assembly process, our friend David Stillman, we'll show you how to build BigTime being offered in the following video.

Conclusion

With that, you have a fully functional BigTime Watch your friends and family must be ready to show off. If you have any questions or comments, please drop them in the box below. Happy soldering!

ProtoSnap - E-Sewing Kit Getting Started Guide

To add a little zest to your wearables you're looking for, it's bright, white LEDs do not get more delicious. But, if you're new to e-textiles game, really general electronics, cable (or sewing) can seem like a daunting task in a deliciously thought circuit. E-sewing kit ProtoSnap our more basic, yet useful, some of the concepts taught in the circuit is aimed at, so you confidently of anything you fancy LED, switches, buttons, and the battery can throw.

VoiceBox Shield Quickstart Guide

"Hello World" never sounded so good

Voice Box Shield is a unique element to your Arduino- compatible system allows a robotic voice. It's a SpeakJet speech-synthesizer chip and an audio amplifier that can directly drive consists of a small speaker. In addition to forming the speech commands sent to it, SpeakJet tones and other chips, such as "robot" noises There are many other features such as the ability to coordinate. It is pre-stored phrases that can be set up when the input pin is triggered. Detailed technical information, see the User Guide SpeakJet.

Robot Claw Tutorial

Short Description

Assembly and robotic claw, and questions about the suitability of the medium server after receiving a decent amount, a small tutorial, I decided to write about assembling claw. We are getting your claw and grab it as quickly as possible to go over the basics.

LED Current Limiting Resistor

An LED current limiting is very important. Preventing an LED circuit will behave very differently. Ohm resistors to behave appropriately in accordance with the law: V = IR. For example, an increase in the voltage across the resistor, the current proportion is the same as the value of the resistor will be increased. Simple enough. LEDs do not behave in this way. They are a characteristic V curve that I'm different than a resistor, such as a diode behavior.

The FCC and Open Source Hardware

Electromagnetic Spectrum: the United States, the FCC tried to use the same resources to hundreds or thousands of businesses are responsible for maintaining harmony within. The upside to this is that we can (usually) things like WiFi, cellular phones, police radio, baby monitors, etc. depend to act as and when we need them. The downside is that each of us to do business in the United States who want to sell electronics and electronic devices creates a hurdle.

RC Hobby Controllers and Arduino

Remote Control Arduino

Robots, cars, robot cars, and the sport needs some degree of remote control devices of all sorts. Most of the time, do it yourself, or some other XBee wireless technology to implement this test. Sometimes it is not a bad idea, but it is more often than not driven and somewhat frustrating way to see more from them. If you find yourself thinking, "I just put the stick RC car battery to push and move it, I remember the good old days."
