Draw Circuits With a Pen

by Leave a Comment

Creating basic circuits by hand is the best way to learn about how electronics work and using a breadboard has traditionally been the best way to do this, at least until now. Circuit Scribe is a kickstarter project that features a cool new ball point pen that uses a conductive silver ink which is perfect for drawing simple circuits. Utilizing just a Circuit Scribe pen, piece of paper, and a few electronic components like a LED light or a small motor, you can create just about any small project that you can imagine. This catchy idea has already pulled in $260,000, which is far beyond the set goal of $85,000.

This pen would make a great tool for children to use in the classroom to learn about simple circuits and there’s even a Classroom kit that includes 10 basic kits and a activity book. You can also buy just one basic kit for yourself to see what you can come up with. You can also get two larger kits, the Maker Kit and Developer Kit.

Each kit includes the Circuit Scribe pen which can be purchased separately for $20.

Here’s what’s in the Basic Kit (Cost $30):

  • 2 LED Boards each with two (2) LED lights attached
  • 2 Coin Batteries
  • 9V Battery Connector
  • 2 PIN which you can add Resistors, Capacitors, and Switches to
  • Slide Switch
  • Jumper Stickers
  • BJT NPN Transistor

Maker Kit ( Cost $50):

  • Includes Basic Components
  • Maker Notebook
  • RGB LED
  • Photo Sensor
  • Sound Buzzer
  • Potentiometer
  • 8 PIN ( NAND Logic Gate, 555 Timer, OP AMP)
  • Stencil
  • 9V Battery

Developer Kit ( Cost $100):

  • 2 Basic Component Kits
  • Maker Notebook
  • 2 Sets of Maker Components and Developer Components
  • 10 Magnetic Connection Cords
  • USB Micro B Power Adapter
  • Motor
  • 2 DPDT Switches
  • 10 DIY Solder Boards

How To Make an LED Cube

by Leave a Comment

This is a great build video for an 8x8x8 LED cube by Kevin Darrah that I stumbled upon on the web. It goes over the basic build techniques  and shows you how to utilize a jig for assembling the LED arrays. As you watch the video you will quickly begin to realize that this project is not for the entry-level builder, clearly this is something that will consume a lot of your time and patience but the end result is awesome. Either way, it’s interesting to see how it all comes together.Blue LED in a cube

There are many Arduino builds out there that can be great for beginners. If you’re not familiar with Arduino then I highly recommend that you read this introduction to Arduino, it covers everything you will need to get up-to-speed on what it’s all about.

You can find many projects in the Arduino Playground, they include schematics and code to help you build cool stuff. If you want to make a much more novice-friendly 3×3 LED Cube you can use these schematics and code.

So what are you waiting for? Find a project and get building!

 

The Inspirational Fun of DIY Electronics

by Leave a Comment

From making your own radio to creating your new robot best friend, do it yourself electronics are just plain fun. Sensors, capacitors, diodes, motors,L.E.Ds, and many other components can all be tied together using either a breadboard or a piece of wood and some screws, all to create something awesome with your own two hands. DIY electronics not only can be rewarding and fun but can also get your mind thinking in a “engineering mode”.  When you gain a deeper understanding of how electronics are put together, you can begin to imagine putting something together that maybe someone else hasn’t.DIY electronics on breadboard

There are a few different ways that you can begin building electronics but if you are just starting out you may want to pick up a hobby or project kit. You can purchase labs with snap circuits or you can jump right into it and grab a breadboard and look up some schematics. Electronic kits are available from many different vendors online and a simple google search will most likely get you where you need to be. Radio Shack of course still offers many kits online as well as in store.

Robot kits are one of my favorite ways to build.  From solar powered grasshoppers to robotic mini-tanks, your options seem endless. Many robot kits will even allow you to use programming language to set up how your robot functions.

DIY electronics are also a great way to challenge the minds of your children. I remember my father bringing home one of these kits when I was just a kid and I spent many summers working on all of the projects in the book. When I finally reached the last page of the particular project I was working on and flipped the switch, it was awesome to see it all come together. It was such a great feeling to know that I put it together myself and it works!

If you get really good you may even be able to repair some of your stuff. Remote stop working? Television on the fritz? Maybe even repair that old iPod you have laying around. Heck, knowing what you’re doing can save you money in repairs. Just remember that opening up and attempting to repair home electronics usually voids the warranty, so only do this if you are really sure of what you are doing or if you don’t care about what you’re trying to fix. As always be sure to practice safety when working with electronics and use common sense. Always make sure that the power source is disconnected before beginning any work.

Tools play an important role in working with electronics and you should look into buying an electronics tool kit that usually includes things like the following.

  • 5 pc file set
  • PLCC extractor
  • 3 pc soldering aid set
  • 6″ tweezer
  • Brush
  • 6 pc precision screwdrivers
  • Screwdriver handle w/drivers bits
  • IC extractor
  • Mini-flashlight
  • Utility knife
  • Anti-static strap
  • Soldering iron
  • 7-in-1 tool
  • Mini-hammer set
  • 3 pc soft screwdrivers
  • 7 pc folding hex key set
  • 3 prong holder tool
  • 5″ cutters
  • 6″ adjustable wrench
  • 5″ long-nosed pliers
  • 8″lineman’s pliers
  • 4.5″ flat-nosed pliers
  • 4.5″ bent-nosed pliers
  • De soldering pump
  • Solder core
  • Heat sink
