Build an 8-Bit Heart with MeowCAD


You can find some interesting projects on MeowCAD and one of these is a“8 Bit Heart”. MeowCAD is an online, in-browser electronics design tool that’s completely free and open source. Use it to create schematics, printed circuit boards, share with your friends or just play around.

At some point, after you design your schematics and boards, you want to submit them to be fabricated. Whether you use MeowCAD or some other tool, the workflow is pretty similar. We live in a pretty amazing time where this can be done for reasonable cost with only a few weeks delay.

iPhone schematics and more…

Random Stories from China @ bunnie’s blog – [via]

Yep, that’s right, the book of iPhone schematics. I snapped that baby up for $4. My feeling is that these schematics probably come from leaks of original Apple sources, because many of the annotations couldn’t be divined from a clean-room reverse engineering job. For example, the above schematics annotate that the AP_UART connection on the dock has a dual-footprint option for a possible drop-in DisplayPort upgrade. Anyways, these schematics are useful as a sourcing guide for cheap components. Any part found in this book has been made in millions-per-week quantities, which is a handy fact to keep in mind when bargain hunting for stable supplies of cheap components.

Circuitbee: Sharing Electronic schematics online

Circuitbee: Sharing Electronic schematics online [via] .. Ben Delarre shared his story with Make about the origins and future of Circuitbee, a service that allows you to embed schematics on websites…

Have you ever designed an electronic schematic then wanted to share it on your blog? Or wanted help improving your circuit on a forum? Ever peered at a tiny/massive image of a circuit on a website and wondered why on earth there wasn’t a better alternative?

We have. Back in 2010 we were working on our first major electronics project, the Illuminatrix, an array of 256 RGB LEDs that were to show animations created by people all over the world at the Burning Man festival. It involved using a lot of technology we’d never used before, so we weren’t quite sure about our circuit designs.

We tried posting on blogs and forums trying to explain our schematic and the problems we were having with it. This proved more difficult than we expected: describing a circuit in words is really hard, so we tried to post an image of our schematic instead, and our schematic project files.

This involved a lot of messing around with capturing JPEGs of the schematic and uploading all the project’s symbol libraries and schematic files. But of course people willing to help didn’t necessarily have the right software, or the JPEG was too small to read usefully, or too large to post on many of the forums. We thought that there must be a better way to share schematics, to discuss them, and to show them to people while writing about them. It turned out there wasn’t anything out there that would help us do this, so being the ambitious fools that we are we set out to create it.

CircuitBee is like YouTube for your circuit schematics. You upload your Eagle or KiCAD schematics, we crunch the numbers and create an online embeddable version of your schematic. You can pan and zoom, and mouse over components in your circuits for more details .

We’re still at an early alpha stage right now, so you’ll have to forgive any hiccups we have going forward. But you can get started immediately by visiting Circuitbee and signing up for an account. Then simply upload your schematic files, any associated library files, and let our servers do the hard work. Within a few minutes your schematic should be ready to embed on your site or forum.

Eventually we plan to add lots more useful features like downloading original schematic files, searching for components within schematics and adding notes and annotations to your circuits. We want to make it easier for all of us to communicate our circuit design ideas and to help each other improve our designs.

We hope to make CircuitBee into the most useful service for hobby electronics enthusiasts, so we’re going to keep the service free for as long as we can. We’ll need your help to reach our goals though, so please let us know what you think of the site, what needs improving and what else we can do to make learning about electronics and sharing your designs easier than ever before

Find schematics, wiring diagrams, etc. for everyday electronic devices

siliconghost writes:

If you’ve ever found yourself taking apart various electronics to build something of your own, this Instructable is for you.

Sometimes it might be handy to have more detail on the inner workings of the device. Wouldn’t it be nice if you could get the full schematics, interior photos, and other technical detail before you even pick up a screwdriver? Well you may be able to!

Compact Fluorescent Lamp (CFL) schematics

Compact fluorescent lamps have some benefits in comparison with classic light bulbs. It is lower power consumption (to 80%) and much longer lifetime (5 to 15 times). Disadvantages are longer starts mainly at more expensive types, impossibility to use darker and price.

Schematics representing Chaos theory


What is Chaos theory? Chaos theory is the theory that describes systems that appear disordered, but also this theory is about finding underlying order in apparently random data. According to Wikipedia:

Chaos theory describes the behavior of certain nonlinear dynamical systems that may exhibit dynamics that are highly sensitive to initial conditions (popularly referred to as the butterfly effect). As a result of this sensitivity, the behavior of chaotic systems appears to be random.

Surpisingly, chaotic effects appear on systems that are deterministic, that means it appears on systems without random elements involved. According to another definition:

A chaotic system is one where the system’s variable quantities satisfy deterministic mathematical equations (i. e., present values may be calculated from past ones), while at the same time being highly irregular, but still contained within a finite region (the “strange attractor”).

Did you know that chaos can be represented using simple electronic circuits and appear on your oscilloscope’ s screen? A circuit that can differentiate a voltage is able to represent the differential equations describing a chaotic system thus appear “attractors” on your oscilloscope. On the site bellow you will find some simple chaos-generating electronic circuits that will “blow your scope”!!
