Back us on KickStarter!

The MegaCube, controlling a robot arm.

About

MEGADOM Electronics Inc. is comprised of three individuals: Mike, Jon and John.

Mike Dombrowski Mike Dombrowski has a Bachelor of Science in Electrical Engineering Technology, and is the creator of the MegaCube. Mike's extensive background in electrical engineering has given him a deep insight into the needs of the prototyping community and yes, he has designed many things, some of which he could tell you about but then he'd have to kill you.

Jon Havrilesko Jon Havrilesko, Professional Engineer (P.E.) has a Masters of Science in Engineering, SEMM and a Masters of Architecture from U.C. Berkeley. Jon has been acknowledged with numerous design awards and is the head of our business organization.

John Tolle John Tolle
has an Electrical Engineering Technology degree, but he's really more of an online marketing guy. He is useful in the ways of organization, art and web design and all around motivation.

Just about everything has an Arduino in it these days. This includes everything from 3D printers to remote control vehicles to lighting systems. Its biggest user base, of course, is engineers who use it to develop new electronic products.

Mike is always building circuits using Arduinos for rapid prototyping and little projects. He created the MegaCube out of necessity when he found himself constantly making adapters to fit the original Arduino Mega into his projects. His early prototypes were built on a TQFP100 breakout board and needed extra parts to function, so he created the MegaCube to be a standalone Arduino.

MegaCube Prototypes
The various stages of MegaCube evolution

Soon, we will be a giant corporation with all kinds of wicked products (with your help, of course) but for now, we a humble company that is proud to present the MegaCube and its accessories!

Products

The MEGADOM product line is a tight knit group of awesome devices, lead by the MegaCube.

The MegaCube

The premier enhanced electronics prototyping platform.

Why it's better

  • Store multiple programs on the MegaCube simuntaneously to seamlessly move between eBOSS-enabled projects
  • Smaller than the original Arduino Mega and most other Mega clones
  • "Socket-able" to allow easy reuse (see eBOSS below)
  • Access all 100 pins of the ATMEGA 2560 processor using Atmel Studio
  • Doesn't require proprietary connectors, just an FTDI cable or ICSP programmer
  • Uses standard 0.1" pitch spacing to make it Protoboard friendly
  • More reasonably priced than the original and most other clones
At 1.8" x 2.1", the MegaCube is only about
four times the size of a U.S. Quarter.

The eBOSS

Plug in the MegaCube and use it over and over - no solder required.

What it's good for

The Embedded Break Out Shield System (we call it The eBOSS) adapter allows you to solder the adapter instead of the MegaCube itself. This makes it easy to reuse the MegaCube in other projects or downstream prototypes.

With the Unique ID chip on each eBOSS, the MegaCube can house multiple programs simultaneously and automatically execute the right one when plugged into different projects, without needing a computer to swap sketches in-between!

Features

  • Unique ID chip includes...
    • a 64-bit registration number
    • a 48-bit node address
    • programmable bits so you can add your own personal ID/data
  • Size: 2.9" x 2.6" (7.4 x 6.6 cm)
  • Breaks out all 100 pins of the MegaCube to PTH headers
  • 1 x Atmel In Circuit System Programmer connector (ICSP)
  • 3 x Symmetrical 0.25" mounting holes
  • 1 x Breakout for a barrel jack for raw input power

Coming Soon

Example code that will show how easy it is to use the Unique ID feature across several eBOSSes to automatically execute the right sketch among many stored on a MegaCube.

MegaCube Questions

1. How do you load programs onto the MegaCube?

The MegaCube comes preloaded with the Arduino Bootloader so the easiest way is to use the Arduino Environment and an FTDI breakout board or FTDI cable. There are other alternatives to program the MegaCube such as Atmel Studio 6.2 and the Eclipse CDT with the Arduino plug-in.

2. What voltages are supported by the MegaCube?

Currently only 5V TTL and 0-5V analog in is supported. There are plans for a 3.3V version which we will produce if there is enough demand for it.

3. What is the memory capacity of the MegaCube?

The MegaCube is based on the Atmel Atmega2560 IC. It has 256k of program space on board.

4. What is the clock speed of the MegaCube and can it be modified?

The MegaCube comes clocked at 16Mhz. One of the biggest benefits of the MegaCube is that the Clock pins are broken out so external clocking is a breeze. The frequency of the IC can be changed by removing the on-board crystal and using the broken-out clock pins.

5. How do you access all 100 pins on the MegaCube?

The Arduino environment currently does not support all 100 pins of the MegaCube so to get full advantage of the ATmega2560 chip we recommend using Atmel Studio which gives unprecedented control and debugging of the MegaCube.

6. Can you use the MegaCube as an Arduino?

Yes, the MegaCube comes preloaded with the Arduino bootloader. It works similarly to the standard Arduino Mega, with a different footprint, of course.

7. How big is the MegaCube?

The MegaCube is 1.8" x 2.1". It's smaller than any other Arduino Mega we could find in mass production. It's even smaller than an Arduino Uno.

8. What does Proto board-friendly mean?

Proto board, Vector board and other variations are pre-made circuit boards used for permanent prototyping of a project without the cost associated with producing a custom made circuit board. The most popular proto board spacing is 0.1" (2.54mm) pitch, which is what we modeled the pin out of the MegaCube after.

9. What can I do with the MegaCube?

The MegaCube is a Microprocessor development board based on the Arduino Open Source platform. You can use a MegaCube to run a robot, a 3D printer, a CNC machine, or anything that you can think of. We'd love to hear what you plan on doing with the MegaCube.

10. Will it blend?

We hope not, but something tells us that if a cell phone will blend, so will the MegaCube. (We're not affiliated with Blendtec®, but we think their commercials are amusing.)

11. Why is the sky blue?

The sky is blue due to the gasses in the atmosphere that absorb most visible light excluding the blues you see. Some like to say that it's a reflection of the color of the ocean, which is inaccurate.

12. Are angels bowling when it thunders during a storm?

Heavenly bowling alleys do not tend to share that data. What we do know is that the sound is caused by lightning strikes which cause a very fast vacuum to be formed and the crack you hear is when that column of emptiness is very quickly filled up with air once again. Or something like that.

13. Will you be putting up some additional FAQs instead of explaining how the atmosphere works?

Yes. Soon. Very soon. You have no idea how soon. Like, right after the next time you refresh this page. Well, you know, we mean once you've given up refreshing, if you would have only refreshed one more time, you would have seen some more new FAQs. Really. Seriously, we'll have more good stuff up all the time.
