Planet Arduino

Have you ever wanted to build your own Arduino from scratch? [Pratik Makwana] shares the entire process of designing, building and flashing an Arduino Nano clone. This is not an entry-level project and requires some knowledge of soldering to succeed with such small components, but it is highly rewarding to make. Although it’s a cheap build, it’s probably cheaper to just buy a Nano. That’s not the point.

The goal here and the interesting part of the project is that you can follow the entire process of making the board. You can use the knowledge to design your own board, your own variant or even a completely different project.

[Pratik Makwana] starts by showing how to design the circuit schematic diagram in an EDA tool (Eagle) and the corresponding PCB layout design. He then uses the toner transfer method and a laminator to imprint the circuit into the copper board for later etching and drilling. The challenging soldering process is not detailed, if you need some help soldering SMD sized components we covered some different processes before, from a toaster oven to a drag soldering process with Kapton tape.

Last but not least, the bootloader firmware. This was done using an Arduino UNO working as master and the newly created the Arduino Nano clone as target. After that you’re set to go. To run an actual sketch, just use your standard USB to UART converter to burn it and proceed as usual.

Voilá, from zero to Nano:

If you still want to build an Arduino but the difficulty level is a bit high for you, maybe a good idea is to start with the Shrimp.

Next to our Arduino booth at Makerfaire Bay Area we had a cool project created by Antipodes, a girls robotics team headquartered in Pacifica, California, USA. It’s a Do It Yourself (DIY) remote controlled (RC) model maglev with electromagnetic propulsion, or shortly called maglev.

A maglev is just like a conventional train but instead of wheels it has magnets and it levitates!

The team did a great job not only for the results achieved but especially in sharing the project’s documentation, detailed with all the steps for the construction through videos and pictures so that others can more easily follow in their footsteps.

The maglev, which won the Maker Faire Editor’s Choice blue ribbon,  contains Arduino UNO, Arduino  Wireless Protoshield, plus many other components you can explore in their videos below and in the project page.
