Light up your flat with Charles’ planetary gear system

Today, we got a visitor in the Fritzing Lab: Our neighbour, Charles Oleg, came by to show us his new creation. Charles is working on a project to bring more light into his flat by using a rotating mirror system.


This system includes, besides two mirrors to reflect the sunlight, also some planetary gears driven by a 1 to 10 Watt motor. The system knows its position  via GPS signal as well as the current position of the sun and can move accordingly.

Charles showed us two of his planetary gear prototypes: one was laser-cutted and one was 3D-printed out of PLA.


He told us that those kinds of systems that track the position of the sun and move corresponding to it to receive as much sunlight as possible are currently used in solar parks  as well as in telescopes. These are large projects with huge gear-wheels, whereas Charles aims at making his lighting system affordable and open source – so that everybody can use it.

Charles scripted the gear-wheels in python and has uploaded it on GitHub. So if you want to build your own solar light system, check out his blog or his GitHub folder.


Here you can find some more pictures of the gear-wheels.

Fabulous Fab news!

We have some exciting news for our beloved fab service users!

  1. Finally you get a black silkscreen on both sides of your boards for no extra cost! PCBs with submitted  top and bottom silkscreen layers will be fabbed with both layers, as simple as that! By the way since release 0.8.0  you can flip your board in PCB view and work on the bottom layer copper and silkscreen as if you had the board in your hand.
  2. We dropped the tracked post shipping in Europe and rest of the world because it was too slow and the tracking was inefficient. Instead, you will be able to choose between UPS Standard, which is much faster, insured and trackable in real time, and UPS Express for your shipments in Europe. Customers outside of Europe will be able to choose the very affordable but untracked and slow traditional postal shipping or the 48h Express shipping service. Check out our pricing page for the new fees.
  3. We added a “Billing Address” field to your order page for the people who need to have their orders shipped to a different address than the billing address.

Happy fabbing!

We have a winner!!!

Calandria is the winner of the Fritzing Goodie Contest!

Finally, the last parts arrived today in the morning. I soldered all goodie contest finalists and tried them out.


Calandria is actually a synthesizer. Two potentiometers are influencing via a LED and light depending resistor a the outputted bird like sound. In the end the PCB size, number of components and cuteness of the product were the winning properties.

Congratulations to the other two finalists, too. Both projects are quiet amazing:

Touch my piano is sounding pretty cool, like if you would play on an old saw. It is fun and I caught myself not being able to stop. The imperial march was sounding fantastic, even if Jonathan couldn’t hear, what I was playing 😉

The Fritzing Amplifier is like a module, extending the abilities of (e.g.) the Arduino Board. It amplifies the output to drive a real 8Ohm speaker and the outputted sound has a much higher quality. If you ask me, each Arduino-Kit should contain it.

Thank you all participants for your great ideas and keep on making!

Yours sincerely,

Little Black Midi

DE: Diesen Winter hatte ich die Chance an der FH Potsdam einen Kurs in Physical Computing zu unterrichten. Thema waren Musical Interfaces und ich habe das erste Mal das großartige Teensy-Board in einem Kurs benutzt. Es hat sehr großen Spaß gemacht und die Dokumentationen treffen langsam ein. In den nächsten Wochen werde ich also die Ergebnisse hier vorstellen.

Erstes Ergebnis ist das Little Black Midi von Naomi Knopf. Hier ist die Dokumentation zu finden.

EN: This winter I had the chance to teach Physical Computing at the University of Applied Science in Potsdam. The topic was Musical Interfaces and it was a lot of fun. I used the awesome Teensy board the first time in a course. By now the documentations are done and in the next weeks I will show you the results of the students.

First project is calles «little black midi» from Naomi Knopf. Here you can find the documentation (de).

Fritzing layouted PCBs in soyus capsule

EN: Roberts project, the simulator for the soyus capsule is finally ready to test flight. Controlling PCB was created with – guess what – Fritzing!!!

You can find it at the FEZ in Berlin where children learn everything about the last frontier.

Have a great ride!

DE: Roberts Projekt, der Simulator der Sojus Kapsel ist fertig und kann getestet werden. Die Platinen wurden mit – ratet mal – Fritzing layoutet!!!

Der Simulator steht im FEZ, wo Kinder u.A. alles über die unbekannten Weiten lernen können.

Gute Reise!

Layout of the HotPi

Hardware Upgrade – HotPi

Layout of the HotPi

We all love the Raspberry Pi but some things are missing. A real time clock for example. Fritzing user Karl Lattimer just started a Kickstarter to add some cool functionality – the HotPi.

Karl is using Fritzing to document his project and our Fritzing Fab service to prototype the PCB.

The small sized PCB (56×35.4mm) is designed to sit on top of the GPIO (General Purpose Input/Output) port and provides:

– infrared receiving and transmitting
– an RGB LED to lit up in every color
– fan speed control to cool the Pi down
– the real time clock

The Kit is suited with THT (through hole technology) parts, the PCB and will be shipped as a kit.

And of course it will come with an example program to demonstrate the use and functionality, too.

To support the project go to Kickstarter: 🙂

Wir lieben den Raspbery Pi, aber ein paar Dinge vermissen wir schmerzlich. Eine echte Uhr z.B., die auch weiter tickt, wenn der Strom weg ist. Fritzing Benutzer Karl Lattimer hat gerade einen Kickstarter gestartet um den Pi um ein paar coole Features zu erweitern: HotPi.

Karl benutzt Fritzing um sein Projekt zu dokumentieren und unseren Fritzing Fab Service um Prototypen seiner Leiterplatte herzustellen.

Die kleine Platine (56×35.4mm) passt auf den GPIO (General Purpose Input/Output) Port und bietet:

– Infrarot Sende- und Empfangsmodul
– eine RGB LED
– Lüfteranschluss mit Geschwindigkeitskontrolle
– eine Echtzeit-Uhr

Das Kit zum selber löten besteht aus einfach zu montierenden THT (through hole technology) Komponenten und der Platine.

Natürlich gibt es auch ein passendes Programm zum Testen der Funktionen.

Das Projekt kann man auf Kickstarter unterstützen: 🙂

Fritzing goes into the soyuz capsule!

soyuz capsule

No, not the one supplying the ISS but one which supplies the fantasy and dreams of children here in Berlin — but step by step.

This spring, Robert came to us to buy a Fritzing Starter Kit. I asked him what he is up to do with it and he told me that he plans to build a space simulator here at the FEZ in Berlin.

The FEZ is a center for children to explore, play and interact. The people there own a soyuz capsule which should become more interactive. Wow! What a task.

Now he emailed the first pictures. He created a simulator where children have to prepare the space ship for the flight, find the international space station and perform the docking procedure.

inside the simulator, Fritzing-made PCBs in green

Robert used Fritzing to layout all the PCBs! The final version consists of the two monitors, two Arduino Megas, 26 buttons, 38 signal lights and two joysticks. The simulator software is written in C#.

Thank you very much for these awesome insights.

Awesome work! Wanna take a ride?

CNC’ing your Fritzing circuit

CNC'ing Fritzing Circuit

Our friends from FabLab Torino have created a wonderful tutorial (thanks to Federico Vanzati) on how you can prepare a Fritzing circuit for production with a CNC milling machine. It’s a relatively straightforward process using a vector software like Inkscape to convert the Fritzing DIY format to the “negative” format that the milling machine requires. The picture above shows the result. What’s nice is that they now also sourced the adequate DIY CNC machine. The Roland iModela is now available in the Arduino Store.

There have been attempts from others to mill Fritzing circuits: Checkout Don Roberts’ report, and also the tutorial from the FabLab Amersfoort (thanks to Peter Uithoven).

And then there’s still Fritzing Fab. 🙂
