Since this morning, myTeepi project has been launched on the Ulule crowdfounding platform. This solution is a smart way to care of your distant house, it works in a context with NO internet, NO phone … No power supply ! Yes it is !
The Tobeca 2 is a French and Open Source 3dPrinter. THis printer is delivered in a kit (you can also ask to get it built for a higher price) The price of the printer is about 700€ + 100€ for the dual head option I chosen.
So I’ll publish some post in the next days to detail the installation. My time is really short these week, so it could be long before I finish it. By-the-way if you have one to build of you want to buy one, I hope these notes based on my experience will help you.
Finally, I spent about 16 hours to mount the printer and a couple more to get my first print!
The TD1205 device is more than the usual Telecom Design Sigfox embedded circuit as TD1204 and TD1208, they are a all in one chip providing GPS antenna and RF antenna. Ready to use, to be clear you just need to plug a battery to use it.
In my point of view, for many applications not requiring more than 2 GPIOs, this product is really easy and chip way to design a SigFox product. As it costs around 55$ and you just have to add box & battery id sounds like the most affordable for small quantities. But …
This post is detailing what is specific to this chip ; read more following the link
I assume you know a little bit who I am and what I’m doing, I’m not the one to by > 100€ to buy a one shot development board kit to test & hack a device like the Telecom Design chip. So basically I built my own with the objective to work with multiple configuration.
My “cahier des charges” was to make a board able to be installed as a dauther board on a raspberry PI, able to support an arduino, able to run autonomously and being able to own a TD1204 as a TD1208.
It was a huge work to route it and I must recognize that it do not have all the GPIO connected as I expected but it exists, it works and it help me to build my first SigFox prototypes with success.
So, now, I propose to distribute this board to those of you looking for a such swiss knife.
