Many years ago, I was considering myself as a specialist of Makefiles … But now, I know that Makefile science is not like bicycle and you may loose all this knowledge as soon as you start to java Code …
So I’ve to go back to Makefile school again and here are some of my googling notes on this topic for my own remembers and why not yours !
The last step to use a ATMega328P / Yabbas from the Arduino IDE is to plug it with a FTDI cable (TTL RS232 over USB). Personnally, I’m using the TTL-232R-3V3 to do it. The first step was to create an adaptor to transform this cable output to the YABBAS pinout.
Recently I made a Yabbas arduino system ; this is a low cost arduino (7€) you can DIY. I’ve made it with a group of people from my city (look here) and my daughter. During this session we have finished the prototype but not had the time to flash the AtMega328P.
Now this is done using my Arduino Leonardo as an ISP programmer. I’ll detail the way I’ve done it here
I recently created a printed circuit board for a raspberry PI design i’m working on. By the past, when I did such things, the cost to make it was not accessible for a home made design. In 10 years things have change a lot and now, you can do it for less than 100€ for a 10×10 two layer board. 4 layer is also something accessible.
I want to share with you this experience, because, I had a good and an bad experience to share.
You can imagine a lot of use cases for a such thing : a pen able to create electrical conductivity over ink. The one I found really interesting this morning is to make electronic a fun activity for my daughter. That’s the reason why I backed on this product.
This is a kickstarter project accessible for a couple of euros. I let you have a look to the project itself here .
Galileo is an Intel platform compatible with arduino ; more of that it is an embedded Pentium class platform. With 400MHz and 800mA and 55€ with Ethernet but no video out, I’m not totally sure this platform provides a real new thing in the embedded world.
By the way, it have some interesting advantages :
I let you have your own advice, to take a look to the detailed description here and buy it here (actually 9w delay)
After mixing different source of information, I was able to decode some Oregon Scientific sensors to get Temperature and Humidity indication, over the air, on 433.92MHz, with a Raspberry PI system. This article gives some details of this adventure …
You follow this implementation at your own risk…
If you are interrested in this article, you could also take a look here where you can find a RF433 shield and the associated code
After having test some receiver, naturally, I’ve tested some transmitters, the objective is the same : get the best coverage in the same condition : I would say poor conditions. Lots of wires going every where and an antenna make with a simple 17.3cm wire. As expected, results vary regarding the emitter used. Reed more to get details.
