New SDuino variant. I would call it "SDuino-Qi", wireless power transfer system embedded SDuino! Details can be found in daily log!
Now SDuino is on your wrist
Details can be found in daily log. Please check it....
I would proudly present, my ultimate SDuino,
SDuino with SAMD21G18A ARM processor. Here comes new generation of SDuino!
Please see additional information at daily log..!
Thank you everyone, and I am so glad my SDuino project is selected as "semifinalist of Hackaday Prize"!!! I made a short summary video of SDuino! Have fun!!
**** Please also check "daily log" below ****
And finally SDuino has an embedded graphic display.
Details can be found at daily log!
Now SDuino can measure pressure, temperature, and humidity. By measuring these values, SDuino will show the current temperature-humidity index, which is quite important to avoid heatstroke, the fatal disease in summer season!! (In Japan, hundreds suffers and a lot of people are dead, even well-organised 21st century!)
Once I was excited to see Intel's announce that they will release "SD card sized (SD card shaped) computer", but it was not true. This time I made a real SD card sized full programmable (indeed, Arduino pro compatible) small computer board!
It consists of ATMega328P and four LEDs connected to D6 to D9. (red, blue, green, white).
As shown in above image, I assigned several non-standard function to SD card interface, but I needed to be careful for VCC and GND, not to make short circuit even if my wife puts it to computer by mistake. A0 is assigned to one of GND, which will not make fatal side-effect for computer connection.
Detailed operation can be found in the following movie...
And now I made very smart SDuino writer! Details can be found in the daily log!
actual operation can be found in the following movie. Have fun!
.... actually I had an ambition to make self-powered (battery inside) SDuino, but smallest with enough current-out battery was 50mAh Lipo , which has more than 2mm thickness... Dammit!
(manganese dioxide has smaller one, but it can provide very small current around 0.5 mA...)
And now SDuino has pressure sensor init!
and now it can play music!!!!
