One of the things that has been bugging me recently is the power consumption of the SD card that I now have in the Tiny Sensor v1.2 design. I intend to power the sensor either via an external source (2xAA…
Toying with ATTiny84 and SD card in Arduino IDE
As I mentioned in my previous post, I tossed in a SD card port for the TinySensor v1.1. I wanted to give it a live test and see if/how it works prior to submitting the PCB to the fab house. So I…
The Tiny Sensor gets a SD card port
I had some space left on the TinySensor v1.0 PCB, plus I left myself few days to think before ordering the first batch, so I decided to throw in a SD card port. I didn’t want it to be anything…
Tiny Sensor plans
I have been working this weekend on improved version of the ATTiny84 remote sensor, this time I will use a PCB fab house to make at least 15 pcs of the PCB. The improvements over the old hand-made PCB are:…
Single sided ATtiny84 temperature sensor PCB
Following the fiasco with the first version of the PCB, I have decided to create a single sided PCB so that the DIP socket that was causing me trouble is on the top. Here are the results, the PCB works…
