I have created a TinySensor Wiki, it is available from the top menu and this link. I will be extending it as time permits.     Page views: 1483

TinySensor 1.4 PCB is ready

I now have the TinySensor v1.4 in my hands, there are some small improvements over the version I last published, most notably that I added a 3.3V FTDI connector. You can’t use it to program the Attiny (..yet, I am working on that too), but it provides serial debug connectivity plus power source. Quite handy…

DIY soil moisture sensor project

I have been working on a small DIY soil moisture sensor project the last couple days, mostly inspired by the gardenbot project. The idea is to add it to my greenhouse monitoring project. I chose to make my own sensor because it is quite easy to do, but if you prefer to buy a readily…

TinySensor v1.4 plans

I have been working to upgrade the TinySensor v1.3 to a new version these days, that addresses the issues I had identified so far. I am keeping it in through-hole components for easy soldering and also so that one can easily use different configurations by soldering/de-soldering certain components. PCB size is unchanged (38x56mm),   Here are…

RFM12b to serial PCB for my Pi

[edit] This board is now available for sale in my store Here is a little project that I worked on last weekend: A small home-made PCB to permanently fit the RFM12b-to-Serial on my Raspberry Pi. Although I am aware of at least couple on-going efforts to have native SPI support for the RFM12b, these are relatively…

Stamp sized ATtiny84 remote sensor

I have been amazed by the work done by @Tobias with his “Funky” sensor, so I asked him for a permission to make my own version. The Funky is a JeeNode micro clone, less the two Jeeports and probably in 1/3 of the size. Basically it is the size of a mail stamp measuring just…

Using ATtiny 84’s internal temperature sensor

I have always wanted to test the internal temperature sensor that the ATtiny84 has. I think it is quite nice for a really low power node since no external hardware is required. I googled for some time and found a nice example, but for ATtiny85, that MCU has different registers to poke before accesing the…
