As I already mentioned, I planned to have a RFM12B shield for the micro IoT gateway. Here is how it is looking, rendered in 3D, still work in progress, but the idea is clear. I wanted to keep the shield…
3D modelling of PCB designs
@Gadjet from http://www.gadjet.co.uk/ showed off some nice 3D renderings of his projects the other day in JeeLab’s forums and had me all excited about it. He used EagleUp, some nice peace of software that turns your Eagle PCB layouts into Google Sketchup…
Micro IoT gateway
I have long wanted to make my own Internet of Things gateway and I wanted it small. I have researched for quite a while on the options, and finally decided to base it on the excellent work done by Simon Küppers…
Super ‘Funky’
Tobias’s original ‘Funky’ had voltage regulator, that I removed in my version in favor of a voltage step-up circuit. How about having both on the Funky and you will decide which one to use depending on the concrete application? Well,…
Interfacing ‘Funky’ to Raspberry Pi
I am finding myself using Funkys for all of my recent projects, so I am thinking of discontinuing the TinySensor. I think the better approach would be to have various ‘shields’ for the Funky rather having hardware on board that…
Measuring humidity and temperature with DHT22 and Funky
I have been playing with DHT11 for some time, only to find out that this sensor is a bad joke. I finally decided to upgrade to the DHT22, which is a magnitude better than the previously mentioned one. I wanted to be…
Clocking ATTiny84 from RFM12B (thinking outloud)
I have been thinking on the possibilities to use external clock source for my ATTiny84 projects for some obvious reasons. Using the internal oscillator works great in most cases, but may not be so accurate in some applications (IR,RF) as it…
Updating my SMS doorbell
I have made some updates to my SMS doorbell project. Previously, I had troubles setting up the email notifications in emoncms, the problem is that I don’t have shell access to the server where I host it so I could not…
Power supply block with ADCs for power monitoring
Dave Berkeley’s recent home power monitoring blog post got me thinking: How much does a DIY power monitoring system cost How accurate it is I had a friend ask me how much my current power monitoring system costs. I really didn’t had…
‘Funky’ sensor in store
I have received permission from Tobias Floery to offer my version of the Funky Sensor in the store. I will be offering three options PCB only – for those that can do the soldering and only need the PCB “Regular” Funky…
