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 models. Here’s how the latest SuperFunky looks (note the added micro USB port) Page views:…

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, I managed to squeeze in a voltage regulator, while keeping the step-up circuit. Another change that I…

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 anyone will rarely use, for example the SD card option, the voltage divider or the…

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 depends on the VCC and temperature. You can measure both in the code and adjust…

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 install PEAR email. So I modified emoncms to use the in-built emailing rather than third…

‘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 – this is the Funky sensor less the voltage step-up circuit. Useful when you will…

Hooking my wireless doorbell to the Internet

Here is a fun project: hook my wireless doorbell to the Internet and get SMS when someone rings it. Useful when I am not at home or am in the backyard and can’t hear it, but I carry my mobile phone with me. My wireless doorbell is some cheap model that Google doesn’t even find,…

Solar Funky

I thought it would be a nice experiment to put the Funky in a solar-powered garden lamp. I got one recently with the intention to use it for that particular experiment, it is quite cheap, costs a little over one euro. Inside we have a rechargeable battery of unknown type. I’d assume it is NiMH, it is size…

Getting Funky

Catchy title, right? I ordered some Funky Sensor PCBs after few days ago and got them today. Just to recap – this is an extremely small Attiny84 based sensor with RFM12B module on top. I can’t stress how small it is, it is just slightly larger than the RFM12B board. My version is different from…
