Coffee, bits and bikes: We're back..
http://bitsnbikes.blogspot.com/2014/03/were-back.html
Coffee, bits and bikes. My projects in the world of electronics, computers, bicycles and coffee drinking. I've been busy (very), but I'm still here. Starting the first post of the year on the end of March is not the best indication of a success blog (which I don't have). but I'll try to post some old stuff that I did meanwhile. I've lost a bit of touch with the Arduino and last time I check things have gone mainstream and big (check this one out, an ARM Arduino. Meanwhile I've started with the RaspberryPi.

Coffee, bits and bikes: AVRStudio 6.1 and Code Composer Studio 5.4
http://bitsnbikes.blogspot.com/2013/08/avrstudio-61-and-code-compeser-studio-54.html
Coffee, bits and bikes. My projects in the world of electronics, computers, bicycles and coffee drinking. AVRStudio 6.1 and Code Composer Studio 5.4. A new second hand laptop. And a new windows XP re-install and all the tools for micro-controller development. If you are looking for a comparison between the above tools stop reading. * * This is a public bashing of both tools, they are s# t * *. I recently bought some MSP430 development tools. It has the following problems:. I thought that was horrible, bu...

Coffee, bits and bikes: HF on the ATtiny15
http://bitsnbikes.blogspot.com/2013/03/hf-on-attiny15.html
Coffee, bits and bikes. My projects in the world of electronics, computers, bicycles and coffee drinking. HF on the ATtiny15. I wanted my class E amplifier. To be driven by an Attiny15. The idea is to build a HF (6.78MHz) low voltage and low power beacon. The maximum PWM frequency attainable using the factory OSCCAL value, and using OCR1B=2 and OCR1A=1 is 8.525MHz with the only possible duty cycle is 33%. With OCR1B=3 we get 6.393MHz, OCR1B=4 we get 5.115MHz. A NOP consumes less current that an rjmp 0, n...

Coffee, bits and bikes. My projects in the world of electronics, computers, bicycles and coffee drinking. Sorry all, we've been on Holidays and now we're back. I have a couple of projects going on but one is "secret" and the other is. trash. I'm trying to make art. Or making less valuable trash out of more valuable trash). Is something for my loved one (that's why it is secret), the trash. And this one doesn't count, I promise! Now I can't get used to the new one. it was my. Precious. I got a " cheap.

Coffee, bits and bikes: September 2011
http://bitsnbikes.blogspot.com/2011_09_01_archive.html
Coffee, bits and bikes. My projects in the world of electronics, computers, bicycles and coffee drinking. I wanted to build a night-lamp for Luísa, something a bit less "spooky" than a blue IKEA Spöka. That she has. I also wanted to be able to charge just by placing it in the sun (even there isn't much of that up here). The idea of the project is that when night falls (or lights out) the light goes on for about an hour hopping from one light to the other with different ratios of fade-in and fade-out....

Coffee, bits and bikes: January 2012
http://bitsnbikes.blogspot.com/2012_01_01_archive.html
Coffee, bits and bikes. My projects in the world of electronics, computers, bicycles and coffee drinking. OpenTherm v2 First Prototype. I finaly built a prototype of the opentherm interface (version 2) for Alex. To test, since he dosen't have all the tools to test it I'm hoping that at least the physical interface works, the other features are powered through the interface and using a supercapacitor to hold the power during radio transmission. The board has a JeeNode. Posted by J Silva. Links to this post.

Coffee, bits and bikes: February 2012
http://bitsnbikes.blogspot.com/2012_02_01_archive.html
Coffee, bits and bikes. My projects in the world of electronics, computers, bicycles and coffee drinking. And now for something completely different, not only do I take an enormous amount of time to do something, I also overrun myself with different projects. After a year or so of designing PCBs and sending them for fabrication, I finally decided to go for the big one and design a full Eurocard (160x100mm) computer. I have enough confidence on my EDA package ( gEDA. I think that I am finally setting for ...
