 Last Friday I heard some strange noises outside my office window. To my big surprise I then noticed that there was a bird’s nest growing on the window sill. It did not take long until I even saw the new tenant moving in: Outside my office window… So far I have […] Continue reading First day with BirdCam  …it arrived by mail today – and I couldn’t wait… The Wanhao Duplicator i3.  Blackboards during the last lecture in the course Electronics I. I just watched some videos and got inspired… Are Your Capacitors Installed Backwards? Capacitors 1965 US Air Force Training Film  After the first two parts of this series ATmega328P – measuring its own supply voltage ATmega328P – measuring its own supply voltage II where I investigated the possibility of the Atmel ATmega series microcontrollers to select the internal bandgap voltage VBG as input for the analog-to-digital converter. Using the analog supply voltage AVcc as […] Continue reading ATmega328P – measuring its own supply voltage III  Here is a brief follow up from yesterday’s post on the internal reference voltage VBG of the ATmega328P. I wrote a small test program where I wait for a variable delay time after switching the input multiplexer of the analog-to-digital converter to the internal bandgap reference voltage VBG. Using the AVcc of as the […] Continue reading ATmega328P – measuring its own supply voltage II  The trick is not new, it is utilized in the AVR transistor tester which you can buy for quite cheap money from China, and it has been discussed in internet forums for almost 10 years (see below for some links). The Atmel AVR microcontrollers feature an analog to digital converter (ADC) equipped with […] Continue reading ATmega328P – measuring its own supply voltage  I have now been using XeLaTex exclusively for quite a while for all my LaTeX work, which essentially means for everything: lecture notes, lecture slides, lab instructions, letters, reports,… For some shorter time the symbols in my equations would show up ok on screen but a bit blurry on printouts. I was looking for […] Continue reading XeTeX and your math is bitmapped? |
