Low-Fi for the living room II

Low-Fi for the living room II

The last weeks the speaker box has been in use and proved to do quite well, with a notable exception. While the speakers were able to produce actual bass, they started to distort quite early. Too early for some kinds of music to be listened at a normal volume. So, as there is enough space and volume for a subwoofer, …..

Good solutions don’t need to cost much

Good solutions don't need to cost much

Well, I was about to title this “Good solutions are sometimes simple”, but they are most of the time. In my journey to get rid of paper as thoroughly as I can I’ve already cursed my Tablet’s dock. It sits nearly flat on the ground, which is not bad for typing, but if you want to use it as a …..

Shots of the uPOV in it’s full glory!

A little outlook of what is to come soon

There’s been a lot of hassle around the house again which keeps me from being unproductive in the most preferable way – by tampering all kinds of hardware. So I couldn’t order a set of new toys early enough to arrive in time for some easter fun.

The Low-Fi box has proven to be too Low-Fi and will get a subwoofer. …..

Progress

Its been a while since I’ve done any work on the Arduimometer, but I think I’ve made a step in the right direction.

Using eagle cad, I’ve thrown together a breakout board for the DS3231M+ real time clock for testing purposes. Once I’m happy with the schematic, I’m going to bring it over to create the PCB layout. From there, I’ll …..

Low-Fi for the living room

Low-Fi for the living room

Yes, I have been absent for quite some time. Besides a bit of stress related to the usual triple of university, work and private life there’s been a lot of death and illness. Death is most notable for one of our cats, that passed away at the biblical age of 21. A week after that my GF took a leap …..

A Logic Analyzer using Audacity

A Logic Analyzer using Audacity

If you are interested in observing digital data lines, such as the I2C bus, but do not have a logic analyzer — yet are lucky enough to still have a parallel port on your computer, this hack (I won’t say program) hopefully will help.  It captures the logic levels present at the input of the two data pins, D0 and …..
