New Dynamic Duo, Arduino and Eclipse

There are a lot of solutions to programing an Arduino: the default avr-g++, Studio, etc. But [Sandeep] let us know about using one of the more powerful IDEs out there, Eclipse, to do the same. We’ve already outlined why Eclipse is a great IDE but now the fact that you can use it in your MCU based projects adds to its usefulness and already large feature list. However, don’t be turned off by [Sandeep's] tutorial. While it is aimed at people who are completely new to setting up an IDE and working with an AVR, the tips certainly can benefit even the most experienced hacker.

Open source logic analyzer software

[Christian Weichel] has been hard at work developing LogicAnalyzer, an open source tool that may interest you. It is designed with SUMP Logic Analyzers in mind but a main goal is expandability. What this means is that it plays nicely with things like the Open Workbench Logic Sniffer or you can do a bit of fiddling to get it to work with your own designs. The program is based on Eclipse so you should be familiar with how it works and you can get it running easily on multiple platforms. Take a look at the wiki for a quick start.

New AVR simulator for Linux

simavr is a software simulator for the AVR line of microcontrollers. You might be asking why anyone would write this sort of thing considering the simulator provided with AVR Studio is a wonderful tool? Well, a lot of folks don’t run Windows and don’t wish to use that development environment even if Wine or Virtualbox could make it happen.

We haven’t tried it out ourselves yet. There is a discussion thread going that reports some positive results of using simavr with GDB and AVR Eclipse. It’s a new package, but so far it seems to have put its best foot forward. Currently there is support for ATtiny25/45/85, ATtiny13, ATmega48/88/168, andATmega164/324/644 chips. Several of the common on-chip peripherals are already supported with the others on the way.

Have you tried it out? Let us know what you think in the comments.

Russian homemade telescope


In the Russian city of Barnaul, some enthusiasts are gathering their resources to revive a home made telescope and observatory. Built by [Mikhail Levchenko], in the mid 70’s, the telescope is quite impressive. [Levchenko] kept his hobby somewhat of a secret so as not to arouse the suspicions of his neighbors, but its pretty hard to hide a tower as tall as a house with a domed observatory on top. The telescope itself has a 16 inch glass lens that provides 500x magnification. His hobby would turn out to have a pretty big impact on the town. People would come to him hoping that his telescope could tell their fortunes. Not a believer in horoscopes, he tried to educate people with lessons in astronomy and physics. One man was said to have given up drinking after seeing Saturn.

[Levchenko] passed away in 2002 and his observatory fell into disrepair. Local thieves tried to steal pieces for scrap and the whole structure has sunken somewhat. Some of those who were inspired when young by [Levchenko] have decided to renovate it for the eclipse. Barnaul will be a prime location for viewing. The total renovation and possible relocation will cost around 2 million dollars.

In the past, we covered a high powered telescope made by some girl scouts, and this $40 USB telescope looks fun too.
