I’ve been interested in DIY Electronics for some time. And to get started I decided to build a small chip amplifier for myself. I barely know anything about designing/building an amplifier. So i relied on Google, and word of mouth to finalize the design for the basic power amp stage based on the TDA7240 IC . I’ve purchased the components and assembled them onto a perforated board after testing it on a breadboard.
Here are a few pictures of the current state of my project.
The Heatsink was “liberated” from a non-functional ATX Power Supply. The amplifier is currently powered by another ATX Power supply that is hotwired.
I’ll put up detailed schematics, and partlists once I draw them properly. Till then take a look at the TDA7240 Spec Sheet
I’ve been thinking and planning to build/install a custom version of either devian or ubuntu which will be installed on a USB Drive for carrying arround wherever I go.
I want this to achieve the following
- Porvide a fully functional bash shell.
- Allow a X server to run with either Fluxbox or XFCE.
- Synchronise with Local copies of Applications like Evolution and Opera
- Have basic multimedia features.
I thought it would be better to have two partitions. A FAT32 Partition to store all my data (will be mounted under /media/data of /home/surajram/data). This partition should be accessible by traditional Windows or DOS OSs. I guess it would be best to make the other partitition as ext3. I am also thinking of using an alternate filesystem like reiserFS, have to consider the performance differences.
Debian GNU/Linux is my favorite Linux distribution for servers and most desktops. It’s wide availability of binary packages combined with a strong developer/support community makes it my favorite.
Invariably, every time I install Linux, i tend to remove a lot unused packages from the new system. So I have come to the conclusion that the minimal install is what i need to begin with for all requirements.
This post should guide you to install a minimal copy of Linux.
