HOW TO – Simple Microphone Preamplifier
Tomi writes – “This is a simple microphone preamplifier circuit which you can use between your microphone and stereo amplifier. This circuit amplifier microphone suitable for use with normal home stereo amplifier line/CD/aux/tape inputs. This microphone preamplifier can take both dynamic and electret microphone inputs (preamplifier provides power foe electret microphone elements). The idea of this circuit is to keep the design as simple as possible to be easy to build. That was my goal when I needed a simple external microphone preamplifier for my mixer. The performance of the circuit is nothing superior but can be used with many not so serious projects.” Link.
Nice use of a mint tin! – “This site features projects and circuits for building stereo microphones from low-cost Panasonic electret microphone capsules. Included are Mid-Side, XY, and Blumlein microphone setups. In addition, there are interesting related circuits and links to sites with microphone information and parts sources.” 
Good show for the security minded makers out there – “Welcome to SploitCast, the podcast for hackers, geeks, and the security paranoid. We are a group of students and IT professionals that have decided to start a downloadable talk show. SploitCast will discuss a wide variety of topics; these include, but are not limited to, new vulnerabilities, exploit code, security and technology news, and possibly even cute little bunny rabbits (but don’t hold your breath). The SploitCast crew will also be conducting interviews and round table discussions with other members of the security industry.” [
Procure IR modules from an old VCR, Raphael writes “Some time ago, I came across the Lirc (Linux Infrared Remote Control) website and decided to build a serial port IR receiver. They had a list of suggested IR receiver modules, but I was unable to buy one, so I had to think of using something else. A IR Receiver module is usually a photodiode and a 38khz detector. Most of them have 3 pins. VCC, GND, an output pin. If a 38khz carrier is detected, the output pin will become active. Some modules are active low, and others are active high. It is sometimes required to use an inverter(eg: 7404) to get the correct signal.” 
This is the best application in the entire world for converting DVDs to iPod video, it’s one click – “HandBrake Lite is a horribly-mangled abomination of HandBrake, jettisoning its non-crucial features with the one-track goal of creating iPod-sized movies from DVDs. You only really need to click two buttons to rip a DVD for iPod. It’s as easy as that. Less stuff to read, and fewer confusing words. All videos are automatically resized to 320px wide. Widescreen movies are properly cropped before conversion. Smaller interface, easier to stash away on your screen somewhere.” 
Justin Frankel (Winamp & Ninjam creator) has a new multitrack recording software called REAPER. This is a pretty good PC program to try out, small, fast, looks like it can tap in to your system sound for recording Skype or other VoIPs too, that could be useful for podcasts, etc. Don’t fear the Reaper, it’s free, for now.
