Boss Tremolo TR-2 w/ C4 Mod +Gain Boost

Posted on July 15, 2010August 26, 2016 by abram

This little guy is currently on eBay. I always thought that this tremolo wasn’t bad, but the volume drop was insatiable and drove me nuts sometimes. I thought I would try modding this one by cutting out the C4 cap (a 0.1uF bypass cap) which is the alleged cause of the gain loss. It is,…

Posted on July 14, 2010July 14, 2010 by abram

Let’s say you need to direct port 8888 on your external IP address to port 80 on a machine inside your network. You begin this process by logging into the router and running enable and entering config mode. router> enable Password: ******** router# conf t router(config)# For the sake of simplicity, we’ll assume that there…

Posted on July 1, 2010 by abram

here’s another audio snippet from a beautiful pass over long island. much clearer than before. considering the signals are traveling from more than 200 miles away, it’s surprisingly clear (at moments) for a hand-held transceiver.

Signals… from space?

none other than. yesterday, i attempted to record some very weak signals for the amateur satellite, ECHO AO-51, with my trusty Yaesu VX-3R. most of my attempts had been unsuccessful until i bought an additional Nagoya N-771 antenna to accompany the tiny 2m/70cm dual band radio. however, i have intercepted the signals from the low-earth…

Typical Alkaline Battery Ratings

Posted on June 29, 2010June 29, 2010 by abram

Also posted on the 8088 Networks site. I was using this to create a small external power supply for my Yeasu VX-3R. I used a 9v battery initially and realized that I should use a voltage drop to improve the battery life. Without any sort of voltage drop, the battery was dead in a little…

things are complex. life is a system. systems are inherently complex. it’s easy to be complex. it’s easy to get lost in the complexities of nature and the bull shit systems that human beings create to entertain themselves. it’s easy to attack what we don’t understand. it’s easy to draw the line between you and…
