Fresh hacks every day
Many of us here in the office (myself included) can't tell the difference, but the audiophiles out there who want the best sound from their resistors should check out [Troel's] write-up for making your own non-inductive graphite resistors. Graphite resistors have the traits for being non-inductive, have a negative temperature coefficient, and supposedly sound better. We liked the detail of his … [Read more...]
There are so many apps available for the iPhone, one might even say there are a plethora. We would like to take a moment to help you find a few that might help with your hacking projects. Ever have problems remember a formula when you need it? Need to track the acceleration of your brand new rover? How about beginners needing help remember resistor codes. Well, there's an app for that. Check out … [Read more...]
[jefffolly] published some straight forward plans for a passive volume control. It uses a resistive ladder built across the contacts of 12W rotary switches. Each resistor provides a 5dB difference, and he recommends using 0.1% tolerance resistors to maintain accuracy. The use of discrete resistors instead of volume pots means that the output is much more predictable. All of the RCA sockets were … [Read more...]
Embedded above is a short segment produced by Make about one of our most fundamental circuit components: the resistor. Although brief at just five minutes, it covers resistor basics and the historical development of Ohm's law. … [Read more...]
