I just finished a new quickie project: The Headset to XLR phantom voltage adapter. This adapter / converter makes it possible to use your low voltage electret microphone on a professional audio interface with 48V phantom power. I was astonished to learn how low the noise floor of my headset really is, if only it […]

I also supected power counters for these additional planes might actually exist in hardware but are just not exposed by […]

Yet, people struggle to get acceptable energy figures for the complete system besides all claims of high energy […]

Apparently some of the early models were susceptible for this cable to break. Official repair by Canon costs more than a brand new lens, but aftermarket cables are available. It is not so […]
