This is a neat trick to get strange sounds out of your audio mixer. This video shows the spectacular world of using no-inout-feedback-mixing to turn a mixer into a synth. You can get many possible sounds from just an old analogue audio mixer and an aux cable. Truly astonishing squirrrklly tones! Have you tried it? →
uun (unshielded untwisted notpair) UUP (unshielded untwisted pair) Unshielded but not so twisted wire pairs in this Ethernet cable It is essentially multiple twin lead transmission lines, but yeah, lacking the benefits of twisting. And there is that one “split pair” that goes to pins 3 and 6. If other pairs are close what they →
Very many electrical equipment and fluorescent lamps powered from 230V AC have a filtering capacitor on power input between live and neutral. This is typically there for interference suppressing. That capacitor is normally X rated “self healing” type, but they can sometimes fail. When they fail their case starts turning black, and they can start →
There has been 50 years for many significant technical innovations at the moment or just passed. For example there mobile phones and bar codes are now 50 years old. Also there is 50 years from the time people visited moon. Here are some news links related to them. The Matrix phone to the iPhone – →
This posting is here to collect cyber security news in April 2023. I post links to security vulnerability news to comments of this article. You are also free to post related links to comments. →
Arduino has released an official successor to the iconic Arduino UNO R3 board, the most well-known representative of the microcontroller platform and programming environment based on Arduino’s open hardware, has been released. The Arduino UNO R4 is the first major update to the venerable Arduino UNO R3, which has been around since 2010 and has →
An IPv6 address is 128 bits in length and consists of eight, 16-bit fields, with each field bounded by a colon. Each field must contain a hexadecimal number. Some IPv6 addresses look more funny than other addresses.

Power over Ethernet, or PoE, describes any of several standards or ad hoc systems that pass electric power along with data on twisted-pair Ethernet cabling. There are several common techniques for transmitting power over Ethernet cabling. Three of them have been standardized by Institute of Electrical and Electronics Engineers (IEEE) standard IEEE 802.3 since 2003. →
Gordon Moore, Intel Co-Founder, Dies at 94 Mar 24, 2023 https://www.intc.com/news-events/press-releases/detail/1611/gordon-moore-intel-co-founder-dies-at-94 Moore, who set the course for the future of the semiconductor industry, devoted his later years to philanthropy. Moore and his longtime colleague Robert Noyce founded Intel in July 1968. Prior to establishing Intel, Moore and Noyce participated in the founding of Fairchild Semiconductor, →
I bought this VGA signal generator module years ago from some web shop in China. It is designed to easily test your VGA monitor(s) (VGA/SVGA/XGA) with this handy tool. It can be also used as a general purpose video signal source when testing other video equipment that take in VGA signal (like video switchers, converters, →
