Everybody knows how Internet goes through copper wiring, fiber optics and wireless? But are the other communications media that could be uses? Yes there seems to be some unexpected ways to transport data. A core part of the hacker mentality is the desire to test limits: trying out ideas to see if something interesting, informative, →
Who remembers Phone booths and above all phone cards? Phone cards were a technological advance in the world of public telephone traffic in the 1990s. They allowed to make calls on many phone booths in Finland and phone cards were also a popular collector’s item, collected both used and unused: Telecom companies have placed advertising →
I just saw this Facebook post in AC Disaster group and had to react to it! Source: Post by Jerry Hicks at AV Disasters Facebook group (used with permission) Almost clever! You can actually plug in US charger to speakon connector and have it to make contact with two “pins” (1- and 2-). You can →
In this post I am talking about adapting 10 and 100 megabit twisted pair Ethernet to use coaxial cable instead of twisted pair wiring. Those 10BASE-T and 100BASE-TX Ethernet st standards use two wire pairs for communications (one for TX and other for RX). In this article I am describing how to adapt them to →
Ethernet started as a network that runs over coaxial cable. Over years the Ethernet has started to use mainly twisted pair wiring and fiber optics for communications. There seems to be every now and then still questions related to running Ethernet over coaxial cabling. This is the first part of multi-part post on running Ethernet →
I saw an advertisement video of LED hat on Facebook some days ago. This kind of had might not be the best idea to wear on many parties, but maybe could have some uses for advertisement purposes. This kind of LED hat is something that makes hacker mind spinning. The hat had wireless connection so, →
This is a pretty interesting hardware hacking article: https://www.bunniestudios.com/blog/?p=3554 Some SD cards contain vulnerabilities that allow arbitrary code execution — on the memory card itself. On the dark side, code execution on the memory card enables a class of MITM (man-in-the-middle) attacks, where the card seems to be behaving one way, but in fact it →
happen to own IKEA Bekant motor adjustable table. It worked nicely for around years, and served well as my working table. Though there are only simple “Up” and “Down” buttons installed by default, it works OK. But one day I found out that some day moving the table up and down did not work anymore. →
This is nuts old-school hardware hacking reported at https://blog.hackster.io/video-pong-made-with-all-discrete-components-cbffe6a2721d and https://hackaday.com/2019/09/17/building-video-pong-with-discrete-components/. It seems that this was a slightly masochistic undertaking. The trick is that this classic video game is made out of discrete components — it is 100% IC free. I like the beauty of it’s complex wiring! Look at the video of it: There is →
I have had for a long time an AKG D60 S microphone. The AKG D60S is advertised as an unidirectional semiprofessional dynamic microphone with smooth frequency response, a rugged all-metal body, an on/off switch, and removable wire-mesh grill. It was proven to be a decent semiprofessional all-round microphone with hypercardioid polar pattern. Hypercardioid microphones are →
