Hackaday featured today LPT DAC circuit. Back in the olden days, around 25 years ago, sound cards were rare on PCs. One hack those days was the original Covox Speech Thing, that connected a simple DAC to to PC parallel port. The Covox Speech Thing (also known as Covox plug) was an external audio device →
Technologies for making things invisible is always interesting. There are active and passive technologies that have been tried for this. My earlier posting Mercedes uses LEDs to create invisible car showed and active technology that used camera + huge LED display to make invisibility effect. Yesterday I saw a new interesting passive one. Researchers Develop →
Spintronics is an emerging technology exploiting both the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices. Spintronics differs from the older magnetoelectronics, in that the spins are not only manipulated by magnetic fields, but also by electrical fields. Spintronics emerged from discoveries in →

What is the best free or cheap electronics design software? It is hard to say in this ever changing field. I some time ago mentioned some software examples in Top Free Electronics Design Tools posting and you can find a long comparison list at Wikipedia Comparison of EDA software page. For the circuit design I would →
