They can play computer demo multimedia with old game consoles, Arduino+LED sign, LEGOs and audio mixer… Many cool hacks I would say!  Assembly Summer 2017 event is still going on, more videos at AssemblyTV at YouTube and Assembly Summer 2017 pages. →

RF attenuators are a universal building block within the RF design arena. I neeeded some RF attenuators for my electronics lab. I found this cheap product  DC-4.0GHz RF Fixed Attenuator from Banggood. They seemed to have pretty good specfications and features considering that the price is just slightly over 7 Euros for three attenuators: Frequency →

Edge computing could push the cloud to the fringe Peter Levine believes that cloud computing is soon going to take a back seat to edge computing — and we will very quickly see the majority of processing taking place at the device level. As crazy as that sounds — and →

The Rane Library has many interesting audio relaed technical documents. The most famouse of them is Note 110 Sound Systems Interconnections – it is a classic. Just few days ago I happened to look around at The Rane Library, and found some really interesting material related to audio systems and ground loops: Grounding and Shielding →
