Machine learning possible on microcontrollers

ARM’s Zach Shelby introduced the use of microcontrollers for machine learning and artificial intelligence at the ECF19 event in Helsinki on last Friday. The talk showed that that artificial intelligence and machine learning can be applied to small embedded devices in addition to the cloud-based model. In particular, artificial intelligence is well suited to the

Bad wire connector teardown

I have earlier written about bad cheap Chinese wire connect that did not live up to specifications and was potentially dangerous for mains power at http://www.epanorama.net/newepa/2018/01/24/cheap-quick-wire-connector-block/ Here is teardown of that Let’s open open it Here was all.

Useless device kit

A useless machine is a device which has a function but no direct purpose. Typically it is an amusing engineering “hack“, or as an intellectual joke. The most well-known “useless machines” are those inspired by Marvin Minsky‘s design, in which the device’s sole function is to switch itself off by operating its own “off” switch.
