Power meter (Part 2)

Part 1, 2, 3 I have been tumbling through the net, looking for interfaces to the TIC. So far, I found two types of reference designs: The quick, dirty, safe but questionable design The academic design Most of the interfaces described on the web are very basic. They feature a single optocoupler and a biasing […]

Random number generator (Part 1)

Part 1, 2, 3 As I was stumbling the web looking for advanced information on thermal noise, I found some very interesting papers on RNGs, aka Random Number Generators. These devices feature hardware components which are responsible for a generating unpredictable random numbers ! This is a very interesting matter as it involves physics, electronics, […]

Engine RPM (Part 3)

Part 1, 2, 3, 4, 5 Previous posts on measuring engine RPM are featuring electronic interfaces with devices that sense the engine rotation. It is sometimes impossible to connect such sensor so that other techniques must be used in order to check and adjust an engine RPM. Today, we will use a contact-less technique featuring a light beam directed […]

When the compiler matters (Part 1)

Part 1 Recently, I worked on a library to manage LED strips. It worked perfectly using the Window’s version of Arduino. It worked as well on the GNU/Linux’ version with a LED strip… but not with another strip ! An advanced issue for an advanced headache… In the Arduino environment , when the “verify” or […]

Picoscope (Part 1)

As technology improves, the size, performances and cost of measurement instruments changes over the time. Few months ago, we described the RIGOL 1052E which was pretty new at this time. As we were looking for a new equipment for the lab we decided to compare the various products available from the market. Before getting into the […]

RIGOL 1052E DSO (Part 3)

Part 1, 2, 3 Erratic clicks! Life goes on and the Rigol 1052E remains a reliable companion still purring and always ready to help diagnosing circuits and running prototypes testing. Sometimes ago, I experienced some strange changes in time and amplitude scales when using the notched rotary encoders. Values where jumping erratically from one value to an other, whatever […]

DURATOOL Soldering Station

Sometimes ago I decided that I was fed up taking risks at soldering tiny chips and components using my good old JVC soldering iron. By the way, I strongly recommend this beast of burden which is still working absolutely fine after more than 20 years of use. This is a perfect companion for field service because of […]
