I mentioned Fritzing two years ago and now I find coming back to use this software. Fritzing is an open source software initiative that was to support designers and artists ready to move from physical prototyping to actual product. Today Fritzing is an open-source hardware initiative that makes electronics accessible as a creative material for →
When I was designing the measurement circuit used in my How to measure smartphone power usage posting, I needed to design a RC low pass filter to it. I could have picked an electronics book and formulas in it, but instead of manual calculation I used Google to find a tool for that on-line. There →
The problem: I need to measure how much power different Android applications make the phone to consume. Measurement method: Measure how much current the phone takes from it’s own battery. So I needed to somehow attack a measurement device between battery terminal and battery contact on the phone. This could be made by using a →

The Rise, Fall, and Rise of Electronics Kits is an interesting article mentions that many older engineers first became interested in electronics through hobbies in their youth—assembling kits, participating in amateur radio, or engaging in other experiments. The 1970s and 1980s were great times for electronics hobbyists. But whenever it seems that there’s nothing left →
It is expected that Internet of Things use is expanding quickly. But what about their security? I strongly encourage to read article The Internet of Things Is Wildly Insecure — And Often Unpatchable by well known security expert Bruce Schneier. It says that we’re at a crisis point now with regard to the security of →
The Internet of Everything is coming. The Internet is expanding into enterprise assets and consumer items such as cars and televisions. Very many electronics devices needs to be designed for this in mind. The Internet of Things (IoT) will evolve into the Web of Things, increasing the coordination between things in the real world and →
Yesterday evening tech news were all about Standardized Laptop Charger Approved By IEC. The IEC, the standards body which wrote the phone charger specification used in the EU, has approved a standardised laptop charger. IEC is optimistic that it will lead to a reduction in electronics waste and make it easier to find a replacement →
