Two PCBs from earlier projects were used in this project: LoRa breakout board Sensor PCB with Si7013 humidity sensor from multisensor LoRa project … and particle sensor. Particle sensors could be cheap and easy to use. Disadvantage of lowest cost PM sensors is lack of “calibration”. The best method to measure particle content dispensed in …
Everything implies, that the situation with marking of chip resistors (0603/0805/1206) will soon be similar to chip capacitors – i.e. no marking on the top of the component. The reason for this step is to reduce unnecessary chemical usages for environmental protections. Naturally, to identify the product resistance value, each single reel will be labeled …

Step 4: Identify Memory Needs Flash and RAM are two very critical components of any microcontrollers. Making sure that you don’t run out of program space or variable space is undoubtedly of highest priority. It is far easier to select a part with too much of these features than not enough. Getting to the end …
1A DC/DC switch-mode regulators TRACO TSR-1 already found their stable place on the market and they successfully replace inefficient linear regulators. Switch-mode power supplies are still more used in all segments of power supply, to which also belongs a regulation on the side of the load (Point Of Load – POL). Perhaps every designer is …

Of the hundreds of projects I’ve shared over the years, none has attracted more attention than my DIY ECG machine on the cheap posted almost 4 years ago. This weekend I re-visited the project and made something I’m excited to share! The original project was immensely popular, my first featured article on Hack-A-Day, and today “ECG” …
n their most basic form, charge pumps are circuits that generate a voltage larger than the supply voltage from which they operate. Traditionally, charge pumps have been perceived to have limited voltage capability, offering performance that is seen as filling a niche in the range between low-dropout LDOs and switching regulators. Nonetheless, there are benefits …
Using the RFduino USB shield, simply plug the RFduino into a USB port of any computer and use the Arduino IDE to load your Arduino sketch, which automatically begins running on the RFduino. Then you can detach the RFduino USB shield and plug the RFduino directly into your project. RF dui no In The News: …
