Temperature-to-period circuit provides linearization of thermistor response

Designers often use thermistors rather than other temperature sensors because thermistors offer high sensitivity, compactness, low cost, and small time constants. But most thermistors’ resistance-versus-temperature characteristics are highly nonlinear and need correction for applications that require a linear response. Using a thermistor as a sensor, the simple circuit in Figure 1 provides a time period var ...

DIY USB 5V Solar Power Bank

Solar energy is renewable, free, widely available and clean form of energy. It is considered as a serious source of energy for many years because of the vast amounts of energy that is made freely available, if harnessed by modern technology. Many people are familiar with so-called photovoltaic cells, or solar panels, found on things like spacecraft, rooftops, and handheld calculators. The cells are made of ...

Creating footprints in KiCad using a scanner

Some time ago I sourced a number of very cheap SD card sockets from China for a hobby project I was working on. Sadly, when it came to PCB design, I couldn’t find the footprints for this particular socket anywhere – the part being a proprietary invention of the factory rather than a cheap knockoff of a reputable brand like Amphenol or Molex for which drawings are readily available off of snapeda.com. Turns ...

Lithium-ion battery fires: 7 solutions for improved safety

I would feel so much safer on my next flight from Phoenix to Silicon Valley if I knew that there were safeguards in place inside passengers’ smartphones that could prevent fire and explosion from such design decisions like a company packing 10 pounds of Lithium-ion battery into a 5 pound compartment or a smartphone owner buying a lower cost, after-market battery replacing the original battery in their phone ...
