The $5 Raspberry Pi Zero is a standalone computer that can be embedded in various applications, but maybe now it is time to add some extra features. It comes with a USB OTG port, meaning it can function as a USB device rather than a USB host. Thus, it can become a serial device with […]

Sometimes the float valve of a water tank may not work properly causing water to overflow and spread across the floor. Peter Jennings faced this problem in his storage area, and he had developed an alarm device to notify him when the water exceeds its normal range. Peter’s project includes a simple water sensor and

Recently I had the problem some expensive components did overheat in my server rack. The ventilation was not optimal and I had to install additional fans. Because this rack is in my office and I like a quiet working place, the ventilation had to be as quiet as possible. First I thought about buying a

Hi! Today I’ll explain you how to recover your bricked ATtiny microcontroller using your Arduino board. ATtinys are very popular due to their small form factor yet very powerful. While working with them you may accidentally brick the ATtiny. As arduino is extremely popular and really easy to use, I guess you have one or

Programmable thermostats are cool things. They let you set the room temperature according to your schedule and will automatically make those adjustments for you. If you use them the way they’re intended to, they could be a great way to save on home energy costs. They work perfectly for people with fixed daily schedules. You can set

A research team led by faculty scientist Ali Javey at Berkeley Lab have debuted the smallest transistor ever reported. A gate structure of just 1 nm long can bring Moore’s law back again after the demonstration of the recent Silicon (Si) transistor with 5 nm gate. It was predicted that transistors will fail below 5

What is it? The SilentSwitcher is a solution for powering your small-signal audio circuits with quiet, low noise and efficient power, totally separated from the mains. Audio projects are steadily getting smaller and the power supply with its transformer and rectifier and reservoir caps remain as large and looming as ever. I had been looking at

Introduction & Overview USB connections can transfer both information and power. UsbSafe² is a device for protecting USB-connected hardware from both excessive voltage, current and unauthorized data access. Unfortunately, the practice of “juice jacking” (accessing data from a device connected to a public charging station), has become all too common. UsbSafe² provides a unique combination

OH MySensor Platform While building my custom Home Automation system for my apartment I already designed some actuators in the form of my RGBW Controller. Several of these control the lighting in some of my rooms. To “intelligently” use your actuators (e.g. light, power, …) you need to collect some information first though. To do
