LPG Gas Sensor

No Comments »

Here is sensor of liquefied petroleum gas, also called LPG, GPL, LP Gas, liquid petroleum gas or simply propane. The SEN-1327 LPG Gas Sensor Module is designed to enable LPG detection interface to Microcontroller without ADC Channels. It allows to determine when a preset LPG gas level has been reached or exceeded. Interfacing with the sensor module is done through a 4-pin SIP header and requires One I/O pin from the host microcontroller. The onboard microcontroller provide initial heating ......

Simple USB Power Injector For External Hard Drives

No Comments »

A portable USB hard drive is a great way to back up data but what if your USB ports are unable to supply enough to power the drive? As with most such drives, it is powered directly from the USB port, so it doesn’t require an external plugpack supply. In fact, the device is powered from two USB ports, since one port is incapable of supplying sufficient current. In use, the two connectors are plugged into adjacent USB ports, so that power for the drive is simultaneously sourced from both ......

Tube Clock digital

No Comments »

This clock is made up of four IV-17 alphanumeric VFD tubes. As it ships, the electronics come in two parts – the base with the microcontroller and the shield with the VFD tubes. The base can support up to four sixteen-segment tubes or twenty seven-segment displays. It ships with an ISP header for easy software upgrades. If you want to make your own four letter word machine or to experiment with VFD tubes, this is a great place to start. I received this device fully assembled but it ......
