UT204 from company UNI-Trend is a near relative to the UT203. multimeter. Already UT203 provides a lot of user comfort and a very pleasant feature – measuring of a DC current without interrupting a measured circuit. However UT204 is different from its “weaker” brother in one essential thing – it enable measuring of a true
UT204 is able to measure DC current and also True RMS Read More »
The purpose of this Design Idea was to improve reliability, add new features, and replace a latching power switch with a momentary one. The features are: The switch has foolproof protection against too frequent switching, which can be harmful for many applications. It can handle significant power because manual control and switching are separated. If
Momentary switch controls mains with latch-on and remote shutdown Read More »
The RFM69HCW is a highly integrated RF transceiver capable of operation over a wide frequency range, including the 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. Its highly integrated architecture allows for a minimum of external components whilst maintaining maximum design flexibility. All major RF communication parameters are programmable and
RFM69HCW transceiver can go up to 20dBm Read More »
Description This is my second encounter with LM3886. I was pleased of the sound this chip produced the first time, so I decided to make another amplifier with it. The schematic is based on the schematic in the datasheet of the chip with minor changes. I removed the time delay capacitor connected to MUTE pin,
