Depending on how hard your relay works, you might want to add a heat sink to it.
Q:During continuity testing with my multimeter why does my relay on the AC side not switch on?
A: The below info was found at http://www.crydom.com/en/tech/newsletters/solid statements - bench test an ssr.pdf
A multimeter determines impedance by injecting a small amount of voltage through it's probes into the circuit being tested. It then measures the current flowing through the probes and calculates resistance. Easy enough; Resistance = Voltage / Current! However, as we just discussed above, a solid state relay’s output turns on by “stealing” a bit of voltage from the AC mains in order to supply current to the gate of the SCRs. Simply put, if the AC mains is not connected to the relay then the output cannot turn on. Since the voltage and current produced by a multimeter is not sufficient enough to turn on the SCRs, the output of a solid state relay will remain in the off state; even with the input signal applied. As a result, SSRs will sometimes fail an incoming inspection because the engineer expects to see a significant change in the output impedance when they turn on the relay.The most effective way to bench test a solid state relay is to construct a simple test circuit consisting of a DC power supply or battery (a 9Vdc battery will work fine in most cases ) and a 60W or 100W light bulb.

How to use the card reader?








Hot Question:
1) Where can i download the software?
Answer: You can download the software via this link:http://www.nsccn.com/download/soft/nfc/nfcPro_wbw.exe
2) Which chip inside in the 5pcs blue keyfobs and 5pcs white cards?
Answer: If you buy the RFID copier + 5pcs UID keyfobs + 5pcs T5577 cards. The 5pcs UID keyfobs is working with 13.56MHz frequency, used to copy the MF 1k card. The 5pcs T5577 cards is working with 125KHz frequency, used to copy the EM4100, TK4100 cards. They are different type card.
3) Why the 5pcs cards in the package read failure?
Answer: Please don't worry, these 5pcs white cards is T5577 (EM4305) type, they haven no data before write. They will can be read successfully after finished written from your TK4100 or EM4100 type card. Thank you.

These are suitable for DIY projects and the Raspberry Pi pcb as the screw outside diameter is only 2.5mm that fits in the Pi mounting holes.
Brass standoffs are essential components in electronic projects, particularly in applications where circuit boards need to be securely mounted within an enclosure or chassis.
Here's how they are typically used:
Board Mounting: Brass standoffs are used to elevate and secure printed circuit boards (PCBs) within an electronic enclosure or chassis. They provide a stable platform for the PCB, preventing it from coming into contact with conductive surfaces that could cause short circuits.
Mechanical Support: Standoffs act as spacers between the PCB and the mounting surface, ensuring proper ventilation and preventing heat buildup. This is crucial for maintaining the integrity of sensitive electronic components.
Isolation: Brass standoffs help to electrically isolate the PCB from the chassis or enclosure. This isolation is essential for preventing electrical interference, reducing the risk of noise and signal degradation, and enhancing overall circuit performance.
Easy Access: Standoffs facilitate easy access to the PCB for maintenance, repairs, or upgrades. By raising the board above the mounting surface, technicians can easily reach components and make necessary adjustments without disassembling the entire system.
Vibration Dampening: In applications where vibration is a concern, brass standoffs can help dampen vibrations transmitted to the PCB, thereby reducing the risk of component failure or solder joint fatigue over time.
Grounding: Depending on the design, brass standoffs can also be used as grounding points for the PCB. By connecting the standoffs to the ground plane on the PCB, they provide a convenient and reliable grounding solution.
Overall, brass standoffs play a crucial role in ensuring the structural integrity, electrical isolation, and proper functioning of electronic systems. Their versatility and reliability make them indispensable components in a wide range of electronic projects.

We have used the HC-SR04 Ultrasonic Distance Sensor many times and for many good reasons. It is pretty easy to use, it performs well, and it is very inexpensive. For collision avoidance robots or intruder detection, this sensor is usually all you’ll need.
However, using the HC-SR04 outside is a different story. It is a pretty fragile device and can easily be damaged by dirt, or even high winds. And, above all, it is not waterproof.
For these circumstances you can use this sensor, in more weathered states, even outdoors.

Sensor Usage
Basic working principle
(1) using IO port TRIG trigger location, to the high level signal of at least 10us;
(2) module automatically sends 8 40KHz pulse, automatic detecting whether a signal returns;
(3) on signal return, a high level is output through the IO port ECHO, the time duration of the high level is ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;
