Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried!
This breakout is best used for projects such as voice changers, audio recording and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6" away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp!

Using it is simple
Connect GND to ground, VCC to 2.4-5VDC.
For the best performance, use the "quietest" supply available (on an for Arduino, this would be the 3.3V supply). The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required. The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need an audio amplifier (such as 3.7W stereo amp) if you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the OUT pin directly to the microcontroller ADC pin. For audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into frequencies.
MC4 connectors are single-contact electrical connectors commonly used for connecting solar panels. The MC in MC4 stands for the manufacturer Multi-Contact and the 4 for the 4 mm diameter contact pin. MC4s allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand, but require a tool to disconnect them to ensure they do not accidentally disconnect when the cables are pulled. The MC4 and compatible products are universal in the solar market today, equipping almost all solar panels produced since about 2011.

NFC NTAG213 tag stickers are small adhesive tags that use Near Field Communication (NFC) technology to wirelessly transfer data when placed close to a compatible device, like a smartphone. The NTAG213 chip is specifically designed for simple and versatile NFC applications, featuring a memory size of 144 bytes and operating at a frequency of 13.56 MHz. These stickers are popular for a wide range of applications, including:
1. Smart Home Automation: Can be placed on objects or around the house to trigger actions on NFC-enabled smartphones, such as turning on lights or setting up scenes.
2. Contactless Sharing: Used for storing small amounts of information like URLs, contact information, or Wi-Fi credentials, making it easy to share with others by tapping a smartphone.
3. Inventory and Asset Management: Can be used in retail, warehouses, or offices for tracking items, verifying authenticity, or updating inventory records quickly with a mobile device.
4. Marketing and Event Management: Often used in events, businesses, or museums where visitors can tap their phones on the sticker to get more information about an exhibit, product, or promotion.
5. Access Control: Can be programmed to unlock doors or perform secure actions when authenticated with compatible devices.
These tags are typically very affordable, making them a popular choice for many personal and business-related NFC applications.

These are suitable for DIY projects and the Raspberry Pi pcb as the 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.

Here is a video from CNC Kitchen, he teaches how to install embedment nuts into 3D-printed parts.
3D printing plastics often have low yield strength and cannot reliably produce threaded features. Embedded metal nuts provide stronger and more precise threading for hidden fasteners. The nut melts and reflows the plastic around it, enhancing its strength. However, there are design constraints - the nut must be on a part face and cannot be reinforced beyond the plastic's properties.
