Here is an example of DIY 18650 Charger using a TP4056 Lithium Cell Charger Module by Tinker Man Mick:
Single-cell lithium base battery charger & protection module. The charging will be via a micro B connector. Lithium base battery includes Li-po and Li-ion battery as the charging and discharging characteristic is similar.
The USB micro B connector power input offers direct charging using widely available nowadays with power bank and also Android phone charger. With a maximum charging current of 1A, your battery can be charged faster and of course, do make sure the 5V input has sufficient power to provide more than 1A.
It comes with a TP4056 charging IC.
Using the module
- Connect micro USB cable for power, or 5V DC to pads marked IN+ and IN- on left-hand side of the module
- Connect cell to charge to B+/B- pads on right-hand side of module
- A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side
- Important! Disconnect load when charging
- The red LED indicates chaging in progress, green LED indicates charging has finished.
- Never charge your battery at a rate greater than 1C.
- Single Cell Lithium-based battery charger.
- USB Micro B connector for power input
- 5V input pads for DIY/custom input.
- Input Voltage: 5VDC
- Charging voltage limit: 4.2VDC
- Minimum discharge voltage: 2.5VDC

Note: This M.2 case is compatible with both NVMe and SATA SSD.
Some people must be tired of using small SD cards as memory space with low performance and specifications. It's time to change! Let's upgrade to SSD storage instead of using the normal SD card. The problem is most computer, smartphone, and Raspberry Pi does not have the socket for SSD storage. To overcome this problem, you just need a portable drive!
Plus, this case can be used with 4 variations of M.2 size (2230, 2242, 2260, 2280). It also comes with a USB C to USB 3.0 cable, so that you can directly connect to Raspberry Pi or any computer.
With this external M.2 NVMe storage, you can just boot the preferred Operating System for the Raspberry Pi 4 Model B direct from the USB! Interesting right? You just have to slot in your M.2 NVMe with preloaded Raspberry Pi OS and plug it into your RPi board. No driver is needed. Plug and play, straight out of the box. :)

Are you working on a project involving a fire-detecting robot or a smart system that requires flame detection? This versatile sensor module is tailor-made for your needs. Equipped with a flame sensor and an adjustable digital filter for digital output, it also retains the original analog output. This allows you to seamlessly integrate it into your setup either as a digital input or an analog input sensor, offering the flexibility of a minimum 3-wire interface or an optional 4-wire connection that utilizes both digital and analog functionalities.
Designed to detect fire or other light sources within the wavelength range of 760 nm to 1100 nm, the flame sensor has a pivotal role in scenarios such as fire-fighting robots and soccer robots. With a wide detection angle of 60 degrees and high sensitivity to the flame spectrum, this sensor serves as the "eyes" of the robot, enabling it to identify fire sources or specialized light sources like those used in a soccer game. The module even features M3 mounting holes for convenient installation onto your robot.
Operational within a temperature range of -25 degrees Celsius to 85 degrees Celsius, the flame sensor must maintain a safe distance from the flame during operation to prevent damage. It's compatible with various microcontrollers that support digital or analog input, such as PIC, SK40C, SK28A, SKds40A, and the Arduino series. Moreover, when coupled with a relay module, it can serve as a flame switch for added functionality.Features
- Detect fire, detect light source and sensitive to light with wavelenghth of 940nm
- Interface:Analog or digital
- Supply Voltage: +5 V
- Detection range: 20cm (1V) ~ 100cm (4.8V)

It's built with rectangular shape section, tougher and keeps print bed level better. The thumbwheels under your heat bed might be rotated itself and the weak springs get loosen after long-run printing (due to movement or vibration). If you're tired of leveling your bed constantly, better springs are a very inexpensive upgrade to your 3D printer! With this kind of strong springs, you won't need to level your bed between prints nearly as often.

CH340 is the new popular USB to UART converter/bridge for maker. It is being widely used in many development boards which includes:
- NodeMCU with CH340
- Maker UNO
This is a cable that embeds CH340 in it and extended the useful pins out to female headers.
The cable is the easiest way ever to connect to your microcontroller/WiFi router serial console port. Inside the big USB plug is the CH340 USB <-> Serial conversion chip and at the end of the 1-meter cable are four-wire:
- Red is power, or VCC, 5VDC
- Black is ground or 0V
- White is RXI input to USB's UART port, Receive input of USB's UART
- Green is TXO output of USB's UART port, Transmit output of USB's UART
The power pins provide 5V @ 500mA direct from the USB port and the RX/TX pins are 5.0V logic for interfacing with the most common 5V logic level chipsets.
Because of the separated pin headers, this cable is ideal for powering and connecting up to the debug/login console on the ESP32-CAM as ESP32's IO pins are 5V tolerant. We have tested this USB to UART converter with ESP32-CAM and it works fine.
This is easier to use than an FTDI cable in many cases because the wires are separated. Note that we call this a "TTL cable" (since that's what they're called) but technically it's CMOS logic.
It will appear as COM port after being plugged into the computer/laptop's USB port and after driver installation (1st and one time only).
Note: This cable is NOT SUITABLE for Arduino re-programming such as a BBFuino, Pro-Mini, etc. because it does not have the DTR/RTS wire necessary for initiating the bootloader reboot sequence.
- USB to UART TTL
- CH340 IC
- Extended the Power and UART pins:
- Red = V_USB, 5V
- Black = Gnd
- White = USB_RX
- Green = USB_TX, 5V logic
- V_USB is 5.0V while TX and RX are 5.0V too
- Cable length: 1 meter

In case your thermal pads for the Raspberry Pi mainboard are getting bad or old, you can use these pads to replace them.
It comes in two pieces, one dedicated for the CPU (in square shape) while another is meant for the RAM IC (in rectangle shape). Both sides of each thermal pad are adhesive and of course, come with a protective sheet that you need to peel off before sticking it to the IC or heatsink surface.
These thermal pads will ensure efficient heat dissipation to the heatsink from the CPU and RAM IC on the Single-board computer. Make sure the Raspberry Pi is in cool condition in any situation :)
- Simple and effective thermal pads
- Comes in two pieces
- One for CPU and another for RAM
- Can be used as a thermal paste for the heatsink as both sides of the pads are adhesive surface
- Perfect fit for Raspberry Pi 3, 4 and 5 mainboards.
