Fits in type 6063-T5 aluminum junction boxes 71*25*85mm
PIC Firmware (as a complete MPLABX Project) attached for a basic transparent gateway function.
Only 300 lines with no dependent libraries so Easy to understand and modify to your favourite CPU as required.
USB dongle Real time clock For raspberry Pi (which does not have one)
Initializes as a USB Serial port when plugged in to any computer and times can be read and set via serial commands
Microchip XC8 Project attached below
PCB Shown is revision 3 as I have been trying to fit it into a small USB dongle enclosure, the one it seems to fit best is the USB-7201-G from Bud Industries.
Miniature amplifier with adjustable bass boost, gain, and volume controls. Uses 1/8" (3.5mm) headphone jacks on the input and output. Powered by USB or 9v (4-12 VDC, max of 15 VDC).
Parts list for Digi-Key is attached below in an image and excel file.
A USB header for PC motherboards designed to be as minimal as possible. It may interfere with components on some motherboards. Its intended use is for keeping small flash-drives, wireless controllers, or USB license keys inside a computer enclosure.
It can also be a powerful tool for computer techs who can keep two USB tools together such as a diagnostics OS on flash drive alongside a wireless k...
USB RS232 Relay
The main objective of this board is to ring an school bell using a PC program written in python.
- This project is the interface of a PC to a Relay using a simple USB RS232 adapter.
- This approach was selected because the parts are easily found in any PC parts store.
- The relay is activated/deactivated using the RTS line of the serial port, any...
![enter image description here]- Load resistor(нагрузочный резистор)
Charger 5V on KP142EH5A with radiator for transistor VT1 and with load resistor. **(WITHOUT LOADING THE OUTLET SCHEME WILL GIVE SAME THAT AND AT THE ENTRANCE !!!)**
Зарядка на 5V на основе кр142ен5а с радиатором для транзистора VT1 и нагрузочным резистором. **(БЕЗ НАГРУЗКИ СХЕМА НА ВЫХОДЕ БУДЕТ ДАВАТЬ...
This power supply is very simple in that it derives its power from a USB socket, and allows feeding of the circuits that require 5V, is also present an integrated LM317 that with the values of R1 and R2 chosen provides in output a voltage of 3, 3V (see diagram)
The self-resetting fuse F1 protects your PC, the power supply can be switched off by pressing the switch SW1 while the lighting of the PW...
The FT232R is the latest device to be added to FTD I’ s range of USB UART interface Integrated Circuit Devices. The FT232R is a USB to serial UART interface with optional clock generator output, and the new FTDI Chip-ID™ security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to serial designs using the FT232R have been further sim...
