PicoDetector : a simple metal detector

Bruno Gavand build a simple metal detector using PIC12F683. He writes:

The idea of this circuit is to hack PIC oscillator circuit, by replacing the crystal by a coil : the frequency of the oscillator then depends on presence of metal near the coil, just like in a classic metal detector.

8 PIN PIC Development Board – PIC12F683

8-pin-pic-development-board-c085c-500x500

8 PIN SMD PIC development board is a full-featured development board and platform for 8-bit PIC® microcontrollers. This project is a versatile development solution, featuring several options for external sensors, off-board communication and human interface. Additionally, it offers ample room for expansion, making it an excellent solution for developers and engineers looking for a PIC development board. The 8 Pin SO8-SMD PIC Development / Evaluations Board demonstrates the capabilities of Microchip’s 8-bit microcontrollers, specifically, It can be used as a standalone demonstration board with a programmed part. With this board you can develop and prototype with all Microchip’s 8 PIN PIC microcontrollers which doesn’t required crystals (External Oscillator). On board connector for ICSP allows an easy programming. The board has configurable pull ups on all pins can be soldered or abandon as per requirement, All pins has solder Jumpers for pull down.  Onboard 5V regulator, two tact switch, one output connector to interface with 12V Relay board or solid state AC or DC Relay. Board has small prototype area. We have considered PIC12F683 IC for this Board.

One Channel Infra Red Remote Controller

H015-500x500

One Channel Infra-Red Remote and receiver with onboard Relay provides normally open and normally closed output. The project based on PIC12F683 Microcontroller from Microchip , TSOP1738 used as Infra-Red receiver. Micro-controller decodes the RC5 serial data coming from TSOP1738 and provides high output if the data is valid. The output can be set Momentary or Latch using on board Jumper (J1) and closure. The board provided with 3 LEDs, Power LED, Valid Transmission LED and Output LED. This Remote works with switch No1 of RC5 Remote.

Features

Electronic Live Capture Mousetrap

A mousetrap is a type of animal trap specialize to catch small animals, particularly rodents like rats, mice, hamsters, etc. This project is a kind of mousetrap that is intended to keep a captured animal alive. In this way, the hunter can release the captured animal later to the wild.

The PIC12F683 microcontroller acts as the heart of the project; it is programmed to meet function of the design. The sensor used in this project is a pair of infrared transmitter and receiver. An infrared LED connected to the GP2 pin of the PIC12F683 transmits continuous infrared signal to the TSOP1138 infrared receiver connected to the GP1 pin of the PIC12F683. To avoid the effect of ambient light, the generated signal at GP2 pin to the infrared LED is modulated at 38kHz frequency. Once the infrared beam is broken, the GP1 input changes, thus, the PIC12F683 reacts by triggering the GP4 pin connected to the BS170 MOSFET that act as a switch of the relay. The relay switch is set to shut the door when triggered. A push button connected at GP3 pin of the PIC12F683 is used for reset.

This project has a simple concept; the trap is built on a box fitted for a rodent to enter. The bait is placed inside the box to lure the rodent in. A sensor will be triggered once the rodent is inside the box, then a single door will shut lock behind the captured rodent.
