USB Pic Programmer This post is dedicated to anyone who wants to program a PIC (microchip) device via USB. While browsing the web for ready-to-use projects, I found a nice project called Open Programmer, which has several schematics, PCBs, and open source code. Source link: http://openprog.altervista.org/OP_ita.html. What bothered me was the need to install a …
Simple BFO metal detector BFO metal detector uses two generators. One generator uses a search coil, the second a smaller coil that is used to pattern the signal. By tuning the two coils so that their frequencies nearly match, the difference between the two frequencies begins to be heard through the speaker. The sound frequency …
Clone Pi AVR Metal Detector As the warm weather approaches, I decided to make this, a little more serious than the old AVT metal detector (MD). Advantages – LCD, settings can be changed, no expensive parts, more stable (than AVT) at low temperatures, easy adjustment, reaches decent depth, shows battery voltage and turns off when …
Metal detector on AVR microcontroller Since ancient times, people have been attracted by devices for searching for hidden metal objects. The reasons for this interest are varied. Builders are interested in the location of metal reinforcement in the walls, treasure hunters dream of finding a jug of gold coins in the ruins of an old …
How to program microcontrollers for Zabava-m1 r Zabava-m1 Zabava-m1 Zabava-m1 I program microcontrollers Zabava-m1 using the Algorithm Builder program and a programmer, the circuit diagram of which is present in the help system of this program. I take power for the microcontroller from the “crown” through the 78L05 stabilizer, be sure to …
Installation of parts and assembly of a homemade metal detector Zabava-m1 Installation of parts The parts are mounted on a piece of single-sided breadboard according to the diagram. The board size is selected based on the case size. The leads from the case of the R8 resistor are significantly larger than the holes in the …
Making a sensor for a homemade metal detector Zabava-m1 Making a coil The coil is wound on an oval mandrel glued from corrugated cardboard. Every ten turns are coated with epoxy resin, there are 50 turns in the coil in total, the wire diameter is 0.3 – 0.5 mm. The length of the coil is …
Homemade metal detector Zabava-m1 This article describes the manufacture of the Zabava-m1 metal detector with your own hands. The main difference from Zabava is the location of the working generator next to the coil in the sensor, made of epoxy resin. This location allowed the connecting cable to be removed from the generator and thereby …
Universal active Charger 4S The small Universal active Charger 4S module will be useful in building battery packs for portable devices. Because it works actively, excess energy is stored in inductance and transferred from a higher voltage cell to a lower voltage cell. Basic parameters: works actively, excess energy is not lost as heat, adapted …
GMR Board Introduction The full name of GMR board is General Robot Expansion Board, which is an integrated circuit board designed specifically for the Home Robot Platform (HCR). GMR Board Introduction Three microprocessors (single-chip computers) need to be inserted into this integrated board: two Arduino Nanos and one Arduino Mega ADK. The three processors have been connected …
