Metal detector chance (Chance) with their own hands
After assembling the metal detector ClonePi-W , I dug several hundred kg of scrap metal. Soon I wanted to find a real treasure . But do it without a metal detector that would distinguish metal sooooo hard. C ClonePI W I had to dig wherever squeaks and it exhausting . After searching the internet I settled on md Chance. Since it was manufactured by the same author INTO clone and is a kind of continuation of the series of devices clone 's website Chance . In the metal detector prisudstvuet selection for metals ( ie it can distinguish between nintendo and non-ferrous metal ) , the appliance has a function of discrimination . Scheme instrument :
Scheme of control buttons :
In order to collect this miracle of technology we need the following details:
- Microchips
- Adjustable Zener
- TL431 - 1 pc
- Linear voltage regulator
- 78l05 - 1 pc
- Quartz
- 11,0592 MHz - 1 pc
- Diodes
- Transistors
- Ceramic Capacitors
- Electrolytic condensers
- 10 mkf x 16v - 1 pc
- 100 mkf x 16v - 3 pc
- 220 mkf x 16v - 2 pc
- 1000 mkf x 16v - 1 pc
- 2200 mkf x 16v - 1 pc
- Resistors
- Buttons
- SWT5 - 6 pcs
- choke
- 220 mH - 1 pc
- LCD display 16x2. I used WH1602B. Conclusion on the LCD RW need to solder to the negative supply.
Take Circuits and solder as shown on the PCB, we get ready to board
Manufacturers sensor : To the sensor is not subject to special requirements in the area of 300-400 inductance microHenry resistance 1.3 - 2 ohms . I used a 25cm diameter ring 27 turns wire 0,67-0,8 mm, the sensor is also made as to the author's website
Device on both worked fine . Firmware microns Chance:
To flash microcontroller programmer can use the simple interface of c com five wires or if there is no com port to collect Usb programmer AVR910 usb .
Fyuz bits microcontroller must be bound as follows:
Everything you need for zborki device stored in the archive chance.zip .

- johnd говорит:можливо в вас є більш розгорнута схема приладу? абож хоча б зєднана,а не просто позначена?
- Radiolis говорит:На схеме присутствует кварц 11,0592 MHz, а Вы предлагаете купить на 12 МГц, влияет ли это на схему, нужна ли перенастройка на кварц?
- Александр говорит:во сколько обошлось построения прибора? себестоимость.
- Admin говорит:посчитайте по деталям
- Борис говорит:Прошивку в Atmega8 влил через продукт (USBISP AVR USB ISP USB ASP ATMEGA8) c avrdude, а вот fuse выставил как на картинке запрограммировал а чтение Error ошибка! Почему так? Собирать USBasp своими руками, или без команды для прошивки флеш из avrdude:не получится?
