Electronic combination safe kit with variable resistor dial and onboard relay
This listing is for an electronic combination lock "Safe" kit. Using a variable resistor dial, you can choose different digits between 0-9 and enter in a code. The digital are displayed on a 7-segment display. Once you've entered in a code, the circuit will wait for the correct code to be entered. If you enter the correct code, an on-board relay turns on, and you can control AC devices. If you enter in the wrong code, a small piezo buzzer alarm sounds. There is so much more to be said about this kit. The above video demonstrates the functionality of the kit in full, talks about assembly instructions, as well as the schematic diagram of the kit. This video is your instructions. When you purchase this kit, you will receive the custom circuit board, and all of the components required to build the kit, minus three wires that are used to interface the kit with the variable resistor dial. We can also sell you this fully assembled and tested for a few dollars more. Watch the video! We developed this kit, so please don't hesitate in asking us any questions you may have.
This kit includes:
1) A Custom PCB (Printed circuit board).
2) All of the components required to build the kit.
3) Round the clock access to the instructional video =) We will send a piece of paper with a reminder of how to view the instructional video on our website.. Or... You can just come back to this listing and see it again here!
Kit Features:
1) An on board relay that can control 120VAC devices at a maximum of 1.5A
2) Programmable code entry on power-up
3) Timeout indicators when the user takes too long to enter in a code (See video)
4) LED, buzzer and 7-segment display indicators.
5) The video demonstrates functionality, gives assembly instructions, and talks about the schematic.
Requirements:
1) Power Supply: 7VDC - 25VDC (regulated to 5VDC on the board)
2) Basic soldering skills.
3) Attention to detail. Some kit assembly experience is helpful.
Applications:
Security systems
Door Locking devices
Use your imagination!
