Runtime Counter v. 2.0

thingiverse

Uptime counter v 2.0 This is a remake of B-labz Runtime counter v1.0 witch was made for use with FM25L16B Fram chip. The purpose of this project is to make a Runtime counter for your machines like a 3D-printer or Laser module on a CNC machine or whatever kind of working time you wish to count and save. The power comes from a 6-24V pin of one of the machines, this is converted by the mini 360 stepdown buck converter to 5.5V for the microcontroller (connect at RAW pin) , other components are powered by the VCC pin of the Pro Mini. The advantage of the Fram is that it keeps the saved data even when there is no power to it. And will do this for about 10 billions times. When the power returns it starts where it stopped before, so no loss of time even by a power failure. What is changed: - The Fram FM25L16B-GTR is replaced by an Adafruit breakout board with a MB85RC256V chip. This requires a new adapted Arduino code. - The wiring is now placed on a secondary print that will hold all parts and the micro controller and Fram are placed in female headers on the print. In this case you can change those components for update or other use in the future. - The display is via I2C protocol and a 4 pin JST-XH wire connected to be flexible for placement. - The Mini 360 gets its power via a DC jack plug or by a screw connector, both are parallel connected. - An optional reset button is added for a reset of the Fram memory (after 3 seconds hold it reset the time to zero). - A new code is written based on the old one. Libraries used for the arduino pro mini are: Fram library used:              FRAM_I2C ( https://github.com/RobTillaart/FRAM_I2C ) Oled library used:               U8g2_Arduino ( https://github.com/olikraus/U8g2_Arduino ) Appendixes supplied: Arduino source code:        Runtimer_code.ino Print layout in Word: Dimensions of print: 42 x 62mm Hardware: - Arduino Pro Mini 5V version ( https://aliexpress.com/item/1005002995142159.html ) - Mini 360 DC-DC Buck Converter ( https://aliexpress.com/item/1005001505367325.html ) - 0.91 "Inch Oled Display ( https://nl.aliexpress.com/item/1005003081777701.html ) - Fram Breakout Board ( https://nl.aliexpress.com/item/1005003077716200.html ) - FT232RL FT232 Ftdi Usb ( https://nl.aliexpress.com/item/32460118879.html ) Interface needed to send the program code from the computer (usb) to the Pro Mini (serial) - Female and Male headers, DC-jack Female print mounted plug, Screw terminal, 10K Ohm resistor, print mount tact switch, a JST-XH print mounted 4 pin terminal and 2 Female 4 pin JS-XH Female plugs (for display). A standalone display box is added and can be used to place it near your machine. The first part is the housing for the print. The second part is the lid with the display (this is with double-sided tape mount). This unit is also addad to the Laser Control box on: https://www.printables.com/model/144189-stepcraft-style-neje-laser-control-box
