When working on some projects you will definitely loose sense and track of time unless you have “Freelance Puncher”. Raphael tired of looking for convenient way of tracking time spent on his freelance projects so he built a PIC16LF1827 time tracker which looks like detonator… It has a single button which toggles timer. Couple seven segment LED displays indicate hours spent on a project and also there are seven smt LEDs that indicate quarter and hundreds of hours. So you can track really long projects with it. Time information is stored inside microcontrollers EEPROM memory. Its open source project build one and you’ll probably find more uses of it.
