There was not interesting projects. The last one was a battery backup switcher, it switches power source to battery when mains go down. Based on relay and transistor. Today project is not a big deal too I have a cheapo OBD II USB adapter and serial bluetooth module. As bluetooth module was not used anywhere for a long time I decided to hack OBD II USB adapter and make it Bluetooth instead of USB. Yea I know I can buy a cheap Bluetooth OBD II adapter, but I like DIY. So I opened the box and found PIC1. F4 mcu inside and FTDI2. RL UART to USB serial converter. Then I desoldered FTDI chip with usb crystal. My bluetooth serial module needs 3. I had to add 3. 3v regulator with couple of capacitors took 5v from 7. M0. 5 voltage regulator on pcb. OBD II box has 5 leds indicating rxtx from car and serial and power status, BT serial module can indicate its status with led too, so I drilled a little hole in the box top right under sticker and glued the led with hot glue. When I finally soldered this mess o wires to adapter pcb in place of FTDI chip I found that is does not work, not receiving or sending any data, but bluetooth pairing works and BT status led works as it should. Took a bit of time to solder FTDI chip and crystal back for debug. Find out that it works as USB ok but not bluetooth. Then I take a look where tx and rx connects to PIC mcu and you probably guess already, I connected BT module tx to PIC tx and thats wrong Changed wires and soldered them right to the PIC mcu legs, that works. Time run away and I leave FTDI chip on pcb. Thats it, works great with my Android phone even better than windows scanner apps under wine in Ubuntu.
