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. Bluetooth Serial Device Linux' title='Bluetooth Serial Device Linux' />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. Updated 21. 07. 2017. There are many very similar Bluetooth modules available and sometimes it can be difficult finding out, not only which one you have, but also how. 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. Celestion Sr1 Manual on this page. Age Of Empires 2 Mods Game Of Thrones. Device Status Maintainer Where to find NetChip 2280 net2280 driver works at both high and full speeds requires PCI Main kernel source gadget api info. I wanted to build a simple 2 channel bluetooth remote switch box. The device had to. 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.
