Better, faster, stronger!
Hello Makers, in this post, the amazing DIY GoPro remote in it´s second version, with a backlit display and 3 buttons.
In this tutorial, you will read about all the steps, how to get to your own cheap and powerfull GoPro remote.
YOUTUBE VIDEO WILL FOLLOW SOON!
- PCB creation (printing / sawing / etching / drilling)
- Having fun
- Support me by following, thx!
Do you have all these parts at home?
- one sided PCB plate for etching
- safety glasses and gloves
- 50g sodium persulphate (N06CG)
- some pin headers
- 1x 6 pin OLED Display (GND, VCC, SCL, SDA, RST, D/C)
- 3x pushbuttons
- 1x ESP8266 ( I used the 07, but 12 should work aswell)
- 3 x 33kOhm SMD resistors
- 1x AMS1117 voltage regulator 3,3V
- 1x USB to TTL converter
- some jumpercables for programing
- soldering iron (if you dont own one, stop reading here, close this page )
- plastic vessel for etching
- a piece of a glossy magazine
- Laminator or Iron
- little boards saw
- 0.3 mm PCB drill
- drilling machine with stand
- spirit or alcohol
- rough sponge
Print this PDF (ESPGOPRO_etch_copper_bottom) on a glossy piece of magazine – I have cut out a squere piece 10 x 10cm and taped it in the center of a sheet printerpaper.
Water the sponge with alcohol or spirit and scrub the copper layer of the PCB.
Cut out this printed (yes it is mirrored, it has to be!) only so etch template and tape it with the printed side down to the copper sided PCB.
You can now saw the needed piece of the PCB. What a mess. Puhhh.
Now heat up your laminator / iron and burn the laserprinted pigments onto the copper of PCB. I let it run through the laminator for 10 times at 125 °C.
5 minutes under the iron should be okay. But without steam!
Wash the paper off the PCB. It should look like this:
Put on the glasses and the gloves, if not: Do not keep going!
Fill in the vessel 100 ml of 50 °C warm water and give 20 g of sodium persulphate.
Place the printed PCB in the center of the vessel and swing it a little. This step took nearly 1 hour, to dissolve the not printed copper:
Wash the thoroughly under cold water:
Take the drilling machine and your thin drill and drill the holes for the Pinheaders of the OLED Display and the buttons. This where 18 holes. If you want – you can drill some holes for extra pin headers ( GPIO 0 to GND jumper, GND VCC and RX TX for programming.)
You must not drill the extra holes, you can solder some wires to the contacts, or put them to te down side of the PCB directly. I drilled them.
Study this picture at least 1 minute:
Route the top side parts, the OLED and the 4 buttons, through the holes and solder them.
Then take the 3 SMD Resistors and the AMS1117 Voltage regulator (4 points to solder, the heatsink, too!) and solder them, too.
Take the ESP8226, realize the orientation and solder the 16 contacts to the PCB.
Solder the pin headers of RX + TX, then VCC + GND and then GPIO 0 and GND.
For programming set up an Arduino IDE under this Tutorial: https://github.com/esp8266/Arduino
Short the GND and the GPIO 0 jumper, connect RX and TX to the USB TTL converter, realize the polarity and connect VVC to 5V+ and GND to the converter.
Use this code for burning:
Release notes: V 1.01 – 04.Jan.2016:
- middle button – starts the recording – a second push stops the recording
holding it down, means that the GoPro is recording while you hold the button – release it to stop.
- right button – activates the beep signal of the GoPro for finding it in devilish high grass (I lost my last GoPro) – pushing once = 1 beep, holding it down keeps beeping while you´re holding
- Display – Shows the status of the trigger (Recording, Standy)
the second row shows the mode and the battery level
the third the resolution ad the framerate
the last row shows how many minutes of recording can be done.
- left button – not programmed yet – will change the modes of the GoPro
(does anyone know how to change the SUB MODE ?)
Plug the USB Converter in and burn the code!
