Hi all,
yesterday I received my second Makerbuino (I took the first one during last MakerFaire in Rome) and started asap to assemble it.
I arrived successfully to step 12: turning on Makerbuino, the screen showed my a message telling me to adjust the contrast, like the one published at step 23 (https://makerbuino.com/wp-content/uploads/2017/08/DSC05743_800x533.png). Of course, I couldn’t d oanything since still I hadn’t soldered the push button and all the other components of chapter #4.
Then, I continued with steps in chapter #4 but, at the end (step 23) only backlights work on the screen: no message, no text, no sound.
I tried with hard reset (turning off device, inserting sd card, pushing C button, turning device on again, releasing C button and waiting for more than 30 seconds). I also tried hard reset twice times in sequence.
The LiPo battery is charged.
It’s quite frustrating.
I’m not an expert in soldering but it doesn’t look as a too bad work.
Here is some shots of my work.
@albertgajsak, @f4egx, you were right, I forgot to solder that SD card data pin.
As soon as I soldered it, it worked!!
I successfully tested all the buttons, both potentiometers and sounds. Finally, exiting the setup page, I got the game screen
Then I just tried to browse across the different pages, looking at all the game icons before finishing touches (chapter #5).
But, again, after finishing to assemble also the case, my Makerbuino shows again only backlights .
I tried hard reset (with SD card inserted, of course) twice and finally I heard the sound of the mail page… without seeing anything on the screen. The same happens if I turn off and turn on again the device, I can only hear the sound… looking at the backlights.
It seems that the screen is not working properly (or there is some other weakness in soldering components).
Hi Albert,
yesterday I reheated joints both on LCD and SD Card.
As a result, the device started again to work for a while… then the same problem: no text or image on display, only sounds.
I wanted to test it a little bit, trying to understand if the problem was due to an unstable joint. I tested (by gaming) just putting the device on a desk, trrying to push buttons without too much strength and without moving the device: sometimes the display works, sometimes it doesn’t, withount any specific apparent cause. I also tested it (and the same was done by my son and my daughter) “shaking” it, putting the device in my pocket for a while and then turning it on again to play, etc: it lasted a lot without showing any problem, then again the display was blank…
Do you have any other idea before I send you back the device as you suggested?
I am experiencing the same problem. After step 12, I had the “adjust contrast” screen. I then continued soldering all the components. Now, at the final test, I only get the backlight of the display. Also, when turning on the Makerbuino, I get a chime sound on the headphones. Hard reset seems to work, after 30 seconds, I hear the startup chime again.
But still nothing on the display. @albertgajsak, do you have any suggestion what to try?
attached an image of the display, there seems to be a dark border on the top.
