Re: Screenly OSE -- Digital Signage for the Raspberry Pi

Hi guys, I am using Screenly OSE on Raspberry Pi and everything is great except the overscan issue. I have black border around pictures and web pages. I know what the issue is but have no idea how to fix it. I installed the Screenly OSE custom image and also have no idea how to access Raspbian conso...

Re: Using 74HC595 shift registers

Yeah finally. It works, but why? What is the problem with 5V? With 3.3V it's not bright.

Re: Using 74HC595 shift registers

Thank you for replies. But it still doesn't work. The problem is that 9th pin(first pin of the second register) gets same value of 8th pin of the first one. When I am setting first 8 pins high 9th also turns on. I've checked all connections hundred times but still can not understand what is the prob...

Re: Using 74HC595 shift registers

When I am pushing 16 bits together it doesn't work too. I just found that the problem is that 8th 9th pins run together. But why are you converting decimal to binary in your code. I've seen a couple of codes for Pi and shuft registerd and they did the same but I can't understand why. Why every time ...

Using 74HC595 shift registers

Hi everyone. I am trying to run two 74HC595 shift registers but they don't work correctly. I wrote a simple code just to figure out how they work but when I am giving HIGH value to the first shift register's 8 pins, 9th pin(first pin of the second shift register) also lights (I connected them to the...

Wireless controlled Pi

Hi I am trying to find the best way for my Pi's wireless control. I know that I can ssh, but it is only possible if Pi and computer are connected to the same network. But what if I want to run my Pi in the street where is no any WiFi ? I also know that it's possible to make a wifi router from the pi...

Re: Raspberry Pi LED Cube

Hi, Standard practice would be to use a separate 5v supply to power your cube, but the answer depends on how much current will your 'cube' require - if it's only 2 x 2 x 2 then it may work.... Texy For example if it will be 8x8x8 its gonna be over 600mA. I just wanna know is it possible to fo with ...

Raspberry Pi LED Cube

Hi everyone I am new with electronics and have a question about Pi's 5V pin. I am trying to make a LED cube and don't understand if I can use that pin to light my LEDs. I know that GPIO pins give 3.3V and secure current for them is 50mA. But what about 5V pin? How much is the max current for it? Tha...
