Re: 1602A LCD Upside down (wrong solder)

there are eight custom characters you can redefine (see e.g. https://omerk.github.io/lcdchargen/ or http://www.quinapalus.com/hd44780udg.html ) so if it is just for temperature and ip adddres you might be lucky to not use all 10 numbers at once :-) But resoldering seems easier :-) Or you can make b...

1602A LCD Upside down (wrong solder)

Hi, My current project is to display IP address and RPi's temperature on the 1602A LCD screen. It goes well and everything work just fine BUT due to my wrong soldering, the character displayed in an upside down manner. By any chance could i rotate the lcd display or anything else to do on the softwa...

Re: Selfmade Case with dynamic-PWM driven Fan

Could I know did you use any resistor? in my case im using a 5v 0.2A 3cmx3cm fan, could I use the same code above? lastly could also recommend any transistor that suits this project?

Inquiries about fan ( for learning purpose)

First thing first, I know that RPi doesn't need a fan, it is only for my learning purposes. So this is how it start, I recently bought a RPi2, in order to protect it (I break stuff always) I bought a cool looking case and it come with heat sinks and a 5v 0.2A 3cmx3cm fan. My question is, how could I...

This will log the date and the cpu temperature to /home/pi/cpu_temp.log every times that you run that line. date | tr '\n' '\t' >> /home/pi/cpu_temp.log ; vcgencmd measure_temp| tr -d "temp=" | tr -d "'C" >> /home/pi/cpu_temp.log Just put it into the crontab for every minutes. I...
