Information: LXPanel Issue

Hi all, TLDR: Dont make backup copies of LXPanel panel files inside the panels directory. I wanted to notify the community of an unintended issue I discovered with LXPanel over the past few days. This is technically not a bug as LXPanel is doing exactly as it was intended to do. I recently created a...

Re: Static networking and Stretch

I have used the cmdline.txt option ip=xxx.xxx.xxx.xxx for a while now to set a static IP on several Pis It works but I dont think the ip parameter was designed in the way you are using it: This parameter tells the kernel how to configure IP addresses of devices and also how to set up the IP routing...

Re: Stretch | Not able to rename network interfaces any more

My first thoughts are that the default link file is being applied first: The first (in lexical order) of the link files that matches a given device is applied. Note that a default file 99-default.link is shipped by the system, any user-supplied .link should hence have a lexically earlier name to be ...

Re: Multi-channel home light controller

Hi Roy, As you state, there are a plethora of relay boards out there so recommending which one is best is impossible. All I would suggest you look out for is that the boards can switch UK supplies at 240V AC. If not then you risk fire/injury. I took a risk with mine and got them from ebay. Touch woo...

Re: GPIO output wire length limits?

Hmmm... with short cable RPI GPIO can supply a maximum of 16mA on a pin. The relay needs 3VDC 120mA (I am the one who mentioned coil current/voltage) Probably a pretty decent way to fry a GPIO pin (if the relay board does not have an opto isolator). Now if the relay board has an opto isolator on it...

Re: How to increase display brightness? and resolution

hdmi_boost may be what you need to fix brightness issues. hdmi_boost has no impact on the brightness. It only affects the level of the voltages, representing '1's and '0's, on the HDMI interface. Once those voltages are high enough that the '1's and '0's can be reliably distinguished from each othe...
