I tried to install mencoder to make a timelapse video from a set of images but I get a strange error: pi@raspberrypi ~ $ sudo apt-get install mencoder Reading package lists...

Re: Jessie Q&A

The fim image viewer package seems to have gone missing from jessie, is this an oversight and will it be replaced or is there a reason for leaving it out? I use a bash script to take pictures, save them and then display them for 10 seconds before taking the next one. When the script is finished I c...

Re: Sept 2015 Scratch release

[Copied from blog comments at Tim's suggestion] This is all great news and the speed increases are very impressive. I have some queries about the motor control however. It looks as if this is only provided through one of the supported add-on boards? I have been using Simon’s ScratchGPIO for a good w...

Re: Take, save and display photo for 10s, repeat

The following script acquires an image using a 1 sec suppressed preview and takes about another second to save it. It then displays the image for 9 sceonds before going around again the value of 60 giving a 10 minute sequence. The {001..60} in the for command uses brace expansion to give leading zer...

Re: Take, save and display photo for 10s, repeat

Hi James Fim seems to be an improved version of fbi but it's a bit unfinished so I think I'll try fbi in parallel. I have got as far as writing a bash script that will capture an image, call fim to display it for a set number of seconds and then quit. I do indeed want to retain the images so my next...

OK, I have located and installed fim which seems to be the latest version of fbi and will work on this but I am new to bash scripting and would still appreciate any help.

Re: Take, save and display photo for 10s, repeat

Thanks James, that sounds like what I am looking for. I have tried acquiring images with no preview but didn't know how to display them. First question though, what is fbi and secondly, will I be able to take and save a succession of images with a script while displaying them at the same time? Colle...

Hi I have been asked by an artist to assist in projecting video of her while working on a drawing. She doesn't want continuous video but felt a series of images at say 10 second intervals would be good. The ideal would be to take a time-lapse series during the work (about 30 min) and display each on...

Re: What is the ideal Raspberry Pi CPU temperature range?

I have several Pis and one Chinese-made one ran up to 60C in a Pibow case with just medium overclocking and low load. It had wifi but I connect with ssh so it wasn't running hdmi. It runs at about 47C bare and I usually keep it on its side to allow better airflow. Maybe the one that's running hot ha...

Re: Redesigning the soldering iron!

My first iron was a 30W mains-powered one (which I still have). It would get too hot if left on for any length of time but took too long to warm up if unplugged. I came across an ingenious solution in an electronics mag of the time which was to get a mains plug with an on/off switch on it and solder...

I too have been having problems with the latest Raspbian using ssh and vnc to run pi's headless (with wifi). I can get a remote desktop running with vnc but after a few minutes the pi just freezes and the dongle goes off. I tried this with ethernet too and had the same problem - network dropped. I h...

Re: Can overclocking damage the pi?

I always set the speed / over clocking to medium in raspi-config. This runs at 700 when lightly loaded or idle but jumps to 900 when a load comes on. As James says, this is noticeable. This compromise gives the minimum effect of over clocking while providing better performance.
