Most users who encounter this probably have an issue with the core storage volume; but for me the issue was that there were no local users able to unlock the disk. It took a while as there was not a a very helpful error or anything in the logs.
In my situation had deployed an image using DeployStudio which created the local admin user as a hidden user and was trying to get Profile Manager to work but kept getting stuck on the FileVault, none of the logs had anything useful in them, just things like
com.apple.preference.security.remoteservice CoreStorage conversion failed with mainError: -69886; detailError :0
The fix was to simply add a new local user and then enable it to unlock the disk.

I bought a little 2000L pool and it quickly built up a load of dust/dirt on the bottom of it and the cheap pump it came with didn’t seem to be doing much, So I looked at what I had in the garage and figured I could make my own pool cleaning system. I realized the gist of the crap was settling at the bottom so I made a quick ‘Vacuum Cleaner’ type arrangement with some PVC piping and tubing, a pump I use for brewing beer, and some odds and end I picked up from the hard ware store.
With any project I do it is important to have nice photo’s that are in focus and well lit. I occasionally dabble in stop motion and other film as well as just the projects you see on this site. Lighting is something I have always had difficulty with and never spent any time trying to resolve. Occasionally I use a work light but I find them annoying to set up and they get very hot and difficult to work with.

When home brewing beer its important to keep a constant and cool temperature. I like to aim for around 19 degrees C (66F) for ales. (references) and 4 degrees C for Lagers but in New Zealand the general yeasts sold or packaged with kits for lagers are really ‘lager style’ top fermenting (ale) yeasts; also I don’t have the budget or equipment to go for a lager style ferment anyway.
So I wanted to build something that would smooth out daily temperature variations and could potentially have some temperature management (eg peltiers in the summer, incandescent light bulbs in the winter) to assist in smooth and appropriate temperature management.

While I was waiting for some more sealant to dry on another project, I decided to finish up something I had been thinking about for a while: A motorcycle chain lubrication system. I dont like using the spray, or oiling it by hand with a rag much. So I built a system that you could attach to the bike, put some oil in, go for a ride to the end of the street and back then take it off again.
