Normally the ends of shoelaces are protected with plastic caps to prevent them from fraying, but they sometimes break and get loose. Once the ends of shoelaces start fraying, it is very hard to put them through the tiny holes of your shoes. This is an easy fix:
Get some glue, the right size of heat shrink tubing and a heat gun (or a lighter)
Put a little amount of glue on your finger and wet the ends of the fraying shoelaces with it.
Cut a suitable length of heat shrink tubing and shove it over the end of the fraying shoelace.
In the nineties I built a class A power amplifier based on an article in the November 1985 edition of the Dutch electronics magazine Radio Bulletin. In 2000 I reproduced the article on my web site and added photos and extra schematics for a stabilized power supply for the preamp stage. Although some of the components are probably not available and the original website is long gone (archived on the WayBackMachine), I found it useful to repost the Dutch article: Klasse A-versterker van 20 Watt
I am a huge fan of SomaFM. I Have been listening to this listener-supported, commercial-free Internet-only streaming music station for years.
I do no only use my xbmc on Raspberry Pi (OpenElec) to watch movies, I regularly listen to music as well. So how can we add the wonderful ambient, jazz, loungy or indie tunes of SomaFM to xbmc? A quick search pointed to https://github.com/nils-werner/xbmc-somafm, but my OpenELEC lacked the git command.
Reluctant to install git on OpenELEC just for this, I performed this workaround
I first installed git with the default package manager on my Linux Destop (Synaptic on Debian)
Every time Ubuntu updates installs a new Linux kernel, your VirtualBox is likely to be broken. I got these error when starting my virtual machine:
The virtual machine 'xxx' has terminated unexpectedly during startup with exit code 1.
Kernel driver not installed (rc=-1908)
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing
as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.
The Atten 858D Hot Air Rework Station is a very handy tool. Until now I have only used it for removing some SMT components and for heat shrink tubing. Check the EEVblog for an in depth review of the Atten 858D.
Like any cheap Chinese gear, you should open it before turning it on to make sure it is electrically safe. My unit did have a grounded heat element, but the case was not grounded. This was easily remedied by sanding down the paint on the inside of the case around the mounting holes of the transformer and then making an additional connection between the ground pin of the mains input and one of the mounting screws of the transformer. A quick continuity check confirmed this hack was a success.
This Atten hot air rework station has a very nice feature: when you put the element in the stand, the heating element turns off and the nozzle keeps blowing until the temperature drops below 100°C. Although I regularly knocked the handset down because my rework station was on the front of my desk, I hesitated to put it more in the back. The backdrop of my workspace is a wooden panel and it would not withstand the initial heat escaping from the rework station… Continue reading A heat shield for the Atten 858D hot air rework station→
