Nexus 5 batteribytte

Telefonen jeg bruker til android apps, som f.eks. WiGLE Wifi, har i det siste est ut og blitt tykkere. Den åpnet seg i den ene klipsen og lot seg ikke lukke. Etter en nærmere titt viste det seg at det er batteriet i min Nexus 5 er synderen. Da er det eneste sikre å bytte det. SparesLG.com ble sterkt anbefalt på nett, og jeg skjønner hvorfor. Batteriet ser på alle måter ut til å være original vare, produsert for ikke for lenge siden. Pris, frakt og leveringstid var helt kurant. Telefonen er også svært enkel å jobbe med. Batteriet sitter kun med noen få striper teip, og man trenger kun skru opp 6 skruer over et lite deksel.

Commodore 1581 build and repair log

Some years ago I bought a 1581 kit off eBay. The remaining bits after Commodore cannibalized 1581 drives to get floppy's for their Amiga computers. I acquired two Chinon FB-354 drives, but could not get the drive to work. After some years on the shelf I took some time to finally get it up and running. A friend printed me a new eject button for one of the drives, as it was missing it's button. Then I placed an order for a ZoomFloppy and a JiffyDOS ROM for the drive at Retro Innovations. The ZoomFloppy works great in Windows 10 after getting updated software and drivers. But I could not write disk images. The drive would not work in the C64 either. Giving drive not ready errors. Preparing a new disk did not produce the sounds it should, and the drive stopped spinning way to fast. So on to the troubleshooting.

C:\Program Files\opencbm>imgcopy.exe vandalismnews65.d81 10
[Warning] invalid imagetype for this drive type
[Warning] invalid imagetype for this drive type
[Fatal] invalid imagetype for this drive type

Running in verbose mode shows the drive is misdetected as a D80 drive. Possble due to the JiffyDOS ROM. Trying again with the parameter -d 1581 worked better.

After a quick Google I tried another disk, which I was almost certain should be good. NOS 3.5" MFD 135 TPI, Double Sided, Double Density, Japanese Media which my boss gave me. Got further, but still no cigar.

Trying to get the head to move

Strange. Google gave little results. So I pulled the drive apart and ran it naked. I noticed the drive head never moved. I cleaned the heads with isopropyl alcohol and jerked the rod and head movement mechanism. The grease was soft, but apparently the mechanism was stuck. I power cycled the floppy drive and tried again. And it worked!

NextGenTel IPTV with pfSense

To get the most out of my fiber connection I run my own pfSense router instead of the cheap one provided by my ISP. To get the TV signals through you will need to to some changes to your network configuration:
