Reactivate old RasPi

As my first Raspberry Pi catched some dust I found a new project involving it.
Researching current procedures regarding backup old image and add new image to the SD Card, here it is:

Backup

  • Putting the SD Card in my reader in my Mac
  • Utilities > Disk Utility
  • File > New Image from boot
  • Choose as type CD/DVD image and save it

New Image

The really cool and minimalistic tool Etcher is suggested by the RasPi homepage.
I chose the current Raspbian 9 to be put on the SD Card by Etcher.

Etcher in use

Once the copy/install process was finished I opened a terminal session, navigated to /Volumes/boot and used touch ssh.

This will enable ssh on the RasPi, directly enabling it to be contacted by a terminal session instead of putting a usb keyboard on it.

  • User: pi
  • Password: raspberry

Any changes can be done with sudo rasps-config – especially password and network name of system

Now the old RasPi can be used again, this time without extra ac plug but on the new Bestek Steckdosenturm.

Audio Update: Testrun

After testing with multiple devices we have some more answers.

With my Mac I use the included tool Audio MIDI Setup to set the output format to an appropriate value (eg. 32bit, 384 kHz). Interestingly the Audinst device had the most sophisticated settings:

Headphones: beyerdynamic DT 1770 PRO

DACs:

  • Grace m9XX: still sounds awesome, current drop: massdrop: Grace m9XX
  • Aune X1s: right behind the Grace m9XX for half the price
  • Audinst HUD-DX1: a bit behind Aune X1s

In general the Grace m9XX just has the bass to keep you pushed and a magic clarity with which every song sounds different than before without it. Also the dynamic range is just more present and larger.

Software: Pine Player

If you want to go for high quality data music on a Mac, use the Pine player which is available for free on the app store.

It allows to play existing digital audio forms such as MP3, FLAC, APE, AAC, M4A, WAV, AIFF, OGG, WMA, DSD etc. and it also has a strong playing capability for listening to CUE files in the most convenient way.

Especially FLAC and DSD are iteresting for the best possible output on a DAC/AMP combo for headphones.

Example hires files are to be found at 2L.no so you can check them with the Pine player on a Mac with external DAC.

Testrun for workplace environment: Grace m9XX

Tested the Grace m9XX this week – just wow.

I used it with the superb beyerdynamic DT 1770 PRO, successor of the famous 770 PRO and plug it into the Grace m9XX.

The Grace m9XX is connected via USB to my Mac, running Spotify with High Quality Streaming activated.

Sadly, the Massdrop x Grace Design m9XX is only build in small ‘drops’ so I’m waiting for the next one to get this great little device.

Cube update: Crucial MX300

Trotz des Vorsatzes, zu Black Friday nichts zu bestellen, habe ich ein um 60€ günstigeres Angebot genutzt, um den Cube Server mit Crucial MX300 SSDs je 750GB aufzurüsten.

Im bereits vorher gekauften Gehäuse ICY Dock MB996SP-6SB wird der Platz jetzt eng. Insgesamt passen 6x 2,5″ Platten in das 5 1/4″-Gehäuse. Wie schon die Samsung 850 EVO lassen sich die noch flacheren Crucials gut auf die Metallschinen schrauben und sitzen fest.

RAIDZ aus SSDs

Mit den neuen Crucials richte ich mir endlich ein RAIDZ aus SSDs ein und verschiebe die bestehenden VM Images direkt auf den schnellen Storage.

Lightroom editing with Midi: Behringer X-Touch Mini

To improve my Adobe Lightroom workflow I plan to use the Behringer X-Touch Mini to edit pictures faster and focusing on the tools in photo edit view.

Some reviewers suggest to use MIDI2LR, however I’m still with Lightroom 4. Let’s see if it works, otherwise the first good reason to go after current version 6.

Click if you want to buy Behringer X-Touch Mini at Amazon.

This post will be updated once I got the X-Touch Mini.

Büroequipment: Vergleich zweier günstiger USB-Mäuse: Amazon vs. Logitech

Die beiden Mäuse AmazonBasics und Logitech B100 sind bei uns im Einsatz. Durch den günstigen Preis sind die beiden Mäusesorten immer mit ein paar Stück im Schrank für den schnellen Austausch bereit.

AmazonBasics USB-Maus mit 3 Schaltflächen (schwarz):

  • Standardmaus, angerauhte Oberfläche, für große Hände etwas zu klein
  • Verrichtet klaglos ihren Dienst am Mac
  • Zeiger bewegt sich etwas schneller in Standardeinstellung

Logitech B100 Optical Business Mouse, schwarz

  • Standardmaus, glatte Oberfläche, für große Hände geeignet
  • Verrichtet klaglos ihren Dienst am Mac
  • Zeiger bewegt sich etwas langsamer in Standardeinstellung

Fazit: Logitech für große Hände, AmazonBasics macht wertigeren Eindruck.
