If you’ve ever wanted high quality sound from the Raspberry Pi, look no further than this High End Audio Bundle from Allo.com.
High End Audio Bundle
This bundle includes the following boards:

There’s also an option to include a 3A 5V power supply with the bundle.

This bundle plugs directly onto the Raspberry Pi like any other hat, and then you can set the audio as per normal with Alsamixer.
With the Kali hat plugged in, you can power the Pi from the Kali hat rather than needing another power supply. The Kali also powers the Piano DAC.

The Piano DAC can be setup in a 2.0, 2.1, or a 2.2 setup with crossover settings in the GUI. It uses dual PCM5142 DACs with integrated DSP, and comes preset as a 2.1 setup, but can be reconfigured via the PurePath software.

The last part of the bundle is the Volt Amp which uses a TPA3118 chip. It has 4 output filters, 4 EMI Snubbers, 4 bootstrap capacitors and gain setting components.

This whole bundle can be purchased from the Allo Website and for a limited amount of time, you can get a 5% discount by using the coupon code SIRLAGZ5

I’ve had my Toshiba Satellite L750D laptop for quite a few years and when I first had it, the battery would show up in the battery meter in Ubuntu. Over the years and after a few Ubuntu upgrades, the battery just disappeared. The system wouldn’t detect the battery at all anymore. I tried all sorts of things to get it to discover the battery, reinserting, restarting, reinstalling, re-everything-else too, but it just wouldn’t show up.

I bought this camera the same time I bought the OfficeOne IP900 cameras, but never got around to using this until now. The camera seems to be fairly easy to setup. Plug it in and it will get an IP address via DHCP. The supplied software CD contains some management software which runs on Windows, but since I’m not a Windows user, I haven’t tried it out yet.

I finally set up my NodePhone service on my FreePBX/Asterisk server after telling myself to do it for a while.
There wasn’t a lot of concrete information out there but through lots of Googling I figured out enough to set it up via the Web GUI.

The following settings are the ones I used to set up the trunk –

Trunk Name: Internode
Outbound Caller ID: Your Internode DID Number

Everything between Outbound CallerID and the Outgoing Settings can be left as default.

Under Outgoing Settings, I’ve used the following settings, however since my Asterisk server is behind a NAT, I’ve set nat=yes on both Peer details and User Details. If your Asterisk server isn’t behind a NAT, you shouldn’t need those settings.


Trunk Name: nodephone

PEER Details
context=from-trunk
type=peer
username=[YOUR NUMBER]
fromuser=[YOUR NUMBER]
secret=[YOUR SECRET]
fromdomain=sip.internode.on.net
host=sip.internode.on.net
dtmfmode=rfc2833
disallow=all
allow=alaw&ulaw
nat=yes
insecure=very

For Incoming settings:

User Context: [YOUR NUMBER]

User Details:
context=from-trunk
host=sip.internode.on.net
secret=[YOUR SECRET]
type=peer
username=[YOUR NUMBER]
insecure=invite
nat=yes

For the Registration:
Register String: [YOUR NUMBER]:[YOUR PASSWORD]@sip.internode.on.net/[YOUR NUMBER]

These settings should get your trunk up and running.

I wanted to monitor the ntpd and python processes on one of my servers so that I would know if one of them went down.
I already had Zabbix and SNMP monitoring setup on this server so decided to have a play around with SNMP Process monitoring.
