➔ Selfmade ICOM OPC-599

Published: Thursday, May 22, 2014 | 2 minute read

The connection of a soundcard interface to my IC-706 MK2G radio required an adapter that is available from ICOM as OPC-599. That is a simple breakout cable from a 13-pin ACC connector on the IC-706 MK2G to an 8-pin ACC1 and a 7-pin ACC2 connector that are normally used on the larger (stationary) HF transceivers. This original accessorie is available for just 63€. That price forced the decision to make that myself.

➔ ICOM IC-92 Pinout

Published: Friday, Apr 4, 2014 | 2 minute read

The ICOM IC-92 radio comes with a waterproof connector for external mike and speaker. The connector itself is proprietary item that I could not find as an individual item to buy. As I made a custom headset and PTT button circuit myself I needed to connect to this jack on the IC-92. The programming cable is not suitable here because only 3 wires for programming are attached on the connectors. Buying (another) external microphone HM-175GPS was not taken into consideration due to the price.

➔ Firmware Update for Chipdrive Pinpad

Published: Thursday, Apr 3, 2014 | 2 minute read

For testing smartcard encryption and authentication I got myself a smartcard reader with built-in pinpad. It is a Chipdrive Pinpad or SPR-532. My OpenPGP smartcard V2 is already working in the smartcard reader in my notebook and in the Gemalto USB Shell Token V2. After fiddling around with different agents and disabling the Gnome stuff the reader was basically working. ssh-add -l showed my authentication key. But a login with that 4096Bit RSA key did not work.

➔ Fli4l on APU1C

Published: Monday, Mar 31, 2014 | 2 minute read

A few days ago my replacement board for the Alix 2D13 arrived. It is a PC Engines APU1C Board with an AMD G series CPU with two cores and 64Bit support. Onboard is an mSATA port which I connected a 16GB flash drive to as well as 2GB RAM, three LAN ports with 1GBit/s speed and an USB card reader. The size is the same as the 2D13 (6” x 6”).

➔ Gnupg with Smartcard on Ubuntu 13.10

Published: Sunday, Mar 23, 2014 | 5 minute read

A few days ago I switched my PGP key to 4096bit in order to increase the security level a bit ;-). That also reminded me of my Notebook (Dell Latitude E4300) having a built-in smart card reader. So why not combine these two and further increase security?! The smart card reader of the Dell Latitude E4300 is a BCM5880 by Broadcom with vendor id 0x0a5c and product id 0x5801 (a product id of 0x5800 seems also be available and is presumably the version without the fingerprint reader).

➔ Alix 2D13 speaker

Published: Thursday, Mar 20, 2014 | 2 minute read

Have you ever been wondering, why the Alix 2D13 never made any sound? Then yours was probably also shipped without the small piezo buzzer populated. It seems like all the 2D13s were practically fully equiped with the exception of this small device. The photo shows the area where the component BU1 should be mounted but never was. All the rest (driver etc.) is present. So solving this problem implies soldering just a suitable piezo buzzer here.

➔ Speedport 300 HS Console

Published: Tuesday, Mar 18, 2014 | 3 minute read

On various sources on the internet I found information that the VDSL modem that I use at home is driven by a Linux system. The device is called Speedport 300 HS and is origiginally manufactured by Sphairon. For various purposes I was seeking a (serial) console access to the device. In the end I wanted to peek on the physical parameters of the (V)DSL connection and let these by documented by the dsltool plugin for fli4l routers.

➔ New GPG Key

Published: Sunday, Mar 16, 2014 | 1 minute read

Dear folks, my OpenPGP key has been used for 11 years. Time to keep up with the latest security issues. I replaced my old 1024bit DSA key with a new 4096bit RSA key. If you signed my old key with the ID 0xAC7E90D0 I ask you to take a look at my transition statement. If you agree feel free to sign my new key. All further secure communication should involve the new key.

➔ Raspberry Pi LAN IR Remote

Published: Sunday, Jan 19, 2014 | 4 minute read

A few month ago I ordered a Raspberry Pi and played with it extensively on the OHM2013 hackers camp during summer 2013. The final project was a LIRC infrared remote control that is controllable using an Android mobile device with the app AMOTE Pro. And because the device should be placed a little away from the hifi console it needed PoE power supply to save an extension cord. After evaluation of a few selfmade options that were not compatible with 802.

➔ Fli4l on Alix 2D13 with large CF cards

Published: Wednesday, Mar 21, 2012 | 7 minute read

This information is outdated. See [1] If you have problems with installing fli4l on a large Compact Flash card the following information might be useful for you. I encountered the problem when I tried to install fli4l on a 2GB Compact Flash card. The mkfli4l.sh script installed the syslinux bootloader in the Master Boot Record (MBR) of the CF card. The subsequent attempt to boot the CF card failed because the syslinux bootloader could not boot the linux system.
