4m 70Mhz antenni katolle

4Metri / 70MHz / RHA68 antenniviritys

Laitoin tossa 70Mhz autoantennin katolle kokeeksi.
Kokeilin radiolla 1W lähetysteholla kantoi todella pitkälle jotai 10km joka on tuolla taajudella älyttömän hyvä.
SWR oli
68MHz = 1
70MHz = 1.4
71MHz = vähän alle 2
Antennin olisi kuulunut lyhentää hieman. pituus on vähän yli 1m jousen kanssa.
Haastavinta oli saada toi johto katon läpi ja piti tinailla jatkokaapeli siihen…
Täytyy viellä käydä pistääs 4 ruuvia tuohon peltiin jotta se ei lennä tuulen mukana.

Tällä hetkellä antenni on liitetty ohjelmistovastaanottimeeseen.


Canon 2900 working on linux

Getting a canon lbp 2900 working on linux in 2018

After a lot googling I found the printer should work fine on Linux, but it is a PAIN TO GET WORKING!

So what i have here is a ubuntu 18.04 LTS version
$ cat /etc/lsb-release

First, I got the drivers from canon:

tar -zxvf linux-capt-drv-v271-uken.tar.gz
cd linux-capt-drv-v271-uken/64-bit_Driver/Debian
sudo dpkg -i cndrvcups-common_3.21-1_amd64.deb
sudo dpkg -i cndrvcups-capt_2.71-1_amd64.deb

Be aware, use your own filenames the versions are newer ones so change new version numbers there what you downloaded.

install the driver:

sudo /usr/sbin/lpadmin -p LBP2900 -m CNCUPSLBP2900CAPTK.ppd -v ccp://localhost:59787

sudo /usr/sbin/ccpdadmin -p LBP2900 -o /dev/usb/lp0   #BE Sure replace the lp0 with your printerport do ls /dev/usb mine was lp1!!!

sudo /etc/init.d/ccpd start

now the driver is installed and daemon started it still not work, it will do an error ccp send_data error, exit
the reason for this error is because there is missing 32bit libs, and there is very little information about this problem, you will install libs:

sudo dpkg –add-architecture i386
sudo apt-get update
sudo apt-get install libatk1.0-0:i386 libcairo2:i386 libgtk2.0-0:i386 libpango1.0-0:i386 libstdc++6:i386 libxml2:i386 libpopt0:i386

After installation you need to restart all services:

riku@mythtv2:~$ sudo killall ccpd
riku@mythtv2:~$ sudo systemctl restart cups
riku@mythtv2:~$ sudo /etc/init.d/ccpd start

Now you go into your cups webpage and print test page. be aware you need edit cups.conf to allow your IP if using over a network.

Getting automated WiFi AP working on NanoHOTSpot / pi-star with 8188eu device

EDIT! Pi-star has on latest image autoap support, use this script only if you have 8188eu wifi device.

Recently someone asked on Facebook about automated ap, I was surprised how people are not aware the system is Linux and there can basically do everything if have knowledge.

I have done this scripts what can be installed on pi-star by only one command!

1. You log in to NanoHotspot (or mmdvmpistar device)

2. then type the command:  wget -O - | bash


Something good to know

Basically, the script works right away after reboot, no need config anything.
Default ssid is pistar and unencrypted wifi, you can set password by editing /home/pi-star/hostapd.conf on your home directory.
There is an existing firewall on pi-star, /etc/firewall.rules
The hotspot can be used as wifi-router if use an LTE/4G Dongle.
Scripts will only execute you don’t have a range for any known WiFI.
This is only a tool to help lazy people. don’t expect to bring a miracle to your hotspot 🙂

Here is the video how to install:
