Raspberry pi zero.

Image
Instead of getting the rpi zero w, I will just add a usb female to my existing pi for the time being.Have lots of leftover cables for the cause.. Can always plug in a wifi or bluetooth module.   Various notes: Simplest configuration to connect to an unsecured wireless router knowing it;s essid: #linux auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wireless-essid router-essid  Improvisational solder less header pin for the rpi zero Original pi zero fully decked out. with bluetooth, wired m and wireless. Basic setup ----------------- install jessie os do updates install vim mc Wifi ------ Check Ethernet & Wifi Before continuing make sure the Ethernet cable is connected in and you can ping out from the Pi: ping 8.8.8.8 You will also want to set up your WiFi dongle. runsudo shutdown -h now and then plug in the WiFi module when the Pi is off so you don't ca...

What's on the network?

Image
Our goal here to see what is live on the network and how possibly vulnerable those machines are. Might be interesting to use with a wifi network. First lets get the live systems at the moment. You will need to change your code depending on your network, alive.sh [code]  #!/bin/bash rm goodips is_alive_ping() {   ping -c 1 $1 > /dev/null   [ $? -eq 0 ] && echo $i >> goodips } for i in 192.168.1.{1..255} do is_alive_ping $i & disown done [/code] Generated goodips file: 192.168.1.1 192.168.1.32 192.168.1.99 192.168.1.126 Then we can run a sort of network scanner. scannet.sh [code] datafile="goodips" a=1 m="not done" while read line do fdata[$a]=$line echo $line         let a=a+1        for p in {1..1023};        do        (echo >/dev/tcp/$line/$p) >/dev/null 2>&1 && e...

The internet.

If you liked the British comedy known as the "IT Crowd" then you might like to make this box. How it should work. External wifi host > wireless access point > wifi router > clients.  Inside the box = wireless access point > wifi router

Touchpad megaphone update.

Image
A while back I did a pvc megaphone add on for the Nexus 7. Now there is a newer version that is more stable. Because of the acoustics, it works really well in the bathroom. for some reason. Basically you seal up the end that will be away from you. ------------- Tried to use the famous Kipkay's method for a sort of megaphone for the pad. Not stable enough. Used tees instead of right angles. Also sealed off the back side of the tees to concentrate sound.

Let's get wired!

Image
Almost but not quite.  Had to replace the ethernet cable from the bridge (aka modem) to the network router/switch.  An ethernet cable looks like a telephone cable but twice or so as big, Back to the cable.  If you moved the cable the connection would fail. Not acceptable. Fortunately, had the tools and parts to repair the situation.  Many places use wifi, but there are a lot of business establishments that do not allow wifi for security reasons.  Since most tablets require the internet to be fully useful so that turns the units into bricks per se. What do you do?  You can now get adapters to connect touchpads to a hard wired old fashion network.  Usually consists of a usb connection sometimes known as an On-The-Go or OTG cable and then attaching the ethernet adapter. Of course you still need that cable to connect to the network. Where do you get the cable? If you are at a business establishment, they probably have a spare. Looks better if you already h...

New wifi networking

Image
There is a new way of wifi networking that will allow you to have wireless nodes as a network backbone to replace a repeater network.The mesh networking has become popular in Austin, Texas and is spreading like wildfire. Another way people can become their own isp.  For example ,say you have several houses or homes that you want to connect. You will not have to run any cabling between the units. All you need is a router that can run the Hsmm-mesh (tm) firmware. The network is a variation on ham packet radio. The original intention was to have a free network where anyone can become a node. You can do a little specialization if you want it to be at least a little bit private via the ssid. Several homes or locations do not have to be next to each other, but the participating units have to have standard routers that have the hsmm-mesh software installed.  You can tie the routers together, by using traditional repeaters, but if the main router goes down, so does the network. ...

Super antenna cheap.

Image
One of my side hobbies is to make foil based equivalents of traditional antennas. This is my latest prototype of the Gray-Hoverman antenna. Just $5 dollars in materials. It is also almost light as a feather. My next goal is to step it up a bit with commercial antenna clone. Probably do this one with coat hangers. Looking for the specs.

Homemade antennas

Whether it be for commercial radio, ham radio, TV, or even wifi people seem to love antennas. here are a few links to some of the antennas I have run into. My latest home made wifi antenna from someone else's design that is suppose to reach several miles! Still need to get the cable for the antenna interface.

We also use the traditional coat hanger antenna also. (Left hand corner of picture.)
