-===== The pi as its own access point =====
-==== Overview ====
-Configuring the pi this way has the benefit of never having to seek out its ip address. Just connect to the pi's network and you have access to the machine.  That is the major PRO of this set up, but there are some cons:
-  * Connecting the PI loses your own internet access unless you bridge the pi to the local network
-  * FRC robots are not allowed to have hot spots on them
-  * Multiple PIs in the house will conflict unless you have a system for unique networks
-We are going to solve these cons later but lets just get the pi up and running as an access point.
-==== Install Necessary Services ====
-  sudo apt-get install dnsmasq
-  sudo apt-get install hostapd
-Make sure the new services are not running
-  sudo systemctl stop dnsmasq
-  sudo systemctl stop hostapd
-==== Configure Static IP with a 24 network ====
- Now we pick a network that the PI will host. I am choosing 192.168.3.x as our network.  That way someone may get the address 192.168.3.14 which has the value of pi in it.
-Now put the following at the end **/etc/dhcpcd.conf**
-  interface wlan0
-    static ip_address=192.168.3.1/24
-Restart dhcpcd
-  sudo service dhcpcd restart
-==== Configure DHCP ====
-  sudo mv /etc/dnsmasq.conf /etc/dnsmasq.conf.orig
-  sudo emacs /etc/dnsmasq.conf
-and add the following
-  interface=wlan0      # Use the require wireless interface - usually wlan0
-    dhcp-range=192.168.3.2,192.168.3.50,255.255.255.0,24h
-==== Configure Wireless Access Point ====
-Edit
-  sudo emacs /etc/hostapd/hostapd.conf
-and put
-  interface=wlan0
-  driver=nl80211
-  ssid=raspberry
-  hw_mode=g
-  channel=7
-  wmm_enabled=0
-  macaddr_acl=0
-  auth_algs=1
-  ignore_broadcast_ssid=0
-  wpa=2
-  wpa_passphrase=robotfun
-  wpa_key_mgmt=WPA-PSK
-  wpa_pairwise=TKIP
-  rsn_pairwise=CCMP
-Now edit
-  sudo emacs /etc/default/hostapd
-and set **DAEMON_CONF="/etc/hostapd/hostapd.conf"**
-==== Start up the Services ====
-  sudo rfkill unblock 0
-  sudo systemctl unmask hostapd
-  sudo systemctl enable hostapd
-  sudo systemctl start hostapd
-  sudo systemctl start dnsmasq
-==== Adjust Routing ====
-First uncomment **net.ipv4.ip_forward=1** in /etc/sysctl.conf
-** Doing the below, but I dont like it. Need a solution that does not use rc.local **
-Add a masquerade and save it
-  sudo iptables -t nat -A  POSTROUTING -o eth0 -j MASQUERADE
-  sudo sh -c "iptables-save > /etc/iptables.ipv4.nat"
-add to rc.local
-  iptables-restore < /etc/iptables.ipv4.nat
