Uncanny Movie

I just finished watching the movie Uncanny on Netflix.  It's a science fiction movie about a guy working on artificial intelligence.  He created an android and made it as lifelike as possible.  He calls himself an illusionist.  The android is incredibly lifelike and creepy.

This movie appeals to me as someone who is into robotics, AI, making, and science in general.  It's an intellectual thriller.  I enjoyed watching it and would like to watch it again.  The ending was a surprise but more because of how unlikely it seems when you think about how the android and the maker acted during the week.

I am left with feeling confused and a bit creeped out at the same time.

Setting up Multiple WAP Routers on a Home Network

I have a main WAP / router (Netgear WNDR3700v4) in my house that connects to the cable modem (Motorola Surfboard SB6141) and the outside world.  I also have a second WAP (Cisco RV220W) and a wired-only router (D-Link EBR-2310) on my home network that extend the network.  Only the main router provides DHCP functionality.  The other devices connect to the main router through a LAN port.  This works fine but the secondary devices do not connect to an NTP time server.  They also will not look for firmware upgrades.  Both of these functions go through the WAN port.  Since the WAN port is not used, the device will not automatically update its time nor firmware.

Today, I figured out how to fix that problem.  I found some good information at this web site.  Basically, the way to setup a secondary router on a home network is to give the WAN port a static IP address on the main network and put the LAN ports on a different network.  The LAN ports can give out IP addresses using DHCP.  The secondary router will use NAT to route traffic from the LAN ports to the WAN port.  The router thinks the WAN port is connected to the internet and will use it to connect to the NTP time servers.

It is a good idea to turn on the feature to return a ping on the WAN port on the secondary router.  Also, turn on remote management so you can get to the router from the home network.

My devices are configured like this.

Netgear (main router)

• WAN IP: DHCP from ISP
• LAN IP: 192.168.0.1
• DHCP: On

Cisco

• WAN IP: 192.168.0.1
• LAN IP: 192.168.1.1
• Remote management: 192.168.1.1:443
• DHCP: On

D-Link

• WAN IP: 192.168.0.11
• LAN IP: 192.168.2.1
• Remote management: 192.168.2.1:8080
• DHCP: On

Electric Toothbrush Storage

I have an electronic toothbrush.  There is no good way to store it.  The toothbrush is too big to fit in a normal toothbrush holder.  Having the toothbrush standup on the sink is not good because the water builds up on the bottom and creates slime.

I saw an article in a Family Handyman magazine about how to store an electronic toothbrush on a wall using a strip of metal and a magnet.  The article mentioned connecting a strip of metal to a wall, then using a neodymium magnet to attach to the metal.   The toothbrush simply clings to the magnet because it has metal in it.

I happen to have a bunch of neodymium magnets from computer hard drives in my stash of junk.  Those magnets are very strong and are attached to pieces of metal that have built-in mounting holes.  I attached one of those magnets to the wall in my bathroom using drywall screws.

One added benefit is that the magnet appears to charge the battery in the toothbrush.
