Padre went to Rome to run media for the Jesuits, and he needed some serious gear to make it work. From a Predator laptop to an SSD bonanza, a tricked out USB drive and an inexpensive 360-degree camera, he shows you the gear he brought on his "Roman Holiday."

The boys are back! After 6 weeks away, they ease back into the Know Space with a basic lighting project. Cranky Hippo takes the lead as they combine an Arduino Nano, a strip of WS2812s and some soldering know how to make a LED picture frame. Oh... and Padre is really sick.

We go over the history of beer, what it's made of, and what goes into brewing like a pro with Russell Tammany, and basic brewing with the Mr. Beer Kit!

We show you how to see what data is traveling over the network, and the different hardware to help you with networking at home or at school!

MidBit Technologies: SharkTap Gigabit Ethernet Sniffer

1. Will do 10/100/1000
2. PoE Passthrough
3. 350mA draw at 5volts (USB Powered)
4. Auto-MDIX
5. Aggregates both sides of the conversation to the receive port on the tap

-- (This DOES mean that if the total aggregate bandwidth exceeds 1Gbps, packets will drop

* Drops any packets going into the Tap port

Step 1: Get a Tapping device

1. Gig, 10/100, aggregating, tap, hub, SPAN/Mirror port
2. See episode 63 of "Know How"
3. Padre prefers the Netoptics Gig Zero Delay Tap – But that runs $700-$1000 USED!
4. A much more affordable option is the "Throwing Star LAN Tap Pro" from the HakShop - $39.99

* But my new AFFORDABLE favorite is the SharkTap

Step 2: Get a device capable of receiving the tap data stream

1. Anything with a WIRED port that is capable of receiving the full speed of your chosen tap
2. USB adapters are fine but remember that USB 2.0 devices top out at 480Mbps. If you're using a Gig tap, you'll drop traffic once the pipe is less than half full.

Step 3: Get Wireshark (www.wireshark.org)

• Mac/PC/Linux – 32/64bit – Choose the version that is right for you.

Step 4: Choose where to place your tap

1. The tap will capture the traffic going between the two devices on either side of the tap.
2. Tapping the Externals will give you ALL devices on your network.
3. Tapping the Wireless AP will give you ONLY the devices connected wirelessly
4. Tapping a specific desktop/laptop/set-top box will give you ONLY that traffic

Step 5: Capture

Step 6: Analyze
Looking for Outgoing Streams: Are you a Spambot?

1. Filter for SMTP: Look for SMTP packets when your computer is supposedly idle
2. Filter for DNS: look for sites you don't recognize.

Looking for "Top Talkers"

1. Statistics – "Conversations" – "IPv4"
2. Click "Bytes" to sort by Top Talkers

You can see the origin and destination of your traffic

Looking for Usernames/Passwords in the clear

1. In the "Filter" field, type " – "tcp contains username"

This will give you all the packets that contain the string "username" in the clear

Looking for Network Congestion

1. tcp.analysis.retransmissions

Using LEDs Padre helps Patrick create an awesome hand in a jar from Doctor Who, and learn how to make armor for Halloween or any cosplay costume!

Creating cosplay armor (foam > cardboard)

Created armor for Sabine from Star Wars Rebels

1. Get as many reference photos as you can!
2. Use large sheets of paper or posterboard to create templates (or Builder's Paper)
3. Decide what foam to use (6mm or 2mm craft foam, 1/2" or 1/4" floor mats, L-200 EVA foam)
4. Cut based on template
5. Apply heat for curves (Heat gun is best.)
6. Glue (Epoxy or Super Glue.)
7. Sanding & Bondo
8. Apply smooth coat (Modge Podge)
9. Paint (Multiple coats)
10. Wait for paint to dry! A week is best.
11. Attach Velcro (You want it removable: easier to put on, washing, packing, etc.)
12. Enjoy!
