Hey Know-It-Alls...

First, this is ENTIRELY THEORETICAL. Take it as no more than drippings from a sleep-deprived brain.

That being said: If +Bryan Burnett and I were to start doing two, slightly shorter episodes of KH each week, split between DIY and Maker topics, with a single project per episode but the same basic format... would you watch?

I agree with +Ben Yanke​ - making the clips more sharable by trimming to one subject will help us recruit new know-holes ;-) I assume the most of us are fine with a 1+ hour sitting, but new viewers may need smaller bites to be persuaded ;-)

Sure it might be ghettotastic but it got the job done. Who knew amazon would ship the x5c in a phone Holder for video?

I covered my hand truck at the last placed I worked (used to drag around tools) in flame duct tape.  (also 3d printed skull hub cabs)

Hey all,

I'm wanting to be able to monitor data usage by device/IP on my home network.  Are there any free software options for this?  Thanks!

Simple monitoring.  I just want to know which device on my network is sucking the most bandwidth.  Thats it.

I am a student currently working on my BS in IT Admin management.  Summer is almost here.  For my Summer project I am building a computer lab separate from my home network so I can practice networking.  I have a tower that I will be putting Windows Server 2012 on.  I am thinking cheap laptops for clients because of space.  I can do towers with a KVM switch if necessary.  It just depends on what I find.  I am looking for do's and dont's from anyone who has done this.  I am also looking for an inexpensive managed switch that I can console into.  Any suggestions?  Thanks.  Larry

Raspberry Pi's on a network would be a very small footprint and be really cheap. And you can repurpose them for a lot of other things. Interesting idea!

So, my turn to lose a propeller in mid-air. The quad fell from about 150-200'. At least, I >think< one of the propellers unscrewed themselves.
I was hoping to have great video of the event, but it the impact apparently killed the camera, too.

I would agree with +Wayne Hobbins It is best to use cw and ccw prop nuts/studs. Even if you do use loctite. Can't be too safe.

Just finished the episode on DMX lighting. I thought is was very informative and was most excited because it in my field. If Know How does another episode on lighting here are some things you could discuss. 

1. DMX needs termination. Most likely the lights that were used in the episode were self terminating. A DMX terminator is relatively cheap http://www.amazon.com/Hosa-DMT-414-DMX512-XLR3M-Terminator/dp/B000PO1H94 or you can make one by soldering a 120 ohm resistor between pins 2 and three.  

2. If you want to control each light separately you will need to give it a different starting address or channel. When dealing with multiple lights, get a good app to help with the math. I like DMX calc by West side systems http://www.westsidesystems.com/f-pl/f-dmx/dmx.html

3. If you start to discuss lighting the people in podcasts a good discussion  would be on color temperature  and the challenges in blending lights that produce different color temperatures. 

Again Great Episode.

I was making a RPI NAS by following the tutorial here: http://www.howtogeek.com/139433/how-to-turn-a-raspberry-pi-into-a-low-power-network-storage-device/ and after following it, I still cannot write files to the Samba Share.  The error occurs that is depicted in the picture below.  I tried chmod the folder with the command "sudo chmod ug+rw /media/NAS" which should allow any user in the group "users" (The signin Username) to r/w to the directory.

Any help is greatly appreciated as I do not know what to do.

Can anyone tell me what FPV system they are using that would be decent for my new build?

I'm using the FatShark Attitude googles and I like them, but I bought them for the "Head Tracker" option.
You might watch this for some info

He mentions later in the video that he is going to do a comparison video of all the different googles.

I really dig Stego, but need to look into this a bit more.
Java/JS is just a plain scarey but needed tech.  NoScript works well at crippling your experience/ability.

I have a feeling there is a know how episode on this,may have forgotten or not seen it, but I'm interested in screen capture devices. This time for HDMI or dvi. I saw a card with two HDMI ports and from my basic,quick Google search HDMI from my video card goes into one port and a HDMI cable from the second port goes into my monitor. I'm mainly looking for a good card that I can use to record playing stream games so I can save game play or replays. Mostly for "offline" capture.I don't plan on streaming it. Any recommendations?

I've had good experiences with them for TV tuners so I'll have to look into it mor. I saw the avermedia one padre mentioned but the reviews for the pcie version aren't too pleasant. But since most were complaining about live stream I'm pretty sure I'll be fine.

Hey, so about a month ago our router finally died (it was a Linksys WRT54GS) and we now have a Linksys EA6500. It works great... in some rooms. With the old router we got decent speeds pretty much every where we needed it, but with the new one we get amazing speeds when we're about 20 ft (max) from it. Also some of our older computers randomly disconnect/won't connect at all. Moving the router to a better location isn't really an option. Any help is appreciated!

+Luke Kolarsky If that doesn't work you might try an extender. You'll loose some speed, but it'll increase the wifi distance.

So I have soldered a couple of electronics projects, and I like to challenge my soldering skills. Does anyone know of some soldering kits that are more advance/tricky to make? It does not matter if it is SMD or through hole components.

Take an old device de-solder it and solder it.  Then see if it will still work.  If not, find the bridge or cold joint.

So I have Dazzle capture card. They are ok, they are let down by the software that comes with it. The software are design only for converting RCA signal to DVD. And the quality of the video are very bad. But I tried my dazzle with VLC and the picture quality improved. I tried to save/convert option in VLC but the audio fell out of sync after 5 min. does any baddy have suggestion for a free capturing software that will work with my dazzle?  

Also if anybody is thinks of converting old family VHS tapes or another tape format…. The tapes “signal” only last for about 15 years. After that the signal is degrading.
