Setting up my Wyze v2 Camera

So… I made a trip to Microcenter.  Fully intending to get in and out with just a couple spools of filament since I seemed to be running out of the material I was using for the light staves (Inland’s 1.75mm Silver PLA filament, #notsponsoredbutIusealotofit).

Yeah, that didn’t work out as planned.  I never walk out of Microcenter with just what I intended to buy.  I ended up getting a Wyze v2 camera.  And some purge filament.  And a new shirt…

Just following the first rule of engineering.

I’ve been considering getting a wifi camera to watch my 3D printer from another room and potentially monitor while out and about.  So I got the Wyze v2, as it was cheap and available.  My only gripe was that it had a built-in microphone that is electronically controlled, and I’ve seen reviews of previous versions of Wyze cameras that spoke of security issues with data leaking and/or being routed suspiciously.  Supposedly this has been fixed somewhat recently.

Video footage I was okay with, because by placing the camera carefully (and putting it on the same light switch controlled circuit that I use to run the printer) I can make sure that the camera only sees what I want it to see.  Most of the time I won’t care if people are watching my 3D printer run.

However, sound isn’t so simple a matter.  Sound bounces around, and I don’t want any private conversations accidentally (???) being streamed. But, I figured, what the heck, it’s a $25 camera, I’ll open it up and cut the microphone out if I have to!  If I mess it up, it’s not like I’ve broken a super expensive camera in the process.

When I got home I found out that other people have the same concerns, and this guy in particular had my back with his instructional video:

Hardware disabling the mic on WyzeCam v2

Turns out all you have to do is disassemble the thing, take a pair of pliers, and pull the microphone off the circuit board.  No cutting or de-soldering required!  I do highly recommend viewing his blog and watching the video, there were a couple tricks I didn’t realize at first.  Wasn’t too hard, but this other video shows the trick to getting the bottom off easier than the other guy’s.

So far so good, the camera now streams video but not sound.  But it only goes to the phone apps.  Dammit.I did a bit of searching around, and found this guide made by a channel called Gross Technology.  It explains exactly how to set it up for streaming to your PC on the same network.  Apparently it’s a new feature for these cameras.

Now I can get it to stream to VLC.Demo of printer monitoring2.pngOne step closer to my goal!  I eventually want to set up a control page where this video feed is streamed so I can view it remotely, whether on my phone or PC, ideally with a connection to the wifi printer controls so I can kill a failing print.  Needs a big red button on it.  That’s going to take a bit more than I plan to work on at the moment.  I just couldn’t resist though, and so far it’s kinda been a one evening fun learning project.

I did take enough time to start setting up the printer’s wifi controls, but that’s probably gonna require a firmware update to get working properly.  And those come with big warnings of DO NOT DO THIS IF YOU CAN’T BE WITHOUT YOUR PRINTER FOR A FEW DAYS.  Given that I’m in the middle of a couple of time sensitive projects with it, I think I’ll wait till they are done.  Maybe make a day of it along with the other maintenance items that need to be done.

In the meantime, I can check on my prints from within VR using Oculus’s desktop viewer without having to pause and duck out of VR.  Eventually I’ll be able to check whether my printer has something on it and send files to it over the wifi.  I hope to streamline the printing and monitoring process as I go along.  

Addendum: I use VLC to watch the video stream for now. Turned out I had been using the Windows store version, which is stripped down and I also couldn’t figure out where it was located. That was only an issue because I was trying to make a direct shortcut to the stream on my desktop. Anyway, I’ve installed the full version of VLC, and now have a shortcut that goes directly to the camera feed, so I don’t have to go through additional steps anymore. Doubleclick to watch the printer. Done.

 

New Logo/Maker Coin

So, if anyone’s been paying attention, I’ve created a new logo for this site, based on a new maker coin that I designed.

For a brief explanation/history of these, here’s the guy who came up with them.

Video made by Maker’s Muse, please support his videos

It’s an object you can use as the equivalent of a filament swatch and to show people what 3D printing can make.  It’s helpful as a “1 standard print” for testing filaments, printer calibration, and slicer settings.

I thought it was about time that I made one of my own.  Then, through some manipulation in a couple programs, I converted it into a logo.  I think the symbolism is kinda obvious.  Technology + magic + a medieval wooden door = Technomancer’s Sanctum.

If you want to print one of your own, you can find it on Thingiverse here:

Technomancer’s Sanctum Maker Coin

This one I printed (in two pieces) on my replacement 3D printer, which finally arrived today!  Seems to work pretty well.  The parts printed fine on the first attempt, and the center door pressfit solidly into the coin!

 

In other news:

Borderlands 3 came out last week, so I’ve been playing that over the weekend, and having a blast.  I’m playing as Moze, so when the fecal matter hits the cooling unit I can jump into my mech and lay waste to my foes!  Still… in the words of the greenskins… NEED MOAR DAKKA!  I’m gonna have to see if I can fire more bullets per second.  I’m playing a gunner, after all.

I have business cards now!  I got tired of trying to find a scrap of paper to write down the web address for my blog when I get questions about my hobbies, so I’m now carrying some business cards wherever I go.  It should make it much easier to get the word out.

Project Update 08/07/19: Final Prototyping Stages

I think I’m about to the wrapping up point for the brackets on this thing.  As mentioned in a previous post, I’ve been working through a bunch of prototype parts, and enjoying learning more about Fusion360 in the meantime.  I haven’t figure out how to get a recording of it saved yet, but it has a feature where it can play through every change you’ve made to the model file from beginning to end.  Kinda cool to watch.  I’ll try to remember to post a video if I can figure out how to record and edit it.

Anyway, here’s where I’ve gotten to with some parts for test fitting:

In the top left I wanted some sort of knob for grabbing the tray easier, so I mixed in the handle for one of the keys from Ready Player One.  Sadly, it feels too flimsy, so I’m not including it in the final model, and I think I can get enough grip on it without an actual knob.

From this angle you can see the retaining nuts that hold the screws for the latch.

Here are the mounting holes for the bottom side.

The parts on the left side of the keyboard are a slightly later generation of model than the ones on the right.  The left side ones are snap fit, whereas the ones on the right are loose.  I’m still figuring out tolerances with my printer.

I’m on what should be the last iteration of the parts, with some of the parts on the printer right now.  It’s gonna take a few nights of overnight printing to finish, but hopefully these will be the last ones, short of possibly a template for drilling the holes.

Hopefully I’ll get to the point of drilling holes, epoxying parts, and priming the whole rig soon.  This thing is coming together!

 

Assorted Updates:

A lot of stickers came in for me to put on the case.  Apparently there are pre-mixed sets of stickers for stuff like Ready Player One, so I may be making a whole collage of the back, just making sure to make the ones I specifically want show up on top.

I added a dimmable Ikea lamp to my workbench for a bit more light.  It can be hard to look at, so at the moment I’ve got some foil on there as a reflector and shade.

I found some lettered sticky tabs, so I’ve started putting yet more tabs in my rulebooks so I can find things in the long lists in the rulebooks.  Now I should be able to look up monsters, spells, and magic items even more quickly.

Tabs, for when you haven’t got time for a research montage mid-session.

Snapmaker 2.0 Kickstarter Kickoff

The Snapmaker 2 Kickstarter started this morning… and all the early bird specials sold out within minutes.  The whole thing was fully funded 10 times over in 10 minutes!

You can find it here:

Snapmaker 2.0 Kickstarter

Now we finally know the full specs, and pricing.  They are priced (with discounts) about where I expected them to be.

Sadly, I’ve been looking at my finances and to be a “responsible adult” I should probably wait until I know what a few upcoming expenses are going to be before I go spending that kind of money,  Especially since I missed the best specials.

Hopefully I’ll still be able to get this printer, as long as I’ve waited for it already.

Maker Workbench Inspiration

I think I’m going to find or make some signs with some of these quotes to put up around my workbench.  Here are some of the ones I’d most like to have:

“Sucking at something is the first step to being sorta good at something.”  ~Jake the Dog, Adventure Time

“Take chances, make mistakes, get messy!” ~Miss Frizzle, The Magic School Bus

“A journey of a thousand miles begins with a single step” ~Laozi, Chinese philosopher

“What’s the point of being grown up if you can’t be childish sometimes?” ~The Doctor, Doctor Who

“Any problem can be solved with a little ingenuity.”  ~Angus MacGyver, MacGyver

 

Technomancer’s New Worktable: Mk II

I quickly tired of the clutter, and I’ve always liked toolboxes.  I found this one at harbor freight:

tool chest

Eight Drawer Wood Tool Chest

I’ve seen it before, and the wooden toolbox had always reminded me of the custom toolboxes by dad made for his tools years ago.  I like the echo in style.

It’s felt lined, and I’ve tried to arrange the drawers and their contents similarly to how I had them laid out on the table.  The most commonly used tools are closest to the work area.  Tool trays I’m likely to use around the same time are next to each other instead of stacked, so they don’t obscure each other when open.  I’ll probably be rearranging for a bit as I get used to working with it.

Despite it’s size, it’s definitely freed up work space, and I like that it’s neat and organized.  If any family visits, most of the sharp objects that could be dangerous to kids are in one spot to be locked away from curious fingers.

Also, by collecting most of my tools into one toolbox I’ve made it that much easier for me to do demos for local groups or set up a table at a maker fair.  I’ll just have to throw the rest in there, then put the the toolbox and the 3D printer on a cart and roll it in, instead of making a bunch of trips for things.  If I need to bring my table, I can do that too, since it is portable.

I think this work area is really shaping up nicely.  Now I just need to get a steady build queue going and make the most of it!
