Supernatural Thermal Scanner Prop (Laser EMF Reader)

Supernatural Laser EMF

This is my Laser EMF reader, aka Thermal Scanner prop. The Lasers, LCD, and Camera are all functional. In addition, I added gearing to the back so the Lasers could perform a synchronized linear scan.

From the supernatural TV show, there are a variety of EMF Readers used. Especially early on. This paper outlines many of the different variations.

The handheld device seen in episode S01E14 is not an EMF Reader, it is a Thermal Scanner.  I have made a few of these now and have enough pictures to make this write up.

Part List:

 

3D Printing:
The 3D printed parts are optional. I designed them to both hold the lasers and allow them to move in sync. If you opt not to use the 3D printed parts, you can substitute christmas light holders instead.

Painting:
Some of the terminal blocks are blue and need to be painted silver. Poke the terminals into some cardboard to hold upright. Spray paint before soldering into the circuit board.

Trimming:
With the Screw Terminals installed, you have a sense of how the board is laid out. You can see that the breadboard is too long. Use a saw or dremel to trim the board shorter. If the edge is jagged, cover with electrical tape.

Wiring:
This is mostly a wiring project. Most of the wires you see running around the prop are real. There are two voltages on the board, 9V and 3V. Both run to the Slide Switch, which is DPDT with two isolated switching paths.

Wiring 9V Path: The 9V comes from a pair of 9V batteries wired in parallel to increase run time of the LCD. After the Slide Switch, the 9V is wired to power the LCD, Camera, and LEDs.

Wiring 3V Path: The 3V comes from the 2xAA and powers the lasers. After the Slide Switch, the 3V is wired to a momentary button, and finally the lasers. Polarity is not marked on the lasers, so be careful when soldering on some power wires. After powering on for the first time, the lasers need to be tuned. Take a screwdriver and spin the potentiometer on the lasers. 5 turns counter-clockwise to reset, then slowly bring the laser back on. The green lasers I linked are only 10mW, but they sell more powerful laser diodes that can be dangerous. Be careful when working with the lasers. You want them set to the lowest brightness that they can be seen across a room.

Camera Wiring: Before doing anything, test the LCD and Camera by using the cables supplied in the combo kit. Power up with a 9V battery. After confirming you did not receive a DOA device, you can proceed with cutting the cables.

The cables that come with the LCD and Camera are meant for automotive installs. I cut these wires much shorter and splice back together. Do note that the camera likely has a black lump on the cable. This blob likely contains a 12V -> 5V converter. When splicing the cables shorter, keep this block intact and splice around, do not remove.

Issues:
– Backup car lines on LCD are caused by the camera drawing them. Using a non-backup camera should fix.
– Lasers are difficult to tune so they are the same brightness.

 

Comparison of the Fire TV Stick 4K

A new firetv stick was announced today. The Fire TV Stick 4K.
https://amzn.to/2IBwuwD

Not to be confused with the more expensive FireTV, the FireTV Stick has been great as a low cost way to access streaming services. The FireTV Stick never before offered 4K. I always recommend 4K models of streaming devices. Even if you do not own a 4K TV, you will still benefit from the faster hardware when navigating the menus and get faster load times.

Prior to now, the fastest FireTV available was the FireTV 2 from 2015. The FireTV 3 pendent was marketed as 4K but was actually slower than the FireTV 2 in side by side comparisons. The $70 FireTV 3 was smaller and cheaper than the $100 FireTV 2.

This new Fire TV Stick 4K undercuts the current cheapest 4K champ from Roku. The Roku Streaming Stick+ sells for $70. The Fire TV Stick 4K is on preorder for $50, with an arrival date of October 31, 2018.

FireTV specs and prices (older models not available)

  • 2018 Fire TV Stick 4K – Quad-core 1.7 GHz – $50
  • 2016 Fire TV Stick (2) – Quad-core 1.3 GHz
  • 2014 Fire TV Stick (1) – Dual-core 1 GHz
  • 2017 Fire TV 4K – Quad-core 1.5 GHz – $70
  • 2015 Fire TV (2) – Quad-core 2.0/1.5 GHz
  • 2014 Fire TV (1) – Quad-core 1.7 GHz
  • 2018 FireTV Cube 4K – Quad-core 1.5 GHz – $120

Wyze Camera – Mini Butterbot – Rick & Morty

New baby at home so I am getting some use out of an old IP camera I placed in the nursery. My wife and I enjoyed it so much, I looked into adding a second. What I found was so cute, I 3D printed some arms and gave some wire touches.

The IP camera I was using was a Foscam FI8910W with a resolution of 640*480px, full pan/tilt, and 3rd party app compatibility. Old enough that it has no cloud features and if you want to access remotly, you better know how to add exceptions to your firewall.

Simply typing ip camera into amazon, the first non-sponsored result turned out to be a $25 marvel. The Wyze Cam. Full 1080HD, offline recording, Alexa. Perfect. Testing it out, the quality was fantastic. Remote access needed zero setup. Alexa setup just needed some basic steps to add the skill and link my account.

The base is magnetic with a pop out stand. Even though I recently watched Wall-E, instead this cube shape camera reminded me of the Butter Bot from Rick and Morty.

I made a trip to thingiverse to 3D print the appropriate arms. I drilled holes in the sides of the camera to attached the arms with a machine screw and washers. Thus, making the arms posable!

Project time: 15 minutes.

Ready Player One and TrackMania

I still call BS on Ready Player One movie adaptation. Spoilers, duh. A crazy unwinable race is taking place but you can win, if you go backwards from the starting line. Nobody discovered the secret for years! Bullsh**

Let me tell you a story about a game called TrackMania. It is a stunt based racing game. Community support has given TrackMania nearly unlimited custom tracks to play. When played at a LAN party, you can have a over 200 players on a server. All playing the same track. This is possible because each player is racing alone for the best lap time. You can see other players, but they are ghost cars that you can clip through. The match continues for a preset time, during which you can make as many attempts as you want at having the best lap time.

Because of the nature of user made tracks. Things get crazy really fast. Having the best lap time isn’t always about maintaining control of your car, making a perfect turn, or accelerating to “just” the right speed to jump from one halfpipe to the next.

So let me set this up for you. I drove 5+ hours to attend a LAN party in Menominee. It was setup in the college’s auditorium and was run like a big convention. Even inviting speakers and hosting workshops. Most folks were there for the various tournaments. The LAN party went on for THREE days. Guests were invited to stay the duration, but not necessarily play for 72 hours straight. Only weirdos best players like me stayed up all night. In the wee hours of the night, between the tournaments I signed up for, there were hours of downtime to fill. You could take a break, or join any one of the spontaneous LAN matches. TrackMania became very popular because of the number of players it supported and how crazy fun it can be.

Most tracks are a grind of memorization. Within the time limit, you can reset your car back to the start line and try again as many times as you want. Fall off the track and plummet to the ground? Reset. Flip upside down because you didn’t hit the loop de loop just right? Reset. As long as you have the lowest lap time by the end you can still win. However, the craziest tracks are so hard you can’t actually make it to the finish line more than once. The track is so crazy, with so many stunts and pitfalls, just surviving to the finish line gets you on the leaderboard.

One track in particular stands out in my memory. The time limit was set for 30 minutes. From the start line, you can see most of the track laid out before you. Dozens of half pipes and loops, jet propulsion lanes, all floating hundreds of feet in the air. My first attempt resulted in me plummeting to my demise within the first 10 seconds. With the advantage that I could see where other drivers were taking the jumps, little by little I would survive longer and longer down the track. After just 5 mins of game time, I noticed names appearing on the leaderboard. People were reaching the finish line. This was typical for our group of players. What wasn’t typical was the lap times. 5.6 seconds, 4.1 seconds, 3.5 seconds! I reset and stayed at the start line to watch them. They were driving backwards! The finish line was literally behind the starting line. You couldn’t see it at all from your perspective in the car, but if you blindly drove backwards sure enough. 3 second lap time.

My point is. This is the exact plot of the movie Ready Player One. Only in the movie, the entire overpopulated world played the race over and over. Failing for years to find the secret. Seriously? It took my group of maybe 50 people less than 10 minutes.

The plot from the book was so much better. The main character was a student with no money. The only reason he even owned a VR rig was a grant from a charity so he could attend high school safely. In VR his friends all had enough credits to go off world on the weekends. Leaving him alone on high school world. This is how he discovered and beat the first challenge. The creator wanted a student to win. That’s why the first key was placed on a school planet.

Sigh. Long story short. Go read the book. Play TrackMania.

How to Find $0.99 Digital Movies

When streaming, free with subscription is fine, free to own is better. Second best is $0.99 to buy a digital copy.

I used to have a deal alert saved on slickdeals for “free google play”. It worked for a while, each week I would receive an email listing all the free movies and songs that were currently for sale on google play. Eventually, I had to kill the deal alert when the notifications were taken over with device offers and free shipping.

I have found a replacement with JustWatch.com and their search filters. The following link searches Amazon Video for anything under $1, then sorts it by items that recently received a price drop.
https://www.justwatch.com/us/provider/amazon-video/new?content_type=movie&monetization_types=buy&max_price=1&timeline_type=pricedrops

The search results are very much “bargain bin” worthy, but there are some real gems in there if you like wacky B movies. I do!

PS Vita and Steam Remote Play with Moonlight

Back in April 2018. Shortly after Sony’s announcement that they were abandoning the PS Vita handheld. I paid $80 for my used psvita. Brand new sells for $250-300, but used models with low enough firmware for modding were being sold for $350 or more !! The psvita that I purchased was cheaper because it had the latest firmware installed and was incompatible with the current exploits for modding. Ignoring that for now, my psvita handheld turned out to be an amazing portable. Allowing me to remote play my ps4 from anywhere, lag free.  WOW!

Antenna TV Research 2018

I created the Platteville HDTV Antenna and Streaming page to be dedicated to both streaming tv and local antenna tv solutions. For Platteville WI area residents, you can replace costly CenturyLink/DirectTV/Dish with a lighter package of live streaming cable channels and Madison broadcast channels.

CenturyLink no longer allows Platteville residents to sign up for PrismTV. Pushing new customers to DirectTV. CenturyLink will sell DirectTV to you as a “bundle discount”, but it is actually the same price as unbundled if you were to purchase seperate. The cheapest plan from DirectTV costs $70, on top of what you already pay to CenturyLink for internet. New subscribers to DirectTV are signed up at a 50% discount for the first 12 months, afterwhich your bills double and they equipment rental fee you to death. When I cancelled DirectTV after the third year, my bill was around $160 per month. That is a LOT to pay for local TV channels and a few dozen cable channels!!

What is the better way?

Ammo Counter Mk3 – Collaboration with AmmoCounter.com

I have partnered with Nathaniel of AmmoCounter.com to develop the ultimate ammo counter solution.  The circuit is a derivative of my MK3 design.  I am calling it MK3 SMD.  The new circuit is exactly as tiny as my MK3, but has modifications to allow the outsourcing of manufacturing.    In addition, with Nathan’s feedback I was able to put the finishing touches on some never before seen software features.  This is so awesome!

Here is an official announcement from AmmoCounter.com  Nathan will be selling the MK3 SMD with my firmware, along with some fantastic accessories this year.  Check it out ~!

Network Connections in Windows 10

Windows 10 can be great, but a lot of things have been dumb since Windows 8. Like how they hide access to Network Connections. The window that on WinXP and Win7, was used for all things network related. All it’s functionality is still there, you just have to find it.

There are several ways to get to the now buried window, but with this method you can reach in two clicks.

  1. Right click the Start Menu and select Network Connections. Done? Ha, no. Welcome to the Network Status setting window. Hardly.
  2. Now click “Change adapter options”.  You made it~! This is the “real” Network Connections window.

For the uninitiated, this window shows the network status better than the previous Win10 Network Status window. Right click your adapter and select status to gander at all the info.
