Edge Lit 481 Digital Voltmeter Display

at 11:36 am. Filed under Complex Hacks, Crazy Hacks

 

This Edge Lit 481 Digital Voltmeter Display totally makes me want to build a clock with this mechanism. Can you imagine talking a measurement with this meter that oscillates, it would make a ton of noise. I can see this being great help if you were siting on a stable reading and waiting for something to avalanche.

“These early NLS digital meters used a resistor dividing network and stepper relays to select the display digits. If you see one of these in operation you will hear a lot of mechanical relay noise as the range and digits are selected.”

Inside the TESLA Model S Battery

at 11:57 pm. Filed under Complex Hacks, Cool Gadgets

 

 
jehugarcia shows us what is Inside the TESLA Model S Battery. There are lots of bolts holding the battery pack together. Why are they ripping apart this huge battery? To make smaller battery packs to power other electric cars. As you can see from the video this pack is built like a tank. It is not meant to be services since it is all glued together. With a bit of elbow grease they can get into it though. Nice to see they are taking lots of precautions when working with the discrete modules since they hold a ton of energy and could cause some major destruction! This obviously wouldn’t be worth it to take a new battery apart but this one was taken from a crashed car where the battery survived.  If you want some of these modules for your project you can get them at EV West.

Gesture Controlled Lamp powered by Raspberry Pi

at 12:06 pm. Filed under Complex Hacks, Electronic Hacks

 

 

This Gesture Controlled Lamp is powered by Raspberry Pi. An infrared camera is connected to the Raspberry Pi allowing the system to monitor for wand movements since the wand has an IR LED build into it. OpenCV is used to decipher the wand movements. There are a few simple gestures that are recognized to magically control the light.

“After a recent trip to Universal’s Wizarding World of Harry Potter, my daughters and I decided to create a project that could use the interactive wands from the theme park, at home, to control our own props and gadgets. We called it Raspberry Potter because it was powered with a Raspberry Pi. We demonstrated the project last year at the Minneapolis/St. Paul Mini Maker Faire and this article — Ollivander’s Lamp — is the latest extension of that project.”

Paper Airplane Gun version 2

at 8:29 pm. Filed under Complex Hacks

 

 

We have seen Paper Airplane making systems in the past, this one is super fast. Taking a stack of paper and jamming it through a set of rollers bending and folding as it goes makes for a very fast plane machine. The use is great, stack it full of flyers and fly them at your targets. Doing this from a tall building might be lots of fun!

Cardboard Computer Build

at 10:28 pm. Filed under Complex Hacks, Computer Hacks, Cool Gadgets, What Were They Thinking

 

Mark Nesselhaus is building a computer the hard way, by using handfuls of transistors and cardboard.

 

“Attempt to build a computer using cardboard and brass paper fasteners as the base material for all of the logic circuits. Why? Well, the cardboard is free as my workplace puts it in the dumpster and I do not have the funds to buy better material. All of the electronic parts thus far were given to me by a friend who passed away and what better tribute than to build a computer. Except for the ALU all gates are either Nand or Nor using DTL. The transistors used are npn 2n2222 type or pnp 2n3906”

Raspberry Pi Zero Ambient Lighting using Hyperion

at 10:29 pm. Filed under Complex Hacks, Cool Gadgets, Electronic Hacks

 

If you want to jazz up your tv with an Ambilight system now might be the time. We have seen other systems in the past that were impressive but not as good as this system. This new system is still a bit kludgy but seems to work very well and is nice and flexible to work with most systems. The Raspberry Pi Zero running Hyperion is the heart of the system and allows for lots of customization. The basics of this system takes in your TV HDMI signal into a splitter, one feed goes directly to your TV and the other goes into the an HDMI to AV converter. This AV signal is then fed into an AV to USB converter. The converter is plugged into a USB port of the Pi. This is not an ideal chain but since HDMI is a secure transport of video data there is no simple way for the Pi to read in the HDMI data. Now that the Hyperion software running on the Pi can see the live video signal that the TV is displaying it can calculate and output the appropriate codes that are fired down the serial LED string. Using the serial LED tape allows for a very simple LED layout.

Poison Tap

at 10:18 pm. Filed under Complex Hacks, Computer Hacks, Educational

 

Samy Kamkar had built a device that is called Poison Tap. It is a Raspberry Pi Zero which plugs into the victims USB port. The device that looks like an Ethernet connection, your computer inherently trusts this connection and this is where the exploit starts.

  • emulates an Ethernet device over USB (or Thunderbolt)
  • hijacks all Internet traffic from the machine (despite being a low priority/unknown network interface)
  • siphons and stores HTTP cookies and sessions from the web browser for the Alexa top 1,000,000 websites
  • exposes the internal router to the attacker, making it accessible remotely via outbound WebSocket and DNS rebinding (thanks Matt Austin for rebinding idea!)
  • installs a persistent web-based backdoor in HTTP cache for hundreds of thousands of domains and common Javascript CDN URLs, all with access to the user’s cookies via cache poisoning
  • allows attacker to remotely force the user to make HTTP requests and proxy back responses (GET & POSTs) with the user’s cookies on any backdoored domain
  • does not require the machine to be unlocked
  • backdoors and remote access persist even after device is removed and attacker sashays away
