Pizza Box Robot That Shines a Laser in Your Eye

at 10:48 pm. Filed under Computer Hacks, DIY Hacks, Electronic Hacks

 
 

Michael Reeves is a software developer at Infibit that has made a face tracking robot that is housed in a pizza box, it tries its best to find your eyes and shine a laser in them. The software that runs on a PC was written in C# and uses Emgu CV which is the .NET version of Open CV for the facial recognition portion. A web cam is connected to the computer scans for a face to attack, when detected the coordinates are sent over a serial cable to a microcontroller.  The ATmega 328 microcontroller has a few servo motors connected to laser pointer. Since the servo motors can move the laser pointer in XY positions the coordinates are used to point where it needs to. The result will annoy you and your guests. I think this would be useful at popular store displays when you need people to move along after having a quick glance. If you are looking to build your own version you can find the code here.

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”

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

Commodore SX-64 Repair

at 10:05 pm. Filed under Computer Hacks

 

Techmoan got his hands on a few SX-64 Computers. This is the portable version of the C-64 that everyone loves. He needed to do a bit of repair but in the end he got 2 working machines. They are still going for a good price since these units are still rare compared to the regular C-64 but you can find them for sale if you look hard enough. Teamed up with a C128 VIC disk drive emulator he now has access to the entire catalog of games on a simple to use device. I still remember the day when I had boxes of disks for the C-64 and being able to fit a few games on a single disk felt like such a win.

Tiny C64 Hardware Emulator

at 10:00 pm. Filed under Computer Hacks

tiny-c64-hardware-emulator

For everyone that has a fond memory of the C64 this tiny emulator might be of interest. The kickstarter failed but everything is listed so you can make your own.
Via: Make

“Hardware components

MCU: STM32F756IGK6 (ARM Cortex-M7, 216Mhz, UFBGA176)
HDMI transmitter: ADV7511W (165Mhz, LQFP-64)
SDRAM: IS42S16400J-5BL (200Mhz, 64 Mbit, FBGA)

 

Mathias created the MEMWA2 using a custom-designed 6-layer PCB just big enough (65 X 45 X 20mm) to fit the electronics, which include a STMicroelectronics MCU (Arm Cortex-M7 running @ 216MHz), 256Mb of Alliance Memory DRAM (200Mhz, 64 Mbit, FBGA) and an Analog Devices HDMI transmitter for wirelessly outputting audio and video to any display.”

HP Scanjet 4C Keytar

at 5:50 pm. Filed under Computer Hacks, Electronic Hacks

 

Using some Arduinos and a few other electronic bits this HP Scanjet 4C is made into a musical device by “playing” the stepper motor. The result is one of the best stepper motor musical items I have seen.

“You may of heard of a popular flat bed scanner named the HP Scanjet. This scanner had a hidden command set within the Scanner Control Language which allows you to send musical notes directly to the stepper motor. This is a tedious method where you have to enter the notes and durations manually into a text file (similar to G-Code on a CNC Machine). I have always used and will always use this method for my Old School music videos however I wanted to try and build a MIDI controlled stepper motor.”
