    Bit-banging Ethernet On An ATTiny85

    hackaday.com 29 Aug '14, 2pm

    There are other reasons besides POE that you might want isolation. I have been shocked by holding the end of an Ethernet cable in one hand, and touching a grounded chassis with the other. Connecting a meter, I found the Ethernet wires capable of delivering ~90VAC while open, or ~3mA w...

    Extrinsic Motivation: Daisy Kite Airborne Wind Turbine

  • Stupid Security In A Security System

    hackaday.com 28 Aug '14, 8pm

    Ehh. It isn’t too surprising. The alarm panel itself is supposed to be protected by the tamper switch which is to alert you to somebody fiddling with the panel when the system is not armed. As noted by yaehob, if somebody can get into your building and open the panel whilst everybody ...

    Droning On: Maiden Flights

    hackaday.com 28 Aug '14, 5pm

    When we last left off, the Hackaday Drone Testbed was just a box of parts on workbench. Things have changed quite a bit since then! Let’s get straight to the build. With the arms built and the speed controls soldered up, it was simply a matter of bolting the frame itself together. The...

    800 inches per minute at 0.00025″ Resolution

    hackaday.com 28 Aug '14, 2pm

    Inches per minute and 0.00025″ confuse people here??? I don’t understand at all. Surely some people here are machinists or operate even CNC machines. I run a 5 axis HAAS mill all day. IPM, or inches per minute, is a basic measurement of material removal speed for any machinist. As is ...

  • DEFCON: Blackphone

    hackaday.com 27 Aug '14, 8pm

    I’m not refering to Silent Circle, unless they wrote the device driver layer for this phone which I highly doubt. I’m talking about Google mainly and its hardware partners. A device driver has full access to the hardware and nobody but whom has its sources (Google) can control it. Thi...

    Make Your Own UV Exposure Box For PCB Manufacture At Home

    hackaday.com 27 Aug '14, 8am

    Why a planter box? To be honest, it was simply the first opaque container [Shane] found, so he decided to base the design around it. Inside the planter box are two 15W fluorescent daytime bulbs which output a similar amount of UV to normal sunlight. A mirror is placed below them to he...

  • New Chip Alert: The ESP8266 WiFi Module (It’s $5)

    hackaday.com 26 Aug '14, 11pm

    Why is it cool? It’s a WiFi module with an SOC, making it somewhat similar to TI’s CC300 in conception (A.K.A. the thing that makes the Spark Core so appealing), in that a microcontroller on the module takes care of all the WiFi, TCP/IP stack, and the overhead found in an 802.11 netwo...

    ARM-BMW, The Open Hardware Cortex-M0 Development Board

    hackaday.com 26 Aug '14, 8pm

    I do love little boards like this, but google is right, ARM is going to be marginalized until the IO is standardized. Everyone uses different serial ports, GPIO pins, etc. for everything. Heck, ST can’t even use the same pins for USB control on their own boards, and they have control ...

    It uses two 500W 24V DC motors (MY1929Z2) on an aluminum check plate frame, with the rest of the structure made from steel plumbing and fittings. What we really like is the steering linkage; similar to a real Segway, you pull the handle in the direction you want to turn. He’s accompli...
