  • Collection of open-source digital design components ("IP Cores")
    LibreCores is your gateway to free and open source digital designs and other components that you can use and re-use in your digital designs. Towards this goal, LibreCores provides you a comprehensive and easy directory of digital design components ("IP Cores"),
    means to assess the quality of those components, and documentation to learn more about the use and contribution to free and open source digital designs.

  • Audio Bootloader for Attiny85 Microcontrollers
    You can simply program an Attiny85 via the audio output of a PC, Smartphone or audio-player.

    Only a low-part count circuit is needed.

    The bootloader presented here has the following features:
       low memory footprint: ~1KB
       [full Arduino IDE integration] (https://github.com/8BitMixtape/8Bit-Mixtape-NEO/wiki/3_3-IDE-integration)
       automatic Baudrate detection and callibration
       very simple circuit: two 10 k resistors and a 100 nF capacitor are needed to connect the microcontroller to the audio output of the PC or audio player
       one pin for data transmission is needed
       an optional led indicator, needs an extra pin, for the state of the boot loader
       as hex/binary to wav converter, programmed in java, is also available. It works on win and linux

  • Current differencing transconductance amplifier - Wikipedia
    Instead of
    "The CDTA is not free from parasitic input capacitances and it can operate in a wide frequency range due to current-mode operation."
    something like "the CDTA is less sensitive to  parasitic input capacitances..."
    is more appropriate.

  • Arduino HP-IB Adapter
    The Arduino HP-IB Adapter is a device that implements the HP-IB protocol in software. The device consists of an Arduino Mega board, a prototype Shield and an Ethernet Shield for connection to the LAN. It offers the means to provide support for HP-IB even when dedicated controllers such as the TMS9914A are no longer available.
