ParallelProgrammer. Instructions for building a parallel port programmer for the Arduino board (or any other Atmega8 chip).
Allows you to program the board on Windows without any additional equipment. Cheap and fun. (Please note, however, that this doesn't allow for communication between the computer and programs running on the board. You'll need a serial cable for that.) Rear view of connector. Equipment Tools: Soldering iron Hot glue gun (optional) You'll need (parts): (2x) 470 ohm resistor (yellow-purple-brown) (1x) 220 ohm resistor (red-red-brown) (1x) parallel port cable or parallel-to-serial adapter (2x) three wire cables with female connectors on one end, unattached wires on the other Instructions Remove any existing wires from the parallel connector. Solder 470 ohm resistors to pins 1 and 2 of the parallel connector. Parallel connector with a 470 ohm resistor soldered to pin 1. Solder a 220 ohm resistor to pin 11 of the connector. ArduinoISP. Learning Examples | Foundations | Hacking | Links This tutorial explains how to use an Arduino board as an AVR ISP (in-system programmer).
This allows you to use the board to burn the bootloader onto an AVR (e.g. the ATmega168 or ATmega328 used in Arduino). The code in this example is based on the mega-isp firmware by Randall Bohn. CircuitLab - online schematic editor & circuit simulator. Rtl-sdr – OsmoSDR. DVB-T dongles based on the Realtek RTL2832U can be used as a cheap SDR, since the chip allows transferring the raw I/Q samples to the host, which is officially used for DAB/DAB+/FM demodulation. The possibility of this has been discovered by Eric Fry (History and Discovery of RTLSDR). Antti Palosaari has not been involved in development of rtl-sdr. Specifications¶ The RTL2832U outputs 8-bit I/Q-samples, and the highest theoretically possible sample-rate is 3.2 MS/s, however, the highest sample-rate without lost samples that has been tested wit regular USB controllers so far is 2.4 MS/s. A stable sample-rate of 3.2 MS/s without lost samples is only possible with the Etron EJ168/EJ188/EJ198 series of host controllers due to their specific maximum latency.
Supported Hardware¶ People over at reddit are collecting a list of other devices that are compatible. This is the PCB of the ezcap-stick: More pictures can be found here. Software¶ RTL SDR. GNU Radio - WikiStart - gnuradio.org. Introduction¶ GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios.
It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic and commercial environments to support both wireless communications research and real-world radio systems. GNU Radio is licensed under the GNU General Public License (GPL) version 3 or later. All of the code is copyright of the Free Software Foundation. Content¶ 0. Registration for GRCon16 is now open! I. If you've never touched GNU Radio before, these pages will get you started with a running installation of GNU Radio and will show you how to take your first steps with this software radio tool. II. GNU Radio has two manuals: one for the C++ API and another for the Python API. Documentation on this wiki: New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices.
