Mini H Quads. DC-Sparky-FC - Dragon Circuits Sparky Flight Controller Auto-Pilot New!
Dragon Circuits Sparky Flight Controller Auto-Pilot Dragon Circuits would like to introduce the highly anticipated Sparky flight controller. We have taken this amazing flight controller designed by Peabody124 for Tau Labs and built it here in the USA using the same stringent inspection and manufacturing methods used for our aerospace and military customers. All the sensors in Sparky are genuine, no cloned sensors here. Specs: Vehicle compatibility options include: - Multirotor – Quad X, Quad +, Hex, Hex x, Hex Y6, Octo, Octo V, Octo Coax X, Octo Coax + Ground- Car/Truck, Motorcycle, Tank Helicopter.- CCPM, FP Fixed Wing.- Standard (elevator, aileron, rudder), Elevon and VTail mixing Custom – mix your own settings for almost any vehicle.

[More information] (11 Oct 2014) Logisim is an educational tool for designing and simulating digital logic circuits. With its simple toolbar interface and simulation of circuits as you build them, it is simple enough to facilitate learning the most basic concepts related to logic circuits. With the capacity to build larger circuits from smaller subcircuits, and to draw bundles of wires with a single mouse drag, Logisim can be used (and is used) to design and simulate entire CPUs for educational purposes. Logisim is used by students at colleges and universities around the world in many types of classes, ranging from a brief unit on logic in general-education computer science surveys, to computer organization courses, to full-semester courses on computer architecture.

Although admitably not the best quality, I decided to use these particular jacks sockets from an old sound blaster live sound card, due to the fact I could seal them properly to stop an ingress of resin. (The below picture has been Mirrored) Pre Casting tests....... Both of the audio Jack Socket sides were removed during the sealing process, the sides were then replaced after applying resin around all the edges Resin was also dripped around all the connections pins around the bottom, to ensure an airtight seal. End mills - ShapeOko. Good info about end mills on BuildYourCNC (Following information is from the enco website) End Mill Selection Summary Select the shortest possible end mill for the greatest rigidity Select two or three flutes for slotting or heavy stock removal Select multiple flutes for finishing and greater rigidity Use the largest diameter possible for added strength and rigidity Use cobalt, PM/Plus, and carbide for tougher and harder materials, and for high production applications Apply coatings for higher feeds, speeds, and tool life.

Freed from the constraints of mass production, we plan to explore diverse materials, shapes, and functions. Biquad Antenna Construction. Biquad Antenna Construction (first published September 2002) This page details the construction of a biquad antenna. The biquad antenna is easy to build, and provides a reliable 11dBi gain, with a fairly wide beamwidth. Background completed biquad antenna I've done quite a bit of experimentation and testing with various home made dipoles for 24dBi Conifer dishes, and have managed to increase the performance of the dish. Amigojapan.github.com/Arduino-Retro-Computer-TV/ Arduino Retro Computer with oard and SD card and BASIC interpreter for TV Copyright 2012 Usmar A Padow usmpadow@gmail.com (also known as amigojapan on freenode IRC and on youtube) This is a stand-alone computer that you can build easily May 13 2012: Finally released the TV version of the computer!
May 7 2012: Added a BASIC preprocessor made in python that allows you to write code withought line numbers and to use labels. the preprocessor adds the lines and changes the labels to line numbers. Also made an AmericanFootball BASIC game, as an example of how to use the preprocessor. Also made some small changes to the firmware, so make sure to update that too. May 10 2012: Fixed a bug that allowed only 127 lines of BASIC in one program, now allows 255 lines, I will increase this number when I get a chance.

Best of all - he published his schematics, documented the inner workings well, and even published the firmware for anyone to build. Right now, you can purchase the PCB's for the kit. He is contemplating offering a kit version of the clock. Visit his site and follow the instructions if you're interested in a future kit version. Clock Options.
