Hi everybody,In this post I'm gonna share with you my new application that simple embedded server to control and measure somethings over the internet.Nowadays as you know IoT is popular topic and may become more popular. Even there is a motto that "by...
As a student myself, I think some music players can be hard to afford. Especially the ones small and compact, the price is usually pretty high ---- take iPod as an example, it cost $149. Which is overpriced. This project lets you build an MP3 player/Camera...
Architecture Wikipedia article: Transport Triggered Architecture Since the CPU doesn't utilize microcode (I don't have an EPROM burner so one of the goals was to create the CPU without EPROM chips), it can do only one simple thing: move data during...
Revamping an old Parallax Boe-BotThis project is basically the refurbishing and revamping of an old Parallax Boe-Bot robot kit. This kit and robot are still made by Parallax, it comes with a basic stamp board, metal chassis, wheels, continuous servos,...
The components for this project are following:x1 NeoGeo Pocket.x1 NeoGeo Pocketx1 Raspberry Pi 3 or Rpi2 (less power consumption but less performance).x1 2.4 PiTFT from adafruitx1 Teensy 3.2.x1 blackberry trackball breakout board from SparkFun or Icstation...
Goertzel's AlgorithmThis algorithm can be used to detect a frequency from sampled data.Here is a link (http://www.mstarlabs.com/dsp/goertzel/goertzel.html).Here is the preliminary code for a spectrum analyzer:#include #include #include // Uses Daniil...
This started with my desire to modify my Kill-A-Watt meter to report power to Thingspeak. Got it mostly working, but still had some offset/inaccuracy issues due to sampling rate (and discovered it was off by a factor of 2 because the original X2 power...
A simple circuit using an Op-Amp and variable resistance. Its a simple amplifier stage.Using a simple line drawing program written in python, draw out the bones of the circuit to scale as it would appear on the circuit board and save the resulting image...
There are not enough pins on a basic Arduino to provide 2 pins each to 8 HC-SR04 units. I2C bus would be the answer, but the bus itself is not fast enough for accurate echo measurement, and the only reference to an I2C library for these in the playground...
Way back in the late 80s, I remember seeing a TV show (I think it was Amazing Stories) which featured an interesting clock. It was round, black, about the same size as a normal wall clock, and all done up in LEDs. The LEDs appeared to be what I now recognize...
What I wanted out of this supply:Be small and compactoutput adjustable to 20VUse mostly salvaged and recycled componentsdisplay the voltage and currentFine adjustment of output voltageAdjustable current limiting up to 1AMains suppliedLinear topology...
-- VGA display using a bus_master as a GPU for the HPS. Display from SDRAM. A simple GPU was written that only writes rectangles. It takes corners (x1,y1 and x2,y2) and colors from the HPS in SRAM scratchpad memory and displays them into SDRAM-buffered...
That’s right, the robot I teach you to make this time is the BB-8 in the Star Wars: The Force Awakens. Ever since the first official trailer was released in October, the adorable BB-8 in its peculiar design has attracted a large number of fans and its...
Things we are using here:-FX Micro VTX Camera Combo x2 (one for headset, one for blimp)-NexWave 5GZ video receiver for headset-Eachine VR-007 headset -Teensy Microcontroller-AXL337 accelerometer breakout board from Sparkfun
