The MK01 features a 3D printed dovetail jointed snap together case, low res 4.3" tft composite backup monitor, 2cell 7.4 volt LiPo battery, 5 volt stepping voltage regulator from China that powers the whole thing, a random USB hub circuit removed from...
I bought myself relatively cheap ~430USD working spectrum analyzer Advantest r4131c. With first inspection everything was excellent. However after little more investigation frequency readout was inaccurate and unstable. Something wrong with PLL i thought....
Indrium (a distortion of the Sanskrit word "indriyam" which means "sense organ") is a family of long range RF devices that can help you monitor a distributed network of sensors. Indirum uses sub 1 GHz RF, and I've decided to build everything around the...
Already done: Ordered & received panels.Created an aluminium frame for mounting the panels, the power supply and the receiver card.Mounted everything onto the frame.Mounted it into the wall.installed an Intel Atom-based board running our software. TODO:...
For this year's world create day, we are putting up an exhibition and demonstration of projects and doing a workshop on hacking toys for engineering. We will be showcasing everything a budding maker needs to get started and we will be doing it in hack-a-day...
The goal is to build the following modules:3x VCO based on CEM3340 chips3x Low Pass VCF based on SSM chip1x noise generator4x VCA3x AHDSR EG with auto trig 3x LFOA few mixers and arbitrary voltage generatorsMIDI-CV interface with multichannel arpeggiator/sequencerEverything...
Maintaining Windows and a closed source app on an obsolete computer was a non-starter for me. I loaded LinuxCNC on a Core 2 Quad box, and was able to verify that everything worked. I wanted to be able to control the system from a laptop USB port. I chose...
footage of the robot walking with an evolved gait can be seen in the below video:edphysics.co.uk/robot.mp4Note: I made this robot for school, as part of my Extended Project Qualification (started age 17). I do not get the grade till mid august so may...
Instead of re-inventing the wheel, I had a look online and the schematics for DIY ST-Link boards were readily available, I have linked the two websites I referred to when designing this project. All that remained was to design in the isololation, and...
This project is more of an analysis of work done to use an 8-bit PIC micro-controller as a synchronous buck controller. While implemented using a PIC, other controllers could be used. The PDF in the files section contains the analysis.The...
I had a need to be able to send messages to an RGB LED panel quickly and easily. I used MQTT as all my other MQTT clients and servers would be able to send messages directly to the panel.All the code, libraries, images and everything else is run from...
The idea is to project an informative following image or a small animation at the foot of passersby. - for tracking walking people I'm using a LIDAR (scanse sweep) with a blob's centroids detection script based on the Sklearn Library - for moving...
The main goals of this project are:keep the plant aliveuse as little power as possiblenotify me via internet if power/water runs lowlog temp, humidity, soil resistenceone charge should last atleast 28 daysCurrently I use an ESP8266 and programm it with...
Main goals for this terrarium:- everything must be easily replaceable or upgradeable- save energy and use grow lights only during the cloudy days- maintain optimal temperature and humidity for plants- must look more or less nice in my living room (hide...
Compared to the original #192:LED design. Nearly everything did changesmaller: 15.8mm x 14.6mmNo complicated Multiplexing anymore! LEDs are WS2812 style ones in a metric 1515 packagesmarter: MCU is a SAMD21USB: quite more convienat and easier to...
