For this project I'm using the nodeMCU development kit (NodeMCU devKit Github) to develope my code. The development kit contains a ESP8266 WiFi module, and I'm using this to wirelessly send data to the plotly streaming server. Plotly is a online browser...
I have found the SmartResponse-XE an interesting "Arduino-compatible" device. With BASIC installed and the added "Q" token (alias for PRINT) to allow realtime evaluation of simple math. However, the math functions of "+", "-", "/", "*" all...
The effect circuit works this way: A high input impedance buffer amp (T1, T2) receives the signal, which is then split in two ways: it is fed directly to one of the inputs of the mixer amp (IC1-A), and is fed into a high-pass Sallen-Key filter (T3),...
From Wikipedia, the free encyclopedia: A medical tricorder is a handheld portable scanning device to be used by consumers to self-diagnose medical conditions within seconds and take basic vital measurements. The word "tricorder" is an abbreviation of...
Emillotron - part 1 The title is a mix (a crasis) between Emilio (my name) and Mellotron. The Mellotron was used in the 1960s, in the time of the Beatles. In those years, long before “digital music”, someone invented a mechanical system...

UPDATE 01/12/2018 6:31:PMTactical flashlight scan @ 2ms CCD 8-Bit (TCD1304DG) detector circuit test: A better 1st mirror alignment and a 2nd 150mW laser line test: The plot above has a FWHM value of 1.005nm resolution. Fixed the 1st mirror position,...
As low-cost desktop 3D printing is now dominated by free and open source self-replicating rapid prototype (RepRap) derivatives, there is an intense interest in extending the scope of potential applications to manufacturing. This study describes a manufacturing...
Note: This project assumes you have Arduino IDE setup and know how to connect and write to an Arduino Uno board. Hook Up Your Servos The first step is to hook up your servos to your UNO. If you purchased the same servos I used from Amazon the wires...
Programmer Design OptionsStrip-board works well (I use A$8 41 x 144 board), but I did look at using a mini-Mega2560: I used an on-board Arduino Nano as they are cheap (and I have a couple of them lying around) and they provide serial and power.But...
Video showing the bat sonar in actionThis video shows the sensor in action. The left graph shows the identified targets. The size of the circles indicates the strength, and the location on the graph is their measured location. The graph...
current follower count,current account name and ID,three preceding follower counts. First of all, to manage to glean information from Twitter by avoiding any authentification process pertaining to the Twitter API, I chose to use a content delivery network...
The project's drive is to empower people by allowing them to have access to energy through a community driven project and a low-cost design.To this aim, this project's will explore the potential of building a low-cost alternator out of industrial plastic....
This board is part of Fyber Labs Flex Module project.Flex sensor input to ADC will be essentially DC voltage so filtering isn't critical. The buffer provides uniform impedance and somewhat linear use of the 0-3.3V ADC input for the resistance range of...
Hey guys, in this video, we will be making a compact circuit that can be fitted in a glove to control Robots using Gesture commands. It’s really cool to control a pick and place robot completely using hand gestures right? I have been making gesture...
