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...
The team Digitabulum is Manuvr's flagship project. Here is out team. Ian Lindsay started the project in 2014, and is the hardware designer and low-level bit-pusher. Brent Long builds 3D augmented-reality applications. Josh Treadwell is an electronic...
Hardware:The hardware is not very complexe if you're familiar with Raspberry Pi. The screen is a recycled one from office, a standard 19" DVI. The resolution is 1280x1024. It's rotated in portrait mode.The printer is an Epson TM-T20II, connected to the...
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,...
UPDATE 02/11/2017Previously mentioned bugs pertained to lots of noise while playing video streams. This was almost completely resolved by slowing down SPI to 8Mhz and increasing frame rate to 40. Another final part may be driving 5v SPI leds with a 3.3v...
This board is part of Fyber Labs Flex Module project.Biopotential signals are low frequency small voltage output that need very clean power and low cross-talk routing.Example signal types(source): EEG:Surface 5 mV 200HzScalp 300uV 100HzEMG:On skin 10...
The delta uses KF-m 3 airfoil and it is optimized to fly slow while carrying a payload. It flights for 40 minutes with 2 2200mAh LiPo batteries. A video of the delta flying.I got a lot of help in the RCGroups forum and now I need to create a thread for...
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),...

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...
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...
Fortunately I came across this great Hackaday page by Patrick! https://hackaday.io/project/9461-lifepo4weredpi He was nice enough to answer questions and help me with my design. My previous 2 layouts were failures, shutting down after only 4A! ...
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...
