ESP8266 NodeMCU Host Experiment

ESP8266 NodeMCU Host Experiment

While experimenting with an ESP8266 module, I constructed a project with a photocell sensor that fed illumination data (resistance changes) over WIFI to a PC laptop browser. To accomplish this, ... Read More
Project March

Project March

The micro-fan project is done. The march to another one continues. Once templates are set among various project elements such as BOMs, CAD files, libraries, account settings, etc., the rest ... Read More
Stackable Modularity & Support of SBC Functions

Stackable Modularity & Support of SBC Functions

This is the thermal management module stacked upon other free-standing modules. Each module that operates on its own, or together in an integrated fashion. With a small SBC based micro ... Read More
Harmonic Difficulties With High-Speed Clock

Harmonic Difficulties With High-Speed Clock

Here I am chasing harmonics to drain them to ground. Literally. This is what I spent time doing today. Set up a draft schematic by happenstance with a strong drink, ... Read More
Voltage Controlled Oscillator Correction & Substitution

Voltage Controlled Oscillator Correction & Substitution

Well. It turns out that I ordered an XO crystal and not a VCXO crystal to build the design and prototype of the timing module. So retreated and went for ... Read More
RPi and TFT Touchscreen Set Up, Programming & Calibration

RPi and TFT Touchscreen Set Up, Programming & Calibration

Today I finished the Linux upgrades, updates, and corresponding TFT calibration. Via puTTY and over WiFi, it took 2-days of continued remote server code query, download, transfer, extraction, and installation ... Read More
RPi and TFT Touchscreen Integration with Linux

RPi and TFT Touchscreen Integration with Linux

The micro slot sensor integration module continues along its path. Today I integrated the Linux operating system and TFT display onto the micro slot module base station mockup. It was ... Read More
Frequency Selectability Experiment with Arduino

Frequency Selectability Experiment with Arduino

Here is a short effort to program the control of crystal frequency output. 8MHz as the standing frequency with multipliers asserted one at a time. This is an experiment to ... Read More
Stacked Power

Stacked Power

This power supply generally stacks underneath all SBC modules developed and for those to follow. It is supplied through a 120VAC detachable plug-in to an isolated receptacle. The circuit breaker ... Read More
