Micro-Slot Build of Physical Timer Prototype
Completed first build of revision A. The new PCB fabrication company turns out okay so far. Comes from the U.S., less money and faster delivery. I still have to debug ... Read More
Prototype Micro-Slot Module & Proof of Concept
Unraveling nested nodes to get the prototype unit fabricated and built. It's inevitable, jumps and via's shall be sprinkled throughout to overcome the entanglements. This is the first micro slot ... Read More
Programmable Pulse Timer Concept & Design
As more circuit builds come about, they're increasing in density. Bought the parts. Gerber files, drill codes and netlist off to the fabrication house now. The programmable timing module design ... Read More
RPi Sensor Station Prototype Evaluation and Debug
Today I finished the RPi 3 shield station prototype. Designed it, built it and the system works right from power-up. All the sensors were loaded and came online. The unit ... Read More
LED Illumination Control with Arduino Uno
There was an online guide that walks a viewer through how to assign color variable values in code to red, green and blue. To combine each as having relative color ... Read More
Power Supply Assembly for SBC Modules
Here is the power supply I made from scratch to support the various modules developed so far. With more to come, this unit is sure to prove useful again and ... Read More
4-Channel Signal Relay Board for SBC Modules
This is a video walk-through about a 4-channel contact closure relay module I made. An example application is demonstrated here by driving a micro-fan through a relay and connector signal ... Read More
Signal Interrupt & Ground Lift Board for SBC Modules
This is a video that explains the purpose and function of the signal interrupt module. This was the first module I developed and made as an effort to get familiar ... Read More
Active Thermal Control for SBC Modules
This is a single-board computer (SBC) thermal management module loaded with variable controlled fans. Two manual settings for each fan at either high or low, provide for a steady level ... Read More
