Various topics of interest appear here to highlight project activity that is technical in nature. These posts are about subjects and accomplishments at a substantive and abstract level of learning or interest. From hardware, software, and systems to other areas of learning, there are subjects here concerning ongoing personal and professional interests.
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
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
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
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
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
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
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
RPi Shield
idXR.010 specifications served up. Deeply satisfying making these technologies. This time I made a break out assembly for a Raspberry Pi 2. Also with the same footprint as the Raspberry ... Read More
Arduino to RPi Code Origination, Conversion & Test
Tonight's successful concept test with Python conversion from Arduino to Raspberry Pi. Happened to find the experimental Arduino code to drive an external sensor module. For it to behave as ... Read More
