This is a switch-mode PSU, so the mains is rectified to around 400 volts DC inside. Extra care is required to avoid touching this dangerous part of the PCB.Instruction manual:EX354RD+EX354RT_Instruction_Manual-Iss6.pdf Fault: Not marked on unit. Suspected...
I have a Photovoltaic Solar Array on my roof, and as a nerd I just can't NOT know how it is doing up there. Bureaucracy being what it is, it was installed in the summer, and I didn't get Permission to Operate from the local electric company...
Calling a Web Service isn't too difficult and with the SolarEdge documentation and Postman I was about to talk to the system right away. Really easy API Key based system. I would feed the same API calls into the Pi Pico W and it would scream about security....
On a whim I decided to put a LILYGO T-Display S3 into the mix and see if it didn't behave better. The code shouldn't require a change between hardware platforms thanks to the hardware abstraction layer in the Arduino development platform.I hit upload...
I was having great success with the basic request for the current status. Things were working great. I wanted the 15 minute updated production history. This required a start date time and an end date time.Every time I attempted to call that API...
Done in a weekend. Finishing a project isn't a luxury I often get, and doing even a simple one in a weekend is nice. The source code can be found here: https://github.com/AardvarkMan/SolarMonitorI'll 3D print a case for it later, but from a code...
Just received the new version of the balancing robot PCB with key improvements – correct connector orientation and streamlined design by removing unnecessary parts. Stay tuned for more updates!
Finally, I assembled the robot and did the first tests. Considering its size and DC motors with huge backlash, the robot does a great job keeping the balance.

Made a list of the most common communication interfaces used found in job descriptions for Electrical/Hardware positionsGoing to use PCI/e, HDMI and USB for sure, may also use SPI or I2C, we will seeCurrent interconnect plan:Not sure if I will SPI, I2C...
It is big... The daughter board on the left has a ROM that seems to hold the patterns. It uses an SAA1043 universal sync generator. A module can. An 8085, 8155, and EEPROM. The 8155 contains 2K of RAM. 4012 110 10812 Digital Board For PM5515: 4012 110...
Monitor App The Pocket Pad does not have any spare pins for peripherals, however, it does have bluetooth which can be used to connect to external devices and sensors. I had already made a Seeed Studio XIAO NRF52840 based environment monitoring station...
Video shows creation and execution of the traditional Hello, World program. Executed first from Editor App and then as an App in its own right. Typing is painful as usually I use thumbs with this keyboard but to keep it in focus it had to be flat on...
