Building up Ian Hughes’ K9 Body
Ian Hughes has done a lot of work on making a 3D-printable K9. Details of Doctor Who’s K-9 and other science-fiction models can be found on his Patreon page. I am currently working on printing the external parts for the…
EMC Charts and Graphs
Plotting EMC limit charts in Microsoft Excel is unfortunately quite hard, Standards like CISPR 11 and CISPR 25 make use of Log/Log graphs.
Adding SCPI to Arduino Test Equipment
Make an item of test equipment that can respond to SCPI (IEEE-488.1) commands. including *IDN?, *OPT? and *TST
Hardware Version Numbers
To encode the Hardware Revision number, so that we know what the version numbers of the main PCB is and is available to the Microcontroller.
Arduino Serial Number
we use the "ArduinoUniqueID" Arduino library, to give us the Unique ID serial number of the Arduino we are using.

Storing when an Arduino sketch was Compiled
It is helpful to know when the firmware on the device was compiled, it can be displayed on a screen, or sent viewed over serial.
Reducing Ripple on DC lines
After AC Rectification, the next step is Reducing the Ripple on the DC supply line as much as possible.
Alternating Current Rectification
AC (Alternating Current) is used for the transmission of mains voltage, one of its main advantages for use as a method of transmission over DC (Direct Current) is that a change of voltage between High Voltage, Low Voltage, and SELV…
EV Connectors for BEVs, PHEVs and EVSEs
For the Charging Two EVs on One EVSE project, I will need a Vehicle Inlet ‘Male’ type EV charging connector for the upstream supply from the existing EVSE. And two EVSE ‘Female’ type EV connectors to allow for connection to…
