I have recently had reason to try out Rapid Harness to draw harnesses for assemblies, I found Rapid Harness to be a bit clunky; A fair while ago I came across WireViz via Hackaday and decided to give that a go for CADing up the loom drawings. WireViz is Free […]

You may have heard the saying “never trust the autorouter”, you may have even seen it written on a t-shirt! Back when I used Eagle ECAD (Before AutoDesk did their thing), there was a built-in autorouter that was a handy tool to use to help with working out if you […]
In a previous post, I talked about the MCP23017 and MCP23018, and why the MCP23017 was a better device for my use in this case (this case being my Remote control K9). The MCP23017 can only output a digital high of the same voltage as VDD, which is capped at […]
In my previous post, I talked about some of the advantages of the MCP23018, and how it was easier to address… Well, it turns out that I made the standard mistake of not reading the datasheet… It’s not as though the MCP23018 obscures the lack of current source deep in […]
The MCP23017 is a popular I2C 16bit IO module, it can be used to allow you to have more GPIOs available, There is also the MCP23018 available, which does fundamentally the same as the MCP23017, but with a few differences: On an I2C bus, each device has a unique address, […]
When you spend any time more involved with vehicles than reading a Haynes manual at some point you will need to know what someone means by KL31 in regards to automotive wiring for 12 V vehicles. ‘KL’ is the abbreviation for ‘klemme’ which is the German term for connector/connection, or […]
In the United Kingdom, if you want to place a product on the market you need to ensure that you have a CE mark, this is fundamentally the same as the now deprecated UKCA mark. The CE mark will allow you to sell in Europe. Please see this post about […]
Capacitors are used to “Store electrical energy” along with Resistors they make up two of the fundamental components used in electronic circuits. An ideal capacitor should have neither inductance nor resistance. Capacitors – Use Capacitors are used in several different ways in electronic circuits: Charge and Voltage A capacitor is […]
