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 in my case 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 […]
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: open-drain outputs and higher total current-sinking capability – 400mA vs […]
When you spend anytime 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 ‘Klemmenbezeichnungen’. […]
In the UK if you want to place a product on the market you need to ensure that it has a UKCA mark and a DoC, there are a number of things that need to be done. Looking through the list, we have UKCA / CE, RoHS, WEEE, and LVD. […]
Capacitors are used to “Store electrical energy”, along with Resistors they make up two of the fundamental components used in electronic circuits. Capacitors – Use Capacitors are used in several different ways in electronic circuits: Used to store charge for high-speed use or as a back-up supply in case of […]
First, we are going to cover some basics in this case Resistors, but, to do this we are going to tell some lies, if you know what the lies are, then chances are that you don’t need to read this post… but please do anyway. Resistors’ values are measured in […]
