Hardware

I’m currently in the process of building a computer based on the 6502 microprocesser, following Ben Eater’s instructions. It’s a nice way of learning the lower level parts of a computer by wiring up and eventually coding everything yourself. In this post I want to share my (more or less structured) notes of the steps taken and lessons learned so far (covering part 1 to part 7). While my notes were mainly created to explain things to myself, I hope you can get some value out of it as well. ...

I got myself an Aranet4 device to monitor CO2 levels in my office. The monitor gives pretty accurate readings and has very low energy demands (due to the e-ink display) (here’s the datasheet). While the intended way to read the measurements is to use the mobile app, it’s always good to be able to access the raw data yourself; you get to store as many readings as you like (otherwise limited to past 7 days) and can analyse them in any way you want. ...

I recently bought an Intel NUC8i7HVK to work as an ESXi host. In this post I walk you through the process of installation and initial setup. Hardware The NUC8i7HVK is the top-of-the-line model of the NUC kits and comes with an i7-8809G processor. It ships with neither memory nor storage, so picked up the following additional components: 2 x Samsung 32 GB DDR4-2666, SO-DIMM (M471A4G43MB1-CTD) 1 x Intel SSD 660p Series 1.0 TB, M.2 80 mm (SSDPEKNW010T8x 1) 1 x SanDisk Ultra Fit 16 GB (SDCZ430-016G-G46) An interesting fact to note: in the official specs, Intel mentions 32 GB as the maximum memory size. However, with 32 GB sticks now readily available and 64 GB being listed as the maximum memory size for the i7-8809G, I gave it a shot and installed 2 x 32 GB of RAM. It worked without issues. ...
