 I just bought a Hitachi VC-6025 oscilloscope from my Singapore trip for 85 SGD. It's a good deal, since there is not a lot of second-hand electronics auctions on Ebay Australia, and the shipping costs from overseas or even interstate make it not very economical.

 I recently purchased [this DC block](https://www.aliexpress.com/item/1005002575850555.html) from Aliexpress to protect our HP 8560A spectrum analyzer. I did some basic tests on the DC block and it looks good for the price. These N type DC blocks seem to be less common and twice as expensive than the SMA type, but I wanted to avoid using SMA hardware for my setup.

 As part of the [Neptunium flight computer](https://www.petertanner.dev/neptunium/), I wanted to create a proper webpage to showcase the flight computer. This will also be a landing page for people who want to use the wasm powered Neptunium Explorer, which will allow users to analyze flight data in the browser. At the center of this webpage I want to show an interactive 3d model of the flight computer
