Soldering the resistor to between the power and data lines of the sensor cable can be a bit tricky. Especially if you want to connect more than one sensor to your Pi (as you’d solder the resistor to two power and two data lines!).
To make things easier, I designed a (very) simple board. It lets you connect up to five sensors, all you need to do is crimp the sensor cables with the appropriate connector.
Failing that, HenrysCat has kindly made the boards available on his storefront for purchase. This storefront isn't associated with temperature-machine but head over to Gitter to talk to HenrysCat direct.
For the temperature-machine in my lounge, I mounted it behind my TV and added some Pimoroni Blinkt! LEDs for ambient lighting.
