NickStick Design

NickStick Design is a small scale mechatronics design studio based in The Netherlands. Over the years we designed and manufactured a variety of (partly open source) products. Earlier projects include SwarmDrive , RF Power Snitch and ConsoleCast . Sizable7 is, as other creations, born out of necessity and lack of suitable, readily available solutions.

Other products


We needed a large 7-segment display which can be used without the need for a separate enclosure. It should look good on its own and it had to be modular (expandable use cases). Also we were looking for multi-color (RGB) and if possible addressable pixel displays. Although there are several matrix displays available we needed a more conventional digit display unit. It turned out that there were not many suitable candidates available and so we started the design of Sizable7.

Use cases

We soon recognized that there are still many use cases for conventional digit displays. Of course a clock (with Sizable7 a huge clock) comes to mind first. But think about scoreboards or timing displays for sporting events or these large price boards you see at gas stations. Some production facilities or other workplaces keep track of numbers or counters that should be visible at distance.
We realised that Sizable7 could be a perfect solution for many of these number or counter applications.
