Sheety Turns Spreadsheets Into Binaries, For Some Reason (opens the original)
Read excerpt
Ever wanted a spreadsheet as an executable with a built-in terminal interface? No? Well, that’s a pity because [Roberto Alsina]’s Sheety project does exactly that. Sheety compiles spreadsheet definitions into a self-contained, executable binary with zero runtime dependencies. It presents a simple terminal application (with mouse support) in which one can browse and edit data and formulas with a simple interface. As far as formats go it can import and export Excel files, or a human-readable .yaml
Enormous Fluid Simulation On Flip Dots Is Also Enormous Amount Of Work (opens the original)
Read excerpt
Flip dot displays are cool, and more people realize that after [mitxela]’s fluid simulation on flip dots installation was on display at EMF 2026. As glorious as the result is, it was also an amazing amount of work! Not only did [mitxela] need to source a large number of flip dots, he also needed to find a solution for driving them that didn’t end up more trouble than it was worth. Just about everything about the surplus flip dots — from electrical requirements to mounting — was a pain to work wi
Easy Ways To Sink A Hardware Startup (opens the original)
Read excerpt
[Ryan Walker] may have written up his observations a few years ago, but the lessons are just as relevant today as they were back then. He shares five easy ways to sink your hardware startup. It’s a reminder that while hardware startups are unique, there are basic business realities that still apply because the hardware itself is going to be only one part of a whole. These business fundamentals can be a drag, but it’s worth giving them some attention. But if that’s not your jam, no worries. As [R

Robot Makes Literal Daisy Chains (opens the original)
Read excerpt
[Jude Robinson]’s robot Daisy has an unusual function: making a literal chain of daisies. The device is his student final project and demonstrates how a system can replace sensing with clever mechanical constraints. Instead of bringing tools to bear on each daisy, the daisies are brought to the tools in a repeatable, deterministic way. Daisy is essentially two X-Y gantries with grippers facing one another. Between them is a conveyor upon which daisies are fed, plus a blade at the top with a thre
