Laser Cutting Project: Bicycle hook

This weekends challenge, a better hook for a bicycle:

Want to laser cut one of your own or remix it? Check it out on Thingiverse

This is a vertical based bike hook for bicycles with aero (deep) front rims. Currently there are not many wheel hooks that keep the front wheel vertical and that don’t scratch the rim when putting the bike up.

The hook is lasercut using a glowforge and medium draft board (the material thickness is important as all the slots need to interlock). Assembly is slotting the parts together and installation requires two screws/anchors into the wall.

It was specifically designed for a Reynolds AR80, however, I believe other wheels with similar dimensions, depths or profiles should fit. read more

The puzzle of motivation

  • The puzzle of motivation – Daniel Pink

      • When – the scientific secret of timing
      • @DanielPink

      Here are a few key take aways from this short Ted Talk:

      Higher incentives led to worse performance

      Mechanical skills = the higher the skill the higher the pay
      Cognitive skill = opposite

      3 items:

      • Autonomy
        • Self direction works really well
          • Atlassian (Jira)
          • Hackathon
          Fedex days

        • 20 Percent Time
        • I think its something we have tried to encourage with “meeting free fridays”
        • ROWE (Results only work environment) – no schedules, just get the work done, meetings optional = productivity up, work satisfaction goes up

Generating Random Numbers with QisKit & IBM Quantum Hardware

paschmann

Generating true random strings using classical computers is not as easy as you may think. Unlike deterministic processes that follow specific algorithms and patterns, achieving true randomness poses a challenge in the realm of classical computing. Classical computers operate based on predetermined instructions and logical operations, which inherently lack the inherent unpredictability required for true randomness.

In contrast, true randomness involves an element of unpredictability that goes beyond the deterministic nature of classical computing. Attempts to generate random strings on classical computers often involve algorithms that simulate randomness, but these are ultimately constrained by the deterministic nature of the underlying hardware and software. read more
