Bicycle Computer Mount For Bar End

This is a bicycle mount for a computer and a display unit of an ebike. It has 22mm and 32mm tubes to which computers can be mounted. The mount goes into the bar end of a steering wheel. This is paraticulary useful for recumbent bikes. The mount is designed for M5 nuts and bolts, but depending on the accuracy of your 3D printer you might need to use M4 bolts. You can download the 3D files over at GrabCAD.

Here is a technical drawing of the design:

LEGO Resin Casting Brick in a Brick

This video will show you how to create your own LEGO bricks that enclose other LEGO bricks. I used the polyester resin pouring method to create the brick by utilising a silicon based mould. These step by step instructions help you to create your own LEGO brick. This is an ideal present for all your AFOL friends.

Here are some more photos of the models I made:

Visual Metaphor Gone Wrong

UC uses wrong design for cyber security campaign.

The University of Canterbury is making an effort to increase awareness for the need of strong passwords. For this purpose they ran the “Longer Is Stronger” campaign, including a poster that is still being shown on displays across the campus.

The problem is that the visual metaphor of a chain is completely wrong. A chain is only as strong as its weakest link and with an increasing length of the chain the likelihood of a particularly week link increases. A longer chain is weaker than a short one. I really hope that our IT security experts are smarter than our visual designers.

A password is indeed usually stronger the longer it is. Encouraging students and staff to use long passwords is a step in the right direction. It would be even better if UC would offer password managers, such as 1Password or LastPass to all its members. That way our passwords could not only be long, but we would be able to conveniently access them. But putting money where you mouth is, is a skill that UC still needs to practice. Purchases of password managers are still being processed on an individual basis and it can take months to complete a purchase.

New artwork for LEGO 18836pb04 shield

A drawing of the 18836pb04 LEGO shield.

The LEGO Classic Castle shield 18836pb04 is part of the collectible Minifigures series. Time to create a new drawing of the artwork. I have to find a way how to incorporate this new shield in my previous poster and t-shirt.
