3D Printing Project: F1 Sim Wheel

I have always enjoyed the concept of being immersed into a virtual world. One of my first experiences with VR was in roughly 1993 when our local arcade introduced a game from one of the OG gaming founders John Waldron called Dactyl Nightmare on a 1000CS. After that experience, I have always wanted to build a motion sim which gets you as close to reality as possible.

Last year I took the first steps and decided to put the initial blocks in place and start with sim platform that I could eventually add motion to. I purchased a Fanatic wheel base and thought it would be a great learning experience to build the steering wheel from scratch. Many of the components can be built versus bought which is what is keeping me motivated to eventually get the entire system together. read more

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

Printing Stickers

I recently purchased an Epson ET-8550 and a Cameo 4 for printing some fun stickers for myself, kids and friends. Here are a couple of things I have learned and some process related information I have been using.

General Process Flow:

Design in Illustrator, add inner and outer cut lines (on separate layers), ensure the border color has a bleed (if needed) -> export as SVG.

In Silhouette Connect, import SVG, Add registration marks, print out on sticker paper (Hide the cut lines layers). Apply any over laminate to the sticker sheet and load it into the Silhouette. Unhide the cut layers. And run the cutting using the Send function.

Cutting depth and force are very specific to the sticker paper and over laminate, so it’s a lot of trial and error.

Building a Passkit App

Building an Apple PassKit app has been an interesting endeavor. Internally at SAP we recently built a small Business Card application which allows employees to create a digital business card, and subsequently generate a individual and customized wallet pass, allowing them to quickly retrieve it, without having to find the app, and open it on their device. Having a wallet pass lets users simply double tap the lock button, authenticate and see a collection of their passes.

Open Source Project: Reach SDK

Over the past few years I have found myself re-implementing and re-writing basic features of server, web, mobile or service components. Registration, Login, Forgot Password, Notifications, Search, Help, FAQ, Contact Us, Maps are just a few I can think of, where half way through the development everything seems familiar and I have a case of deja vu. No doubt I have written or implemented a library or service which performs this specific function.

While developing the Changd app I found myself in one of the deja vu moments while writing the email notification service, and decided to pause development, and fix the root cause. After multiple Github issues to support a variety of notification providers, I came across Apprise, a python library which supports multiple notification provides. Since there was not a Node.js implementation, I decided to use Apprise as inspiration and influence for a Node.js library which I aptly named “Reach”. read more

DIY – Patent Idea – Spring Water Bottle Cage

Problem: In cycling (and other applications) water bottles are a variety of shapes and sizes. This often makes them difficult to get in or be contained in a traditional bicycle water cage. This attempts to resolve this by offering an “expanding” cage.

Fun but ultimately bad patent idea to create an expanding water bottle holder.

I made a couple models/3D prints to proof it out, but decided against it.

Excellent—thanks for sharing both the CAD diagram and video file. These materials are perfect for inclusion in your patent application as illustrative figures and demonstrations of your invention’s functionality.

Based on the visual references and the previous outline, here’s how we can now update the patent outline to include the new content and better illustrate your invention. read more
