Creating a custom leaflet marker, part 2 – Making it more self-supported

In this post I’ll discuss the Leaflet marker in more detail and give it some internal functionality. If you haven’t read the previous post you can check it out here.

If you’ve done previous work with Leaflet you’ve probably created some great viewmodels that have functionality to drive the markers. In my first attempts to create map based modules I just followed the regular tutorials and some freely available plugins from the Leaflet plugin repository. After some iterations on the functionality we had created a monstrous JavaScript file with lots and lots of methods driving the markers. Add to that the performance issues we found when creating and destroying large amounts of markers, so the time had come to restructure the code.

Creating an animated leaflet marker with CSS transitions and sprites – Part 1

So for my first real dev post I thought I’ll do a write up on a little project I did a while back. Doing stuff on a map is a big chunk of the functionality for a lot of the applications we build. Handling large numbers of markers and mutating them is mostly part of that deal as well.

For the sake of legibility I’ll split this up in three parts:

Welcome to the wonderful world of me

As you might have guessed from this website’s title, my name is Jeroen. I am a husband, father, developer, designer, creator, geek and lover of many things, which usually also involves writing a lot of code. I live and work in The Netherlands (yes, where Peter Pan lives) and if I had to describe my skills in a couple of words I’d say I’m pretty much an all-round application creator.

So that’s the short answer, the long answer is I’m intimately familiar with a lot of disciplines and technologies. Knower of all, master of none, some might say, but in most cases I tend to dive just a little bit deeper into a technology than most. And that’s where this website originated. In my many endeavors around the web I’ve come across countless tutorials, articles and stackoverflow questions that handle the basic scenarios. But there are precious few resources out there for people like me, or in my position that deal with creating large scale line of business applications using the latest technologies.

In the meantime I’ve also built an Iron Man Mark IV mask and some Minecraft stuff with my eldest daughter ๐Ÿ™‚

Venturing into Pepakura

One of the events on the agenda at the moment is the 2015 Dutch Comic Con in Utrecht. Inย going over some cosplay ideas for me and my brother I was looking at some YouTube build videos on helmets. The series I found particularly interesting was Boochieboys‘ Iron Man helmet build. Not that I’m going to be building anything near an Iron Man costume, but the build method peaked my interest.

A primed example

This weekend I continued work on the legs for my little R2 unit. As was very noticeable in one of my previous posts, my woodworking skills aren’t really up to snuff yet ๐Ÿ™‚ The cut out legs were a little rough around the edges.

I picked up some polyester body filler (mainly used in car body repair) and filled, and sanded, and filled, and sanded, and filled, and sanded every part three times till I got a nice smooth finish. I then primed the parts with a spray-on primer (the same I used for the dome panels). 20140519_185952 20140519_190012

And voila, here is the result after a single coat of primer. I will be doing some more smoothing and priming it again before the paint can go on though. With the main structure of the legs all done, I can move on the all the tiny details that go on the legs now, as can be seen in an even earlier post of my 3D drawings.

 

Do or do not, there is no try

Last week we had a vacation over at Disneyland Paris, and lo and behold, they had a Lego Store! So like any kid in a candy store I went back three times ๐Ÿ˜›

Scroll, scroll, scroll your saw

Today I took out my scroll saw and started work on the legs. I wanted to make them out of a material that would support the R2, so instead of making them out of plastic or some faux wood, I made the from solid MDF. So I cut out the first parts out of 18mm and 12mm board. Granted, they are still in rough shape, but the basic form is done. Next I’ll be patching them up and smoothing them out with some polyester body filling, or Bondo.

Props wish list

As the R2-D2 project is quite a substantial one, I’ve also been thinking about some smaller projects I would like to pick up eventually. Here are the smaller props that I’m thinking of right now. Please leave me some suggestions if you have any cool ideas for smaller projects in the comments below.

A leg to stand on

It’s been a while since the last update, but with good reason. Over the last couple of weeks I’ve been working out my little R2 as a 3D model to get a grip on all of the dimensions and individual parts involved. The first pieces I will be working on next on the build itself are the legs. For now a couple of screenshots of the legs will have to do though ๐Ÿ™‚

I’ve used Sketchup as my 3D modeling tool of choice. It isn’t a very accurate 3D modeler, but for architectural designs and models it’s a wonderfully fast tool. And best of all, it’s free! By using the 3D model I can easily get all the measurements I need on three axes in stead of two from a regular old blueprint. It also helps me comparing it to the reference photos I have to get as close as I canย to the real thing.

Also I have adjusted the measurements slightly to fit the standard MDF board thicknesses I’ll be using later on.

For now, here are some screenshots of the legs:
