Robot Army : Printing + Drinking

Nitrogen Capsules = LED Diffusers

Here’s a St. Patricks Day story for those of you who are into that sort of thing. As you might have gathered, Mark and I like to drink beer while we work. Lately our brew of choice has been Guinness. We’ve been so busy now that we’re in fulfillment mode that we’ve neglected to haul our empty beer cans from the past two or three weeks to the curb. There is a mound of them piled in the corner of the kitchen waiting to be tripped over.

In short, we haven’t had any luck finding a more reasonably priced lens to go over the LED of our robots. The one we had found, though perfect in size and shape is freakishly expensive (We’re talking several times more than the amount we allocated for that part on our BOM). We had given up on finding a replacement for now, when this Monday on St. Patty’s Day Mark was making bacon and needed a place to pour off the grease. No doubt, an empty Guinness can was in reach… so he chopped one in half to use. Inside of the can was the little nitrogen pellet-ball thing that releases the gas once the can is opened. Would you believe that this stupid little white ball when cut in half at its seam is the EXACT size, shape and thickness we need for our lens? It even has holes on the sides for mounting. The best part of this discovery is that we already have 9075629081863587 empty Guinness cans lying around with little capsules inside waiting to be harvested. I hope some of you out there can appreciate how hilarious and awesome this is. How’s that for hacking and being environmentally friendly?

Like pulling pearls from an oyster :

We aren’t sure if we’ll actually end up using them, but we figured since the universe handed us this coincidence, we’d give it a shot and see how they look with an LED inside. I’ll post pictures once I have one on a delta.

One-Million Yellow Arms

In other news, I’ve printed more yellow arms than I can count. We just received our money from Kickstarter today (over two weeks since the end of the campaign), so the first order of business was to buy more filament. We’re well on our way to producing all the parts we’ll need… but this first batch will be used for our own installation coming up in April.

Hexagons. They’re everywhere.

The Mini Maker Faire here in Vegas will be a test run for all the various elements in our installation. Jeff helped me cut the first wooden platform on the ShopBot last Monday which will house the deltas at a safe distance from one another so they don’t clash :

If the design works out nicely we’ll need to make six of these total before the big Maker Faire in May. I’m thinking the design will need to be revised a little, but this is a good start! The hexagon design is quite fetching :

This week we sanded and primed the base for its fancy paint job :

We sprayed the finished piece a flat 50% grey. I plan on painting the hex ring bits that hold the robots in place a slightly lighter shade, and the edges will be a darker grey to give the base extra depth :

Since I’ve adopted the honeycomb pattern… I started seeing it everywhere. Mark and I spotted this while running errands :

It might seem like my yellow robots in their massive numbers nested on a hexagonal grid is a metaphor for bees. Hmmmm…. This occurred to me a couple of days ago while I was sitting outside having a glass of wine when a bee decided to land on the lip of my glass and take a dive. Mark scooped the bee out and set him on the ground to dry off. He was stained pink and rather uncomfortable seeing as he was soaked in stinging alcohol. He hobbled around while rubbing his little face with his bee hands… so Mark and I talked to him until he dried off and finally sobered up enough to fly away. We made a new friend.

This week I’ve been switching out all the old parts of my original prototype deltas for the new generation of parts that will be included in our kit. Once everything has the latest and greatest hardware we’ll see how the kids performs at their first live recital at the Mini Maker Faire. =] Delta Do!

Again, if you haven’t liked our Facebook page, you should!

And if you happen to make robots yourself- get on our forum and brag about what you’ve done. Now. ❤

Oh, I’ll leave you all with this… So! It was my birthday this week and the night before I had an interesting dream. Now, I haven’t played WoW in years, but for some reason I dreamt that there was an event for my birthday which was causing people to get a delta robot as a pet in game. While I ran around as my paladin, everyone had tiny delta robots hopping behind them everywhere they went. It amused me. I may have to animate this…
