DropBOB Designs now with 50% more dimensions!
I’ve been working on upgrading my cold brew coffee maker for the PRO scene. I wanted a more robust and flexible model and I think this going to be my next prototype. Feel free to grab the model below and rotate and explore! I’ve designed this with the user in mind and I wanted a fully interactive user experience, right out of the gate! No holds barred!
So, as you’ve most likely seen, I’ve managed to create and release a functional and super connected cold drip coffee maker that is more accurate and versatile (and some would say better looking) than any out there on the market …
|DropBOB(tm) Coffeeshop version Idea|
But that’s not enough. This is great for personal use … and I do use it weekly, but there is not enough desire for this product yet. So this is where the next step comes in. With this fully functional proof of concept in mind, I need to design a “Coffee-shop” version of the Personal DropBOB(tm) Closed loop Cold Drip Coffee Maker (I need a catchier name …)
The idea is to be able to produce a model that can keep up with the demand of a coffee shop. Most coffee shops need high volume output, so they resort to the “Bag of grinds in a bucket” method. This is functional, but highly susceptible to variation in strength and taste, and also a huge drain on beans (read not efficient at all!).
So, My idea focuses on increasing throughput while not affecting the quality and accuracy of the system. Adding more drippers, with more coffee bean silos allows the process to go faster, but still keeping the same concept and quality. And by rotating the grounds one silo every 8 hrs, you get a perfectly consistant brew throughout the day.
The idea is that a coffeeshop can have 3 to 10 of these beauties lined up on a wall, with different beans, and flavours. You can have some with added spices, or oils. Essentially creating an infinite possibility of flavors!
This design is not complete yet. In the meantime, you can purchase an individual version of the DropBOB from my shop, just click the cart items on the right and customise your order as you like!
I’ve also added a community page (Click “Community Stories” above) for anyone to share their experience and/or hacks! feel free to let me know what you think in the comments.
|DropBOB(tm) closed loop drip system – Industrial style in Large|
So I’ve completed my design. I’ve converted my 3d printable files to STL files and have sent them off to the printer: www.3dhubs.com. fingers crossed that everything comes back nice … you never know with these types of “compact” housings… Plus this is my first functional 3d print … Everything else I’ve done in the past was not as critical.
With this initial beta release, I can control my coffee maker from anywhere. I can check the progress of how it is doing. and I can adjust the flavor profile depending on how many drops per minute (DPM) & grind type I use. And I can know that it is always exactly where I want it because it’s a closed loop system with constant feedback.

Oh, and also, since my idea is to eventually release this into the world with huge potential for modifications and improvements, I’ve shared my code on my GitHUB. Feel free to make improvements. make comments, or even suggestions that I can implement (note, I’m not a software guy … I juts do this for fun. So go easy on my code).
So I’ve almost completed the head part of this costume. And since I’ll be attending the Vancouver Halloween Parade, I have to make sure not to put any gore and blood on it as its a “family” oriented event. But don’t worry, The gore will be added after this.
Since last week, I’ve added mesh & cast iron pipes & foam.
I started trying to screw in the mesh with fasteners and washers … but it was actually way stronger and faster to just hot glue it.
The foam was glued in using my favorite glue: PL 8x I haven’t yet found something this glue can’t do! It’s low odor and does not melt foam (most glues do this because of the acetone).
With these major upgrades the head already looks badass!
Drinking always gets those creative juices flow!
Adding some of these Cast iron union joints (these are my favorite parts, they just feel really good in the hands).
And since the structure is build with 1/2″ plywood, attaching anything is simple.
Adding the foam strategically to fit your body is key!
Now that you have the whole thing built up. Adding some paint just makes the whole thing POP!
After a little bit of searching. I found that the best color and style for this is the Hammered Brown. It gives it a cast iron sheen and gives it a galvanized texture. Perfect for this project!
The mandatory painters tape!
And after a few complaints from the smell coming from the wife … and voila. Let it dry overnight and you have yourself a metallic looking helmet!
Now to make the rear wiglet looking things. Note, that I could have left these out as they are pure aesthetic … but no. I go all the way!
And since I only want it to look like the bolts actually bolt right into my spine … I’ll end up cutting these.
Ya, I love sparks! I know.
Using the PL glue again, you can add to this piece.
And that’s what it’s supposed to look like once installed. And, to give it some extra emphasis … I’ll actually keep these metallic silver (galvanized).
And don’t forget to paint the interior foam black … makes it look professional.
Up next: Don’t forget the most important part:
Up next, install the red gear, buy material for the bottom of the costume (the pants), and make the ginormous sword … standby!
So, this year, as every year. The time has come to spend way too much time on a Halloween costume.
If any of you know me, I hate to follow the masses and purchase a pre-cooked costume from the evil companies overcharging for costumes because they know the general population is too lazy to work hard for a costume.
Here are some old costumes of mine from the years past:
So what can I possibly do this year? Seriously … Its already Oct 2nd … I’m way behind schedule … I only right now decided what I will be and I’m only picking up some of the material staring tomorrow …
Do you think I can do it?
I have a work function Halloween party … so this year I will have added pressure for the deadline.
Here’s a hint at what I’ve got so far:
As promised, my render has finally finished. I had to redo it a few times since I had missed just a few details. I think you’ll like it. Actually only started the render last night at 3am. I had some trouble getting the lighting, shading and floor height just right. Turns out that a refractive index of 1.5 makes the insides of your car look like a fishbowl. While that might be cool, it doesn’t really portray what I’m looking for.
