DropBOB PRO “Hit-Single” release


So I’ve been back from holidays for about 2 weeks now, what do I have to show for this? Well, to be honest, not as much as I’d hoped. I’ve actually been struggling with a little bit of mild anxiety. This all started sometime while I was in Europe on vacation. I didn’t know it at the time, but it turns out Nasonex (a nasal steroid for allergies), has some side effects that actually affect me. Anxiety is not something I have ever really had. So it caught me off guard.

I’ve stopped using the spray for about 2 weeks now and the anxiety is almost completely gone. It only pops up if I don’t sleep enough now. This made me a little more aware of what people who suffer from anxiety feel. It’s not fun. It makes you doubt even your own rational thoughts. My anxiety was actually centered around “being stuck somewhere” … like planes, or even a restaurant. Anytime that I would be forced to not move, whether because of norms (like at a restaurant or movie theater), or in a plane or bus, my hands would sweat, and if I thought too much I would actually get a full on panic attack where my chest would feel warm and my heart would beat faster. I managed to keep it under control though.

DropBOB back from Holidays, with a new bean!


And were back! What an amazing holiday. Hope you had fun following some of the Instagram pics and facebook pics I posted from a few parts of my trip to Dublin, Lisbon, Prague & Barcelona!

I picked up a little something to try out just a few days before our return. Freshly roasted coffee beans from a tiny little gem of a place in Barcelona. This small place is tucked away in the windy cobblestone streets/alleys.

DropBOB Upgrades to “Real-Boy” Status!


So as I hinted from my last post. I have decided to delve right into the world of professional software development. I have started using “Eclipse” as my development platform for my IoT chip – ESP32 by Sparkfun.

To be fair, I didn’t really have a choice. Not all of the features that I need this chip to do have been ported over into the “Arduino” platform yet. I’m sure it eventually will (possibly more than a year, as seen on the prior chip). So, I’m pulling up my big boy pants and learning all the things!

I will be keeping my software open-source. But it will be via the official ESP-IDF. Once I program for this (in C language) I won’t be porting it back into Arduino (Sorry arduino fans).

DropBOB Designs: learning a new skill!


So I’ve been wanting to do this for a few years now, but I’ve never had the patience to really devote some time to it … Until now.

I’ve been learning circuit board design and component selection. I’m hoping to not only simplify the entire wiring design for my cold brewer. I’m trying to expand its capabilities tenfold.

DropBOB PRO – Preliminary design update


Some of you may be wondering what I’ve been up to over the last little while. I haven’t posted anything, nor have I put my “Star-Lord” Costume up for sale. Well, it’s because something has been bugging me. I’m unsettled about one of my designs … and its preventing me from focusing on other things. 

As you can see from the above image, I’m working on a PRO version (i.e something you’d see in a coffeeshop or a coffee enthusiast kitchen). All, while improving on the DropBOB control mechanism.

You see I’m no longer just happy with having the most accurate and flexible cold brewing drop control on the market. I want more! … I’ve added temperature control as well now. With a little bit of testing, I’d like to not only be able to have my drops colder, but also hotter, all at the slide of a finger on your smartphone.
I’ve also added a second photo-interrupter for a drop anticipation feature. And I’m getting rid of the Long neck that hung below the water (that was a standard plumbing parts restriction) … I’m also designing my own valve … And making the glass custom. Oh, and making dishwasher friendly.
Ya, I know … this is ambitious. Here’s to 2017 being the year “DropBOB Designs” takes off. I hope.
Cheers,
-D.B.

DropBOB(tm) Designs, Short-term Roadmap: Current projects


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) Designs – Open for business!


DropBOB(tm) Designs is officially open for business. I have been terrible at blogging lately, but this is only because I’ve been busy at work. Check it out:
DropBOB(tm) closed loop drip system – Industrial style in Large
If you haven’t noticed already, I’ve opened up my shop in the form of a Blog with a cart to the right. Feel free to browse my wares. Many of the items can be modified and configured as you like them, right from your browser. I will be adding more options shortly.

I’ve also expanded myself and have started selling on Etsy. Check out my Etsy Shop here. I’m also on facebook at DropBOBdesigns, Like my page!

The personal version of the DropBOB(tm) closed loop drip system is currently in beta version #3.5.0 but it is out for production. Any sales of the beta version will have its features upgraded to the final version at no extra charge.
Also, feel free to add come custom notes at checkout, as these are all hand made, I can probably include any custom features that you may want. Want the base marble? I might be able to do that. Want galvanized pipe? Want aluminum? Etc. Note that these extras will be quoted on a job by job basis.
On another note, DropBOB(tm) designs is not only for personal coffee drip systems. DropBOB(tm) designs is more of a mantra for unique well designed products. Handcrafted and meticulously assembled. A place where Art meets function.
Here’s a sneak peak at my next project:

Closed loop drop-BOB: the only cold drip coffee maker you can count on!


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.
