DropBOB(tm) DESIGNSProduct Manual

DropBOB Designs is a business, naturally evolved from the love of great designs; from the lack of designs in the marketplace that fulfill a need that cannot be mass produced. DropBOB Designs is devoted to unique and handcrafted designs. A small scale business with grand ideas!

SpaceshipContraption

Water Towerw/ DropBOB contraption

Black Steel Pipe

w/ Coffee in FunnelWater Bottle

Solid Wooden BlockWith Epoxy Pocket

Physical build

Begin by opening the packaging and disposing of the environmentally friendly packaging (Please recycle)

Once all disposed of, screw the Black Steel pipe into the wooden block until tight. Don't worry, these are compression threads, they get tighter as you screw in.

Now, make sure the 4 feet of your block are level with the surface you want to put it on. They screw in and out.

Now take the Black Steel Tee that is connected to the 3-d printed "spaceship" looking thing with a red valve handle. unscrew the handle until you can fit the Tee over the steel pipe. Adjust to desired height and then tighten the red valve handle.

Now place your "water-tower" on the plastic "spaceship" contraption, with official "DropBOB(TM)" contraption (the square cube of "Insert Colour you purchased here"). Note that in order for you to do this you will need to slide the 1/8" brass tube through the allotted slot in the "spaceship".

There, the hard part is done. Please pat yourself on the back.

Now you can place the bottle in the pocket. Wait, first, slowly rub your fingers on the blue surface created by heating Molten Epoxy until the wood fibers explode with joy at just the right moment to lock the happiness into its forever solid (and smooth) surface. OK, now place the bottle in the pocket.

Remove the Eco friendly Cork and place the white funnel in the mouth of the bottle. Take some grounds (Recommended dosage is the equivalent of 1 espresso Spoon --- equivalent = 2 tablespoons = 30 ml --- per cup that you plan to make) and place this in the provided thin mesh re-usable filter (hand wash only). Now place a small paper tissue (Scott Towel) on top of the grounds (this is to make sure the drop doesn't just make a hole through all the grounds overtime). Now you can place the filter/Coffee-grounds/paper-towel assembly directly in the Funnel. It should be a perfect fit.

Now plug the provided USB cable with power converter into the wall and the micro USB end into the side of the "DropBOB(TM)" cube.

You should hear the servo turn to position, and shortly should see some drops coming out. This is normal, don't panic. Just hold onto your towel. If you can't find your towel, then you haven't read enough sci-fi books.

At this point you should also notice the blue blinking behind the "DropBOB(TM)". This is normal, This indicates that the device is calibrating. This calibration process could take several minutes. It is slowly closing the value until the desired Drop Per Minute (DPM) is reached (Default is 6). Also notice the toggle switch. This switch has a (on)-off-(on) configuration. The brackets mean that the switch will not stay locked in that position. Pushing the switch down and holding for a few seconds should put your device to sleep and close the valve as well (helpfull for refilling). Pushing the toggle upwards will wake the device and start the code running from the top (note here that attempting to wake the device while already awake will force a restart of the code ... how would you like it if someone tried to wake you when you were already awake!).

The control logic embedded into the ESP8266 make it so that any disturbance is "naturally" brought back to a steady state. Any errors or issues, should always automatically self correct (over time ... some large disturbances may take several minutes, up to an hour even if you really screw with it). Now go enjoy your day ... you've read enough ...

Connecting the DropBOB(TM) to your wifi & Phone

Download Blynk from Android or Apple stores for your phone. Open the app, Create New Project, make sure the "Hardware Model" is set to "Sparkfun ESP8266 Thing" then tap on the "AUTH TOKEN" and it should automatically copy it to your phone's clip board. Click Create.

Now Make sure your DropBOB is plugged in. After a few seconds it should start broadcasting an Access Point that you can connect to from your phones wifi (if this is not happening, see the last topic "Factory Reset").

Using your phone, connect to "Drop-BOB", wait for your phone to authenticate, it should automatically take you to a web page to begin setting up your connection. Basically, you need to tell your new DropBOB what your wifi network and password is ... its brand new, like a child. It needs to be trained!

Click on "Configure Wifi". Click your Wifi name. Type in your wifi password. Then long click on the "blynk token" field to "paste" the "AUTH TOKEN" you originally copied to your clip board. Click Save.

This basically saves the Wifi and Blynk connections to hard memory, it will remember this even if you leave it powered off for a long time. This is a one time step, unless you factory reset.

Now your DropBOB(tm) should be happily working away at the default settings.DWG. NO. REV.

The front-end Dashboard controls, Blynk

By now you've probably asked yourself ... Where's all the controls? How do I tell this super-smart-almost-artificially-intelligent-device-thing to do my laundry ... We'll here's the fun part. Your "DropBOB(TM)" should now be connected to your wifi and broadcasting its status to a server located somewhere in the world. Blynk also has a great community of builders and hackers. This app lets you customize your "Drop-BOB(TM)" dashboard for you to control anything you want. The limitation is only with the amount of code you want to modify. But not to worry, there has already been enough code written to get you started.

Open you Blynk App, on your new project, click the plus (+) button or swipe the screen from right to left. This will display all the awesome widgets you can add. Go ahead an add anything you like. each of the widget can be configured after you add it to you screen by clicking on them. The Virtual PIN number that each output is attached to is shown below (these functions & variables can also be found inside the code running on your DropBOB, more on that later):

Now go crazy and build yourself a dashboard! You'll be able to control and see your "DropBOB(TM)" status from anywhere in the world that you have internet! This is otherwise know as the IoT (Internet of Things) Revolution. Right now we are only at IoT 1.0 ... Similar to the way the internet had its Internet 2.0 phase, the IoT will also be going through its 2.0 phase as more and more people start using it. So get out there and enjoy your ridiculously delicious cold drip coffee! you coffee snob!
