Barobot Serves Cocktails While Using Open Design the Right Way

barobot-mechanical-bartender

Oh for the day when we can stop repeatedly looking up our favorite drink recipes on Wikipedia. Those may be just around the corner and you’ll have your choice of single-click delivery or toiling away in the workshop for a scratch build. That’s because Barobot is satisfying both the consumer market and our thirst for open hardware goodness. They’re running a Kickstarter but to our delight, the software and mechanical design files are already posted. Before you dig into the design files there’s a really good look at the constituent parts in the assembly manual (PDF) — that’s a lot of pieces! — and a tiny bit on the tech-stuff page.

This remind us of the Drinkmo we saw earlier in the year. That one cames complete with the high-pitched whine of stepper motors. We didn’t get to hear Barobot’s ambient noise in the promo vid after the break. But one place this desing really shines is a swiveling caddy that allows for a double-row of bottles in a similar footprint. One thing we’d be interesting in finding out is the cleaning procedure. If anyone know what goes into cleaning something like this let us know in the comments.

An Open Source Cortex-M0 Halogen Reflow Oven Controller With LCD

reflow oven controller

Homemade reflow ovens are a great inexpensive way to quickly solder multiple prototypes at once. [Andy] may just have built one of the best ones we’ve featured so far on Hackaday. For his project a £25 1300W 12litre halogen oven was chosen because of its low cost and fast heating time, the latter being required to follow typical reflow profile ramp-up stages.

To control the AC power [Andy] first bought a chinese Fotek Solid State Relay (SSR) on ebay, which was quickly replaced by an american one after reading concerning reports on the internet. He then made the same ‘mistake’ by buying the typical MAX6675 thermocouple-to-digital converter from the same website, as he spent much time understanding why the measurements were wrong when the IC was just defective. His final build is based around a 640×360 TFT LCD that he previously reverse engineered, the cortex-M0 STM32F051C8T7, a SPI flash, some power regulators and buttons. The firmware was written in C++ and we’ll let our readers visit [Andy]’s page to see how well  his oven performs.

Barduino, Now With Facebook Integration

Bar

We’ve seen BarBots that will automagically pour you a drink, but how about one with RFID? How about one with Facebook integration, so your friends know how much of a lush you are? Wait. Facebook already tells them that. Huh.

[Andy] and [Daniel]’s latest build follows on the heels of a lot of similar cocktail bots; an Arduino controls a few solenoid valves connected to a CO2 supply and a few bottles of liquor and mixers that allow drinks to be dispensed at the push of the button. Where this project gets interesting is its use of RFID and Facebook.

The user interface was coded for Windows 7, with an RFID tag (ostensibly issued to each guest) allowing a unique login that checks an SQL server to see what privileges the user has. The app pulls the user’s Facebook profile photo down and displays it in the corner of the screen, and with the server keeping track of how many drinks (and of what kind) they had, with the right permissions it should be possible to post that info to their wall. Because we all know what you did last night, even if you don’t.

Bacon Alarm Clock Won’t Burn Your House Down

Bacon Alarm Clock

If you have trouble waking up in the morning then maybe this alarm clock is for you. A bacon-aroma-releasing alarm clock!

Fueled by her love of bacon, Instructable’s user [llopez2005] decided she wanted to try making an alarm clock that would actually get her out of bed, hungry, and ready for bacon. Instead of trying to design a clock that would actually cook bacon — which might be a bit dangerous — she’s found an extract of bacon aroma which she could slowly release instead.

The clock makes use of an Arduino Uno with a RTC shield as well as a LED array for the clock’s display. The “bacon” is actually made out of bake-able clay, which sits on top of unscented wax, infused with the bacon aroma oil. The bacon and “bacon grease” sit in a baby frying pan over top of a small heater element designed for warming candles. Before the alarm goes off, a SSR turns on the element which slowly melts some of the wax, releasing its ever so delicious scent.

What we really like about the clock is the level of detail she put into its appearance. The base is designed after a small wood burning stove they have in the house, and she’s even made a Plexiglas display case for the frying pan — with holes to let the aroma out though of course!

The Egg-Bot Gets A Little Wax Stabby

eggbot

With Easter just around the corner, [Windell and Lenore] over at Evil Mad Scientist Laboratories have come out with a new upgrade for their Egg-Bot. It’s called the Electro-Kistka and it allows your Egg-Bot to do wax-resist egg dying — in the same style as Ukranian Pysanky.

This isn’t the first time someone’s strapped a kistka to an Egg-Bot, but after seeing how much fun their customers were having, [Windell and Lenore] decided to make their own. It consists of two main components, a heater assembly that attaches to the Egg-Bot’s arm, and a power control board. To apply the wax they are using a kistka tip (looks like a soldering iron tip with a hole through it) which feeds molten wax onto the egg through capillary action.

It works almost exactly the same as the regular Egg-Bot arm, but allows you to dye your eggs with a very stark contrast as the wax repels dye perfectly. Just take a look at the following intricate designs.

Smart Microwave Shows You How It’s Done

Do you still have technical difficulties with your microwave? Never know how long to put that half eaten hot-pocket in for? With the nextWAVE (trademark pending) you don’t need to know! Simply scan the bar code and let the nextWave do its thing — wirelessly!

[Kashev Dalmia], [Dario Aranguiz], [Brady Salz] and [Ahmed Suhyl] just competed in the HackIllinois Hackathon 2014, and their project was this awesome smart microwave. It uses a Spark Core Microcontroller to control the microwave and communicate wirelessly over Wi-Fi. They’ve developed an Android app to allow you to scan bar codes, which are then looked up in a Firebase Database to determine the optimum (crowd sourced) cook time. To make it easy for anyone to use, an app link NFC tag is placed on the microwave for easy installation.

It even automatically opens the door when it’s done — and plays Funky Town! Oh and it also has a Pebble app to show you the time remaining on your food. We think this Raspberry Pi microwave might give it a run for its money though…

Happiness Is Just A Flaming Oxy-Fuel Torch Away

The Egg-Bot is pretty awesome, we must say. But if you have one, you end up with lot of delicate, round things rolling around your abode and getting underfoot. Warmer weather is just around the corner, so segue from spring gaiety to hot fun in the summertime with the MarshMallowMatic kit from [Evil Mad Scientist].

The MarshMallowMatic is a CNC oxy-fuel precision marshmallow toaster based on the Ostrich Egg-Bot design. Constructed from flame-retardant plywood, it is sure to add an element of delicious danger to children’s birthday parties and weekend wingdings alike. You don’t have to get too specific with those BYOM invitations because this bad boy will torch standard and jumbo marshmallows like a boss.

The kit includes a 5000°F oxy-fuel torch and a 20 ft³ oxygen tank, but the tank comes empty and you’ll have to supply your own propane, acetylene,  or hydrogen. It comes with adapters to fit disposable propane and MAPP cylinders, which are also not included. However, you will receive a fine selection of sample marshmallows to get you started. Watch the MarshMallowMatic fire up some happiness after the break. You could toast a special message and load it into this face-tracking confectionery cannon to show how much you care.
