We ran tests at the Suicide Bunker recently, to make sure that the drink-making portion of El Espanol Borracho functions adequately for Roboexotica.
We gathered a Scientific Crew of Impartial Observers™, and laid in a stock of cupcakes and we were set to go.
The recipe for the Suicide Spanish Coffee is as follows:
1 part very fine Coffee Liqueur
(We find the specific gravity of Kahlua 14% higher than water) lends itself best to what follows)
A Gentle Splash of 151 proof rum
(the one that says “WARNING! DO NOT EXPOSE TO HEAT OR FLAME works very nicely)
Whipped Cream
Have the robot measure out the Kahlua into the waiting vessel, and then have it add a touch of rum.
Hit “Go” on the flamethrower.
Offer flaming beverage to associates with wishes for their good health and joy of the season.
After two or three offerings, consume cream directly from bowl.
Giggle over arcane speed controller jokes.

At the end of the evening, The Suicide Special was mixed, re-mixed, lit, extinguished, creamed and was pronounced by all partaking parties as “Fit”.

Here’s the obligatory educational part (because what fun is science if you can’t duplicate it?):
ESB is run on a BASIC stamp, a microcontroller that has a tons of documentation and support available. This makes it great for beginners and advanced tinkerers alike.
The BASIC stamp is connected to the pumps dispensing the alcohol and the flamethrower. One switch on the remote controls the entire drink-making process. If we get fancy we’ll also have a “go” button or something on the machine itself so anyone can ask for a drink directly from the robot.
At the moment, the alcohol pumps are taken from a medication dispenser scrounged from a flea market. All the tubing is food safe the the pumps can be sterilized with hot water or (gee) alcohol.
The flamethrower is a cute little number that was liberated from a robot made for a previous show. It consists of a small fuel tank filled with isobutane/propane camping fuel, plastic tubing, a transformer (yours does not need to be this big, we just like compensating), a double-A battery pack, a spark plug, and a guide around the nozzle made from the remains of another fuel tank. It’s mounted on a small sheet of bent copper. The whole shebang is held together with zip ties and love. It was originally made by flame gangsta Charlie Gadeken and Mr. Robotics.
If enough people ask we may be able to get them to do a HOWTO on very small flamethrowers.
We might replace the pumps I am using right now with small solenoid valves, assuming we can get them in time and that they costs less than one’s average firstborn. Solenoid valves would look more elegant and would probably fit the frame better.
The whole thing rides on a clear lexan-paneled hockey bot, about which more in a later post, with pictures!
If we feel especially fancy, we might add bumpers and sonar to ESB, increasing the chances that someday he’ll be a real boy and be able to navigate (and set people’s toes on fire) autonomously.
The operator controls the robot with a GWS RC controller, used for all kinds of RC cars, planes, etc etc.
The rest of the evening is sumptuously chonicled here in Violet Blue’s Robothaus Flickr Set or a short video.
The scientific findings of the field trials concluded that more than two Suicide Specials consumed in one evening can lead to dizziness, shaking, improper use of roman candles, and cupcake abuse:
