Get a glass tumbler, put it in a small saucepan filled with water, heat the water up to the required temperature (78C)
Get a funnel, put it over the mug with a length of tube so the evaporate goes up it. Run that tube into a bottle in a bowl full of ice. In theory that should be enough, the hot gasses with travel around the tube into the bottle and condense. If you can loop the tube up high, then come down, you'll get some condensation due to the air temp cooling the gasses before they get to the bottle. You'll need to make a small gap in the top of the bottle (the bigger you can make it the better to account for this) to allow some of the hotter gasses to escape, or it might explode under pressure.
Its not too efficient, but you'll get your alcohol if you keep the temeprature right on the stove. You will get water in there, thats unavoidable, but it will be mostly ethanol.
I've just realised the schematic i put up is of a reflux unit, not a condenser, so i will find a better one for you.
Edit: Fixed with a diagram of the lab apparatus i use.
