A little while back I wrote up a post about Stian Eikeland’s “SousVide-O-Mator”. In the time since, Stian wrote up a great post on his own blog explaining how his project works and how you can build your own control hardware. He writes:
A professional sous vide setup costs at least >$1000, so it’s a bit out of reach for the normal home cook – except for the DIYers.. It’s not that hard to build yourself if you put your mind to it. What you need is the following components:
- Water bath with a electric heater.
- Some method of circulating the water.
- A way of accurately regulate the heater based on water temperature
- Some way of plastic bag packing you meat.
Water bath with heater is easy enough, there are tons of items out there that does this – slow cookers and rice cookers for example. I use a simple rice cooker, the cheaper/simpler the better (we’re going to cycle it’s power on/off, a dumb cooker will behave better facing a power loss). To circulate the water I use a simple ebay aquarium pump (payed $9.90 for mine). To pack the meat in airtight bags you can either buy a cheap vacuum-packer or simply use zip-lock bags (fill your sink with water, add meat to bag, submerge bag in water but keep the opening above waterlevel – pressure from the water will press out all the air, seal the bag..)
You can check out his whole write-up here. Great job, Stian!
