What is the Yet Another Cooking?

Yet Another Cooking

-API Based -Via your gadget

-Reproducible -And Automatic!

API Based

We dont have to manipulate with old-fashioned controllers (knobs, switches and etc)

API Based

Cooking API is provided means we can cooking with our favorite gadgets!

Reproducible

No matter who cooks, the same dish will be ready

AutomaticThe life is short to cook elaborate meal. We should make cooking to be automatic!

Yet Another Cooking = Programmable Cooking

AutomaticThe life is short to cook elaborate meal. We should make cooking to be automatic!

Nomiku has come

What is Nomiku-Low temperature cooking device

-Keeps temperature of water

-And provides API!

What is the low temperature Cooking?

Low temperature cooking

-Also called Sous-vide" -Putting a food into water tank which is controlled temperature constant

- Myosin (denatured @ 40) - Actin (denatured @ 66)

For meat

For meat- Meatto be parched ifactin gets denatured

- But we must killbacteria - Must keep 60-65 - (And collagen will hydrolyzes at about 65 degreed)

For Vegetable- Root vegetablesindurate on 60

- Avoid tofall apart while boilingbyparboiling

It is difficult to keep water temperature constantly than I thought


If mistake to keep temperature,it is DANGER cause by bacteria!!!!!

Nomiku solves them!!!

Great! But

Nomiku ga konee!!!

Its no good worrying. Okay, lets construct

Nomiku compatible device *** by hand ***

Features list

- Keeping temperature of water long time

- Controlable via web API

Features list

- Keeping temperature of water long time

- Controlable via web API

Simple!

API Spec- Start heating - And stop - Change temperature - Get status

How to keep temperature?

- A daemon monitorstemperature of waterand store it into GrowthForecast

How to keep temperature?- A server gets current temperature from GrowthForecast - If it is greater than target temperature, turn off relay

- Less, turn on relay

Good and easy!

Yet Another Cooking;

API Based Reproducible Automatic

API Based

Provides web API on Raspberry Pi. It makes us able to cook with favorite thing! (My favorite is cURL)

Reproducible

We only just share a source code which uses web API and run it.

Reproducible

Automatic

It keeps temperature without our control.

Application Example

Use with slow cookerUsing slow cooker instead heater is nice idea. You can cook almost the same. Ref: - Cooking for Geeks - http://blog.naotaco.com/archives/

Other electronic devices

- Hot Plate - It looks difficult to

control - Convection Oven

- Looks good

Can we automate frying?

Can we automate frying?

DANGER!!!!!

Future works

- Cooperate with - CI mechanism - crontab

Future works

- Safety improvements

Future works

-

DANGER!!!!!

Future works

- Generate convection

Conclusion

Conclusion

Now gadgetis a new cooking toolwith using web API

Conclusion

Sharing source code = Sharing recipe

Conclusion

It is able to automate of cookingby power of device

Conclusion

Nowadays such devices are on the market! (e.g. nomiku, anova)

Conclusion

And we can make device by hands with a bit DIY splits!!

Conclusion

It is fun!!!

Yum!!!!!
