Opensource hardware with Arduino, why PID is hard
- 1. OPEN SOURCE HARDWARE Open source electronics prototyping platform with ARDUINO
- 4. ARDUINO NETDUINO 16 MHz 8-bit AT mega 32K 2K ~ 25 EUR,- Native (Cpp) 48 MHz 32-bit Atmel ARM 128K 60K ~ 50 EUR,- Micro SD Ethernet .NET TinyCLR CPU Max program size RAM
- 5. HMM, BEER!
- 6. HMM, BEER!
- 7. BREW PROCESS Mashing -> Boiling -> Cooling -> Fermenting -> Bottling
- 8. MAISCHEN Heat water to 64 C 40 min. at 62 C 20 min. at 72 C 5 min. at 74 C Temperature control
- 9. THE CALCULATIONS 4186 joules for 1 Liter water to heat 1° Kelvin 1 Watt = 1 joule / second Heater = +/- 1000W Heat 20L water 25° = 4186 * 20 * 25 = 2093000 joules 2093000 / 1000 / 60 = 34 min.
- 10. AUTOMATIC HEATING The materials • Electric heating plate • Npn temperature sensor • Arduino • Relay • LCD touchscreen
- 11. ARCHITECTURE
- 12. PID proportional-integral-derivative controller (PID controller)
- 13. NO PID Heat only; Only On-Off switch; Measure Delta • Far – long bursts • Medium – medium bursts • Close – short bursts
- 14. EVENT LOOP
- 15. SOFTTIMER WHEN YOU GET MORE NEED FOR CONTROL
- 16. SOFTTIMER WHEN YOU GET MORE NEED FOR CONTROL
- 17. GUI
- 18. GUI
- 19. GUI
- 20. SHOW ME THE CODE AND HARDWARE !
- 21. BUILDING STUFF IS EASY! OPEN SOURCE HARDWARE IS ALL AROUND CHEAP AND ACCESSIBLE CONNECTIVITY IS EASY
- 22. WHAT WILL YOU DO? You can build almost anything you can imagine yourself
Editor's Notes
- Last year I saw an inspirational ted talk about open-source ecology… Open source hardware is everywhere. You see it in electronics, but also in music and agriculture. This image is the LifeTrac 2 open source Tractor, you can find this on opensourceecology.org. An organization dedicated to open source hardware and villages, so you can build your own farm and your own equipment. With the coming of new technology, such as the 3d printer, online communities and the open source dogma, you as an individual are empowered to create anything.
- Why people use this? You can build it yourself Cheaper than commercial manufacturing You can improve designs, and contribute to the community
- Cool. I want to build something and play with these toys. I always wanted to do something with electronics, so I bought an arduino and a netduino. Both are open source hardware, created for prototyping electronics. So what is this stuff: Microcontrollers, with Digital and analog IO…

- Last year me and some friends started brewing beer (and some mead). When this is fermenting a constant temperature is desired…
- I’ve got the stuff, played with it a bit. What to do, what to do, so many options..
- Let’s start easy, I got a temperature sensor in the starter kit. So how hard can it be to show the temperature…. (and later maybe other data, or maybe i can control some heater or cooler based on the current temperature)
