__TOC__

== Summary ==
The kiln only has manual operation right now, where the operator chooses the maximum temperature, time and rate. This works for some materials, but other require more advanced control, so we will make it digital. With a triac, the already present thermocouple (and an accompanying thermocouple amplifier) and an arduino/esp8266

== Important Features ==
* Can reproduce old Controller's functions
** Rate Control (assuming linear)
** Timer
** Maximum Temperature
* Using PID

== Cool Features ==
* Allow for multiple stored "profiles" of temps, rates and times
* Make the controller, and profile creator, accessible online
* Record power consumption
* Design a nice faceplate to replace the controller's current one

== Old Controller ==
Very simple and analog, operates at 240 AC and toggles a LC1D2501 contactor at frequencies above 1/60 of a hertz. Below are the internals, a simple sketch of how it is wired might be added later.

We tested the triac with an arduino, it worked perfectly. We will probably power the arduino with one of the US USB port power supplies.

== 2018/2/23 ==
The controller will have an input of 5 buttons and 3 displays (2 x 4 Digit 7 segment for Actual and Target Temp and 1 x 16x2 LCD to show Kp Ki Kd, time, selected profile etc.) The oven's current theromocouple (k-type) will be attached to a MAX31855 (Range of about -270 to +1800 C, resolution of .25C), which itself will be attached to the arduino. The final component is a 480D10-12 solid state relay.

The code will use the Brett Beauregard PID library (there may be a better choice but I liked reading the explanation of PID on his [http://brettbeauregard.com/blog/category/pid/ website]) as well as the LCD library and the 4D7S code from an old project.

Zaterdag 26 januari is het weer zover, dan viert revspace zijn
verjaardag / hebben we onze traditionele nieuwjaarsborrel met BBQ.

??? regelt de BBQ (inkopen, barbecues, etc.), maar heeft tijdens de
dag zelf wel hulp nodig met de bbq (sla en brood snijden, afwassen, etc.).

= Activiteiten =

* Jouw activiteit hier

= Takenlijst BBQ =

Kun je de verantwoordelijkheid aan? Zet je naam erbij :-)

; Regelen huur extra BBQ's en tafels
* Jij?

; Inchecken gasten

= Aanmeldingen =

Bij "vlees" en "vega(n)" graag het aantal mee-eters vermelden, als je vegaN wilt hebben, zet het erbij, anders krijg je vegA. Kosten voor het eten: €8,- per persoon. We rekenen dit via Revbank met je af.

We gaan tot maximaal 100 aanmeldingen :-) (er is voor 100 mensen plaats in het gebouw, je MOET dus aanmelden om naar Revspace te komen deze dag.)

Zonder wiki-account aanmelden kan ook. Vraag op [[IRC]] in #revspace (freenode) of iemand je wil toevoegen, of e-mail via https://revspace.nl/Contact

== Summary ==
The kiln only has manual operation right now, where the operator chooses the maximum temperature, time and rate. This works for some materials, but other require more advancec control, so we will make it digital. With a triac, the already present thermocouple (and an accompanying thermocouple amplifier)and an arduino/esp8266

== Important Features ==
* Can reproduce old Controller's functions
** Rate Control (assuming linear)
** Timer
** Maximum Temperature
* Allow user to enter multiple target temperatures and rates over a long period of time
* Possibly using PID, if that's a good idea

== Cool Features ==
* Allow for multiple stored "profiles" of temps, rates and times
* Make the controller, and profile creator, accessible online
* Record power consumption
* Design a nice faceplate to replace the controller's current one

== Old Controller ==
Very simple and analog, operates at 240 AC and toggles a LC1D2501 contactor at frequencies above 1/60 of a hertz. Below are the internals, a simple sketch of how it is wired might be added later.

We tested the triac with an arduino, it worked perfectly. We will probably power the arduino with one of the US USB port power supplies.
