==Status== | |||
<s>Currently broken, due to damage sustained moving it. Not serious - requires a new mains lead.</s> | |||
Now fixed and situated between welding and pcb manufacture (not ideal!). | |||
The chamber is currently 'on trial' as hackspace equipment : it takes up a moderate amount of space and may not prove to be useful. If this is the case, I will move it on, perhaps to another user. So please don't leave it in pieces or make permanent changes without talking to me first. --[[User:Artag|Artag]] 16:14, 30 March 2011 (UTC) | |||
There is an old square baking tray kicking around that could be used for anything that might melt, drip or otherwise mess up the inside of the chamber. I left it inside the chamber but it could end up anywhere in the space. As of november 2011 I havn't seen it for a while. | |||
==Uses== | |||
I've mainly brought this in for possible use in biohacking - it will cool, heat, hold a temperature, follow a simple profile and might be hacked to allow further control. However, there are other possibilities : | |||
* Beer cooler (has been used for this) | |||
* Pie warmer (and listeria farm .. see biohacking) | |||
* Sous vide roaster (and listeria farm .. see biohacking) | |||
* Vacuum forming oven (this is what I originally intended it for) | |||
* Glue drying / thermosetting (the most recent commercial use) | |||
* Electronics testing / fault diagnosis (common industrial use) | |||
* Low-temperature firing for polymer clay or similar | |||
* Heated build cabinet for cupcake | |||
Temperature range is <unknown, maybe -10> to +200 C | |||
==Controls== | |||
[[File:Chamber_control_panel.jpg]] | |||
I'm going to have to try it again to give proper details and never really got a good idea of the temperature controller, but the important parts are : | |||
* Switches at top - mains, internal lamp, fridge unit | |||
* Temperature controller - set temperature demand and show temperature. | |||
* Temperature dial - does NOT set temperature, It sets the over-temperature trip level at which it will automatically cut out. Set it just above the maximum you will require. | |||
* D-type connector- Don't know. Possibly RS232 to controller. | |||
Heating operation is straightforward. Just set a temperature higher than ambient and don't switch the fridge on. | |||
Cooling operation is less obvious - I think the cooler itself runs to a very coarse setting and the heater is used for fine control. In particular, I think you have to set an auxiliary control output on the temperature controller to enable the cooler. I have had this working so it's not impossible but may require a bit of fiddling. | |||
I had a go at using the environmental chamber to make sure some welding rods were free of moisture. | |||
The user interface is still a mystery to me but I pressed buttons until the top red numbers showed current temperature, the lower red numbers showed "100.0" (desired temperature) and the XK1 and "hand" red LEDS were illuminated. I left the green switch with a snowflake symbol off. | |||
The temperature shot up to 50degC quite rapidly then took a couple of minutes to get to 100degC. The XK1 led flashed when it was at 99.9degC. --AJP | |||
==Rough Instructions== | |||
<B> Simple temperature-setting instruction: | |||
Press and hold (3s ish) 'hand' button until the display shows 'SETP'. | |||
Set required temperature using up and down arrow buttons. | |||
Press and hold (1s) 'enter' button, twice. --PaddyD </B> | |||
Below is a manual for the controller in the oven. Please note that it is generic: it does not refer to this particular implementation... :) | |||
[[Media:b70.6040gb_DICON_PRS_09.90.pdf]] --PaddyD | |||
All buttons need to be pressed and held for some time: | |||
Press the program (PGM) button. Alter the program with the up arrows (it over flows) and press enter to change the part of the program your are altering. | |||
Press the circular bidirectional arrow and dot button. This starts a program (sometimes....). Select the delay before the start of the program and some other options. Press enter to cycle through these options. | |||
==Careful== | |||
* Don't leave it on unnecessarily, wasting electricity | |||
* If you have to move it, try not to drag it. The feet will fall off. Check when you've finished that they're all still fitted. | |||
* Don't lose the trays that are inside, especially the fitted one it came with. | |||
