| ==Status==
| | Is used guide is on line some where |
|
| |
|
| <s>Currently broken, due to damage sustained moving it. Not serious - requires a new mains lead.</s>
| | Put in Physics sub cat as was not sure where else to put it |
| 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.
