− | === OpenPCR in the wild ===
| |
− |
| |
− | Attempt to build an OpenPCR just from the desctription on the website [http://openpcr.org/downloads/ OpenPCR] without a kit or any supplied parts.<br>
| |
− | <br>
| |
− | First and easy thing is to go up to a FabLab and laser cut the wood parts for the housing. Need to get the files from the website and have the most recent version of SolidWorks to extract the drawings...<br>
| |
− | <br>
| |
− | Here we go;<br>

− | [[File:pcr_laserhousing.jpg|none|400px|]]
| |
− | And the one pdf with all the parts as of November 2012:<br>
| |
− | [[File:pcr_laserfiles.pdf|none|400px|]]
| |
− | <br>
| |
− | Got some additional information from Josh from OpenPCR: The downloadable files are the more recent versions of our design.<br>
| |
− | <br>
| |
− | And:<br>
| |

| |
− | The OpenPCR BOM can be found here: <br>

| |
− | Good to know.<br>
| |
− | What else do we need?<br>
| |
− | - The PC-Cooler with 90° heat pipe is easy to get for around 20 euro.<br>
| |
− | - The nice and small power supply that fits into the housing is not so easy. It is a "Flex 1u PC Power Supply 200 W ATX. Bigger (standard size is more easy and should do, just won't fit into the housing<br>
| |
− | - Arduino ok, SMD driver board with AD converter, connectors, feasible. Will try to simplify the layout to make it single-side DIY. What are the big resistors for? Some kind of heating? Have to figure out.<br>
| |
− | - LCD Display - standard, anything goes, 4 Lines are nice.<br>
| |
− | <br>
| |
− | Now one tricky part is the heatblock and the peltier element. For those we have two nice hacks:
| |
− | 1. A peltier element with the exact right dimensions and with some luck even the rough thermo-block can be found in one of those little electric fridges:<br>
| |
− | [[File:pcr_fridges.jpg|none|400px|]]<br>
| |
− | Found those in electronic waste.<br>
| |
− | [[File:pcr_extraction.jpg|none|400px|]]
| |
− | Unscrew the blower and the cooler and you will find the peltier element.
| |
− | [[File:pcr_heat_parts.jpg|none|400px|]]
| |
− | All you need, a aluminium heat-block (thing the original OpenPCR heat-block is cooper and then chromed, right?), peltier element...<br>
