Finished first draft of v5.16 assembly instructions
Browse files Browse the repository at this point in the history 
There are still some rough edges in the BOM, and some images of v5.15 -
I hope these aren't critical, but I should update it soonish...

<description>First, assemble the three actuators, as described in the "<a href="#brick_909106319">anti-backlash flexure actuator</a>" brick - it's the same procedure done three times, once for each actuator. You might find the central actuator is the best one to start with. This accounts for most of the time assembling the microscope. NB the instructions for this are later on in this file; if viewing it in Firefox, click "OpenFlexure Microscope" on the left, then pick it from the list of links that appears.</description>
<description>Depending on which version of the microscope body you have, there may be thin supports linking the mount for the optics module to the frame. Snap these off with a craft knife, screwdriver, or elastic band tool.</description>

<description>Assemble the illumination: Bend the LED so it's pointing at right angles to the cable, then thread the wire for the LED through the illumination arm and push the LED into its hole. It's usually easiest to start at the LED end and feed the connector into the mount (it might require a little force). If you have a pre-made LED wire with a connector on the end, threading it through is all that's needed - if you just have the components you will need to connect them together in series first, and solder or crimp them. Some of the pre-made LED wires are thicker than expected, so they take some force to pull into the arm - but they will go in with some perseverance! You can stick a piece of white tape or sticky label over the LED (i.e. between the LED and the stage) to act as a diffuser, this helps to blur out out-of-focus artefacts, such as dirt on the wrong side of your microscope slide.</description>

<name>Illumination Arm with Condenser</name>
<abstract>A holder for an LED and lens to take images in transmitted light.</abstract>
<long_description>The illumination arm holds an LED above the sample, with a condenser lens. It will get higher resolution and brightness. There is a screw holding the two parts together, which goes through a slot to allow simple, slip plate style adjustment of the condenser alignment.</long_description>

<assembly_instruction>
<step>
<description>To build the condenser, you will need the two parts of the mounting arm, an M3 screw and washer, the cable, LED, and lens, and the condenser housing. You will also need the printed lens insertion tool to put the lens into the holder.</description>

<file url="./images/condenser_parts.jpg" />
</media>
</step>
<step>
<description>Place the condenser lens on the insertion tool (flat side down), and push the condenser housing down onto it. Take care to keep it vertical. You may need to push fairly hard. As with the tube lens in the optics module, check it's flat and push again if necessary.</description>

<description>Assemble the cable for the LED. If using pre-crimped cables, as supplied with our kit, fit the 2-way header to either end. Don't worry about polarity, it's easy and harmless to simply rotate the connector 180 degrees if you need to.</description>
