[STEPS]
?. Obtain the list of parts and tools required to build and assemble the illuminated orbital shaker by downloading the file:​OrbitalShaker_PartsList.xlsx​The content of the above spreadsheet are discussed in the steps below.
?. It should be possible to convert any orbital shaker by adding the illuminator and a raised clear acrylic platform to hold the algal cultures. Many labs may have spare orbital shakers that can be repurposed in this way. Second-hand ones could be found on online auction sites and spare lab equipment resellers pages. New professional orbital shakers start at around £700 (2019).It is essential the orbital shaker platform is larger than than 22 cm × 20 cm. Otherwise, the heatsink, fans and stand-offs holding the acrylic platform might not fit.For this project, we bought a basic orbital shaker imported from China. It can be found on ebay. It retailed for £95.30 in May 2019 - including shipment, import duties and VAT. The protocol will always refer to this particular orbital shaker, which is still on sale on ebay (Nov 2019). The shaker worked continuously during the past 6 month without any glitches. The major drawback of this orbital shaker is the loud noise it produces, compared to high-end orbital shakers, which are barely audible.​Below is a table listing the orbital shaker. It is the only laboratory equipment required for this project. The orbital shaker is also listed in the "Laboratory Parts" tab of the OrbitalShaker_PartsList.xlsx spreadsheet.

?. Electronic parts for the illuminated orbital shaker can be sourced from various suppliers worldwide. Farnell was chosen for its comprehensive offer, competitive price and fast delivery. Any other suitable supplier could be used instead. Many of the standard components can be substituted for different parts. This includes the 0603-size resistors, the BSS138W transistor, and the pin header, shunt jumper, and the fuse. The capacitors can also be swapped for equivalent kind, bearing in mind that the rated Voltage and dielectrics must not be lower specification than theose listed.

?. The LED illuminator consists of LED strips attached to a heatsink, cooling fans and wires that connect all components together and the LED controller electronics circuit. The list also includes a wall socket plug-in power supply and a 24-hour time switch to control the daily sequence of the LED illuminator.

155.19Note for Non-UK RegionsThe power supply and the 24-hour timer (items 3 & 9) are for UK sockets. Other parts of the world have different line Voltage and sockets. Find a 30V/1A power supply with a 2.1mm DC connector and a programmable 24-hour socket timer that are suitable and certified for use in your region.Note for Non-Metric RegionsItems 6 & 7 are cables with 0.5 mm2 cross-section. This is roughly equivalent to AWG 21 cables. Choose a suitable cable, which is close to this gauge. Thicker cables can force the LED strips to lift off from the heatsink and thinner gauges may be insufficient to support the current.Note on the Clear Acrylic SheetHere, an off-the-shelf clear acrylic was used. The 4 mm (5/32") thick clear acrylic is ideal. A thinner one might be to weak and a thicker one might be impossible to fix to the stand-offs. However the exact make and size of the sheet are irrelevant. Polycarbonate could also be used instead of acrylic. It may be easier to drill and cheaper, but absorb more light.

435.84Note for Imperial Thread Size UsersReplace the 4 mm drill bit (item 18) with a #16 or #18 drill bit.Use a #4-40 UNC thread tap instead of the M3 thread tap (item 1).Note Regarding Multipurpose GlueThe listed multi-purpose glue worked well. This particular brand may not be widely available outside of the UK. Choose any trasparent solvent-based multi-purpose glue. It is important it is a glue that retains some flexibility and cures through evaporation of the solvent. Do not use PVA or superglue.Note Regarding 3D PrintingItem 17 is a 3D printer to produce the case for the LED controller electronics. We used a locally available FDM printer. However, other 3D printers should work equally well. Both locally available 3D printers or commercially outsourced 3D printing service can be used. 3D printing by laser sintering would offer a better finish, but this 3D printing technology is less widely available and not required.Note Cutting and Drilling ToolsHere, mechanical tools (items 18-21) have been used to cut and drill the clear acrylic sheet to build the illuminated shaker platform. However, with laser cutters widely available these days, a better and quicker job could be done by using a laser cutter instead. In that case, the drill, drill bit, hacksaw, and sandpaper will not be required.

?. The printed circuit board (PCB) has been designed specifically for the LED controller circuit. It is a double sided PCB with plated through-holes. All components are mounted to the top side only for ease of assembly. The assembly of the components on the board is described in the document  Assembling LED Controller Electronics. The top and bottom view of the PCB are in the picture below:The PCB design has been done in KiCAD, which is a cross platform and open source electronics design automation suite. The source files are available for download from the project GitHub page.Any PCB manufacturer should be able to produce the PCB from the Gerber files available in the board folder on the project GitHub page. We used Seeed Technology Fusion PCB service to produce the PCB. The ordering process is described below.Get the archive LEDregulator.zip with Gerber files from the project GitHub pageGo to the Fusion PCB order pageUpload the LEDregulator.zip file using the Add Gerber Files button:  Select the options for the board manufacture. All settings can be left at their default values. Decreasing the order amount to five PCBs does not lower the final price, but could minimize waste and environmental impact.Confirm the order, provide shipping and billing details, choose the preferred shipping service and pay the manufacturer.Wait a few weeks for the PCBs to arrive.Go to the Fusion PCB order pageUpload the LEDregulator.zip file using the Add Gerber Files button:Select the options for the board manufacture.
