Because i need fundings i have to sell of my brass blocks to combine 4 diodes. The brass colimators are raisable in height so you can stack two and two on top. I have electronic circuitboards to wire two diodes in series.The boards are mented to put 2 blue diodes that have isolated cans in series but if you remove a small piece of track between the diodes you can use them for red open cans too. You need a Flexmod to run the red opencans parallel with a balast resistor of 1ohm and 0.5 watt. I have good lenses available. I sell the brass blocks seperately without a aluminium baseplate but for those who are interrested in building a 8 setup with PBS or even better with a telescope i have two baseplates with optic table available. Below a list of what i have 4 sale:
5 brass blocks dimension 54mm in lenght 32mm wide
2 basplates to make an 8 setup with optic table.
asking price 160 euro for 1 brass block with electronic circuitboards.
300 euro for an 8 setup and i will throw in the baseplate and some extra circuit boards to swap your open cans to 640nm diodes. Flexmods are sold by DR lava
