 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Nope, unfortunately I haven't got one of those displays (and I can't afford one at the moment). The general form of construction is similar to the original Hydra so those instructions are a good guide. The main differences are that the display is wired differently (obviously!), the PCB over the Armmite is narrower to make it easier to read the pin text and there are a few more components squeezed in. There is one point - on the revised board there is an optional Piezo sounder. This has to be an *active* type and could also be a 5V active magnetic type. Passive devices won't work. I'll try to get round to some circuit diagrams, but they would be so rudimentary really. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

It's a sweet display. I have several working on the F4 using a minimalist adapter. I expect JLC to say they're shipping it any day now. Then about 10 days for delivery. PicoMite, Armmite F4, SensorKits on fruitoftheshed |

They usually take 2-4 days to manufacture. 2 days in green, 4 in a colour to match your curtains.. :) I don't know if these will be a little slower, being 4 layers and a funny shape.

This is the combined circuit diagram for the various versions of the Hydra. Hydra II is still work in progress. I'm considering going back to 2-layer boards as I've discovered that it's possible to do, if a little messy.
