Robert Brown Arduino dew controller build, step by step #9

For the final bit of PCB soldering, the MOSFETs and voltage regulator. The heatsinks I bought turned out to have small steel “legs” on when they arrived, which I didn’t initially realise was the case. I assume they’re there so … Continue reading

Robert Brown Arduino dew controller build, step by step #8

Fly leads for the diodes attached. No diodes as yet. I’ll cut the leads to length and fit the diodes once I’ve printed the case and can test everything for size/placement.

Robert Brown Arduino dew controller build, step by step #7

All the pin headers that I’m going to use are now in and there aren’t too many holes left, especially as the two four-pin headers that are left won’t be used (the ones for the Bluetooth connection and the HTU21D … Continue reading

Robert Brown Arduino dew controller build, step by step #6

I have now soldered all the resistors and capacitors to the PCB: Yes, I have put all the resistors the same way around. I can’t help myself 🙂 My favoured method for dealing with the resistors is to put a … Continue reading

Robert Brown Arduino dew controller build, step by step #5

Time to start some actual construction! Whilst the PCB was uncluttered I decided the first job would be to solder on the headers for the Arduino, so I used the junior hacksaw to cut a couple of 15-pin lengths from … Continue reading

Robert Brown Arduino dew controller build, step by step #4

Right then… Components… I’ve given links to the places I purchased parts from where they still exist or if I still have them, but a few things I already had. I have no connection with any of the vendors and … Continue reading

Robert Brown Arduino dew controller build, step by step #3

I’m going to post details of the components I used, but before that some comments on the circuit board… The documentation provides a plan for building the controller on stripboard, which looks perfectly good (but you’ll need to add a … Continue reading

Robert Brown Arduino dew controller build, step by step #2

Since it’s relatively easy, I’ll start with the tools required. I think this is pretty much everything I needed for the first build. Covering the easy stuff first, obviously there’s the soldering iron. It would be nice to have a … Continue reading

Robert Brown Arduino dew controller build, step by step #1

In an earlier post I said I’d write up the build of my second dew controller, so if you’re not sure it’s for you and need to see how someone else did it, this is it. There are a few … Continue reading

DIY dew controller

As we get later into Autumn it is becoming obvious that dew control is going to become necessary for my telescopes. To do that for all my OTAs would be quite expensive, so I looked around and found Robert Brown’s … Continue reading
