  1. Astrobaby?

    I think the light pollution and living in a flat where she had to lug her gear up a load of stairs finally got to her.
  2. James Webb

    I kept thinking that someone was going to jump out and shout "April Fool!"

    I have given up on this project ever being completed in my lifetime. Northrup Grumman should be replaced by a competent company.
  4. Live rocket launch

    And Arthur C Clarke. They used "It's full of cars" somewhere along the line.
  5. 35mm Film for AP?

    I have an old Olympus OM1 going spare
  6. They used to make an f6.6 version, I have one but it is branded Opticstar; this was before Bresser got involved. It got a much better review that the shorter version. Also there are a lot of plastic parts. Opticstar 102 F6.6 scope
  7. Windows update warning

    Eben Upton spent a lot of time on the Raspberry Pi blog explaining why the Raspberry Pi is not affected Why Raspberry Pi isn't affected
  8. Top five astro event wish list for 2018

    I remember this geomagnetic storm. An ex friend called me the next day to tell me about it A missed opportunity
  9. BBC Microbit

    All this talk of lightning, I've just been woken up by intense flashings and booms of a storm.
  10. Heads up; Future Learn Orion free course

    Doing the practical work can be very frustrating because of the weather
  11. Any Ardunio + Windows programmers out there?

    I use a Raspberry Pi, a small 433Mhz rf transmitter and a set of rf controlled mains plugs. The software is free on github. I use the default app crontab to set up the timers. 433Mhz RF TX/RX Modules Remote Controlled Sockets I have my sockets controlled by a Raspberry Pi and an Amazon Echo via an esp8266 board. They work my lounge lights, bedroom lights and currently my xmas lights The Pi controls the lounge lights for when I get in late in the evening so I don't have to enter a dark house. The Ebay listings are just examples, I bought my devices years ago so couldn't give links to vendors I used.

    Alan, The other technique is to set the camera shutter to stay open for, say 30 seconds, and hope you catch some flashes/multiple flashes. that would be easier with the Microbit if your camera can do B shutter speed Martyn

    Alan, The average duration of a lightning bolt is 0.2 seconds made up of several flashes of about 30 micro seconds each (according to wikipedia). I think you might be struggling to get things fast enough with the BBC Microbit. I know it's a big step into the dark, but have you thought of trying with an Arduino Nano 3.0? They are very cheap and have all the ports you could want. Here's a similar project using the Arduino: http://www.glacialwanderer.com/hobbyrobotics/?p=16 you could use as a stepping stone. Martyn.
