So the NEST Hello has just been released in the UK starting delivery 11th June 2018, which is great but we are currently not getting a full picture on installing the Hello and its ancillary equipment requirements.
Now it might prove that Google (Nest) supply the extra bits that we need (but I doubt it - going off other countries experience)

So what do we need:

  • Nest Hello (Obviously)
  • Suitable bell wire
  • Door chime 
  • Bell transformer
  • Din Rail Enclosure
  • Ancillary bits depending on how you install.

So whats the problem ? All standard kit I hear you say.

According to Nest Hello website the doorbell needs:

  • Power requirements - Requires a 16 V AC – 24 V AC, 8 VA transformer, chime and a wired doorbell.
  1. The Problem being is we can source 24v Bell transformer (British General) but cannot get a 24v door chime.
  2. Or we can source a 16v door chime (Friedland / Honeywell) but we have been struggling to find a 16v Transformer. Also to note here is that I spoke to Honeywell about the VE117 door bell and they tell me it's being discontinued so order one quick if thats what you want. 

As I could not find a 24v chime I went looking for a 16v Din Rail mounted transformer which I found made by Protek.


So here’s the items and also the Door chime spec sheet at the end:

  • Door Chime = Friedland VE117
  • Transformer = Protek BT8-16 or BT10-16
  • Din Rail Enclosure = 3+ Spaces 
  • Bell wire = make sure spec is high enough
  • Nest Hello = at the time of this article no ones sure what we will get in the box, apart from the Hello itself.

How to access system Bios on a Toshiba Satellite Pro C660. Are you struggling to gain access to your Toshiba laptop Bios ? Your laptop probably has fast boot enabled and is simply skipping the initial splash screen that advises how to access the Bio. Any sign off how to access the Bios when you push the start button are not shown when starting up. The way to access the bios is quite simple but has to be followed EXACTLY or you will simple boot to the os. Make sure machine has been shut down completly. Hold F2 key down. Push start / power button whilst still holding F2. IMPORTANT - When the Toshiba logo is shown you must release the F2 key if the Toshiba logo disappears before you release F2 the machine will simple boot into the Operating system.  Now you have access to the BIOS. Once you have disabled fast boot when you restart your laptop the initial screen should look like this clearly showing options for accessing the Bios F2 (SETUP) or F12 for Boot Menu.
