Let me admit it – I’m quite deaf! Despite having a digital hearing-aid in each ear, I still miss hearing the doorbell when I’m working in my den. All to often I find that a parcel delivery has been attempted – the result of my not hearing the doorbell is usually a card inviting me to pick up the parcel at the post-restante not less than 48 hours from the failed delivery attempt. Then there’s the problem of hawkers and cold-callers – on the occasions when I do hear the doorbell, it’s inevitably someone who simply wants to waste my time trying to sell me new windows, a new drive, new roof or whatever. These people get a curt ‘No thank you’. Those that persist get something much stronger – which I won’t repeat here.
When I do have to go out, and I’m half-expecting a parcel delivery, I have to stick a hastily-written note on the inside of the window beside the front door. I thought I’d have a go at addressing these issues with a messaging system connecting up the various items and linked in to my PC in the den. It had to be cheap, reliable and easy to modify, so a home-brew solution was sought. I’ve ruled out wireless-connected TCP/IP because to date my experience with wireless networking has been a complete waste of time – with transmission dropping out just when it’s needed. The next choice was a USB-based connection, and so a trial was done with a 20 metre length of high quality cable connecting the PC to a lashed-up USB slave unit based on Microchips 18f4550 PIC. No problems were apparent transmitting short messages and commands. A £5.00 USB camera from Tesco again connected to the PC by high quality cable completes the surveillance part of the system.
