Thanks Vinit.
Glad you enjoyed the site.
Thanks.
Could you please forward me one of those emails. I am sure someone is simply using the domain name in the return email address since it's just spam... By looking at the originating mail server I can ensure that it didn't come from our servers.
Hi Colin,
As designed the outputs only allow enough current to power up to 2 LEDs. This limitation is not due to the transistor limit but the biasing of the transistor to prevent output short circuit damage. A small circuit change would allow for additional lights to be driven, but it would also remove the short circuit protection. We are only mail order but we may be able to work something out. A new project is in the works.
Regards,
Alan
You should be fine. Just double check the input rating of the devices and make sure they can accept that voltage range (should be in the manual). One thing you could do is setup a simple zener diode circuit to prevent over voltage if you thought it may be a problem.

Thanks.
Hi Jim,
The link seems to work now.

That seems to be a common problem with some of the newer Hard Drives, they have much more fault detection circuitry. You may not be able to get around that.
Hi Riaan,
There are 10 separate outputs and each one can power 2 LEDs. So the simple answer is no, it can't power 40 stair lights with no modifications. Sorry, I'm not sure how easy it is to get these parts in South Africa. What many people that have many stair levels do is install two kits, one for each individual stairwell.
The buzzer output comes on with the lights, you could change that in code but that is the default operation.

Hi Len,
To work with a 7200 RPM drive you will have to adjust some of the variables in the code to allow the hands to display faster and smaller.
Hi Ram,
Thanks for the kind words!
Hi Colin,
That is very possible. If the speed is different you will have to adjust some of the variables in the code to adjust where the hands are displayed.
Glad you enjoyed it!
Your site looks interesting (the pictures anyway)
