Can I buy the guide as a hard copy?

No, but this is coming soon...

Can I copy / print out / share my idiot's guide?

The PDF file is open and unprotected - so yes, feel free to keep multiple copies on different PCs and print out a copy for every room in the house! All I ask is that if you want to provide a copy to >1 person, please buy the same number of licences or contact us to discuss a site licence.

What if I still don't understand how a PID controller works after reading this guide?

I'll cheerfully refund your money.

Do I need to have a PayPal account to buy the Idiot's Guide?

No. Although we use PayPal as our secure payment processor, you don't need a paypal account. You can use any credit card through the paypal site for a one time payment without needing to create an account.

The picture below shows where to click on the payment screen if you don't have or want a paypal account!
