Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. Please clarify your specific problem or add additional details to highlight exactly what you need.
1) Running the transformer at maximum current (1 A average) is doable, but not a great idea.
4) With a decent input voltage and 1 amp output, your 7815 is going to dissipate more heat, and without a proper heat sink it will fry.

The oscillating blade creates a high velocity flow stream emanating from the blade's leading edge. This is the price (excluding shipping and handling fees) this seller has provided at which the seller has sold the same item, or one that is virtually identical to it, in the recent past. International Shipping - items may be subject to customs processing depending on the item's declared value.
Your country's customs office can offer more details, or visit eBay's page on international trade. Estimated delivery dates - opens in a new window or tab include seller's handling time, origin ZIP Code, destination ZIP Code and time of acceptance and will depend on shipping service selected and receipt of cleared payment - opens in a new window or tab.
This item will be shipped through the Global Shipping Program and includes international tracking.


Will usually ship within 1 business day of receiving cleared payment - opens in a new window or tab. We will refund your money if the item you receive doesn't work at all unless it was listed as being in unknown working condition or not in working condition. The p-p ripple at 100Hz will be of the order of 10 volts (won't actually be that much because the regulator will drop out). The fan blade requires an oscillating drive signal which matches the resonant frequency of the fan blade. The module accepts a wide range of line voltages from 85 to 264VAC ensuring its operability from worldwide power sources. The "off" amount and percentage simply signifies the calculated difference between the seller-provided original price for the item and the seller's current discounted price. If you'd like to get the additional items you've selected to qualify for this offer, close this window and add these items to your cart. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. Contact the seller- opens in a new window or tab and request a shipping method to your location.
The buyer is responsible for all shipping costs, to be determined by location of buyer and weight of item sold.
16VAC output (transformer RMS rating at full load) might be okay if you don't allow for much mains variation (-10%) and have a big filter cap. Design to withstand the elements, the power station has a wide operating temperature range and will work in the sun and in very severe field conditions.


If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
See the How to Ask page for help clarifying this question.If this question can be reworded to fit the rules in the help center, please edit the question. If you have a scope, look at your output with a 0.6 A load, and I'll bet you see dips in the output which occur at a 120 Hz rate.
Safety wise, the power station comes with short circuit and over current protection providing peace of mind while at the track, shore or flying field. Currently, even with your changes, it's not optimal, as your regulator is having to do a boost mode conversion to up the 12V given to 15V, but of course, at the expense of some amperage.
Transformer ratings aren't like power supply ratings - you can often get more than rated output. Refer to WhatRoughBeast says, keeping in mind that you should always use components with a bit of headroom over their max rating. Of course, at some point the transformer starts smoking, but that's called a learning experience.
