Learning to play on electronic drum set- good or bad idea?
Something along the lines of Roland HD-1. I figured it would save me some space and my neighbors wouldn’t hate me as much. I’m wondering if it would be counter-productive to learn on an electronic as opposed to a real set. Seems like they would have a totally different feel.
How do I set up cell phone service for someone without them knowing?
My brother is always complaining about his cell phone and service and it expires soon, so as a Christmas gift I want to get him a new phone and service with AT&T. Will they let me purchase a new phone and set up a service without him and then maybe he can come in and activate it after wards? How would this work? Would I still be able to buy the phone at the discounted price?
Block Diagram
Block diagrams are used to understand (and design) complete circuits by breaking them down into smaller sections or blocks. Each block performs a particular function and the block diagram shows how they are connected together. No attempt is made to show the components used within a block, only the inputs and outputs are shown. This way of looking at circuits is called the systems approach.
Power supply (or battery) connections are usually not shown on block diagrams.

Regulated Power Supply Block Diagram
This is the block diagram of the most of regulated power supply.
Notes:
- Transformer – steps down 230V AC mains to low voltage AC.
- Rectifier – converts AC to DC, but the DC output is varying.
- Smoothing – smooth the DC from varying greatly to a small ripple.
- Regulator – eliminates ripple by setting DC output to a fixed voltage.
Audio Amplifier Block Diagram
This is the block diagram of an completed audio amplifier from input (microphone for example) to the output (loud speaker). You may add some additional block like an equalizer between pre-amplifier and tone control, or add a crossover between power amplifier anf loudspeaker.
Notes:
- Microphone – a transducer which converts sound to voltage.
- Pre-Amplifier – amplifies the small audio signal (voltage) from the microphone.
- Tone and Volume Controls – adjust the nature of the audio signal. The tone control adjusts the balance of high and low frequencies. The volume control adjusts the strength of the signal.
- Power Amplifier – increases the strength (power) of the audio signal.
- Loudspeaker – a transducer which converts the audio signal to sound.
