Cabling up the Keys

A small step today. I’ve removed the old bundle of cable and replaced it with a ribbon cable. Its a twenty strand flat ribbon, I’ve used thirteen strands for the keys and one for ground leaving six wires unused. I’ve left them as part of the cable on the grounds that they might come in for something later on.

Electronics – First Steps

The pedal board is ready with all the parts cleaned and screws tightened. I have a bundle of thirteen wires, one for each pedal. I’m planning to convert the input from these wires into a midi output. I’m using the Arduino Uno board to convert between the two. Rather than clogging up all the arduino inputs with wires I’m using a pair of PCF8574A port expander chips to encode the keyboard inputs.

The white wires in the above diagram are all inputs, sixteen of them, three spare. the diagram above was prepared using Fritzing, a fabulous open source tool for circuit design.

Here’s the result  set up on a breadboard.

I’ll be testing this out with a few jump leads before wiring in the keyboard wires. Code next. Meanwhile, I’m thinking of replacing the bundle of cable with ribbon cable which would be easier to connect to the completed circuit board.

Sparkfun Midi Shield

I ordered the Sparkfun Midi Shield from Amazon for a bargain £15. The postman brought the neatly packed kit the next morning. Time for a bit of soldering. Sparkfun’s kit is designed to plug into your Arduino board ready for some MIDI programming. All the surface mount devices are already soldered into place. The remaining parts need to be soldered by the purchaser. Here’s what comes in the pack.

There’s a pre-soldered board, three click switches, two MIDI sockets and a couple of rotary pots.

I also have a set of header pins at the ready – not included in the kit.

There are no instructions in the pack so here’s how I put it together.

Solder the two sockets into place, I used masking tape to hold them flat to the board as it was being fixed down.

I then soldered in the three switches and two rotary pots. There are a couple of large tabs on the pots. I soldered these down as well just to hold the pot into place.

Last step, adding the header pins. To make sure that they are lined up accurately for the board, I started with rows of pins, cut to length, fitted into an arduino. 

To finish off, I dropped the shield into the pins and soldered it down.

Done! Next, testing.

Home Improvement Projects

There are several reasons why you might want to borrow money for home improvement, whether or not you were to use a “piggyback” loan (which is a loan that you combine with someone else’s to finance a particular type of home improvement) or whether or not you’re just financing your new home for an extended period of time.

 Home Improvement Costs Increase the Value of Your Home

The sooner you complete home improvement projects, the sooner your home will appreciate in value. Simply put, the longer you finish the home improvement, the higher the value. Visit the SoFi website and get all the details you need to know.

This is because your home improvement projects often add value to the home. The home improvement itself creates value in the home as well. Furthermore, they increase the value of your home because your home improvement will take less time to complete, allowing you to more efficiently use your time to invest in other areas of your home, such as vacations or home improvements that add value to the home.

Home Improvement Costs Can Save You Money

Once you complete the home improvement projects, you’ll use less materials to complete the project. So you’ll save a significant amount of money by using a piggyback loan to finance the home improvement. The savings can add up quickly, particularly for big projects. For example, for a remodel of your kitchen, you can look at saving $5,500 if you use a piggyback loan.

3. Home Improvement Costs Can Improve Your Credit Score

Home improvement projects are often high-interest and carry high interest rates. If you borrow money to complete a major home improvement project, your rate of interest will be higher. But, if you use a piggyback loan, you can save interest, since you’ll be borrowing less money and paying more interest.

The result is that you’ll be able to get a better credit score. The result of using a piggyback loan is the same as borrowing from a credit union to make a down payment on a house. You’ll use less money to start with, which will lower your monthly payments. This will lower the interest rate on your loan, which will make it easier for you to pay off your loan in the future, resulting in a higher credit score.

4. Home Improvement Costs Can Improve Your Credit Score And Improve Your Credit History

Because you’ll use a piggyback loan to finance the home improvement, you’re already earning on your loans. However, using a piggyback loan isn’t limited to just paying off your loans. You can use it to improve your credit score. In addition to getting a better credit score, you’ll also likely improve your credit history by repaying your loans in full.

5. Home Improvement Costs Can Lower Your Monthly Payment

If you decide to use a piggyback loan to fund your home improvement, your payment rate will likely be lower than you might expect. To use a piggyback loan, you can choose one of the following rates:

Annual Percentage Rate (APR). Like a personal loan, piggyback lenders also have an annual percentage rate. If you agree to a monthly payment based on the rate that the lender’s offers, you can expect your payment to be lower than what you would pay without using the piggyback loan.
