Sewer line replacement work in May went pretty well, and the work was completed, inspected, and filled in within about two and a half weeks which was pretty speedy completion of work. The house has been put back together again and we were also able to address a leak in the stack from our guest bathroom at the same time. It’s great to be able to make use of all the houses plumbing again.
As the weather warms up, we took down the storm windows but are in need of window screens for all the windows. A likely job in the near future will be building frames and screens for the windows that we want to leave open in the summer. I also noticed that a number of the windows need their glazing fixed, so that’s also now on the to do list.

In late May I finished the coding for my new Melodic Orchestration module to function as a clone of the Roland Aria J-6, and began work on a tuning program to make it easier to tune the synthesizer. Now that these are done, I’ll either try to clone the Moog Subharmonicon or the Stocastic Instruments Inspiration Generator next.
I’ve started the circuit board design for my YM3812 synthesizer, now that I’ve tested the Melodic Orchestration since the YM3812 synthesizer will share a lot of common design patterns with the Melodic Orchestration.

Speaker
Status: Built
Since I enjoy taking my synthesizer out of the house and outdoors, I decided that it would be helpful to have a built in speaker in my case rather than having to remember to bring earphones when I left the house with my synthesizer.
My design is copied off of the Clacktronics Mini Speaker Kit which is a very simple and nonsense speaker in only 6 HP. There isn’t amazing low-end on a speaker this small, but it’s great for portability and being able to quickly listen in on a patch.

At the end of April, we realized that the 110 year old cast iron sewer line beneath our house had collapsed, so May’s project around the house will be cutting through the basement slab and trenching in a new sewer line from the front to the back of the house.

In April I got the circuit board for the Melodic Orchestration module I designed and assembled them. So far it seems to be working fairly well, with a couple of minor flaws that I can probably kludge on to the circuit board to get it working as intended. My first program that I want to code is a Roland J-6 emulator, which plays arpeggios and chords.
I also want to get the circuit board design underway for my YM3812 synthesizer, which I’ll base off of Tyler Klein’s design, and will leverage some of the same circuit design as the Melodic Orchestration for the display and control interfaces.

One of the biggest steps you can take to ensure your security online is to keep the software on your devices up to date and install any software updates that come out. This advice doesn’t just apply to your computers and phones, but also internet of things devices like a Raspberry Pi or BeagleBone Black. Luckily this is an easy process with the help of one important software package.

One of the best ways to understand data is through the use of descriptive statistics, figuring out the minimum and maximum values, the median value, and the quartiles. When you’re working with smaller datasets this is easy, but with larger datasets you need to parse a lot of data to get these metrics. Luckily, you can use SQL to get descriptive statistics for your data directly from the database.

A key component in data acquisition or reporting is the ability to trigger your script to run at a set time each day. Whether you are attempting to download the latest stock prices or update corporate earnings reports, once you’ve created the script to do the actual work, you need to find a way for it to be run on the correct schedule.
