This is a post to link together various past/future ones into a single story. Understanding time series and various concepts like stationary, seasonality, trend and additive/multiplicative series. Forecasting with Facebook Prophet Forecasting with SARIMA Forecasting with LinkedIn Greykite Trying out Auto-ML with AWS and GCP Auto-ML with Azure How to understand and explain accuracy of forecasts There will probably be some more related posts over time and I will try to keep this index updated!

So far I tried running models in AWS SageMaker and used the OpenAI APIs. There are some local options too and with only a CPU. …

My social feeds are full of generative AI so with fomo in mind here is an attempt to create my own chatbot, using OpenAI APIs, and augmented with custom data. There are way too many options, so this exercise has been about figuring out the tools to pick and stitching…

Yes this is not new anymore, but I’m finally getting around to doing this for myself! There are simple apps anyone can use, however in this article I explore using some models, deploying them myself and then generating images and learn about prompting. Hugging Face lists numerous text-to-image models so…

This story is part of a series. See this starting page for links to other lessons. In this lesson we will create a night light that turns on when its dark and turns off when there is light. Recall Lesson 4 where we used a LDR that made a light…

This story is part of a series. See this starting page for links to other lessons. In this lesson we will learn what is a NOT logic gate and build it with a transistor. In this circuit when you send electricity then the LED turns off and when you don’t…

We use a light sensitive component to control a LED and buzzer using a transistor as the switch.

This story is part of a series. See this starting page for links to other lessons. In this lesson we will learn about transistors and how they can be used as a switch. Please see previous posts for components we have already used in the past. The only new component…

This story is part of a series. See this starting page for links to other lessons. In this lesson we will create a circuit so that with a switch you can turn an LED on/off. As a bonus you can optionally add a component to control the brightness. For a…
