If you’ve read much of this blog, you’ll have noticed that something I like to do is test ideas on simple breakout boards before implementing them into larger projects. If something goes wrong, I haven’t wasted a bunch of time/money on it. And if something goes right, then I’ve got an example that I can keep around which will help next time I need to implement that particular part. This post shows my breakout of the NCP1402 boost converter that takes inputs from 1-4V and outputs 5V at up to 200mA.
I’ve become obsessed recently with getting perfectly clear ice for my drinks. Here are my experiences getting almost perfectly clear ice spheres. The beginning of this post will talk about how to get clear ice, then how I progressed through cubes, and eventually how to get clear ice spheres every time. If you just want my unique method, feel free to jump down to the bottom. Continue reading “Perfectly Clear Ice Spheres”
Part of a robot controller I’m currently working on involves using some motor controllers. Since this robot controller is expensive and I’ve never worked with h-bridges (other than in professional products) I decided to make a breakout board to test it rather than risk making a stupid mistake on the robot controller. Luckily, it all worked perfectly so I’m sharing it with the world so that other people can learn from it. Continue reading “TB6612FNG Motor Driver Breakout Board”
One of the projects I’m working on is a robot that has reflectance sensors around its circumference. I had trouble finding sensors that would work in the 0.25-0.75 inch range but eventually found the RPR-220. To mount this sensor, I made a breakout board with space for resisters and connections for positive, negative, and signal. Continue reading “Using the RPR-220 and a Breakout Board”
The best tip I can give for thesis writing is to use Latex. For large documents it will be far easier to use and look much better in the end. However, there is a bit of a learning curve with Latex and it does so much that it can sometimes be difficult to even know all the cool things it can do. This posts will cover some of the Latex tips and tricks I’ve learned while writing my thesis over the past
month year way too long. I’m not going to include all the stuff you usually see like how to include a figure or how to make things bold. I assume that you know how to use google and there are thousands of pages of tutorials for those common items. I’m just going to be discussing the lesser known tips that I found helpful for long documents like a thesis or dissertation.
In this installment, I’ll show the big and small changes necessary to upgrade this photo. It’s got your normal adjustments as well as some gradients and brushes.
I’ve recently switched from Aperture to Lightroom and have been forced to learn a little about color spaces because of this. Today, I’m going to keep things simple and only talk about three different color spaces (SRGB, Adobe RBG, and ProPhoto RGB) and which ones you should use at each point of your workflow.
