This week marks the start of the 2015 Holiday Shopping Season. Being a short week for me, I thought I’d offer up some gift suggestions for engineers.
When you need to buffer the output of an R-2R ladder or an RC filtered PWM signal, an op-amp is a single chip option. Unlike a discrete NPN transistor like a 2n3904, there is a lot going on inside of an LM741—or any op amp for that matter.
What if you could look inside of the op-amp? Wouldn’t it be cool to see how many transistors make up these small chips?
After fighting bugs, bad connections, and burned out chips your project is working–or even done. The next step? Record a video, edit it, and upload it to YouTube.
Too many steps? Then maybe you just want to do a Periscope demo. Within seconds, you can be broadcasting your project to the world.
This past weekend I tried my first couple of scopes. The first Periscope “demo” was me soldering together a Three Fives from Evil Mad Scientist Labs. The others periscope demos were 3d printing related.
When it comes to a hardware project demo, I see some challenges. Check out these five things to watch out for and, if you’re interested, you can watch my soldering Periscope demo.
What is more American than an Apple Pie? Why, a Pie designed in California, made in China. This is one pie I’d like to jailbreak. Is applying too much heat to this pie considered an upgrade? Okay, that’s all the lame puns I have for this laser cut pie. Evil Mad Scientist Labratories provides a tutorial on how to bake a Mac Mini Style Apple pie, complete with Laser Cutting Instructions. Yeah that’s right, a laser…
