Here is a quick 3D printed object to solve your common problem – sound directed to the wrong area – so you don’t have to cup your phone when you talk or watch your favor video or doing Facetime on your iPhone.
For ~$20, you can turn your Ryobi 18V battery into a power engine for your IoT projects or a mega battery charger that would last you many days out in the camp or where ever you choose to be without AC power.
Here is the link to the 3D-printed power clip: ~$5
12V Car Lighter Socket/Plug: ~$6
24V-tolerant USB Car charger: ~$9
Here’s a quick tip – make yourself a shoehorn pant lifter. Why? Because it’s the best thing since the sliced bread. Probably not, but it’s pretty close. When I leave home for office, I used to struggle with shoehorning my feet into the shoes because I carry my laptop and other things and my pants tend to get caught in the shoe. This shoehorn pant lifter allows you to shoehorn your feet without catching your pants in the shoes. Try it! You might like it!
Here’s the 3D file for you to modify or print directly.
This is my newfound interest – IoT or Internet of Things. I have been taking in all the Maker movements and decided to do something about it. This particular project Raspberry Pi Zero W was the first of the many IoT projects I plan to do and bring you along in my journey. Raspberry Pi Zero W is one of my favorite controller because it’s compact, inexpensive ($10) and with built-in Wifi and well supported by the Raspberry Pi community.
I wouldn’t say this was challenging to me as I have done more difficult and complex hardware design in my career as a hardware development engineer, designing the big-iron mainframe computer and multi-CPU servers. But this was probably more fun as I got to sense and control the real-life environment and it’s relative inexpensive to do.
I look forward to sharing more of this type of projects with you, in addition to all the “boring” book reviews, according to my daughter, I will continue to make.
