- There was a large electrical fire where Chris lives in Chicago.
- Chris is launching a new course for Contextual Electronics making a board with Bluetooth and cellular.
- This lead to Quectel sending him a development board for the EG91
- DB9 is still alive! It was paired with a RS-232 chip on the dev board Chris got
- Dave is doing a 5 part series about programming the 3 cent micro
- The first one is about making the programmer
- Dave wants to call out the “$0.01 linear regulator”, the SSP6206
- The cheapest regulator on Digikey is the NCP115, but it has a PITA package to solder (1mm x 1mm!)
- Carl Bugeja calls out a haptic driver (meant for the buzzer on your cell phone) that can be used as a small motor driver.
- Chris has been dealing with smaller pitch parts using his new microscope. This model was recommended in a recent Voltlog video about microscopes.
- XC6206 is another low cost linear regulator.
- CE forum post about microscope recommendations
- HEPA fume extractor video
- Alvaro explains his part setup at home
- Review of a $100 handheld scope
- Dave has also done a cheap handheld scope review

Thanks to Mark Ittleman for the image of the pita on a conveyor
Chris, you didn’t say who is this new cheap FPGA company/chip.
I learned how to solder about one and a half years ago, and I’ve been constantly pushing how small I could go with manual hot air reflow. The LDO package you guys were talking about was the breaking point for me. I used TI’s LP5907 LDO with that package (they call it X2SON), and it was a nightmare. After a while, I gave up and switched to their SOT-23 version. It’s been smooth sailing ever since. I liked the small footprint, but I don’t miss multiple reworks to get it to solder properly.
