FNIRSI sent me some bits - so I thought I'd solder up some more boards from https://www.PCBWay.com/?from=atomic We're testing out a new USB soldering iron and a 3in1 Oscilloscope. Both these items came from FNIRSI who seem to be doing a lot of interesting things. You can get the 3in1 Oscilloscope here - https://s.click.aliexpress.com/e/_DFWgn7h And the soldering iron here - https://s.click.aliexpress.com/e/_DkUNMlD --- If you'd like to help support the channel and help me buy more nonsense - I have a Patreon page: https://www.patreon.com/atomic14 We've also got a shop now! https://shop.atomic14.com And if you're shopping on AliExpress or Amazon then if you click on these links I will get a little bit of affiliate money: Aliexpress - https://s.click.aliexpress.com/e/_Ac05mF Amazon - https://www.amazon.com/?tag=atomic14-20 You can also join us on Discord here: https://discord.gg/h2DDnDdjD2 There's also the Atomic14 newsletter here: https://atomic14.substack.com/ And don't forget about the MakerNews newsletter - https://makernews.substack.com/ ... https://www.youtube.com/watch?v=RFaUuWfS5cw

I've been playing around with one of these E-Paper displays. I've got the LILYGO 2.7" ePaper Plus Module . The classic thing that people seem to do is get a weather display up and running - so I thought I would do the same. Thanks to PCBWay for sponsoring this video, PCBWay offer PCB Production, CNC and 3D Printing, PCB Assembly and much much more. You can find their details here: https://www.pcbway.com/ There's a really nice library on GitHub by G6EJD that everyone seems is using. This already has support for a whole bunch of ePaper displays including the Waveshare 2.7 inch display which is the one that is used on the LILYGO board I have. https://github.com/G6EJD/ESP32-e-Paper-Weather-Display Most of the instructions are around using the Arduino IDE but as regular viewers will know I'm much happier using PlatformIO, so we'll get it up and running there. You can find my repo here: https://github.com/atomic14/ESP32-E-Paper-Weather And the demo code from LILYGO here: https://github.com/LilyGO/TTGO-T5S-Epaper You can order the module I'm using here: https://s.click.aliexpress.com/e/_AZRYxj --- Want to help support the channel?

We're doing a deep dive into deep sleep! Thanks to PCB Way for sponsoring the videos - www.pcbway.com The ESP32 e-Paper weather display lasted exactly 2 months on its 1000mAh battery. It achieves this by spending most of its time in deep sleep, only waking up every 30 minutes to get a fresh forecast and update the display. We're going to look at: [0:00] Intro [1:33] How to get into deep sleep [1:42] Waking up by using a timer [2:56] Waking up by GPIO pins (single and multiple) [5:26] Waking up with the touch sensors [6:13] How to know why you were woken up? [7:37] How to persist state during deep sleep? [8:24] How much current do we use in deep sleep? It's pretty interesting stuff and opens up some great possibilities. Here's a link to one of @Andreas Spiess videos (the guy with the Swiss accent) https://www.youtube.com/watch?v=ajt7vtgKNNM he's got a bunch more videos measuring different ESP32 boards - definitely worth having a watch. ... https://www.youtube.com/watch?v=YOjgZUg_skU
