MiniMeter reads voltage & battery level over I2C thanks to the @ADI_News MAX17048🔋⚡️ I got tired of looking for the perfect LiPo charging solution for tiny projects so I built one myself! What projects would you power with #MiniMeter?
Alex Lynd@AlexLynd

My week was filled with chaos, but I finally got a chance to assemble & test the MiniMeter! 🔋⚡️ I'm finding this mini charger & gauge useful in space constrained projects, like my latest #CutieWardriver design 📡

Check out this cute ESP8266 Coffin Wardriver ⚰️📡!

@AlexLynd @lyndlabs @DevKitty_io Here's my little flashy coffin war driver using your design and code with over half of it uncommented so I can run it with no screen XD Not sure there's proper low voltage cut off (just under 3v) but it did run for about 7hours off a 600mah!!

🔋⚡️MiniMeter will be available on lyndlabs.io! Final design still needs testing, and I'm working on some cursed additions to the charging family. Follow @lyndlabs for updates & join the mailing list for updates on my projects!

My biggest #PCB design gripe is LiPo charging 😡🔋- especially when prototyping w/ #microcontrollers. There just aren't any drop-in solutions that charge & power on the same pin, let alone a castellated one! So I designed ⚡️MiniMeter⚡️- a tiny charger & I2C battery meter! ⬇️

Happy New Year! 🎉 As a self employed 20 year old hardware developer, 2023 kicked my ass. I had to take a break from posting but here's a look inside the chaos from my year! 🧵⬇️

I (was) excited to share that all backorders have been packed this week after receiving new parts - until I discovered that *EVERY FUCKING GPS MODULE* I ordered is counterfeit, and defunct. (60+ modules) Updates & investigation coming soon ⚡️

a video of the symptom: the #GPS only works when the antenna is unplugged - I've tried 3 different antennas and tested 20+ #counterfeit modules. I'm starting to think something is shorted internally 🧍

Started digging into these #counterfeit GPS modules, right off the bat I noticed that most of them use 2 resistors in place of the LR series #circuit. Some modules started working when I swapped in the proper inductor. Is this used for impedance matching?

Here's a fun way I discovered how you can identify real @ublox modules 📡from #counterfeit: the cheap plastic stickers shrink when re-flowed 🔥

Testing the new #wardriving 📡 firmware I developed for dnsdriveby.com this week, while exploring SF by foot! I took a short break from dev this week to host a booth at @OpenSauceLive but I'm jumping back in again :)

I've been testing external & internal storage for #wardriving this week on the #ESP32 🚗📡 The ESP32-S2 directly mounts as a flash drive (way easier than SPIFFS on the #ESP8266) - but to overcome the 3MB storage cap, I'm trying out SD Card passthrough 🖥️ Has anyone done this?

Your Nugget / DNS Driveby 🚗📡 kit now acts as a flash drive thanks to the #ESP32 Native #USB functionality! You can log #wardriving files to INTERNAL memory (space limited to 3MB), but in a pinch you don't need an external SD Card. 💻💨 Learn more @ dnsdriveby.com

I've been complete re-writing the #wardriving software for my dnsdriveby.com kits since 4AM this morning, including a port to the #WiFiNugget! 🐈📡 Coming soon you can also expect @wiglenet support, new UI updates, a web interface, and cats! 😺
