Announcing Electrolama Community Projects - have a cool idea and want to contribute to the Open Source Home Automation community? We'll send you free hardware to hack on! Terms and discussions at github.com/electrolama/commu…
We're now on mastodon.online/@electrolama for our friends who're leaving Twitter.
We've just run out of zzh kits but more are being manufactured as we speak -- photo of some fresh panels we received this morning attached.
We expect to have them back in stock w/c 25/07. Join waitlist at shop.electrolama.com/collect…
New batch of zzh almost here!
We're not used to hot weather around here so things have been a bit broken these past few days, lots of "Operational Delay"s everywhere 🫠
Just the final hop now, join the waitlist if you'd like to get a notification: shop.electrolama.com/collect…
zzh is finally back in stock! Unfortunately we're going to have to increase the price a little bit, as costs are increasing rapidly and chip supplies remain scarce. We'll keep old pricing up until the end of this week, grab one at a discount now at shop.electrolama.com/collect…
It's pretty hot in London today, perhaps a good day to do some stress testing on the upcoming zoe2. Haven't yet pushed the PoE module to its limits yet but so far so good! Sensors used are INA260 and AHT20, connected to the Pi using the qwiic compatible connector on board.
zzhp Collector's Edition. Limited to 100 pieces, individually numbered. Transparent plastics and a custom pink soldermask.
Coming (very) soon! ⚡️
In the meantime, we are offering some reworked kits at a cool 30% discount at shop.electrolama.com/collect…
These are all reworked in our lab and fully tested, including RF output levels, before being re-packaged.
Reduce e-waste and grab yourself a bargain at the same time ⚡️
We've been working on quite a few things behind the scenes and will be revealing them all in the next few weeks. Watch this space ⚡️
Testing the RF PA output power of zzhp pre-production samples. Theoretical max +20dBm, observing between +17-19dBm in continuous TX. Taking the inherent losses into account (silicon to package, package to PCB, balun/filter/RF connectors etc), happy with these numbers ⚡️
These results are actually better than the TI reference designs, not through any magic though as it is simply a tighter layout, we use very low tolerance (mostly ±0.1pF) and very small (0201) passives and have impedance controlled high quality PCBs.
