I've finally finished editing an update video on my ASHP! This video was supposed to be a spring update, better late than never! TLDR: It kept us warm and got a SCOP of 4+ 😃 youtu.be/kkNx2oSO-S4
Our new emonPi2 6 channel energy monitor is now available to order! 🎉 #opensource #openhardware shop.openenergymonitor.com/single-phase-6…
Soldering? So passé! @electrolama No-Solder Multiprotocol Sensor Kit with the new @EspressifSystem ESP32-C6. Will go up on lab.electrolama.com at some point.
TLDR: it's working well, our house is constantly warm, it's costing a fraction of the amount of our old LPG combi and creating far less Co2 in the process 👍
For anyone interested in how a ASHP will perform heating a 200yr old end-terrace house with solid stone construction and providing hot water, here's my data so far from I'll update it periodically over the winter⚡️🏴 #EnergyTransition
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! ⚡️
Working on Humble iCE (FPGA board) RP2040 firmware using the C SDK. SWD is unreliable with these kind of wires. Need to build a better cable…
I've just been informed by a builder that integrated solar PV is now cheaper per m^2 than slates, so it's a no-brainer to install integrated PV on all new roofs! 👏
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/collections/us…
The cat is out of the bag: the new LimeSDR Mini v2 will switch to a @latticesemi ECP5 FPGA with 44K LUTs! crowdsupply.com/lime-micro/lim… #softwareDefinedRadio #OSHW #OpenSource
A new old stock DEC J-11, 18MHz PDP-11 microprocessor, one of the most beautiful chips ever made. Seemingly in production until at least the late 90s. Hopefully this will end up in a DIY project at some point.
New project! zoe2 is a @Raspberry_Pi addon that gives you a nice 2.4GHz and sub-GHz radio along with RTC for offline timekeeping and PoE Power. Read all about it in our March 2021 update at: electrolama.com/lab-notes/marc…
🎉 Celebrating another milestone this evening: 3000(!) zzh sold! 🥳 Thank you to all our customers, friends and folks at @Tindie who've turned this tiny little side project into a decent sized manufacturing/logistics operation 🙃 More projects coming soon! ⚡️
New stock up on @tindie, with revised pricing thanks to economies of scale! ⚡️
Back in Stock! zzh! CC2652R Multiprotocol RF Stick tindie.com/products/elect… by @electrolama
Nice milestone hit, 1000 orders on Electrolama @tindie store! Thanks for your interest and watch out for the new boards coming soon ⚡️
The first batch of zzh boards have arrived in London and they are ready for sale ,more zzh boards sent to Electrolama yesterday.
I wrote a quick blog post (martinellis.me/posts/2020/03/…) about @electrolama's TI CC2652R based ZZH board when I got my hands on a prototype a while back. Looks like they are back in stock and trending on tindie: - tindie.com/products/elect… #zigbee #CC2652R #zigbee2mqtt
