Automating IR AC/Heater with Raspberry Pi and Google

Objective Automate my existing apartment climate control system by adding a remote web interface to pre-cool my room on my way home during the summer and easy scheduling to warm my room before getting out of bed in the winter. AC interface Most Japanese air conditioner/heater units use IR controls incompatible with Nest so controlling over IR was the only option. Unfortunately reverse engineering the IR protocol would prove to be challenging. These IR remotes are completely different than those for TVs and other appliances. Most IR remotes send single commands like "on" or "volume up" but these AC units are stateless, it's the remote that has the brains, so each time a button is pressed the remote will send the entire list of settings values.  For instance, if you just press the button to increase temperature+1 say from 24 to 25, the remote will actually send [power:on, mode:heater, temp:25, air-speed:2, air-diffuser:on, timer:off...] I won't go into detai…

Erato Muse 5 True Wireless Bluetooth Earbud Review

True wireless earbuds are liberating. Going back to anything with wires will be frustrating especially in the winter when the cables have to wind around layers of clothes.
These Erato Muse 5 exceeded my expectation though my expectations were set pretty low from reading abysmal Amazon reviews for similar devices. Overall these have improved my listening experience though not without a few quirks, some of which may be intolerable for average consumers.
Pros: Decent sound qualityOutstanding battery life even without recharging in the caseLightweight and comfortable enough for long sessionsAdequate mic pickupFade-in effect when resuming from dropoutsEasy to power on/offAutomatically turns off when chargingCons: Fitseal sleeves didn't fit. Your results may varyWireless signal needs improvementPhysical buttons are uncomfortable to use while wearingInserting into the charging case takes a little skillStill pretty large and obviousSpecs (From Bluetooth Specification: BT Vers…
