Dlexa's DML Frame and Cabling HubThe Dlexa DML speaker sits inside the escallonia hedge at the edge of the sidewalk. The DML is inset into the frame and protected by bug screen. This should be far enough from the sidewalk to protect it from curious hands. A permanent notch is cut into the hedge (mostly the 2nd bush in) to keep the hedge from touching the frame. The plywood plate keeps branches away from the back of the frame. The pot holding the dragonís head (with swivel motor) is placed on the top of the frame. A power, cable and WiFi hub is on the shelf below the speaker.
Wifi Signal InterferenceThere are perhaps a dozen microcontrollers in the hedge so RFI and anything that blocks an RF signal is a problem. ESP family devices (ESP8266, ESP32-CAM, ESP32-S2) are used to manage sound and light effects and they only have one inch square antennas. Keeping the interference to a minimum and providing a clear signal path requires practices that border on superstition.
Wifi Signal StrengthOn Dlexa's DML shelf is an old router. This provides a local strong signal for the controllers. Dean happened to have a box of old Siemens Gigaset SE567 DSL routers so that was used. [Released 2006, 2.4Ghz 802.11b/g with four 100Mb but you can still buy one]. It is connected via a CAT4 wire into the garage for network/internet access.
One Year PlanIn summer 2023 microphones, speakers, cameras and proximity sensors for Dlexa and Pearl will to be mounted on the growing hedge. At the start the hedge will be "talk only" with audio clips played when a visitor arrives or takes an action (like ringing the gong). Cameras and microphones will only be monitored for quality.
Next:In many cases rough documentation on eyes, ears, voice and light with be posted before their installation with final versions posted after the effect is operating. The "final" versions may not be the "installed" versions. More of a bridge between what was done and changes planned for a 2.0 installation.
