On AliExpress you find cheap wireless (RF433) weather stations compatible with the ‘Fanju’ weather station model FJ3378/74/79C/65/89 (according to AE). Following is the description of the data transmission protocol.
An Arduino (Uno) shield for two stepper-motors, one Servo motor, and an alternative output. For the SphereBot, another Egg-Bot derivative.
This SphereBot is built with a retired Sparkfun Arduino Ethernet Pro board and the steppermotors from a 2009 Makerbot. Firmware and host sw (fork) from thunderbug1.
Download the Eagle schematics and board (ZIP 100kB).
I built the simple signal generator described in Electronic Design. The same circuit you find on ZL1NC and epanorama. Together with an Oscilloscope it can be used to find a cable fault as described in this All about Circuits article.
The 74AC14 SMD is mounted on the board its trace side. All other parts are through-hole. Most parts were salvaged from old electronics. You can adapt the PCB to your needs.
The OpenHantek GUI adds a bit more flexibility, e.g. export to PDF, PS, JPG or CSV data.
To enable wake-on-LAN over the Internet, the open hardware platform Arduino is used.
Not all routers support wake-on-LAN from the Internet to LAN. This depends on whether you can configure the ARP cache and send or forward a WOL broadcast package.
To support WOL, in this case on an Apple TimeCapsule, an Arduino Ethernet Pro board is used. Thus having a low-power device (Arduino) listening for WOL.
Both the Arduino board and machine to wake-up are connected via Ethernet to the TimeCapsule. The Arduino is powered using the TimeCapsule USB port.
For the few who consider using a USB Digital Storage Oscilloscope on Mac OS X. The Voltcraft (i.e. Hantek) model 2090 DSO can be used on the Mac in combination with Oleg Khudyakov’s HantekDSO (Linux) software.
