Weather Station Sensor module v1.1

More background of this project to be found at: https://sourceforge.net/projects/jipshome/

Uses two Boscam RX5808 modules and the diversity controller designed by youtube user RCModelReviews. Includes a switch (SK23D07) that allows direct manual access to the audio/video signals from receivers 1,2 or diversity.

Left position = signal from left antenna, right pos = right antenna, center pos= AV signal as determined by diversity controller.

If you can’t source a switch, simply bridge the upper middle two (video) and lower middle two pins (audio). This will direct the AV output from the diversity circuit to the output

There is another (earlier) version of this board with a LM117 voltage regulator. I have removed it as I have read that it gets far too hot even with 2S. In this case the 22uF 3216 tantalum caps are not needed.

You will need a 5V input (some say that you can go down to 3.3V, but you will have to experiment with that). If you decide to use an external voltage regulator and it has a diode already built in, you might bridge the pads for the diode.

If you need more channels/bands you can open the RX5805 Module and connect BX and S to the corresponding spots on the PCB. Below is the website by der-frickler where he explains how he did it.

Here is a picture showing where the leads have to be soldered to (Pins 8 and 48, big yellow circles):

If you f*** up like I did the first time and rip the pads off, you could try soldering the leads directly to the chip (small yellow circles)

*rled = resistor for LED, has to be calculated depending on LED-specifications and voltage input.

Designed for OPA827 and OPA 4227, this circuit amplifies a very small photodiode current input to a +-15V voltage output. OPA827 is chosen to minimize bias current, offset voltage, noise density and price!

This is an update on the original BLF SRK FET driver which was designed by Mattaus, and inspired by the work of Comfychair and several other BLF members.

Breakout board for four popular motion sensors including the Invensense MPU9250, ST’s LSM9DS0, Maxim Integrated’s MAX21100, and Bosch’s BMX055. Intent is to characterize the performance of the accelerometers, gyros, and magnetometers on these sensors under the same conditions. Separate analog and digital voltage sources to probe effect of digital signal line voltage and noise on data jitter. At least one interrupt broken out per sensor to allow comparison between polling and hardware interrupt on performance. Is there a significant difference between these sensor elements in terms of jitter, drift, stability, and response time? Let’s find out…

Cost: $0.80 for three.

This is a Raspberry Pi 2 breakout board. All of the pins have been broken out in a single row and labeled. Pin one at top and pin 40 at the bottom. This PCB is breadboard friendly and should fit most enclosures that have a slot in the side for a ribbon cable. (PCB is untested) About $8.17 per board.

Simple breakout board for the ESP8266 chip to provide wifi capability to the Teensy 3.1. Designed to take power from VIN via USB or LiPo battery and convert to 3V3 with a TLV7333 300 mA voltage regulator. Also on board is a Macronix 4 Mbit MX254006E SPI Flash memory chip. Small rgb led indicates power on, pcb antenna matched to 2.4 GHz. Can use either 26 or 40 MHz Seiko Epson crystal. The board has the same eight pins as the cheap Chinese modules as a first cut to see how hard it is to add wifi to Teensy 3.1 projects. The board is designed to solder directly on top of the Teensy just above the USB plug.
