I recently brought 3 of these NodeMCU dev kits for playing around with, building some remote sensors over WiFi. The options are huge with 10 GPIO pins to play with.
I2C - Sensors
PWM - Senors
1 wire - Sensors
GPIO - connect relays etc..

How to Unlock the NVMe Performance on the Lenovo Y700
Posted on 23rd Feb 2017 08:14:31 in SSD, NVMe, Laptops, cryptocurrency
In previous blog posts about the Lenovo Y700 where we added a high performance NVMe SSD in my case a Samsung 950 pro, others have since added Samsung 960 evo's and pro's. The draw back was that performance was capped at ~1600MB/s which leaves a fair amount of performance unavailable on these high performance SSD's. The issue was tracked down the DMI link speed being set to PCIe 2.0 speeds, this was what was causing the performance cap or around 1600MB.
After Lenovo refused to change the setting, their is finally a work around to set the DMI link to full speed (PCIe 3.0) this fully unlocks the performance for these SSD's. Thanks to our friends over at MDL.

Raspberry Pi Resistive Soil Moisture Sensor

One of the drawbacks of watering the garden on a timer basis is that you inevitably end up watering when you don't need to like after it has rained. This always bugged me as my rain water storage of 2000L would always run out over summer. So anything i can do to water more intelligently and conserve water is a bonus.
Watering the garden based on need, measuring soil moisture to make the watering decisions.
