Arduino have just announced a bunch of new boards, including one with an on board FPGA chip (plus a SAMD21 Cortex-M0+, plus an ESP32 WiFi and Bluetooth Module). A Field Programmable Gate Array (FPGA) chip is possibly the most impressive piece of electronics going. They are essentially a way of creating entirely custom digital electronic circuits (resistors and transistors) all inside a tiny chip, and completely reprogrammable – genius!

After the bearing failure on my MR2 Turbo, 3SGTE, I’ve been investigating bearing failures.
There are a couple of very good guides which provide an example of a number of different bearing failure modes.

After dismantling my 3SGTE, we found that all of the bearings had picked up and one big end had spun completely and ripped the bearing in half. Most of them looked like this:
The crank was also scored and I suspect the con rod with the spun bearing my have gone oval too.
So, I have just bought a lovely new HTC One, and am mostly happy with it, although the screen is a bit too big to use one handed and the network connection seemed a bit slow. I still haven’t managed to do a proper test o. the mobile network connection, but I have gotten to the bottom of why the WiFi connection was so slow.
