Taking apart a Intel dotstation

After many years of use, my dad decided to give up on the intel dot station that he possessed, and I decided to make good use of it (read as taking it apart). Getting to open it was in itself a challenge due to the custom screw head that they had on the back panel, and I had to prise it open. The device is built on a metal chassis at the base enclosing the processor, HDD etc, on this is placed a 14" monitor, with the left of the monitor taking a PCB (the SMPS) and the right is another PCB (the electronics that takes a VGA input and converts to analog signals for running the CRT). That is it.... A very cool design, I though, for a PC designed 8 years ago. Well, with that done, and analysing the various piece of hardware, I decided to throw it all, except for the chassis and the HDD (that has a puppy linux inside). I hope some day to find a processor that will fit into the chassis and a SMPS and run a bare-bone PC.

Rain water harvesting, phase 1

Completed a part of my RWH project for my home. Included a new sump of 2700 litres, and re- routed the piping to collect all the water from my flat roofs and direct to this sump. Also designed and implemented a filter with a carbon bed, pebbles and sand filtration. Plan to use the collected water for gardening and household use.

#IoT

August 2017: I began reinvesting my time with electronics and hobby projects to explore arduino and raspberrypi. In three months, managed to build a proto to asses my hybrid solar generator, monitoring panel and batteries! It was a great success. April 2018: Revamped it with a new model with wifi capabilities and updating data to thingspeak iot. Well, the purpose of building that was to understand "Why my Solar Generator, with four 100 Ah batteries, gives an average back up of 50 min as compared to the UPS, with one 150 Ah battery, which gives a back up of 7 hrs 20 min (for similar loads)". The voltage traces of the respective batteries as they discharge and charge are as below. Turned out that the issue was with one of the batteries, but the data helped get the battery replace under warranty
