Verkoop kleine onderdelen / opening webwinkel

Onlangs was ik op zoek naar een alternatieve Wifi module voor mijn Airco, aangezien deze niet goed geintegreerd kon worden in Home Assistant.

Dat leidde er toe dat ik wel de software en instructies vond, maar geen kant en klare modules.

Ik kan me indenken dat voor sommige mensen het zelf bouwen van deze modules een stap te ver is.

Daarom heb ik mezelf voorgenomen om deze modules kleinschalig zelf te bouwen en te koop aan te bieden.

Daarom heb ik nu een webwinkel geopend waar ik dit soort onderdelen verkoop.

Home Automation Sensor Build Progress

I am working on sensors for my Home Automation system.

The system itself is running on Domoticz and for these sensors I have created a Database / Web-interface so the sensors can easily log the data.

Features from these sensors:

Humidity / Temperature / Light level / Battery Level / Window Status (Open / Close) / RSSI for Wifi.

They can retrieve Over The Air Updates and are based on the ESP8266 Wifi Chip.

Some issues I have crossed along the way are:

Battery drain –> Trying to solve by using Attiny85 to shut down ESP between runs.

Fried ESP8266 on Breadboard (10 in a row or so) –> Possibly caused by the PCB I used to connect the Wifi to my Breadboard.

If you ask what the end-goal is: Have my windows Blinds work smart depending on weather conditions and in-house conditions.

Mining Rig

After investigating crypto’s for a while I got interrested in building my own Mining Rig and test it with different Crypto’s

Components:

5x PNY Geforce 1060 6GB
2x 4GB DDR4 RAM
1x Celeron G3900
1x MSI B150 PC Mate Mainboard
1x EVGA Supernova 750 G3 Power Supply
1x Kingston 120GB SSD
5x PCIe to PCIe extension over USB3

When consuming close to 500 Watt we see the following Hash rates with ETH and PASL Together:

110 Mh/s ETH and 1108 Mh/s PASL.
Temperature is stable around 80 degrees for all 5 cards.
When going for higher HASH rates I am observing crashes.

Eventually I have sold off this rig after 2 months as this was more a Proof of Concept and the ROI was way too long for me with regular power costs (0,19 Eurocents per kWh)
