Last bits

The last bits are coming together, piece by piece.

Not being able to extent the meter long lead from the thermocouples I used a plastic food-container as cheap box to mount the TC boards on the backside of the testfurnace.

Last step in the software development get a graphic user interface. The furnace has a micro-controller that preforms the measurements and controls the heaters. The micro controller is connected to the mirco-computer that gives the commands and logs the operation.

Python & Tkinter

After trail and error it seems the furnace will finally get a real KWh meter. From Maxim we got two 78M6613 IC’s for free and Faber Electronics mounted them on the Adafruit breakout boards. It’s a real RMS single phase wattmeter where with a single command you get the used watt’s, precisely!

After the big Arduino one board and the mess that gave in the connection to the UEXT connector on the Olimex boards I ordered a Olimexino-nano

Prototype

After a while we got the 29th April of 2014 our prototype infrared pyrolysis furnace from the metal workshop, next will building the gas-processing and computer controlled electrical parts together.

Control software

Step by step are the pieces coming together. The Raspberry Pi was not reliably for real time operation so we added an Arduino for the critical timing communication over the I2C bus. The Arduino in combination with the ACS712 samples and calculates the total electrical power consumption of the furnace.

Assembly test-oven

Assembly of the test-oven. Nearly everything fits as planned. We’re getting closer to the first public pet-pyrolysis demonstration as an alternative for pet-cremation.

Fu Shou Yuan

Fu Shou Yuan, valued at about $1.4 billion, expects death services in China to become a $16.5 billion industry by 2017. The company said that proceeds from the stock sell-off would be used to purchase land that is suitable for clients’ eternal slumber.

Despite its huge success, the Chinese government isn’t too thrilled about Fu Shou Yuan taking up valuable real estate in heavily congested cities. Amid criticism from both state media and members of the public, who assert that some burial service providers charge exorbitant fees and disregard industry standards, the communist government has recommended cremation – even burial at sea – as more sustainable alternatives.

“Despite the government’s disapproval, many Chinese still prefer traditional burial,” wrote Bloomberg. “For them, Fu Shou Yuan offers a wide selection that includes artistic tombs designed, as the company touts on its website, ‘totally according to the customers’ interest and requirements.’ … E-commerce is booming in China, so naturally Fu Shou Yuan has an online shopping option, with customers able to choose from more than 60 different tombstones.”

Those hoping to be enshrined at one of Fu Shou Yuan’s high-class burial facilities must have banks accounts as large as those of the celebrities already resting there. A plot in Shanghai reportedly sells for more than $30,000 – and that is the basic cost of land, without burial fees, headstones, or any other cemetery swag.

On the other hand, the Chinese government has promised to pay Shanghai residents’ families approximately $330 to scatter their ashes over Hangzhou Bay. With more than 9 million deaths a year, China is expected to run out of space to bury them in as little as six years.

Calcium Silicate isolation

The calcium silicate isolation, before the final assembly start it’s wise to check if everything is made according to plan. Two pieces are the wrong size. Luckily we have got extra material to experiment with and we can easily correct the problem. The CS board is Promatec 1000L bought by Moors Ovenbouw.  http://www.moorsovenbouw.nl/

Try to fit the pieces together, we have a gap.

Burial Stress

Burials being delayed as floods create dangerous conditions at graveyards

Floods in Somerset and the Thames Valley have seen funerals put on hold as wet ground is too dangerous for gravediggers

The flood crisis is causing further anguish for bereaved families as wet ground is making burials impossible in the worst-hit areas.
Authorities say there is little they can do about weather-related funeral delays that have been described as “absolutely abnormal”. While families face the possibility of extra distress, the floods have created dangerous conditions for gravediggers.
Crematoriums have not been immune from the issue either, with one having to close for about two months due to flooding.
