My Experience with HFMD

At the age of 45, contracting HFMD is the last thing on my mind, but that was what exactly happened on the 19th of June 2018. The week prior to my infection, I was playing tour guide and host to my relatives from my wife’s side for almost a week. They were visiting Singapore for the first time and I wanted to make sure they enjoy their experience here. After I sent them to the airport, I prepared for my own vacation. A week long trip to Taiwan with my mother, wife and 4 year old son. I have to admit that planning the logistics and hosting my relatives have left me stressed out and tired. In fact, originally I looked forward to the Taiwan trip but it turned out to be a very stressful and rushed affair for me. Coupled with lack of sleep and a sudden change in my dietary cycle ( I was doing intermittent fasting for the past 2 months), my body’s immune system was compromised.

On the first couple days in my trip I still felt fine, however on the 2nd day, my son developed an ulcer and I had to go to a local pharmacy to get medicine for him. There is a possibility I could have caught the infection from him, but he didn’t develop full blown HFMD. On the 2nd day I noticed a small blood spot on my left index finger. I squeezed it and a drop of blood came out and the pain was prickly sharp. I didn’t think much about it. That was on the 19th. Subsequently the 2nd day saw more spots appear on edges of my fingers and touching the  spots caused a sharp pain. Then small ulcers start to appear in my mouth between the gums and inner lip, these started to spread till I  even had them under my tongue.  More spots appeared under the palms and on and under my feet. Opening and closing my fingers became painful, eating became very annoying due to the ulcers. I had to use some of my son’s medication to keep the ulcers from stinging. On the 2nd day, I had to take some of my son’s fever medication to keep a fever under control. I was getting very lethargic and have very low energy levels. By the 3rd day of infection, my body couldn’t take it anymore and I had to ask the tour leader to retreat to my bedroom for rest, not before purchasing some Panadol from the Watson’s pharmacy.

By now the dots on my hands and feet had become full blown blisters bleeding internally when you pressed them and filling with angry red blood. My mouth had canker sores and they grew and joined and eating was pure torture. I kicked myself for not bringing a big bottle of Colloidal silver, something that could  at least keep the coxsackie virus under control.  On the 4th day, I recovered enough to go out for some sightseeing, shopping and night market tour, however the blisters and ulcers are still causing massive discomfort. At this point I just look forward to go home as soon as I could

On the last day of the tour, immediately after I reached home, I downed about 1 liter of Colloidal Silver. It was Saturday 23rd June when I drank the 17 ppm strength colloidal silver. I went to bed almost immediately. I spent the whole Sunday resting and drinking more colloidal silver and swishing my mouth every few hours with more CS. 24 hours after my Colloidal Silver treatment, I began to feel the pain and negative effects of the blisters and ulcers beginning to subside a little. 48 hours later, I continued to drink cups of Colloidal silver and swish my mouth with it, I began to feel the virus retreating.  Exactly 1 week after infection and with the colloidal silver protocol, the worst effects of the HFMD are gone. My blisters don’t hurt anymore and the ulcers subsided.

As I am writing this, it is exactly 2 weeks 2 days after I got infected. The blisters are gone and ugly red spots have completely subsided. For those of you who believe in the efficacy of Colloidal Silver, I highly recommend packing at least a pet bottle 1.2l of it on your overseas trip. Rather than buying ready made Colloidal Silver, I made mine using pure Distilled water and a Colloidal Silver Generator

I firmly believe that if I had my Colloidal Silver with me, I didn’t have to deal with the pain and discomfort that HFMD brings along. I guess I had it much easier than some other adults, or perhaps the strain of HFMD I got was not as horrendous other adult experiences.

Roasting my own Coffee

 

 

I started roasting my own green coffee beans this year with the belief that I will get the freshest coffee beans all the time. It was not as simple as I initially thought, but it was a great learning journey figuring out how to roast my own coffee.

I have always been a coffee drinker . I probably started drinking coffee when I was about 4 or 5 years old. The taste and aroma appealed to me right from the beginning. I learned to make sock coffee watching my mother and as I got older, I progressed into getting a coffee drip machine using packaged ground coffee. I discovered that freshly ground beans gave the best tasting cup of coffee, so I again upgraded from pre-packaged ground coffee to freshly home ground coffee. After using a small Braun coffee chopping grinder for a couple of years, I upgraded to an expensive Braun burr grinder and I swore by freshly burr ground coffee for almost a decade.  A few years back I heard that folks in the United States are using  air pop corn roasters to roast green coffee with some success. It piqued my interest in roasting my own coffee. It was hard to get green coffee beans in Singapore several years back on small amounts so I shelved the idea. Recently I discovered many sources of green coffee beans on sale and online in Singapore. I managed to get a reliable source and started my Green coffee roasting adventure.

IMG_20170911_112632

I have a 20 liter toaster oven at home, large enough to roast a large batch. I got myself a rotisserie wire basket online.

My first attempt ended with coffee that was slightly under roasted. It was okay but not great. In my research, I began to understand the different temperatures the coffee bean goes through during the roasting process.

IMG_20170917_002613

My set up was not as professional as dedicated coffee roasting machines, but through experimentation and with different coffees from Colombian, Guatamalan, Ethiopian, Indonesian Java and Sumatran Mandheling and even Burmese coffee, I developed my own roasting method. I used to monitor my temperatures closely with a temperature probe but I found the best way to monitor the roast is to look at the colour of beans as it is being roasted. Look for the smoke and especially LISTEN to the cracks. If the beans does not produce any cracking sounds, then they will be most likely under roasted; which still produces a decent cup but perhaps with a more fruity and less “toasted” taste. I like my coffee dark but not too dark so I go for a city roast plus. I have roasted coffee way pass City Roast before and after resting the coffee, they produce way too much oil. Now I try to keep it between City and City plus roast. This produces the nice balance of taste and fragrance without the oily beans clogging my SAECO All-in-one espresso machine’s burr grinder.

Here’s how I do it – IMG_20171008_153615

Coffee Cracking during roast

In the above, Indonesian Java or Mandheling coffee is being roasted and producing the 1st cracking sounds after around 25 minutes from a cold toaster oven without pre-heating. The oven is equipped with the rotating roasting wire basket with metal spoons and scoop added to agitate the beans during roasting. Maximum temperature setting was used on the toaster oven at 250C. Mechanical timer was set to 30 minutes but roast was stopped before that, probably around 25 minutes. In the past I used to pre-heat the oven, but I found it was not necessary. Aluminium foil was used to reflect heat back from the clear tempered glass door. A small hole was cut to observe the roasting colour of the coffee beans. A powerful white LED light was used to shine into the observation hole. Roasted coffee in the wire basket was removed with thick oven gloves and agitated to remove the coffee silver skin or parchment. Then beans are emptied into a large Ikea mixing steel bowl and stirred with a wire egg beater against a fan to cool down. The freshly roasted coffee beans was then stored in a single way valve container to allow the Carbon Dioxide to escape. Coffee reached maximum fragrance on the 2nd or 3rd day and ready to grind and brew.

Through this experience I now have possibly the freshest coffee I can enjoy. For those of you who live in Singapore and want to get a reliable supply of Green coffee beans, I highly recommend – Blendnew Coffee

This is the first test flight I am attempting while using the X-CAM Tech X-CAM 100B 2 axis Brushless Gimbal. The initial results are very promising. Although there were some roll jitter issues (which I smoothed out using Deshaker), overall the 100B worked very well. I was also concerned that my re-configured Reptile Quad will not be able to handle the weight, but the test flight proved that the motors, props and battery configuration can more than handle the additional weight. All that is left for me is to re-tweak the roll gimbal settings. On another note, the previous carbon fiber propellers doesn’t seem to be generating much lift, changing to carbon nylon Gemfan 11×4.7 props improved the lift efficiency. 11 inchers are about the biggest props I can use, 12 inchers will hit each other. Overall, I’m very impressed with this product.

The X100B is powered by a 850mah 3S 25C Zippy Compact LiPo.

Video Stabilization with Deshaker V3

I shot this video on my Reptile 500 Quad with my old 1st Gen GoPro Hero HD camera. There is some rolling shutter caused my extreme moves, but overall the footage is pretty alright for most parts. I’ll be testing this setup with my GoPro Hero 3 Black Edition the next weekend.

Video is post stabilized with the Deshaker V3 Filter for VirutalDub, all freeware.

I like my Reptile 500 Quad, and it flies like a dream. Having it equipped with a APM2.5 and GPS, it is almost semi autonomous. However shooting video on my GoPro on it is terrible as the vibrations caused lots of rolling shutter and resulting in jello-vision. I have tried all sorts of methods to eliminate jello but this is one method I have not tried yet, so hopefully I’ll know this weekend when I go for a test flight.

I’ve used a couple of Furniture Coasters and a Bicycle brake cable steel wire rope with brass connectors to construct this Wire Rope suspender. Hopefully it will eliminate the annoying rolling shutter effect caused by vibrations. Will try a test flight this weekend. I’ll probably pour some epoxy glue at the suspended coaster to keep the wires from sliding.

Success!!!! It works much better than I thought! This is the best way eliminate jellovision from your quadcopters!
