    Any Vapers Here?

    I agree, and disagree.. Tar is definitely a carcinogen as it contains benzene, acrylamide and acrylonitrile as well as, Nicotine. Nicotine, while not cancer causing on it's own is associated with heart disease, vascular narrowing and clot formation. ( significantly increases the risk of...

    Any Vapers Here?

    We have a tonne of vapers here in Victoria. Quite a few people using BHO vape pens though and in one case coming back home got exposed to secondhand smoke a few months ago. I got a second hand "cerebral high", and it was pretty strong. complete with enhanced flashing colours, audio distortions...

    What South Koreans think of North Korea

    A little update, DPRK and ROK tensions are ratched down considerably, and the DPRK is sending it's top entertainers to the Pyeongchang Olympics another sign that there is a considerable thaw in relations between DPRK and ROK. however.... nuclear disarmament is off the table when it comes to...

    Bicron Surveyor M mod - PIC scaler BIG POST

    Well, there will be some more updates on this project coming very shortly. I finally got my replacement Yocto-PMW-Rx signal board after my Rev A developed a strange issue with its flash memory. I sent it back on November 20th and received the replacement on December 27th, over a month later...

    ColdHeat Solder irons

    Good quality Pb free is usually expensive, and most commercial boards done in Pb free will fail due to mechanical stress as it tends to form a brittle crystal structure. However, * Indium Corporation's Indium5.7LT, 58Bi/42Sn eutectic alloy products look promising however and for those...

    ColdHeat Solder irons

    The only solder one should be using in a hobby or repair environment is eutectic Solder, as it has the best wetting properties, mechanical strength and melting temperature going. Eutectic solder is 63/37 Sn/Pb. 60/40 while might be cheaper, may also contain an acid core which you do not want...

    ColdHeat Solder irons

    I had one of those cold heat soldering irons when they first came onto the market. It couldn't solder anything much beyond 26ga, and what it did do made very brittle solder joints. I guess for testing sake it might be ok... but it don't expect too much. The soldering tip is made of a...

    Videos from youtube you wish to share.

    Riiight, all this while Saudi Arabia funds wahhabist Militias and exports terror to Syria, Iraq and Turkey and then to Tehran to shoot at innocent civilians. Yup, and surprise an Shia ally of Iran fires a missile towards Saudi Arabia.

    vVHnXn5Ipes The David Horowitz freedom centre is a wild pack of Zionists, and can't distinguish Iranian "govt" from its people... how Sad. I'll say it again, Iran isn't our enemy. I wonder if they'll ever make a video explaining the backlash from their own people esp. the Naturei Karta; Jews...

    Off to Thailand

    I'd be very careful going into Myanmar. Best to go by plane to Yangon with a visa from your local (Burmese Embassy). One thing to mention is if going in by land transport it is perfectly normal to expect to have your passport confiscated at the point of entry by Myanmar border guards and then...

    Radioisotopes Are Your Friends

    Yes, exactly what I am thinking about the story. I liked the story and found it especially moving seeing as I had host grandparents that lived not too far away from this fellow in Soma-shi. Soma is approximately 50Km to the North of the Futaba-region where the TEPCO power plant is located.

    Radioisotopes Are Your Friends

    A related video to the conversation about the residents of Fukushima prefecture who stayed behind to help animals. Just a vice video that I found quite refreshing on the subject Cs137 and all the other impacts people just don't think of. gs-q-2893uw On other news, I am still awaiting my...

    New Pocket Portable High Res. Spectrometer the size of a deck of cards

    Be prepared for a sticker shock. As soon as they put 5Mhz 16bit ADC, and 2049pixel CMOS sensor and 5uM grating I instantly figured +$2000. ADC's at that frequency and bit depth are at least $200 a pop.

    Bicron Surveyor M mod - PIC scaler BIG POST

    Yes, nice considering the size, but if you look at the spread here it's not nearly a fine as it could be! that large peak should be a skinny (59.54KeV) peak. CsI/Na is close to NaI/Tl in light output but it is denser. This changes the way that the Gammas interact with the Scintillation medium...

    Off to Thailand

    What you describe is a typical gas station outside battambang, Cambodia. Yup... people smoking and lighting up next to the pump and no $hits are given. Safety is a luxury option.. :thinking: This is more what is seen outside the cities in Cambodia and in very rural parts of Thailand.

    Bicron Surveyor M mod - PIC scaler BIG POST

    The PMT works like a charm and is insulated behind about 3cm worth of electrical epoxy on top of a few mils thick of 5Kv rated silicone wire. I have had it running now for about a month and it works like a gem. I am also able to use it for gamma spectroscopy and it gives " somewhat decent...

    Bicron Surveyor M mod - PIC scaler BIG POST

    Just a few updates on my Bicron Surveyor MS project, I have had to send my PMW-Rx back to the manufacturer due to what I believe might be a corrupted flash memory module or a glitch in the firmware. Yoctopuce in Geneva, Switzerland received the module I sent to them about 3weeks ago Wednesday...

    Off to Thailand

    Actually, Methanol in Alcohol is a big problem in Indonesia as well, though I didn't know it was in Thailand as well... not surprising, however. I had a friend of mine go to Bali and then to Lombok about 3.5 years ago only to discover that several British tourists he had met at a hostel...

    Off to Thailand

    Well, I'm sure you'll have lots to talk about after finishing your trip. Thailand is an adventure every day. What you see around you and on TV is some of the most memorable experiences of your life. Thai advertising is pretty different. It can be heartfelt, then the next ad totally...

    Off to Thailand

    Yup, good idea to get an international license and copy it just in case it suddenly goes missing. Having a friend who works for the Thai Govt (Police and Military) An Intl. drivers license (IDP) is an absolute must if you plan on driving/renting a car or motorbike (what constitutes a...
