Tom Baker is turning his long-lost Doctor Who movie script into a novel | 25 Amp Circuit Breaker

My original quote is based on the project you called me in for. If I find out there’s actually a larger issue at hand, I’ll need to increase my price to match the scope of the project. I’m not ripping you off, I’m just making sure I get compensated for the extra work.

The device uses a triac to do the switching, and is optically isolated from mains. Be sure to check out the video after the break to see the device in action. All in all, this could be a great way to get started with home automation, or maybe just do something simple like build a timer for your floor lamp. Anything is possible!

I think that one of the statements that stuck with me the most while doing LV operations training was from a doctor who said “If you are admitted to my hospital with electrical burns then I will do my utmost to make sure that your family get here before you die”

With the large kossel build a mains heated bed is used. The mini kossel build used a reflective surface under the heated plate, a bit heath robinson, that it is used on the new larger build is good, heat is reflected up into the bed, lt worked well on the Mini Kossel.

Dunning-Kruger effect. It’s impossible to correctly estimate your own stupidity. This is the cause behind half of everything wrong in the world. The other half is psychopaths in positions of power.

I’m currently looking into buying some Class 2 insulating gloves for our hackerspace, for starters. Better safe than crisp…

I use a variety of a/c and dc fostek ssrs. I have yet to have a problem, but i use them in circuits where 50% of their rated current is the absolute maximum they will ever see.

Besides the overexposure bias, I also found the A33′s metering system was prone to more variation than I’m accustomed to seeing in an SLR. The few times I had it locked down on a tripod, shot to shot exposure seemed pretty consistent, but on several occasions shooting handheld, I found significant variation between successive shots, apparently resulting from fairly minor changes in framing. I’d of course expect exposure to vary to follow changes in the scene, but the amount of variation I saw between very similar shots taken with the A33 was unusual.

There are people that play with high voltage stuff like Tesla coils, induction heaters etc. Now those know enough to respect high voltage.

And for example the max continuous current one is “rated” for is 20A, and when I calculated the values without any heat sink, I should be able to run about 700mA. A lot of people forget to do this step before de-rating.

I’d like to know how this does around town and also on the highway (independently) when the battery is exhausted. Maybe we should get standard EPA measurements with the battery starting empty in addition to the eMPG test.

Oh, and I have fixed about 15,000 of the old CRT TV’s so while my mistakes can’t ever be called good, they’re not without precedent.
