Resident Evil 2 Remake releases January 25th: watch the first trailer | 25 Amp Circuit Breaker

CARLO GAVAZZI is proud to announce the launch of the newest addition to its RGC Series Solid State Contactor platform. These single-phase zero-crossing relays, featuring an integral heat sink, offer the best in the class current rating of up to 37AAC at 40°C or 43AAC at 25°C.

Still, most capitalists, when you order something, don’t ask “what do you want it for?”, so they can substitute something else without telling you. Generally in contracting with capitalists, mysterious “problems” don’t regularly as clockwork pop up, increasing the cost above what was agreed.

Handheld Twilight is a scene mode on the Sony A33 and A55, so it doesn’t offer you much control: The camera picks the ISO setting, shutter speed, etc, that it thinks is best, and takes the picture. About all you can control is whether to enable face detection AF or not. For those wanting the multi-shot advantages but with more creative control, Sony offers Multi-Frame Noise Reduction mode. This mode lets you select the ISO you want to use, but the camera micro-aligns and averages together six shots, significantly reducing ISO noise. You get the same basic capability as in Handheld Twilight mode, but retain full control over other exposure parameters.

I’ve had 240v shocks about half-a-dozen times, but the two that I recall were both back in the 80s, and were a) trying to fix a set of disco rope lights whilst they were intermittently working, and b) replacing the panel fuse in my CB PSU that I’d removed and hidden to stop my sister using my rig. Both of them involved my subsequent launching of the equipment across the room, accompanied by some suitable profanities.

The only way, AFAIK, to know how much current it is actually supposed to be capable of is to calculate it based on the listed thermal resistance from junction to case, the thermal resistance of your heat sink from case to ambient, and the Rds(on).

This is great info. In the next instalments I would love to see advice in dealing with a mains power supply and possibly a power line carrier modem on the same board or enclosure as low voltage components.

Opto-isolated TRIAC is fine and dandy, but there is no fuse, so if you overload it, you have a cooking TRIAC in your junction box …

The issue is we are more than willing to make unknown compromises for price. And we don’t just make these compromises with electronic components. We make the same compromises in the vehicles we drive, the foods we eat, the houses we buy…..

Exposure. The Sony A33 offers a selection of exposure modes commonplace on any DSLR, as well as several more unusual modes. These include Auto, Auto+ (Advanced Auto), Programmed AE, Aperture Priority, Shutter-speed Priority, Manual, Continuous Advance Priority AE, Sweep Panorama, Scene, and Flash Off modes. The Advanced Auto mode acts much like a regular Auto mode, taking control of most settings, but differs from the standard Auto mode in that it can also access some of Sony’s more unique multi-shot modes, such as Handheld Twilight and High Dynamic Range. Continuous Advance Priority AE increases the maximum burst shooting speed as compared to the standard Continuous Advance modes, but does so by requiring the aperture be fixed near its open position. The Sweep Panorama mode can function in either 2D or 3D variants, and allows capture and in-camera stitching of multi-shot panoramic images by simply pressing the shutter button and sweeping the camera across the subject. A selection of user-friendly scene modes accessed through the Scene position include Portrait, Sports Action, Macro, Landscape, Sunset, Night view, Hand-held Twilight, and Night Portrait, and let beginners get the look they’re aiming for, without needing to understand the subtleties of shutter speeds, apertures, and the like.

Actually most power panels I have worked on alternate phases as you go down the opposite rows, not one phase on each side, 240 breakers take up 2 breaker spaces on one side of the panel using alternate legs.

Dust reduction. The Sony A33 has a dust abatement and removal system. A charge-protection coating on the low-pass filter aims to prevent dust adhering in the first place. The sensor shift mechanism used to provide SteadyShot image stabilization also doubles as a shake mechanism to try and free stubborn dust particles that settle on the low-pass filter, although at much lower frequencies than the vibration induced by cameras using a piezoelectric element. From what we can tell, there is no strategy for keeping dust off the translucent mirror, except to blow the surface gently with air; it cannot be cleaned, and should never be touched. A fingerprint would require replacement at a service center.
