A Short Guide to Vintage Traynor Amps | Lrd12 Overload Relay

On the Sony A33 and A55, the EVF can serve as both shooting and playback display. As mentioned earlier, the ability to check your shots and make camera settings without taking your eye from the eyepiece leads to a slightly different and more efficient shooting style; one that encourages you to learn the camera by feel and memory, rather than looking at the controls as you press them. I’ve only had a few days with the camera as of this writing, but can see that greater familiarity will produce a very efficient shooting style.

Several hot features were brought over from Sony’s NEX and Cyber-shot digital cameras, including Sweep Panorama, 3D Sweep Panorama, Auto High-Dynamic Range, and Handheld Twilight modes, each of which strategically combine and align several images into one seamless shot. It’s pretty impressive stuff. As if that weren’t enough, Sony has added an extra mode for the SLT-series cameras — Multi-Frame NR — which operates similarly to the handheld twilight mode, but allows the ISO sensitivity to be specified.

This. An isolation transformer can be a very useful thing, but also very dangerous. If you touch ONE end no problem, but if you touch both ends you will get cooked and the RCD will NOT trip. Or more directly: An isolation transformer does NOT allow you to switch off your brain! And NEVER connect a scope to such a transformer.

Three electrocutions? Better be careful cat, you only have six more left before you will die for real Receiving an electrical shock isn’t an electrocution.

Getting reasonably priced SSRs that are trustworthy seems almost impossible. A 40A TRIAC costs $34. I know there’s more than the TRIAC in the SSR, but it’s not like there are that many components either… I end up using relays if at all reasonable and scratch my head when they’re not…

The place to start when talking about mains-voltage equipment is your bench. We realise you’ll probably be working at your kitchen table or wherever you happen to be, but it’s best to start an article like this with a baseline, of what you really should have when doing this stuff. There are three things we’d consider essential in the mains power system on a mains-voltage bench. An isolation transformer to power the item you are working on if it needs a mains supply, a residual current circuit breaker for the rest of your mains supplies, and an emergency isolation switch for all bench power.

Low current (and damage-reducing high-frequency skin effect) on the Tesla coil’s HV secondary. Mains frequency penetration, arcability and cross-heart lethal current on the neon sign transformer’s secondary. So, it’s good that my wakeup call went in & out of the same arm.

The time-multiplexed full-color RGB pixel technology generally worked well to deliver very high resolution with no gaps at all between the pixels. The only place I was aware of the EVF pixels were in diagonal strokes of letters on the various VF info readouts, or on the electronic level display, when the indicator lines were tilted. I never saw pixel jaggies when looking at the subjects I was shooting, even in the case of sharp high-contrast edges.

Video capture is an area where the Sony A33′s translucent mirror technology makes a huge difference relative to pretty any other SLR currently on the market, and relative to even fast-focusing SLDs. Every other interchangeable-lens camera currently on the market either doesn’t autofocus at all when recording videos, or has to resort to slower and/or more obtrusive contrast-detect focusing. Because the Sony A33′s phase-detect AF system is always looking at the subject, fast autofocus during video recording is no problem.

Wrong again – The VOLT from the very first had a choice of 8 or 12 – it just wasn’t from the touch screen in the car in the first 2 years, it was a button on their ‘charger cord’. And there was no ‘default’. Unlike later cars such as my ELR and BOLT that must be constantly changed to 12 amps on L1 (yes, I know about zip code based charging on the bolt), my 2011 VOLT would stay at the setting you left it at since it was stored in the EVSE, NOT the car.

I’ve also experienced very similar shocks, mains flowing from one hand to another by trusting my co-worker. I couldn’t move my arms and upper body, couldn’t scream, breathe or even see during the shock. I don’t know how long it lasted and there was nobody nearby. Luckily my brain and lower body was still partially functional and I somehow managed to kick the wall in front of the, to disconnect myself from live connections. Some of my fingertips were smoking. I learned my lesson as well – never trust anyone, especially if they are repeatedly assures you that the power is down.

It’s neither a sports car nor a hot hatch — it’s just a tall hatchback masquerading as a crossover. It handles a bit better than most commuter appliances, due to the 258 pound battery mounted low in the chassis. Imagine strapping me, Keanu-under-the-bus-in-Speed style, to the undercarriage of a car. That would let the car hug the road a bit more (and seriously wound your favorite bearded auto writer, so let’s keep this hypothetical).
