Second was with an old (illegal) CB amp that I was converting to HF, and I touched an unshielded feed inductor of some sort, the aftermath from the RF burn was worse than that time I grabbed the wrong end of an iron with my fingers.

MLVs come in various chip form sizes, and are capable of dissipating significant surge energy for their size. Thus, they suit both data-line and power-supply transient-suppression applications.

Still, the orderly May backdrop registers as bullish, versus the prior three months, punctuated by the S&P 500’s flag pattern pinned to the steep early-month rally.

The Sony A33 uses the image sensor itself when metering, and considers the overall image as 1,200 separate zones in performing metering calculations. Metering modes include Multi-segment, Center-weighted, and Spot, and the metering system can function from -2 EV to +17 EV (at ISO 100 equivalent with an F1.4 lens). An autoexposure lock button is provided, allowing metering to be locked from a specific portion of the subject, then the overall image reframed as desired. +/-2.0 EV of exposure compensation is available, in 1/3 EV steps. The A33 also offers a three-frame exposure bracketing function, which allows a step size of either 1/3 or 2/3 EV between subsequent frames. Shutter speeds from 1/4,000 to 30 seconds are available, as well as a bulb position that holds the shutter open for as long as the shutter release is pressed. Flash X-sync is at 1/160 second. White balance options include auto, six presets (Daylight, Shade, Cloudy, Incandescent, Fluorescent, and Flash), plus both custom and direct color temperature (2,500 to 9,900K) options. The six presets allow +/- 3 step adjustment, and there’s also a color filter setting that provides +/-9 steps of magenta / green compensation.

One of Sony’s nifty tricks is their in-camera "sweep panorama" technology. The A33 and A55 let you shoot panoramas with the camera held either vertically or horizontally. The vertical orientation makes taller/narrower panoramas that are 5,536 x 2,160 pixels, as seen in the top photo above. With the camera held in landscape orientation, panoramas are 8,192 x 1,856 pixels.

So it’s the usual forgettable Toyota – but still hugely preferable to the godawful Prius which is a truly horrendous looking vehicle 

Very nice hack and well documented, safety issues included. For all the rest of the naysayers, you are far more likely to die driving your electric car than from a charger failure yet most people think nothing of jumping in the car despite it being one of the leading causes of death in the US.

So here follows the first in a series on how to approach electronic devices containing high voltages, and live to tell the tale. By “high voltages” we mean anything up to mains voltages, and those directly derived from them such as the few hundred volts rectified DC you’ll find in a switch-mode PSU. For multi-kilovolt EHT you’ll have to wait for another article, because that is an entire subject in itself. We’ll mention these higher voltages in passing, but their detail is best left for a Hackaday colleague with more pertinent experience.

We recently had a chat among the Hackaday writers about how we could approach this subject. The easy way out is to be all Elf-and-Safety and join the radioactive anthrax crowd. But the conclusion we came to was that this site is a resource for hackers and makers. Some of you are going to lift the lid on boxes containing significant voltages no matter what, so we thought we’d help you do it safely rather than just listen for the distant screams.
