You can, but it will likely not be very useful. The losses in the two transformers will be such that you won’t be able to draw much current from it and most appliances won’t work.

Finally, only consider charging units that have been tested and certified for safety by an independent source like Underwriters Laboratory (UL). And if you’re having a charger installed outdoors, make sure it’s rated for that purpose.

Note: Not all certifying agents offer online lookup, and some have a lag time for posting new certificates. If you are unable to find a certificate online, contact the certification agency or supplier for further verification.

The LCD improvement I found most the most dramatically useful was the brightness settings. Set to Auto brightness, the camera will brighten or dim the LCD display in response to ambient light. This helps a good bit in bright daylight, but the display still washes out in direct sunlight. If you’re shooting in bright sun, though, check out the Sony A33′s "Sunny Weather" LCD brightness setting. Wow – That’s a really bright display! It does blow out the top end of the display’s tone curve (that is, you won’t see any detail in the highlights in your images in this mode), but this is the first time I can honestly say that I had no trouble viewing a camera’s LCD screen in direct sunlight. It’s a really great feature, although I’m sure it further reduces the Sony A33′s already-short battery life.

• A 24-V dc circuit • Current waveform for surge is 8 × 20 μs; voltage waveform is 1.2 × 50 μs (these are typical industry-standard waveforms) • Peak current during the surge = 1000 A • The MOV must be able to survive 40 surges • Other circuit components (control IC, etc.) must be rated to withstand 300 V maximum

I think a lot of the negativity is par for the course on Hackaday when dealing with HV (or other areas with safety concerns) projects. I got my share of the same thing with my “Quick 220 clone” project. Such projects should garner a healthy dose of paranoia, but I think where it goes wrong is when that converts into unfriendly skepticism – that somehow it’s impossible for an amateur working alone to build something that would pass muster with UL or CE.

A 25A relay seems perfect for a 22A load. If the relay is really built for 25A and not only marked as one. What use had a maximum rating when you could never really use it?

Since GM was having troubles with said DOPES regarding the 2011 VOLT, they quickly redesigned the current and all future units to have an AWG #14 connector cord, while keeping the AWG #16 connector cord to the car – why? – so that the oversized connector cord would extract heat from any overheating defective receptacle.

This dead-screen issue was so pronounced that I found myself dropping back to 6 fps rather than 10 on the A55, and shooting in short bursts at what I thought (hoped?) were the decisive moments. More than with many cameras with lesser speed or buffer capacity, I found myself shooting to manage the camera’s buffer, more than simply focusing on the subject and the action taking place. It would have been a lot less aggravating if I could have at least seen thumbnails of just-captured shots immediately after taking them.

Potential starting relays consist of a high resistance coil and a set of normally closed contacts. The coil is wired between terminals 2 and 5, with the contacts between terminals 1 and 2.
