This is only a preview of the March issue of Silicon Chip.
You can view 36 of the pages in the full issue and the advertisments. March - Silicon Chip Online. Articles in this series: Reach For The Sky.
And Way, Way Beyond, Pt. Built-in safeguards include temperature sensing of the cells to prevent overcharging. Kit supplied with double sided, solder-masked and screen-printed PCB, die-cast case x 94 x mm , label and electronic components.
Substitute different regulators to those supplied and you can alter the output voltage to your requirements. Designed for use with 40W to W 12V solar panels and lead acid batteries, this solar charge controller kit provides 3-stage charging with the option of equalisation and with MPPT Maximum Power Point Tracking.
Operation is for 12V panels and batteries, but a 24V upgrade will be available in future. Using low cost, high capacity rechargeable cells, the kit will pay for itself in no-time! You can use any 1. Imagine the extra capacity you would have using two mAh D cells in replacement of a low capacity 9V cell. Kit includes PCB, and all electronic components. Suitable for use with cordless power tools, emergency lights, small to medium UPS up to about VA and a wide variety of other devices.
This handy voltage regulator can provide up to 1,mA at any voltage from 1.
Ideal for experimental projects or as a mini bench power supply. Kit supplied with PCB and all electronic components. Depending on the input voltage and the heatsink you use, it can deliver an output current of up to 4 amps or so.
Literately any kit you see on these pages that uses an LED as a trip-condition indicator, can be used with this nifty project. Use the relay to sound buzzers, switch on lights, operate solenoids, trigger alarms, etc. It has an isolated input, and is suitable for a variety of triggering options, including an AC or oscillating signal. It also has a relay-on LED indicator. Kit includes PCB with overlay and all electronic components. Are better output transformers, more expensive valves and so on worth using in the Currawong Stereo Valve Amplifier?
Now we get to the good bit.

Phone 02 Fax 02 This is an option being looked at longingly by many electricity consumers as they are confronted by ever-higher quarterly bills and if they have solar panels on their roof, the prospect of diminishing solar feed-in tariffs as time goes on.
What might have looked like a sure-fire investment just a few years ago, now looks somewhat diminished as various state governments have realised the threat to their budgets if they continued paying the originally generous solar feed-in tariffs to those in the vanguard of solar roof-top installations.
Furthermore, as more and more solar panels have been installed, it has become common in some areas for the mains voltage on hot sunny days to run up against the VAC or thereabouts threshold voltage of most grid-tied inverters and so they are throttled back to the point where they may generate very little or no power.
Finally, how many people with solar panels on their roof are severely frustrated when a blackout occurs? To me, that must seem like a serious injustice. Alas, that is not so. Trouble is, there are no easy options.

For a start, you need a new inverter without the anti-islanding feature. Second, you probably need a lot more panels because most roof installations only have a capacity of a few kilowatts. Of course, if something in your off-grid power system fails, you cannot simply phone your friendly not so mercenary, perhaps? And since so much of the power will be based on solar panels, storage in the form of batteries will be part of the deal.

All of this is predicted to become viable quite soon because of the steadily reducing cost of lithium-based batteries. Developments in battery technology are following a similar path to the development of flat-screen TV sets. Except that in the case of batteries, progress has been arguably slower.
In fact, a century from now people might look back and wonder about all the effort to research batteries which ultimately was futile and unnecessary because of the historic break-through in fusion power generation?

Of course, the regulators apply a whole spectrum of compliance standards to ensure safe and reliable operation. However, what is not clear is whether there is any mandated requirement for EMI-proofing the actual electronic key itself. Has anyone looked into this? After the reported spate of incidents, I bet they will be now. The answer given is completely wrong. Other devices that develop amazingly high torques or forces include hammer drills, jack hammers and simple devices such as a hammer hammering in a nail, an axe chopping wood and a pile driver hammering in a pile.

Apparently, there was a nearby US military test facility where it was surmised that they had been conducting tests of EM pulse weapons. Needless to say, the US army would neither confirm nor deny.
I wonder how many drivers casually throw their keys on the kitchen counter in front of the microwave oven! For a parallel perspective on this, reread G.
Is he blind to the dramatic developments that have recently emerged on the EV battery research scene? So sensational are the performance claims made for this battery that, if proven, it will completely transform the landscape for the inexorable penetration into mainstream use. The mass then impacts the object being driven and is slowed down in a very much shorter time. This results in a much larger force or torque being applied to the object being driven. Taking a hammer as an example, use a medium hammer blow to push a nail into a piece of wood.

Now try to simply push the nail in with a steady force. This will give some idea of the force the hammer head applied to the nail as it was being brought to rest.
Consequently, the conclusions of the ID-TechEx report are wrong which inevitably means that hybrids, as a class, will get squeezed out. Google search under Power Japan Plus, double carbon battery for more information.
Andre Rousseau, Papakura, NZ. Comment: over the decades there have been many forecasts of breakthroughs in new battery technology. While lithium batteries of various types are a big step forward compared to other rechargeables, we have quite a long way to go.
Perhaps the double-carbon electrode battery will be all that is promised. We will wait until it is commercially available. This strikes the output section, the impact rapidly slows the driver mass and supplies the large force torque.
So the maximum output torque will be about 50 times the average input torque. Please do not stop writing your editorials or tone them down in any way as then the rabid ones win and we all lose. Besides that I love seeing the pounding the Publisher gets in the Mailbag pages in the following months. It helps to make up for the pounding I got from him over my grammar and spelling errors back in the old days when writing my articles on Radio Control.
This will be a disaster for the wildlife if it happens. Attempts to catch them with a food-loaded trap are not working. Foxes like a live target.

I have had success catching them with sound. They get very excited if they hear another fox in their territory or the sound of an injured rabbit. I would like someone who has an interest in saving wildlife and has the necessary skill to design a device that makes the necessary sounds at preset intervals.
This device would have to be reasonably hifi and go up to about 30kHz but not high-powered which were released from balloons at North Head, Sydney. These were no ordinary model gliders. They were all aluminium from memory and shaped very much like a small German V1 buzz-bomb and I was fascinated by them.
They stored atmospheric data from the high-altitude balloon flights and were released from the balloon and guided back to North Head under radio control. Bob Young, Ex Silvertone Electronics. The device would be waterproof and robust enough to take a nip from a fox.
