Danalog Custom Electronics Main Page

Danalog is a custom electronics business based in Sydney, Australia, offering a broad range of worldwide services, products and engineering solutions.
Our quality and turnaround times are what our customers value the most. When something is urgent to you, it is urgent to us. Our customers range from a single-person importer to large international companies, from government departments to defence forces.
Because we appreciate your time, and because many of our happiest clients come to us from nontechnical areas, we've tried to keep this web-site concise and easy to understand to people from all walks of life.

Customers often approach us with nothing but an idea and the desire to see the idea materialise. After careful examination and feasibility discussions, the idea gets shaped into specifications, is reexamined, and a draft solution may be presented to the client, including alternatives. It is then up to Danalog to produce and deliver the final product to the customer door, lock-stock-and-barrel, just turn the key.

.

Prototyping is a service we offer to customers who just need a prototype. You may already have a complete design and all you want from Danalog is one working sample. The actual manufacturing, or further redesign, may later be carried out by you, by Danalog, or by a third party. The choice is yours.

.

Most electronic equipment has to comply with some regulations, such as those concerning safety, interference, telephone line standards and others. Many appliances are imported or exported, and may need to be custom modified to suit the destination market's regulations. This can be done at the time of manufacture, but more often than not, this is left to the importer - also more often than not, an importer may finish up with a product in the warehouse that can not be sold because it contravenes one or more regulations. Danalog can help you by modifying the product to compliance level, whether it'd be a series of 10 or 10 thousands.

.

Frequently a customer may already have some electronic equipment on hand (whether it'd be an assembly line robot or an answering machine) which complies with all regulations but needs to be electronically modified to change its functionality. This could be as simple as adding an extra digit to a display, providing extra interface, disabling some functions …you name it … we'll do it.

.

In manufacturing, many a product must be tested before it leaves for the consumer. This could be a simple Pass/Fail test, or a complex functional test. Not all products lend themselves to fully automated processes (ie. no human involvement, the machine handles and tests the product by itself) and may require personal handling. But even then, part of the test may still be automated, whether it'd be a hand held battery-powered cable continuity tester, or a desktop size multifunctional analyser. Danalog has had the opportunity to help several manufacturers automate their tests (one for as little as couple of hundred dollars - yet it saved thousand times more in time, increased throughput and eliminating production bottlenecks). Simplicity and effectiveness are always paramount design criteria, and while a tester itself may incorporate a microprocessor, the user shouldn't need an Engineering diploma to operate it.

.

The line between custom design and manufacturing, or production, becomes somewhat obscure when we start talking thousands of units. But five thousand hand held widgets is not the same as five thousand satellites, so the size and complexity has something to do with the definition of 'custom'. However, regardless of definitions, whether you need one prototype 'black-box' of five thousand blue widgets with flashing lights, we will look at your requirement and find a solution. Let us.

.

Digital electronics seems to be what is running the world today. And frankly, it just about does. Many designers have jumped on the bandwagon and specialised in digital circuitry to cash in on it. That would also be fine, had they not forgotten about analog circuits, which frequently go hand in hand with digital. Unfortunately, this phenomenon has produced an army of 'digitally' minded designers and an acute shortage of those who can design even a simple analog circuit (just ask many a digitally minded designer knows how a non-negative feedback amplifier works, or how to design a simple speaker crossover). This often results in you caught between, having to split your assignment in two, find someone who do the digital part of the deal, and someone else who can do the analog rest (provided you know where to draw the split). And even if the designers do manage to get along, you still finish up with two hybrid circuits married into one; unfortunately, when something doesn't later work, you may be caught between two parties pointing their fingers at one another, no one admitting their responsibility. Danalog has the knowledge and experience of both digital and analog circuits. To you, it means single-point contact, more reliable circuits, faster turnaround, and generally much lower cost.

.

Although the overuse of microprocessors has been mentioned earlier, there are many applications when a single chip (microprocessor) with a bit of custom code can replace many components, simplify the entire design, and generally reduce its cost to you. Based on merit for each application, Danalog has built many of its products around a microprocessor. If all you need is a preprogrammed processor without any associated hardware, we can also help you.

.

A printed circuit board is probably the only denominator common to all electronic equipment. Its function is very simple - it provides all the necessary electrical links between individual components. The design of a PCB is a relatively straightforward process, especially with the software Danalog has at its disposal, but some important rules have to be followed - and these come from experience. Unfortunately, even a badly designed PCB may work to some extent, or only under certain condition, and its shortcomings may become apparent long after the designer and the customer parted. Danalog has both the experience and equipment to design single or multi layer PCBs. Because it is all done on a computer, we frequently don't even get to see the client, because they could be on the other side of the world (well, in Australia, just about everybody fits into this category :) )

.

As part of our turnkey solutions, we often must supply a suitable housing/enclosure (box) for a project. This could be a relatively straightforward punched metal box, or a more complicated combination of metal, Perspex and other materials, usually in a powdercoat or anodised finish. Custom enclosures can be designed and ordered separately, and our turnaround time, depending on complexity, can be as little as 48 hours.

.

Most consumer electronics products today are cheaper to replace than to repair. However, there are still instances when a repair is the only way. We could be talking about thousands of 'black-boxes' sold to public through a retailer with a two-year manufacturer's warranty, where the manufacturer ceased to exist before the warranty expired, and the retailer became responsible for the warranties … or the computerised production line hurling out thousands of widgets an hour till the day it went bust, just like its service company did six months before then. Admittedly, these are usually the most challenging times for both the customer and for Danalog, and a lot of time and effort is usually required at a relatively short notice. If you feel we could meet these challenges together, let's do it.
