Dalog - Projects

In the time we have been in business we have undertaken many types of work. Shown below are details of just a few of the projects we have undertaken. Please see the History Page for details of our Original Products

Left and below are some test fixtures which were made for testing electrical equipment.

The fixture on the left is arranged so that whilst one unit is under test the other unit is being changed for the next unit to test, reducing cycle time.

The fixture below (shown closed on the left and open on the right) was designed for a single station setup where the cycle time is quite short. The fixture is arranged so that closing the lid pushes the unit under test onto spring loaded electrical contacts, and places an infra-red transmitter and receiver on the fixture in contact with the transmitter and receiver on the unit under test.

The equipment shown here was designed to be a portable demonstration unit for electrical equipment. Two units of various types could be fittted (on the left hand area) so that comparisons could be made under live working conditions.

The equipment was designed to be fitted into a brief-case style enclosure for portability.

As this was a very low volume piece of equipment, less than 10 off, all of the components had to be hand made.

As well as the type of equipment shown above we have manufactured several pieces of microprocessor based equipment based. One of these was data logger for use at a remote inaccessible site. This equipment would measure and log a 16 bit flow value onto floppy disk every two minutes. Data was normally collected once each month, but the unit would continue, unattended, logging data for up to 14 months without loss of data. PC based analysis software was provided. The unit was also fitted with a printer as a further backup of data, and battery backup in the event of mains power failure.

At the other extreme we designed and produced (in low volume) a piece of equipment to convert the data output from a serial device into the input signals and protocol required for a IBM compatible PC PS2 mouse port. The small size of the finished item belied the amount of effort involved in the design of the unit. The protocol involved in the PS2 mouse port of the PC is quite complicated, as the PS2 mouse can respond to 16 different commands. This unit was designed entirely by us, including PCB layout and packaging.

We have been involved with computers since they first escaped from the air-conditioned room. This has involved us with various microprocessors, and the IBM compatible PC almost since its' appearance. We have quite wide range of experience with problem solving, software installation etc.

We have also been involved providing Facilities management and Mechanical and Electronic design expertise at a Fibre Optic Start-up company in Southampton .
