The Versatile Laboratory Aid (VELA) is a 4-channel data logging tool that was created as part of a joint venture by Ashley Clarke and David Binney of Leeds University and Educational Electronics. The VELA was designed to be used as a stand-alone data logger that could be used out in the field and it could then be taken back to the laboratory where it could be connected to a chart printer, oscilloscope or microcomputer for data analysis purposes.

  • The Versatile Laboratory Aid (VELA) is a 4-channel data logging tool that was created as part of a joint venture by Ashley Clarke and David Binney of Leeds University and Educational Electronics. The VELA was designed to be used as a stand-alone data logger that could be used out in the field and it could then be taken back to the laboratory where it could be connected to a chart printer, oscilloscope or microcomputer for data analysis purposes. The VELA was designed and built with the intention that it would be used in schools and Universities to monitor Physics and Chemistry experiments as it could be attached to all manner or analogue probes and sensors such as pH meters, temperature sensors, light gates, Signal generator and microphones. Each of the VELA's four channels can be independently set to record voltages in the ranges of +/-250mV, +/-2.5V and +/-25V allowing a range of different input devices to be connected simultaneously. The basic VELA carries a single 4KB EPROM (ISL1 or ISL1*) which contains the basic input and output routines that handle the keyboard input and 8-digit LED display output together with seventeen user selectable programs which range from a 4-channel digital volt meter to a random event monitor which could be used with a Geiger Counter Probe to measure and log radiation levels from a source material. In total, the VELA could record a maximum of 4096 data points either from one channel or split equally between the four channels depending on the selected monitoring program. In later versions of the VELA firmware (ISL1*), the number of data points was reduced by 7 bytes per data channel as these bytes were reserved for storing channel and program configuration data when transferring data to a microcomputer.
