Some electronic kits were assembled to make complete complex devices such as color television sets, oscilloscopes, high-end audio amplifiers, amateur radio equipment, electric organs, [2] and even computers such as the Heathkit H-8, and the LNW-80. Many of the early microprocessor computers were sold as either electronic kits or assembled and ...
1947 Heathkit ad featuring the 5-inch oscilloscope. Oscilloscope OL-1 from 1954, the company's first with a relatively small 3-inch CRT which allowed for a highly competitive price of US$ 29.50 (equivalent to $335 in 2023) for the DIY kit. [1] Heathkit is the brand name of kits and other electronic products produced and marketed by the Heath ...
These never gained much popularity because only a bare printed circuit board was made available and builders had to gather up a large number of components. [specify] In 1983, the Tucson Amateur Packet Radio (TAPR) association produced complete kits for their TNC-1 design. This was later available as the Heathkit HD-4040.
Zenith Data Systems Corporation (ZDS) was an American computer systems manufacturing company active from 1979 to 1996.It was originally a division of the Zenith Radio Company (later Zenith Electronics), after they had purchased the Heath Company and, by extension, their Heathkit line of electronic kits and kit microcomputers, from Schlumberger in October 1979.
A Heathkit amateur radio transmitter circa 1969, with external VFO. A variable frequency oscillator (VFO) in electronics is an oscillator whose frequency can be tuned (i.e., varied) over some range. [1] It is a necessary component in any tunable radio transmitter and in receivers that work by the superheterodyne principle.
A successor model, the "All-in-One" Heathkit H89, combines a Z80 processor board and a floppy disk drive into the cabinet of an Heathkit H19 terminal. This model also was sold in fully assembled form as the WH89. These were later sold by Zenith Electronics with their name on the front as the Zenith Z-89. Heathkit H8 (right) and H9 video ...
CircuitMaker is electronic design automation software for printed circuit board designs, for the hobby, hacker, and maker community. [1] [2] CircuitMaker is available as freeware, and the hardware designed with it may be used for commercial and non-commercial purposes without limitations. [3]
Two Heathkit Grid Dip Meters with a set of tuning coils. The dip meter can be used either to measure the relative power lost to a nearby circuit (in which case the amplitude shown on the meter "dips") or to measure the relative power absorbed from a nearby powered circuit (in which case, the meter amplitude peaks). In either mode of operation ...
