These were really designed as controllers for printers, washing machines etc. But of course the electronics hobbyists thought it'd be great to use these to make home computers. When I first saw these things in electronic magazines I had a hard time working out what you'd actually use them for, but they seemed interesting. But most of the hobby circuits publishe… text/html 2022-10-03T12:55:55+12:00 http://projects.scorchingbay.nz/dokuwiki/electronic/equipment/h500?rev=1664754955&do=diff Overview To help train electrical engineers in digital electronics Digital Equipment Corporation (DEC) produced a digital logic trainer together with a training course. It allows students to connect up various configurations of basic logic gates following a workbook to get a hands on idea of what it was all about. text/html 2024-02-06T09:29:03+12:00 http://projects.scorchingbay.nz/dokuwiki/electronic/equipment/icl7106?rev=1707164943&do=diff Overview In the late 1970's an evaluation kit for the Intersil all in one Analog to Digital (ADC) chips with built in display drivers, ICL 7106 (LCD) and ICL 7107 (LED), was produced. These very successful chips are still produced today and are the engine of many digital multimeters. Although the boards are labeled “Intersil ICL7106 Evaluation Kit” , I'm not actually sure whether they were manufactured by Intersil. text/html 2022-09-12T07:16:09+12:00 http://projects.scorchingbay.nz/dokuwiki/electronic/equipment/mice?rev=1662923769&do=diff [Cone icon by Fornax, CC-BY-SA 3.0, wikimedia commons] Overview I've often thought that computer mice would be useful pre-made input devices for movement, and button sensors, so this is just a start to collecting information about them.

Such modifications will no doubt void any warranties on any equipment connected to it. Normally the power supply outputs are of low voltage and safe. If you don't open the power supply case you shouldn't be exposed to any dangerous voltages BUT it is entirely conceivable that by mis-wiring the outputs you may induce a fault condition that could cause a fire or produce hi… text/html 2020-04-12T06:38:53+12:00 http://projects.scorchingbay.nz/dokuwiki/electronic/equipment/rinnai551f?rev=1586630333&do=diff Overview System operation On power on the red LED should light, then within 2 seconds the combustion air compressor fan should start up. After running 15 seconds there should be the sound of the gas being turned on and the gas should be ignited and visible in the viewing window. After heating for a while the convection fans should switch on (about 40 seconds after ignition). text/html 2024-03-11T22:10:48+12:00 http://projects.scorchingbay.nz/dokuwiki/electronic/equipment/sidebar?rev=1710148248&do=diff Equipment * Calculators * Cameras * CD Roms * Faxes * FDDs * Gadgets * HDDs * Lamps * Mice * Phones * Printers * Remotes * Sensors * Timers * Tools * Videos * H-500 * ICL 7106 Kit * PS-7331-1C * Rinnai 551F * SC/MP * XY-J02 text/html 2024-03-11T22:10:14+12:00 http://projects.scorchingbay.nz/dokuwiki/electronic/equipment/start?rev=1710148214&do=diff Documenting various gadgets, machines and equipment * Calculator schematics etc. [PAGE UNDER CONSTRUCTION!] * Cameras.
