The term "homebuilt" or alternately, "homebrew", refers to the hobby of building electronics at home, generally with a soldering iron or wire wrap. No knowledge or experience is required for posting to this group. Postings may deal with real hardware, or absract concepts, and are not restricted to any specific cpu or architecture. Topics may also include homebuilt peripherals added to existing off the shelf systems, or hardware hacks to existing systems/accessories. Please note: Unfortunately, the term "homebuilt" causes a great deal of confusion amongst IBM clone builders, which leads to a large number of inappropriate posts on this newsgroup. This group, as a general rule, is not for discussion of IBM related hardware, unless there is some aspect of home built electronics involved, such as connecting your own device to an IBM serial/parallel/game port, etc. or using IBM clone hardware as part of a homebuilt design (non-IBM design). Common IBM clone hardware hacks, such as overclocking and changing the UART chip, are best discussed in one of the IBM related newsgroups. An IBM clone hardware questions pointer is posted frequently on news.answers, and due to its length the information within it will not be repeated here. Warning: Any post that may be considered an "alt.fix.my.pc" post is likely to draw flames or intentionally misleading advice from the regulars at a.c.h.h. Following such advice for a "fix my PC" type post may be damaging to your computer. You have been warned. 1.2 How to Deal With the Cancelbot Because of excessive noise (mostly involving off topic "fix my PC" type questions) a cancelbot has been set up on this newsgroup. Failing to inform the cancelbot that you have read the posting rules may result in your post being automatically cancelled. To let the cancelbot know that you are aware of the posting rules, you must add the letters "PRR" (without the quotes) somewhere in your first post. PRR stands for "Posting Rules Read". These letters do not need to be included on subsequent posts. Questions or comments about the cancelbot should be directed to achhbot@mmc.et.tudelft.nl. 1.3 Who is "PRR"? See the previous section. Some people mistakenly add PRR to every post (only your first new thread needs these letters). Some people have mistaken it for a signature. Because the letters may be included anywhere in the post, some people have taken to creative uses of the letters, which include the fabrication of information about a mythical person with the initials PRR. At the time of this writing, PRR has been in the hospital, and is known to have an affection for Milk Duds. New readers are free to contribute to this on-going "story". 2.0 Questions Answers to specific questions are included in this section. Many of the answers are only pointers to more information, so that large volumes of information are not duplicated unnecessarily. 2.1 Can I post ads on the newsgroup? As a general rule, alt.comp.hardware.homebuilt is not a forsale group and thus does not allow advertising. An exception is made for advertising that is directed specifically for electronics homebuilders, and is not otherwise available on the net in general. Examples of this are device programmers and electronics parts. Trading between homebuilders is encouraged. Items that fit well into other existing forsale newsgroups should not be advertised here. PC related advertising, such as hard drives, motherboards, and other standard PC clone parts, is not permitted. While CPU advertisements in general are permitted, CPU advertisements for the common PC clone CPU's (such as 486 and Pentium chips) are not permitted because of the existing PC clone forsale groups that already provide plenty of coverage for these parts. 2.2 Can I post questions involving hardware problems? This question was asked to the group in general, and the overwhelming response was NO! The only exception would be if you are having a hardware problem with your homebuilt hardware, not pre-fab hardware. As Andrew noted in an early version of the FAQ: "Since EVERY SINGLE ONE of the replies I got re: the FAQ said "no, this is not the appropriate place for questiongs about PC building and pre-made parts and compatibility between them, the answer obviously is a very strong NO. This is not to say that you should not post questions, but only post questions about homebuilt computers, not computers built from pre-made parts. The difference should be very clear. If you post here about your hard drive that you want to slave, i doubt if people will have much mercy. It is getting on peoples nerves." Replies to PC hardware problems are also strongly discouraged. Such replies should either be posted on the appropriate groups or should be done via private e-mail. 2.3 What's this about a new homebuilt newsgroup? It has been suggested at times (often sarcastically) that a new newsgroup should be made up with some name other than alt.comp.hardware.homebuilt, so that the group would not be plagued with off topic pc-clone related posts. A newsgroup specifically for "homebuilding" in the PC clone sense of the word (alt.comp.hardware.pc-homebuilt) has been created. All PC questions should go to that newsgroup. alt.comp.hardware.homedesigned was created in an attempt to provide a low noise alternative to this group. It has since been abandoned. 2.4 What is a "Wally" (and other terms specific to this newsgroup) * A/D - Analog to Digital (converter) * ACHH - Alt.comp.hardware.homebuilt * a.c.h.pc-h. - alt.comp.hardware.pc-homebuilt * ACK - Acknowledge * ALU - Arithmetic Logic Unit * ASIC - Application Specific Integrated Circuit * ATA - AT Attachment (aka IDE) * Basic Stamp - a processor that is programmed using Basic, manufactured by Parallax. * BCD - Binary Coded Decimal * BIT - Binary Digit * BJT - Bipolar Junction Transistor * Bug - [1] A hardware or software error [2] An Integrated Circuit (the black plastic and silver "legs" look a little like an insect) * CAD - Computer Aided Design * CAE - Computer Aided Engineering * CCD - Charge Coupled Device * CISC - Complex Instruction Set Computer * CLK - A common abbreviation for clock (signal). * CMOS - Complimentary Metal Oxide Semiconductor * CRT - Cathode Ray Tube * D/A - Digital to Analog (converter) * Dead Bug - Non-functioning IC chip * DEBUG - Remove errors from hardware or software * DED - Dark Emitting Diode (a burnt out LED) * DIP - Dual Inline Package * DMA - Direct Memory Acccess * DRAM - Dynamic Random Access Memory * DSP - Digital Signal Processor * (E)EPROM - (Electrically) Erasable Programmable Read Only Memory * EISA - Extended Industry Standard Architecture * EPLD - Electronically Programmable Logic Device * ESD - Electro-Static Discharge * FD, FDD - Floppy Disk Drive * FDC - Floppy Disk Controller * FET - Field Effect Transistor * FP - [1] Floating Point [2] Flat Pack * FPGA - Field Programmable Gate Array * .h - An abbreviation for alt.comp.hardware.homebuilt generally used in conjunction with .pc-h * FPU - Floating Point Unit * GAL - Generic Array Logic * GaAs - Gallium Arsenide * GND - Ground (signal return). * GPIB - General Purpose Interface Bus * HD, HDD - Hard Disk Drive * HDC - Hard Disk Controller * HDLC - High level Data Link Control (ISO standard) * Homebrew - referes to the art of designing and building electronics at home, and has nothing at all to do with alcohol (usually). * IC - Integrated Circuit * IDE - [1] Integrated Drive Electronics [2] Integrated Developement Environment * IIC, I2C, I(squared)C - often written as such since a superscript 2 (meaning squared) cannot be displayed on an ASCII terminal. * I/O - Input/Output * IRQ - Interrupt Request * ISA - [1] Industry Standard Architecture [2] Instrument Society of America * ISO - International Standards Organization * JFET - Junction Field Effect Transistor * KBD - Keyboard * LCD - Liquid Crystal Display * LED - Light Emitting Diode * LSI - Large Scale Integration * Midnight Engineering - refers to designing and building devices at home.

There are several methods available. Most involve etching, where a mask is drawn or transferred onto copper clad board, and the board is immersed or sprayed by an etching solution. Boards and etchant can be purchased at most electronics hobby stores, and various manufacturers products are available via mail order. Some methods use iron-on transfers, and others use a photo-etching process. There is even a method using conductive ink and laser printers. Some people have reported good results using Vector wire and Verowire (UK). These methods are more similar to wire wrapping than PCB fabrication.

Some of the software packages are designed to allow the user to enter a schematic, test the circuit, and provide an output that can then be used to directly fabricate the PCB (either an electronic format or an actual printout that can be used for etching). 2.13 What is the Net Station? The Net Station was a project whose goal was to create a computer architecture and operating system that would be freely distributed on the net. An agreement on the architecture, etc. was never reached, and the project seems to have been abandoned. The thread does see occasional revival, but little practical progress has been reported lately (to the group, at least). There are unconfirmed reports that the project is still being worked on, but details are presently unavailable. 2.14 How do I homebrew an LCD controller?
