Technique Makes Low Cost PC-Board Shields - 02/19/04 EDN Design Idea Many pc-board assemblies require shields to reduce
susceptibility to interference from electromagnetic fields. A classic example is a radio receiver, in which the
front end usually needs high isolation from the tuning synthesizer. Historically, shields for low-volume or
low-cost applications involve trade-offs. You can't justify the cost of a custom-cast shield, and shields
machined from aluminum burn through money as fast as the end mills go dull. You can make a simple shield for just
a few dollars by using commonly available die-cast aluminum "project boxes, " such as those from Hammond
Manufacturing (www. hammondmfg. com). These boxes come in sizes from 2×2 in. to more than 7×4 in. You turn the
project box into a shield by sandwiching the pc board between the top and the bottom of the box, thus completely
enclosing the sensitive circuitry. . . . [by Steve Hageman, Windsor, CA ]
TEK 5000 modules in TM500 frame - After getting a cheap PS5010 in good shape from eBay, I needed to make it work on my TM500
mainframe. Since TM500 modules can be used on TM5000 mainframes, I thought the reverse should be also possible. I
found some references on the web and newsgroups, but no details on how to do it. . . . [Roberto Barrios EB4EQA]
Telecard reader - Attention!!! This circuit its only a reader its not programmer. You CANNOT refill, hack or
any illegal thing, the telecards. The purpose of this circuit its to understans how a microcontroller read,
serial, the telecard, to build some other. . .

Test & Development Tool for DS Interface - (Data transfer via handshake test tool) The DS protocol was designed to provide
firmware-based bidirectional host-to-slave inter processor communications for situations in which no hardware
solution is available and the host and/or the slave in incapable of tending the interface in real time. The only
specialized hardware required is two bidirectional I/O ports on each chip (alternatively two input ports and two
tri-statable output ports may be used. In other words, it provides some of the functionality of the
Two-Wire-Interface (TWI, or I2C as named by Philips) where an actual TWI is not feasible in either hardware or
firmware. . . . [From Dick Cappels' project pages]
