In contemporary Western society, electronic devices are becoming so  ...   having any input from you about the incident on Dec.. 5th, in.. spite of repeated efforts to meet with you, I have to make a decision.. in this matter based solely on the Campus Police report.. Your "art project," a black metal box with wires protruding from it,.. was discovered by the Campus Police attached to a girder in East.. Garage in the early morning hours of December 5, 2002.. A note.. attached to it described as a Course 6 EE art project, a questionable.. claim as art is not usually associated with electrical engineering.. The Campus Police tried to contact you at the email address on the.. note but, receiving no answer, removed it from public view, to.. prevent panic by anyone who might have thought it was a bomb.. It appears that you either disregarded the likelihood that someone.. might be frightened thinking it was a bomb or you intended to cause.. that reaction.. That is not acceptable behavior at MIT.. It is.. fortunate that the Campus Police discovered and removed it before.. that could happen, but that good fortune does not exonerate you.. Accordingly, I am issuing this written warning to you.. You have a.. disciplinary record as a result of this incident for one semester.. If you have no further incidents between now and next June, then your.. record will be expunged.. I am willing to reconsider this decision if you come and talk to me.. Carol Orme-Johnson.. Assistant Dean for Student Conflict Resolution Discipline.. Director of Mediation@MIT.. Massachusetts Institute of Technology.. E32-133.. 617-258-8423.. Emphasis mine.. May 17, 2011 20:07..

O.. ne of the great frustrations of electrical engineering is part obsolescence, price and scarcity.. In accordance with engineering law, half of what's ordered is never used and the other half's not enough.. The most popular style of EE hacking that I've seen is a pack-rat approach where everyone amasses 'a few of everything', perferably for free or scavenged.. Granted, IC's are relatively cheap for their functionality, ranging from $.. 60 for a 555 to $15 for a high-speed digital signal processor, but they add up fast.. (Especially since you'll need at least 2 of everything  ...   function generator and EEPROM programmer, not to mention the wire, boards, hand tools, etc.. In these days of low-cost, all-in-one Taiwanese epoxy-boards, just finding someone who will sell you 3 of those can be a headache.. Many hobbyists, myself included, are leaning towards if you cant get it from Digikey, then I'm not going to design with it.. Regardless, there are some tricks that can make your small-scale project easier to manage.. Table of Contents.. : How to get free samples of parts from manufacturers..

  • Title: Fresh Air
    Descriptive info: Overview.. Hardware.. Fabrication.. Download.. Resources.. Fresh Air.. The Fresh Air project is a low-power, extensible RF jamming system for personal use.. It is intended for city-dwellers who feel that their personal space is being overrun with undesired radio transmissions.. The hardware is a digitally-controllable 1-2.. 5GHz voltage controlled oscillator (VCO) that can transmit on virtually all RF bands we encounter on a daily basis (PCS, RFID,  ...   batteries and be essentially disposable ($20 'retail' fabrication cost).. Intended Uses.. Much like the personal air ionizers available in catalogues, this device is for cleaning up the air around the user.. By pinning this device to a bag or jacket, the user can enjoy a radius of silence.. The device is also small enough to tape underneath classroom and office desks, or tables in libraries and restaurants..

  • Title: USB 232
    Descriptive info: USB232: A USB/Serial Adapter.. Serial ports are being phased out.. but USB microcontrollers are still hard to use, and require custom drivers.. Using a USB to serial adaptor board overcomes both of these issues, as USB ports are standard on every computer, hubs are inexpensive, and these boards use a chip that is supported by MacOS/Windows/Linux.. A Simple USB Interface for Microcontroller Projects.. A $15 board that can be reused for microcontroller projects, a painless way to add USB!.. The FT232BM is a chip made by FTDI, a european ASIC manufacturer, it  ...   you want that data to be 'understandable' to a serial peripheral, you need to levelshift it using something like the MAX232, which generates the +-12V used with serial.. This chip is ideal for simple microcontroller projects that need to talk to a computer, although serial is a slow protocol for data transfer (not much more than 10K/s).. One of the great perks of USB is that the computer provides 5V power, 100mA for USB 1.. 1 and 500mA for USB 2.. 0, so you can run your project straight off of USB..

  • Title: AEther - Embedded Ethernet Prototyping
    Descriptive info: Other Technical Projects.. Firmware.. AEther:.. Networked Microcontroller Prototyping.. history.. last edited: October 6, 2004.. (under construction as we speak!).. AEther is a lightweight but powerful prototyping board for adding network connectivity to small projects.. ARP, TCP, UDP, HTTP, DHCP and ICMP support code in AVRGCC is open sourced.. Hardware is based on the CS8900A 10baseT Ethernet chip and the Atmel Atmega32 microcontroller.. Total cost is less than $50 per board.. $30 for quantities of 10.. 2 rows of 20 pin single header allow AEther to be plugged into standard solderless breadboards.. The pinout is a full breakout of the microcontroller and matches  ...   powering the board.. AEther is a hardware system, comprising of a PCB and matching firmware.. After constructing the PCB, the firmware is loaded onto the microcontroller.. The firmware includes driving software for the CS8900a chip, as well as a simple TCP/IP stack that includes ARP handling (for low level address translation), DHCP client (for networks where the client must request an IP address), ICMP client (allows you to 'ping' the board) and an example of HTTP GET.. The design is free, the code is free*, the.. compiler.. is free.. you pay for parts, solder, and coffee.. *Under the.. MIT.. open source license..
