Sounds From The Old West

This circuit shows how far integration can be taken: IC1, a Type HT82207 from Holtek does virtually everything. Only a (small) loudspeaker and the necessary selectors need to be added. The standard 18-pin Type HT82207 is an integrated sound generator, producing sounds typical of the Old West. The various sounds are selected by S1–S6 as listed below. In the quiescent state, the circuit draws a current not exceeding 1 µA.

    S1 – bugle
    S2 – neighing
    S3 – sound of hooves
    S4 – pistol shot
    S5 – crack of a rifle
    S6 – cannon fire

The Millipede

Me and a friend are both trying to build a millipede. Because of obvious reasons, the millipede is NOT going to have 1000 feet!!! Instead, its going to have 16 pager motors as feet. It will also have 3 MicroMotors to bend towards light, and a backup sensor. FEATURES:- 16 PagerMotors as feet - 3 MicroMotors to seek light - PhotoTrophic - Obstacle avoidance - Looks Cool!!! MECHANICS:

Millipede

Millipede is divided in four segments. Each segment (except the first one) is glued to a MicroMotor turned upside-down. The motor shaft is then glued to the next segment. Each segment can rotate left/right and has 2 PagerMotors on each side. This way, the millipede should turn towards the most lighted area. Ive calculated that the waist motors should turn only 30o-45every second or so. This means that I will need the motors to be 7-15 rpm. Candidates for this job can be the Lego MicroMotor, Solarbotics GM or BabyGM (unless I can get some MU915L Escaps!!!)

Weigth was a major concern since the whole bot was impulsed by pagermotors.  The waist motors should weigth no more than 70g and the body (including electronics) is about <100g. Actually, it seems that 16 pagermotors are more than enough to move the bot!!!

ELECTRONICS:
I made up this circuit, as this is my first big BEAM creation I have no idea if it works properly. The upper 3 Ms are the Lego MicroMotors and the lower Ms should be the 16 PagerMotors. On the right, you can see the MicroMotors driver.

 
Here is the explanation:
1 This is the voltage divider. It divides voltage depending on which side is more iluminated, then, the schmitt changes the signal from a wave to a straight pulse.
2 The (usual) Nv only works when the input receives a HIGH, and that is the job of the schmitts. If the first schmitt outputs a HIGH the the lower strip of Nvs will work, the upper strip should stay calm because the second schmitt inverts the signal to a LOW. Thanks Math!!!
3 I can now be sure that there wont be 2 pulses on a same motor, and that when the first motor turns left  (or right) the next one will also turn that same way, and the next and the next.... Only the first motor is affected by light, the others follow (in a wave pattern) the one before themselves. Since the millipede is moving forward while all this happens, a nice wave should appear when the bot has locked his path towards the light source.
4 This is the backup switch. When the bot bumps into something like... Hmm....anything, the cap is discharged trough the right schmitt. The (now LOW) output of the schmitt will reverse the PagerMotors, thus, reversing the whole bot.
5 This is the PagerMotors driver. I took the 4 transistor circuit design and modified it to be used with only one input signal. I know I wont be able to drive the 16 motors with 2N390X transistors, I used them in the schematic only because I need to find more powerful ones. Probably FETs?
6 As an extra (Yupeee), when the bot reverses it also makes the spinal column think that light is fully comming only from one direction. Because of this, when the millipede reverses, it also turns to one side all the body.

Serial Voltmeter using the PIC16C71

Serial

Building a serial voltage meter to measure from 0 to 5 volts DC is actually pretty easy. Using MeLabs PicBasic, and Microsoft’s Visual Basic Version 5 Pro. You need Visual Basic Pro version because you will have to use Basic’s MSComm control. This control is not available in the Visual Basic 5 “Learning” Edition. The PIC16C71 simplifies the task even more by having a built in A/D converter. Pins 17,18,1,2 are the analog inputs AIN0,AIN1,AIN2,AIN3 respectively.

It is the place where cell phone jammers is necessary to be used

It is the place where cell phone jammers  is necessary to be used
SMS one is not more than 70 words, sent from the platform to the user to receive the fastest just ten seconds; MMS a maximum capacity of about 40K or so, they can be quantified 10 (version), a total of 3000 words plus four pictures. During the Olympics, a huge crowd working life limit, in the absence or the move, this time, the convenience of the mobile newspaper will get the highlights. The mobile newspaper reported almost the only way they always watch the game. Even those people in front of the TV or computer all day, accustomed to the phone reported as the main source of information. After all, they care so deeply about the time of the live matches through mobile newspaper. It will supply the power for cell phone jammers itself.
You can use the minimum cost of reading to grasp all the games dynamic. Some even reported as a daily spectator guide. As of 24 on August 12, more than 10 million through China Mobiles "Olympics phone" concerned about the Olympic Games process. According to the survey interview, informed students on the use of mobile phones reported during the Olympic Games through the Olympic Mobile News Olympic Alerts feel convenient fashion. Some students said that each month as long as put into the cost of a few newspapers will be able to browse the entire month of Olympic information reports, cost-effective and innovative. Advantages: "Olympics phone" to take the combination of MMS and SMS text messages to ensure the timeliness, MMS meet the depth reading. It means the open wire and concealed wire laid on the wall where the installation of  cell phone jammers will be carried out.
Early as the MMS one a day, one day a text message. July 1, 2008, increased to one day two MMS, SMS day three. Distinct content characteristics and strong technical support, Olympic mobile newspaper rapid expansion. To the Beijing Olympic Games start the first week, ordered the Olympic mobile newspaper users exceeded 10 million. The phone reportedly has a high arrival rate and circulation rate. This Olympic Games, millions of users are informed of Liu Xiang out of the race through the Olympic mobile phone SMS messages. Mobile terminal message, can be understood in a way to remind mandatory reading. Users also need to periodically delete old short color information in the phone to save memory space. It is the strong electricity around antenna of  cell phone jammers .This removal process itself can also increase the likelihood of the second reading.

The component of mobile phone jammer is separate

The component of mobile phone jammer is separate.
In Nokias share of nearly 40% behind, hidden in its mobile phone sales channels infighting. Of the Nokia mobile phone sales channels, the channel model of the mobile phone industry is broadly divided into the national agency system, the provincial agency, the manufacturers supply model, first proposed by Nokia provincial direct control of distribution of Nokia mobile phone sales channels mode. Nokia mobile agents Postel and Telling, and last year the introduction of Synnex Technology International. We can find, continuously reported in the first half of this year, Nokia channels to dissatisfaction with the low gross margin and resentment.
The omnidirectional antenna of mobile phone jammer can be provided at different price.
Nanjing Panda Mobile Communications Equipment Co., Ltd. (abbreviation PMC). This is a mobile phone sales, R & D, production, sales and technical service in one enterprise. The company has set up 20 branches in Jiangsu, Sichuan, northeast, Guangdong, Shanghai, Beijing, formed based in Jiangsu, echoing the north and south, radiation thing, the market, sales, business-linked target sales network to expand its market share and actively to expand overseas. According to the Nanjing Panda 2003, its total mobile phone sales in the first half of 2003 of 1.306 billion yuan, ranked fifth in the domestic mobile phone. However, according to latest data released in early April 2004. This mobile phone jammer system has the anti-damage protection function.
Chinese mobile phone an annual capacity of 2004 exceeded 170 million mark, while the total market capacity is only 69 million units, the middle will have to deduction of no small proportion of the mobile phone market (in Guangzhou and other places, and second, the proportion of a conservative estimate more than 20%). According to the view of modern marketing, product characteristics is a key factor in the impact of marketing decisions. So a study of the mobile marketing channel to start from the phones features and marketing features. Phone as a convenient communication tool, has its own characteristics. First of all, the phones main function is the most basic function of communication. With the development of society, an increasingly wide range of peoples activities, the concept of global village has long been popular. It can prevent the intentional and unintentional damage to mobile phone jammer .
