Hello there

I'm planning to make my final project to take the degree in electronics. I would like to give me some interesting ideas for building something not too hard. It’s a little general speaking but just throw ideas, I’m in the status of collecting

Regards Kostas

That is an awfully big order. What are YOUR interests?

Do you like things that are electro-mechanical (motion control, robotics, etc)?
Signal processing?
Communications (transmission media, protocols, etc)?
Hardware interfaces?
Micropower?
User I/O?
Something else?

I like monitoring applications, everything that has to do with sensors. Robotics isn’t a bad idea, PWM to control high current components.

I was also thinking of building a controller/monitor the freezing of a PC with cascade /phase change / TEC

You can take an idea if you don’t know what this stuff are from here

http://www.thelab.gr/forumdispla...

It’s Greek but there are some images

Micropower? What is that?

Any other suggestions?

How about a pocket eBook reader to compete with MIT's $100 laptop - you could aim lower end. I see handheld PDAs that sell for $5 on occasion. With the amazing ability to build things cheap, and multi-gig SD cards available, you should be able to build a small device that alows access to a complete education from learning to count and read to college level physics, electronics, etc. I have been collecting information for such a device for years, and have 60+ GB right now.

We'll see 60GB SD cards by the end of the decade...then we'll see them in dollar stores a few years later. The upgradable flash ROM will allow you to upgrade your system as new cards become available. The ability to upgrade from a SD card (the way my MP3 player does) would make upgrades in the field easier.

It should have a small but readable screen (black/white 4 inch screens would be ideal, if readable in daylight and total darkness,_ a small processor, maybe an AVR or an ARM, (upgradable) software that allows it to read many eBook formats, including XML, HTML, PDF, DOC, etc.

I'd put in multiple SD card slots, so that you could concurrently plug in a pair of 2GB SD cards, a Wi-Fi SDIO card, and a GPS SDIO card. The first SD card slot needs 4 I/O pins, and each extra one only takes 1 pin. SD cards give you the serial equivalent of a PCI slot.

The power supply should be very efficient and very flexible, since electricity is more costly in developing nations. The battery pack should be easy to customize, os that you can run it off of any local power supply (e.g., dry cells, an old car battery, or 440V aircraft power.) MIT made their power supply / battery pack removable, and roomy to allow custom units to be improvised in the field.

Internal storage for many more SD cards would be a nice plus.

A headphone jack, and the ability to decode MP3s is nice, as it would serve as a limited sound card. A built-in speaker would be another option, though teachers would perfer an external speaker to preserve classroom atmoshpere.

The user interface could be a simple joystick. 90% of the time, no typing would be neccessary. External plugs for a keyboard, mice, and monitor would be nice, but the monitor might be overkill. Conenctions to a keyboard port for an AVR are detailed in the academy.

Micropower (in my mind) is the study of how to design circuits and systems to take very little operating power.

Data loggers seem to be a popular project. You have to deal with interfaces to sensors and with (either) data transmission to a distant site with larger scale data storage OR storage that is external to the processor. If you do the latter, then you need to be able to hook it up to a data processing device (ie, PC) to download the data. These often turn out to be a bigger project than one might expect.

Robotics is also a very popular project. People build line followers, balancers, battle-bots, and more. You will find LOTs of references if you look back in the message archive. There might be some room here for a smaller project. Think of something with just one motor that does a very simple thing, maybe?

I would like to suggest using a small micro (one of the TinyXX, perhaps) to do signal conversion of a sensor. Choose one with an output that is difficult to work with (variable frequency, variable pulse width, very low analog amplitude, then use the small micro to convert that into a more common interface type. The micro could be used to linearlize a nonlinear input function, or simple processing (like convert input rate of change into an output parameter). Something of this sort could actually be useful to others.

What is your hobby? Music? Cars? Best to work on a project where you are the subject matter expert.

Afraid that my primary hobby has nothing to do with electronics. Secondary I’m very interested in computers, maybe some tips for doing something useful would be ok I think

Whats the grading criteria? You get more points for solving Fermat's Last Theorem or some new original invention? Or do you get points for taking something common like a computer or a phone and making it smaller and faster? Do you get points for something simple that works, or something ambitious that almost works? Is it a programming degree or an EE degree? (Doesnt necessarily need a computer in it? Could be a cool new circuit like in EDN magazine?)

Hi,

But maybe you can find a way to incorporate something electronic into your hobby field. Who knows, maybe you could find and design the next "killer app" and get rich. It may be that you are just looking for something to get you through this class (and I am not criticizing you for this) but if you can have some fun along the way that would be great and I bet you would get a better grade.

Sorry for preaching :-)

Regards,
Steve

Well, your hobby might be golf, so we could do some kind of electronic golf gizmo. I knew a bunch of guitar players who had a primary hobby of getting to know lots of strippers. Pretty far stretch to work electronics into that hobby.

KA7EHK,

Do you QRP? I've been thinking about trying it... I think it would be very challenging.

I suggest a motion controlled dollar dispenser for lap dances. Differen't dispense rates dependent on x, y and z frequency and amplitude. It could rate the dancers on a scale of 1 ~ 10. Maybe they'd lap dance for free just to beat the last wench.

To continue the thread hijacking (though somewhat on topic)...

Can anyone think of a hobby that couldn't involve a microcontroller?

What about a self-contained Tomato Grow Box?

Have it control lights, water, vents, etc. Sense
Temp, humidity. Time clock for cycles....

Use angle iron for frame and sheet metal for box...

Say about 36" x 72" x 48" in size...

You could use it to grow tomatoes or something.

STOP!

NO!

DO NOT EXPERIMENT WITH HYDROPONICS!

Accoridng to certain JBTs (Jack Booted Thugs...a demeaning term for federal SWAT teams) they are entirely illegal.

It hasn't to be something very hard to make, originality is better. Something simpler that works would be better and there are no restrictions about programming and EE. I can combine both

Deepmeter for your'e inmersions. Also inmersion crhonometer and deep data logging could be interestin to your. An small ATtiny88, SPI/I2C memory with realtime clock for datalogger and a coin size lithium battery. Sea water pressure sensor (50psi?). Quite small application, but doable although IP68 is required.

If you want LCD then a Mega small in size coul be interesting also.

An engineer here at work scuba dives as one of his hobbies. He designed, built and tested some sort of dive monitor (I don't know a thing about scuba diving) and had an article published about it in Circuit Cellar a few years ago. Somewhere on Atmels AVR site I have seen that article as well...it used the AT90S4433 or something like that.

Last time I wet a line I caught a tire. I caught a javelin once, but I never caught a spear.

You can get the Dive Monitor article at:

about half way down titled:

Under the Sea: Designing a SCUBA Dive Monitor with the AVR AT90S4433 (4 pages, updated 6/04)

What about one of those electronics shark repellers? Just control it with an AVR. Supposed to be virtually fool proof, you just have to create a very low current high voltage signal (AC or DC I don't know) between the head and feet of the diver (preferably without killign the diver) Supposed to basically fry the electric field sensing ability of sharks and make them head the other way in a hurry. Kind of a like electric hot sauce.

How about a GPS controlled Shark detector? It would search around swimming waters and have an onboard camera. It would send pictures via radio to a receiver that would analyze them and give an alert if a shark were found.
Each detector would have its GPS controlled area to scout, modifiable remotely.

Its a little uav boat right Ralph? Like the glass bottom boats at Silver Springs. Don't those lcd fish finders at Outdoor World draw pictures of the fish they see? Just telemeter that back to port somehow.

hi, one really good idea to impress people
( i impressed myself with that )
is an mp3 player based around VS1001,
quite a few people here and there have been playing with that,
many things can be added.
there is even a dedicated forum...
remember not to copy/paste ...
