Microprocessors are the future

[cavalry]

Looking at various designs using PIC micro's and Arduino's but they are all lacking.. I was thinking of a new design and it would be ideal to have re-useable modules. Obviously the micro has to control the display and depending on the design it can control just about everything else. Most microprocessors do not have the speed required but I believe I have found the ideal candidate. If you watch this video you will also see that, although it is about audio, it does cover almost every aspect of a good metal detector.

In my opinion microcontroller in the Vlf-world are only good for good stable Id-numbers and some filtering in ground or multifrequency (Fbs,Bbs and so on). For good seperation and speed and when you dont need a display..... i think "analog" detectors are the best;-).

Did you watch the video

I think it's an eye-opener.

sorry, but only russian. you see a code http://www.md4u.ru/viewtopic.php?f=94&t=10067
why russians? i do not know. i always wait something from western world but western world is given nothing.
i mean certainly arduino.

I think russians not want to make big money with every little invention and have fun in sharing improvements with other enthusiasts. Russians are very good inventors and very good in improvising;-). You should be proud of it;-)

Interesting..design...I have seen it before but the actual construction put me off. Maybe it is better than it looks and I will have a closer look.
I'm playing with a 32mhz PIC just now but I'm no expert.
The Arduino's a re a bit slow but the teensie takes speeds to new levels.
Hopefully I will be able to post some code soon.

The design and code are not russian, the author is David Crocker (dc42) from Escher Tecnologies, UK.

Here's the original repository to download the code from: https://github.com/dc42/arduino

kt315 How long have you used that name? the reason I ask is that I remember about 20 years ago I was in contact with someone with a similar name.
In fact I made a PCB layout for that person in exchange for a schematic.
I'm probably mistaken but interested to know.

hmmm.... thats only school alias given to me by classmates. so it is very old. i had visited electronics section
of school and was a radioamateur. so it is not mine and yup... this is soviet kt315 NPN transistor, legendary one.

Haha...I forgot about that transistor and that's probably why the name seemed familiar.Please forgive my stupidity
