Whites Eagle Spectrum

[[email protected]]

with care!

If it can be opened, then I may be able to fix the lights, probably each side of the LCD display. I might be able to fix some blue LED's at each side cool??? Or just a Dream on dude??

Hi,

Display board schematic if somebody are interested.

I have one Eagle Pro. Does anyone has the schematic ???
Btw.... Rael, thanks for your schematic.

Martin, Don't bother you won't be able to fix it. I whould know I run Pulsar Electronics and I have one of these machines myself. The backlight is a cold cathode flourescent membrane cannot be repaired, they go short circuit and kill the DC-DC inverter (usually gives around 80V) You can verify this by doing the following;

Go to menu and switch ON backlight, set to level 6, LISTEN CAREFULLY to meter pod, you should hear a very high pitched but faint hum. No hum = RETURN TO WHITES. You will no be able ot get the parts to repair it.

About these machines, I have a HOW TO guide on how to set them up PROPERLY. I once challenged a bunch of ML Expoder users to a dual with the losers machine AND a £1000 CASH prize to the winner, I got NO takers.

I used to go to rallies and haunt ML users. I followed them and dig what they miss. If set up properly, you will NEVER dig iron with this machine and it will find hammered at over 10" even in bad ground. One of the deepest machines and BEST EVER made.

People say the Exploder is programmable ROFLMAO what RUBBISH (machine and the claims made for it oh, AND ML too), this IS the only truly programmable machine out there STILL.

Hey Ivconic, how about adding a USB interface to your Eagle Clone then we could share programs online ??

Hey Sean...
Something for me ?????

Lights out?

Thanks guys,
As the machine works fine other than this, maybe I'll leave well alone, but I had thought maybe some small leds next to the edge of the display glass, IF I could open the case! Maybe a small torch is a better option? But, hey! You fellows are a great help.
Yes these spectrums are a great machine, they do penetrate quite deep and discriminate very well. I tend to dig everything and dump the trash properly. That way you can visit again and again. Even `experts' miss stuff and if you remove the trash each time, the site can only improve! I've known finds turn up under the trash too, so sometimes it pays to be a good boy!

hi could you post or send me the whole schematics for the eagle spectrum, i would thank you very much

Sadly...but you are right Sean. I also have one dead Spectrum. DC-DC converter dead. Once 78s40 replaced dc-dc started to work somehow but still with huge (to me still unknown) drain from the rest of machine. I checked almost everything and found nothing. Last i suspected was uPc... Am i right or not? Now...reading your comments i am starting to beleive uPc is not dead...Haaalleluujjahhh!

USB...? Ha! What we need is simple onboard eprom reader..



P.S.
Say......He can always cut backlight and void further damages? Right?

[Sean_Goddard]

Remove X1 (potted module and transistor driving it. Dc-Dc goes short causes LARGE drain when light it "on" well NOt if it aint working. You know what I mean

[ivconic]

Exactly!

[ys_dev83]

did someone have the data from the 93C46N, i would like to build a clone Eagle Spectrum II from scratch....

any help a welcome thx

[Daemon]

That data didn't do anything for you, it's just user programs' coefficients. Main code located in both MC6805 that are read-protected.

MC6805 microprocessor unit?????

That data didn't do anything for you, it's just user programs' coefficients. Main code located in both MC6805 that are read-protected.

I just looked at the 4 Whites factory schematics, that are mentioned here in links, and they do not show the MC6805 Microprocessor, which is a smart card technology chip (I believe). I believe the chips starts out like MC68HC05****, or similiar to those numbers. If so, it is a high secret, Motorola smart card chip, which has not been broken in, except for some Russian hackers and a hacker in England, getting his doctors in hacking such secured smart card chips...

So lets hope, that the following information is actually true, and not that statement above....

What they show is the older Microprocessor chip, the MC68HC70508 chip, of which there are some reader units for, and often the eeprom sections are not secured, but often the sram sections are secured, but not always!

But of course, one would expect that all of the main part of the microprocessor is usually secured, which contains the guts of the metal detector.

But every now and then, one finds one of those chips that someone forget to set the security bits... I know, as in the analog cable boxes, that was our experience... In fact, in the General Instrument encoder box, it was one of those "purportedly secured" chips, that was found "not secured", and read, and it cracked open the General Instrument analog cable boxes! I was privy to that knowledge. I do not have the detector, or I would hook up my "after market" reader unit...

Hi Melbeta.

If you like I have a spare (working PCB) you can borrow, but I MUST have it back in working order, so no fancy "hacking" of the MPU please.

This is the ONLY remaining spare PCB for an Eagle Spectrum in the UK AFAIK and I need the board back in case mine ever dies.

PM me your details and I'd be happy to ship it to you for you to experiment with.

BTW is you look up Whites patents on the web, you will find code for the Spectrums display graph in full for ALL to see. Go to the ORIGINAL geotech URL and look at the patents there, failing that try [email protected] (patents)
