Hi!
I got a nice Digimess DM200 bench dvm (Mastech M9803R clone) sold as seen on ebay but it looks like the NJU9210F dvm chip has died - no display, backlight works but nothing else!
Can anyone point me in the direction of any new (preferably less than £20!) cheapo DVMs that use '9210F's I can...
Hi!
Can anyone point me in the direction of Circuit Diagrams for the GW-Instek GAG-809/810 Series Wien Bridge Audio Generators please?
I got a Tenma-branded one (72-455a) which is the clone of this, but I feel my friend would prefer the 0.02% distortion of the higher spec version!
I can...
Hi!
Further to the above, the LCD is marked "FPC1602-021 A0" and is dated 2010-03-30 - from the 11 connections I assume its a 4-bit interface type (D0-D3, EN, R/W, +Vcc and 0 with one or two spare/unknown but I still can't match it up with anything - parallel ones have 14 pins, I2C ones only...
Hi!
Can anyone help me with this enigma please?
I picked up a Bush NE3160 DAB radio which works apart from the LCD being totally blank, and on taking the front panel to pieces I was distinctly annoyed to discover it was one of those tiddly ST7032-based COG LCD thingys (16 x 2 I presume!) and...
Hi!
Can anyone offer any help with:-
1) A circuit diagram for a Logik L22L618B 22" LCD TV fitted with the
MTK5330CI_DVD_1.08 PA-0199-2--4TG -UMC E22/13B-GB-TCD-UK -MAIN BOARD
please? I have one of these sets working but no LCD illumination! The TV/DVD is otherwise working and plays DVDs OK...
Hi!
My friend has recently acquired one of those Dimension 033 7" GPS/DVD/Music Player/ebook devices but unfortunately it turned out to be the one not having a Bluetooth chip and he really wants this facility!
An e-mail to his original supplier confirms it's physically not present, so can...
Hi!
My friend's Hotpoint Aquarius+ WF740P washing machine has developed a fit of the collywobbles following drive-belt replacement, stopping in mid-cycle with error codes F-08 and F-10 showing up on the front control display!!!
I suspect the internal EEPROM has become corrupted in some way due...
Hi!
What's actually wrong with yours? As Member SunnySkyguy says these things are usually easy enough to reverse-engineer!
"H-E" on the display indicates the iron's heater circuit is o/c or poorly connected, whilst "S-E" indicates similarly for the sensor thermistor incorporated in the iron -...
Re: Is it safe to use electronic devices & accessories with portable Generator's outp
Hi!
A further point I ought to mention is that some of the smaller and cheaper generator sets use a permanent-magnet alternator, and with these the output voltage will be fairly heavily dependent on the load...
Re: Question about a PCB
Hi!
For specific educational purposes there's much to be said for the OP's approach! I found that something called "Mota-Kleans" which comes in an aerosol tin will dissolve silk-screen ink - it also melts plastics wholesale as I found out when I tried to clean a...
Hi!
I'd be interested in the construction details as well please! Schematics and a parts list would be adequate as I'll make my own PCBs but if you're willing to share the Eagle files plus a programming file for any microcontroller you've used there'd be a lot of extremely pleased chaps here...
