    Technics turntable's stylus specs required

    Hi all. I've been given a TECHNICS SL-BD20-KXA5 DC Servo Automatic Turntable System for repair and own use (to digitize my LP vinyls). Problem is: the owner attempted self-repair and possibly damaged stylus. Stylus is EPS 24CS, the orange clip-on shell as in photo. Damage was due to no...

    Series or parallel fans for max cooling ?

    Jet-engine or wind-tunnel design? My air-cooled 130 amp welding machine was recently purchased. Works great for home projects such as work-bench etc. with one drawback – duty cycle. The 5-inch (127 mm) diameter rear extractor fan cools the transformer while operating, up to the point where...

    New apartment getting shocked on light switch screws.

    Simple non-component trick, tried when car's door-handle would zap me in dry winter air: Close hand into fist rather than 'pointy' finger. Touch object with flat face of upper fingers first, or just punch the switch. Static may still arc, but feels less severe, then after discharge should be...

    2 questions about speakers

    Sounds like @Ben King simply wants to try a 'what if..' construction project. From previously making something similar (500T #33 wound on bobbin) with iron core, flat diaphragm "matched" to labyrinth speaker, the sound will most likely be poor (music) quality, resonant only at lowest...

    What can be happen if I use 10 inch 8-ohms speaker instead of 8 inch 8- ohms?

    There might also be clipping distortion, or overdriving the speaker, if driver's power rating is too low. As shown in the music-sample waveform, a drum-beat has a high initial peak, tapering off to zero. While a lower-rated speaker may handle normalized audio, these "kicks" may clip the amp...

    Is BB code general use or made specifically for this site?

    Hi. As an amateur coder in HTML, I've read with keen interest your tutorial on BB code. It looks very similar to HTML, with tag delimiters <> being replaced by []. Just for curiosity, is this a code developed specifically for EP, or is it used in other applications? And what do the letters BB...

    Can hall effect sensor replace 50K linear potentiometer?

    Preferably need non-mechanical sensing. Hi, I'm trying to design an electronic treadle-pot that can vary a resistance from 0 ohms to 50K (linear taper?). Input is 5V DC, output varies according to variable resistance. 1K series resistor appears to be a current-limiter (R=min 1K). Although...

    Measure spindle speed with a Multimeter???

    Many DMM's these days have built-in frequency measurement. Found (on Major-Tech and Top-Tronic DMM's) that they read sinewaves more reliably than square (maybe as square contains harmonics*). Also, according to their own manuals, voltage level should be at least 10V RMS AC. * Reads the...

    Can SAMSUNG laser printer toner errors be over-ridden? (Scan ONLY).

    Want to SCAN only without printing. My colour laser printer, a SAMSUNG CLX-3170FN, CMYK M/F, has a higher flatbed-scanning resolution of 4800DPI in full colour, as opposed to lower 600DPI colour-scan of (current) smaller mono laser SAMSUNG SCX-3405 M/F printer. However, this CMYK printer...

    Which DVD video format works best with TELEFUNKEN?

    The home theatre is a TELEFUNKEN THT-6000HDMIA. Original video format is mostly FLV with a few AVI's. PC uses VLC as media player, which plays all OK. After burning to 4.7GB DVD-R blank DVD's, some AVI's play OK, while others have poor or no sound. FLV's do not play or get recognised by...

    Optical Pickup

    Sorry, I didn't read every post first time round. I realize now what u want (faithfully reproduced audio waveform using optics). Also building an electric in spare time - with inductive pickup for steel strings. :cool:

    Optical Pickup

    Hi m1kem00re. I gather you're not looking at producing a square-wave, as feeding this into an audio amp would create major distortion (side harmonics), like over-driving a loudspeaker. Running my 6-string acoustic through an analyser, the average wave shape for guitar is somewhere between...

    Wives Say The Damnedest Things!

    My other half planned to do banking & shopping the following morning, so to remind herself, fixed her debit card to our steel fridge-freezer door in kitchen. Using two decorative Fridge-Magnets.:eek: Saturday morning, the card would not work. The customer-care at her bank told her the magnetic...
