You could also try paralleling a few LM338 if you like, this way you don’t need as many parts.

Ok, if you must go purely mechanic you must use some power which is equivalent to the work that’s needed to be done. A solenoid (plunger) needs power and I don’t know how much since I don’t have the formula clear. Are you in shortage of power to spend in this project? I suggested the propane / igniter variant since this will consume very little power from the project. I don’t think a robotic arm or similar would be an option here.

Cell Phone "AA" BATTERY Replacement...
ante replied to NewToElectronics's topic in Electronics chit chat
A circuit diagram would help, some phones have a step-up regulator right at the input and some have a step-down. It is a good start to know which you phone has. -
Hi Mike, There are many kinds of voltage regulators, can you be more specific? I assume you understand the general term (voltage regulator)?
-
Hi shaiq, You can use compressed air, carbon monoxide, or perhaps a small amount of propane (cigarette lighter gas) and an igniter. Or, you could go mechanical and do it like we discussed in an earlier thread.

Hi Tkil, You can use a variable resistor in a circuit with a GaAs-tuningdiode if you like. ;)

Hi Claudio, Welcome to our forum. I’m glad to hear you find this place interesting and useful. I don’t think your English is poor; it seems to be above average among the forum members. ;)

Only 100 Volts difference in DSS 15Volts in V(GS) …. (10 vs. 25) I(D) …. (3 vs. 1)

Hi firfirik, Welcome to our forum. This circuit originates from an Elektor magazine (and book); I don’t remember which but its many years back. I don’t see any reason why it shouldn’t work. Hope this helps!

Hi shaiq, This is a DjVu file of the double issue July-August 2006 in English! ;) [attachment deleted by admin]

Hi AJB2K3, AOpen doesn’t seem to have any interference problems with tubes in a PC! http://global.aopen.com.tw/Products/mb/ak79gtube.htm Go for it, and good luck! ;)

how to convert ionization to readable signal
ante replied to mide40's topic in Electronic Projects Design/Ideas
Hi mide, What’s the wavelength and intensity? -
Hi mide, You can’t replace an NPN transistor with a PNP! The 3055 is NPN type!

Hi gimo, Note that 2SK818 is not exactly the same as 2SK818A which you asked about!

REQ: Electronic Circuits: Fundamentals and Applications
ante replied to a topic in Electronic Resources
Hi NanOp, Sorry I don’t have this book, but I’ll keep an eye out! The Puma needs Nuts & Volts July and August of 2006 , can you help? -
After decoding this: I gathered you want to know about the following: Yes IC1 is the current limit part. The current limit does prevent short circuiting. You can find a complete explanation here: http://www3.telus.net/chemelec/Projects/Power-Supply/Power-Supply.htm

Hi gearhead, They are printable, only adjust the size if necessary to fit your printer! I am sure you know the 2.54 mm (or one tenth of an inch) distance between the IC pins, use it as a reference!
-
This is one way to do it that works fine:
-
Hi tufail, Welcome to our forum. Sorry I do not have any schematic for you but these PSUs have problems with bad caps, so I believe that’s what you should check first. I hope this helps. ;)
-
Yeah, me too!
-
Hi Mike, Believe me, I was laughing during the last post! ;D You haven’t appeared like you where stupid before so I guessed where you where going with it. It was an obvious worst case scenario of curse! :D BTW, could we be sure that 1000 of the 50V diodes would survive 50kV? Will the voltage in such a circuit divide equally over the diodes (50V over each)? ;)
-
Hi Mike, Why use the 1N4001 (50Volts) instead of the 1N4007 (1000Volts) if you must use diodes from this family? ;D Why not use diodes for 32kVolts, not that many will be required? ;)
-
What’s the source of the 50kVAC and what’s the power (current)?
-
Hi nametc3, Welcome to our forum. The way to convert 50kVAC to DC is easy; just use an high-voltage rectifier!
-
Hi atoof, OK, that’s fine! Use an LM78S12 to get 2A for the drive motor and you’ll be fine!
