For an uncalibrated scope, yep. For a calibrated one it's a steal, but they haven't connected a probe to the test source so I can't tell...

http://laserpointerforums.com/f39/fs-tektronix-digital-storage-oscilloscope-74750.html :-) I wouldn't bother messing with that old box; if the trigger's busted all is lost.

I've upgraded my scope; so unfortunately I must say goodbye to this fellow: It's a calibrated TEK TDS210 digital storage oscilloscope, and it works great. Has all the fun measurement and trigger features, plus what's down below: Bandwidth: 60 MHz Sample Rate: 1 GS/sec Record Length...

If you decide to spend money on a scope, make sure you buy a digital storage one; they are invaluable for recording transient waveforms.

Don't buy that ipad toy, and don't buy a Rigol. Tek and Aligent/HP are really the only good scope manufacturers out there, but I guess it all depends on one simple question; How much are you willing to spend, and are you willing to put up with cheap crap if you're spendthrift? I have a few tek...

I'm looking for an SSY-1, hopefully one with a working q switch. Let me know if you have one sitting on your shelf! :-)

Seems pointless; a clicky switch is hardly a noticeable loss in the entire system.

Re: WTB VTTC Service. Cores are far from useless without a bobbin; all you really need is a cardboard one or a PVC pipe. BTW, those cores are designed for 0.5V per turn, so place 240T on one side as the primary and 14T on the other to power the tube's heater. To run the tube at 1000W you will...

Yes, musical beat. Essentially what I need is a relatively low speed X-Y galvo, one capable of the 'liquid sky' effect, laser harp effect, etc. I have a 1.5W green laser, and until I find a galvo it's just going to sit on the shelf!

I'd like beam redirection, not Lissajous figures!

Hi LPF, I'm looking for a mirror galvanometer, one which would be suitable for directing a green beam to a new direction on every beat. Yeah I know, going to have to do a lot of EE for that but it's not THAT terrible. Willing to trade tritium lamps for one!

Ebay has recently been flooded with inexpensive metcal irons. metcal soldering station | eBay On a scale of 0 (radioshack) to 10 (weller), metcal is a 15.

Re: Stuff for sale Bump...

I'd like to get rid of this bag of 30kV 780pf pulse capacitors. These ones were designed for excimer & TEA laser use, so they can discharge FAST. Perfect if you'd like to make a nitrogen laser, or a vacuum tube tesla coil. $11 each, or 5 for $50. http://i.imgur.com/l03q8.jpg Edit: Price...

:wtf: Tektronix 2225 Oscilloscope 50MHz 2 Channel, used | eBay I suggest you buy this before you fry out some expensive RF transistors! Also, I have a feeling that somewhere the impedance isn't matched properly. RF circuits are very, very picky. I also suspect that mosfet met the undertaker.

Let me guess, no oscilloscope?

So what username did they register under?
