<r><br/> <br/> <br/> <br/> <br/> Hi Stew,<br/> <br/> <br/> <br/> With respect to the frame, how did you make the 90-degree bend in<br/> the brass strip?<br/> <br/> <br/> <br/> Did you use the same brass strip for the fencing on the SLIM's?<br/> <br/> <br/> <br/> Steve, K8JQ<br/> <br/> <br/> <br/> On...

Re: Machined aluminum frame

<t><br/> <br/> <br/> <br/> <br/> Hi Greg,<br/> <br/> <br/> <br/> I'm glad to see some discussion about PCB mounting. My MSA has a<br/> carrier made of FR4 PCB material . . . difficult to construct,<br/> difficult to make it look half way decent (I didn't). An alternative<br/> would be welcome.<br/> ...

Fwd: [spectrumanalyzer] Making enclosures for SLIM's

<r><br/> <br/> <br/> <br/> <br/> <br/> Scotty,<br/> <br/> <br/> <br/> Any thoughts good, bad or otherwise about using double-sided printed<br/> circuit board material as walls for SLIM enclosures? Thin FR4<br/> material is available that might be easier to work with than brass<br/> shim stock. Just ...

Re: USB control board and unpowered laptop computer

<r><br/> <br/> <br/> <br/> <br/> Hi William,<br/> <br/> <br/> <br/> Keep in mind that my observations were with the computer turned off.<br/> I verified that when the computer is turned off there is no 5VDC on<br/> the USB port. Your line of reasoning might apply if the computer<br/> were powered up...

Fwd: USB control board and unpowered laptop computer

<r><br/> <br/> <br/> <br/> <br/> <br/> One more thing: The output of my bench power supply is equipped with<br/> an ammeter. Normal MSA operation takes around 800mA at 12.5VDC<br/> input. In the posting below when I say the "control board LED goes<br/> off" I should have mentioned that bench power s...

Re: Making enclosures for SLIM's

<r><br/> <br/> <br/> <br/> <br/> Bill -- Thanks for that info. I have tried paper guillotine cutters,<br/> finding the small pieces of brass are curled quite a bit. Also tried<br/> scissors. My best cuts were made with an old pair of Wiss snips. The<br/> snips produced the least curl (deformation). ...

USB control board and unpowered laptop computer

<t>Hello all,<br/> <br/> <br/> <br/> You may recall from my recent postings that I have a complete MSA hay <br/> <br/> wired on my workbench. It has a Spyker USB control board attached to a <br/> <br/> Dell D610 laptop computer (yes, a rather old laptop). Although the <br/> <br/> SLIM's have no shie...
