General Discussion / Ordering from QRP Guys
« Last post by Andywragg on January 15, 2018, 06:02:56 AM »
HI Guys

I placed an order last week from QRP Guys, and got a transaction receipt from Paypal, however I have yet to get any emails from QRP Guys re shipping Etc.

I know Gil has ordered from them before, what was the experience like?


Best regards

Andy

Cool find Gil. They would make a cheap 6 meter radio in the US. I didn't find anywhere on the site where it tells me what mode it operates in. I'm assuming its SSB though. It would be fun radio to take portable and operate on 50.125.

This is the one I have.
https://robo3d.com/products/r1-plus-3d-printer
I got it 2.5 years ago mostly for my "engineer from birth" son.  I paid $850 for it.  It's print volume is 10" x 9" x 8".  Of course you can make bigger things in multiple pieces and glue them together.  Printers keep getting cheaper.  There's $250 kits that take about 6 hours to screw together that work very well(sorry I can't remember the names).

Bare in mind that there's no magic in these printers and often not a lot of difference between the $300 and $1,000 ones other than a pretty enclosure, display and no need to be connected to a computer.  They all have a heated print bed, 3 axes of stepper motors, an extruder and a controllable print cooling fan.  Most use the exact same set of Arduino boards and software to run them.  The good ones are a bit more accurate because they are stiffer.  The expensive ones use guide rods bigger than 6mm, but my printer with its 6mm guide rods does great work.

Merry Christmas and Happy New Year everyone! ;D

All I wanted for Christmas was some time with the family out of the house so I could throw breakers and track down why I have S7 to S9 broadband background noise :P

I got my wish, but it didn't work out the way I hoped.  Last year when I threw the main breaker the S7 to S9 noise would go to S2 or less.  Now it looks like my neighbors are making noise too because now the noise only drops 1 to 3 S-units when I throw the breaker.  Having their noise mixed with mine will make it harder and less useful to find my noise sources ???.  Funny, but I'm looking forward to the next major power outage.  I'll run my house on my generator and the only noise sources will be mine.

It's a good thing CW gets through almost anything ;)

Gil, I just renewed :), a few months late.  I'm always late with this kind of thing unless I'm sent a reminder ???.  If there's any way to set things for reminders when the subscription is about to expire that will help.

Thanks Bob.
Just out of interest, how much does it cost to print a box?
I have a 3D printer and for the common materials (PLA or ABS) it's about $0.75/oz.  It's even cheaper than you might think because for areas of an item that have a lot of volume you tell the printer software to fill the areas with honeycomb of whatever density you want.  I use anything from 20% "infill" to 100% infill.  It saves weight, materials, print time and you lose very little strength.

Printing is a slow process.  I think printing all the parts for a uBITX box would be about 15hrs of printer time.  That's OK since it takes 5 minutes to set up a print, then I just let it run over night.
