haven't had any issues using a 28BYJ-48 12v but my camera isn't that heavy being a modified dSLR, my focuser easily lifts the camera vertically, and yeah daves focuser code works perfectly over bluetooth

Not sure if any of my fellow arduino tinkerers have seen these but WOW!!!

have a gander at these specs and the board is about the same size as an arduino nano and that's WITH a 128x64 OLED screen... these things are AWESOME!

got one through the post today and have it connected to my wifi in minutes.

there's quite a few form factors but i got this one... and only 12 quid

oh, it can also run Python... 

ordered a howie glatter laser late last night, it's arriving tomorrow...

they answered a query at almost 9:30pm on facebook, almost immediately... now THAT's premium customer service

i love you FLO and i want to have your babies ?

just posted this on their facebook.

"must say that i'm REALLY disappointed with altair... i've sent messages over facebook and messages through your website since last friday, asking for information. not a single response... now, if what would have been over £2000 in purchases is of no interest to you then fine, so be it. as it is, even though i was really wanting to get one of your 10" truss imaging newtonians, because of your shockingly  bad customer service, i'll be taking my money elsewhere."

just stripped and regreased the eq head... there was a bit of slop in it i wasn't happy with. considering how simple the eq head is, it's now rock solid and quite smooth

Really? Your first proper scope since the age of 7??

Enjoy, it should perform really well.

Nooooooo.... my first refractor  there's a 'proper' scope behind it lol

well, the lens wasn't chipped at all... must have been some odd reflection. got it for £170 which may or may not be a bit higher than normal, but i've wanted one of these for years so i really don't care. can't wait for a clear night  

this is the first frac i've had since i was 7

this kinda puts me off tho... definitely looks like the lens is chipped.

Anyone know the going rate for a tal 100r? Been  after one for ages and one on fleabay is reasonably close but starting at £200

looks the business...

And I thought BT HomeHubs were supposed to have exceptional WiFi  

*correction 'And I know BT HomeHubs are exceptionally crap'

not that i actually need it, but i just got a precision piezo board and a few disks through the post today. did a temporary wiring up the the duet wifi  z-probe connector and it triggers properly when i tap the piezo. time to break out sketchup and redesign my extruder carriage. not too keen on the housing from the video as it adds a lot of extra length to the e3d mounting

just don't press the erase button

is it me or is the 'duet club' now a trio?

yeah i usually print on glass with no problem, but, if you don't try these things you'll never know

printing on it

just on a side note, have a look at Diall Aluminium Tape (i got a roll from B&Q) no kidding, i just put some on my glass bed and i'm getting the best first layers i've ever seen on this printer

That's much better   I'm quite looking forward to trying my Duet Wi-Fi board.  My Mini printer is not far off finished now and once that's working with Mega/RAMPS/LCD control panel I can try the Duet on it.  Which printers end up with Duet boards remains to be seen

once you've tried it... all of them

the GP payload is underrated... i've imaged with my 10" newt (12kg all together) on one without any issue. so good in fact that even though my az eq6-gt arrives today, i might just hang on to the GP and stick a 6" F4 on it for wider field stuff.

told you you'd like it

That looks good. Why not post it on Thingiverse - lots of people would find it useful.

I was planning to make a case with a fan beneath the pcb where duet recommend the cooling is applied.

the outlets are at the back of the mobo and i'm using positive pressure to force the air out the back and upwards away from the print area

bask in the total wonderfulness of the duet wifi

dunno if this is of any interest but i'm just finishing off a duet wifi/mosfet modular box linked together with 14.5mm non-split flexible conduit for cable routing. you can have the file if you want it

ooohhhh shiny

Not astro related, but when your nerdy hobbies means that no-one has a damn clue what to buy you, you end up buying your own prezzies

this is how quiet... tablet was 10 inches away
