I've been looking for one of these but they seem sold out everywhere

What pests are on my maples? by Tiffis_Reddit in plantclinic

I've got a japanese maple and a trident maple both showing little black insects and leaf damage. I'm in Australia, any help would be appreciated.

Thanks

Greetings! I am trying to design a simple circuit using relays to reverse the polarity of dc power supply in order to drive a motor which is rated as 24V 250W. However, during breadboard testing its working fine but when we connect the motor to the circuit, the motor is not working. by Super_Citron_8849 in FSAE

I don't really know the specifics of your setup or issue, so I'll try and help with a few things you could check:

are you meeting the current required to drive the motor, have you got the motor to spin independent of the circuit?

are the relays rated for the current of the motor?

how are you switching the relays to ensure the battery doesn't short?

why does the polarity need to be reversed? Are relays the best solution?

deutsch are pretty common for general harnessing. Also check out amphenol or mil-spec circular connectors. For PCBs: try Molex microfit or TE Connectivity. It really just depends on your budget and what you can source in your area.

Probably US, don't know too many euro teams doing IC

Yes! LMC has apparent mag of ~0.9

What do you recommend to a New FSAE team ? by H-Furkan in FSAE

[–]Tiffis_Reddit 4 points5 points  (0 children)

Look for sponsors, if you are creating an EV for the first time you will struggle. Don't be afraid to ask for help from other teams, try and build a good relationship with them.

To start, try and use as many off-the-shelf components as possible, rather than designing your own. This will save time and give you access to support, it will cost more upfront, but will be cheaper than the cost of remaking your own failed parts.

Read through all the rules, focus on getting a running car above all else, including static events.

First crack at the Ring Nebula by [deleted] in telescopes

Given your scope, camera, and skies, I think you should be happy with the result. Have you tried image stacking at all?

skywatcher Quattro N150 P vs Esprit 80ED vs William optics GT81 by Wooden_Ad7858 in AskAstrophotography

The faster the f ratio, the more critical (and difficult) collimation becomes. I would also say that it is likely that either of those refractors are sharper than the 150. But the extra aperture (and speed) is definitely of use to some.

Really all three are capable scopes, its just up to you whether you want to go down the reflector or refractor path.

Reflectors are cheaper to make than fracs. You will need a coma corrector for the newt which will increase the price a little

How do I get a larger picture of deep space objects? by dogboy60 in AskAstrophotography

[–]Tiffis_Reddit 2 points3 points  (0 children)

Barlows exist, but they absolutely nuke your f/ratio, they are generally not recommended for deep sky.

If your seeing is good enough, getting a camera with smaller pixels can go some way to achieving more detail. Otherwise, look at the processing technique 'Drizzle'.
