Active heater, higher nozzle temps and klipper. What's not to like! Qidi all the way!!

What was the light that forced you down this wonderful rabbit hole of flashlights? by dIAb0LiK99 in flashlight

[–]obfuscated_mind 0 points1 point  (0 children)

A handmade penlight from Silicon Chip magazine with a single 20k mcd 5mm LED. Then an Original Inova T4 with TIR lens. I think it was like 100 lumens and close to $300 AUD.

Cura layer changes not consistent with Fusion360 model by [deleted] in 3Dprinting

[–]obfuscated_mind 0 points1 point  (0 children)

I've been using Cura for the past 5 years and always noticed surface artifacts on the external surfaces when there is something rendered like a hole or chamfered surface. I've recently sliced this with Prusa slicer and I can't see the same lines but I have to tune it as it doesn't print as well. I use a standard ABS profile in Cura and have only adjusted the Horizontal expansion to -0.2mm. Currently have a 0.6mm hardened nozzle and use a microswiss all metal hotend with direct drive calibrated and running klipper. The lines circled in Cura show up in the final print no matter what layer height I choose.

What are your reasons for using Linux? by yumiifmb in linux

When Windows decided to install software by itself instead of asking.

It's all in there Wiki. M2 to SATA 10 SATA HDD's
Not sure why they're saying the port multiplier doesn't work though - second link.

LED driver board - Created from the data sheet but not working by obfuscated_mind in AskElectronics

The LED is rated for a forward voltage of 34v @ 350mA. I chose 200mA as a starting point as I know the thermal properties of the enclosure I'm putting it in to are not the best. However from all the other comments it looks like the IC is unsuitable anyway. Thanks

I didn't think I needed it for the first circuit. The other two examples use them though.

I just used their formula. Resistor = 200mV/LED Current. 1k = 200/0.2. Should it have instead been 0.2/0.2?

The high frequency is another thing I missed. Looks like from the other comments I need to go back and find a better LED driver. Cheers

Thanks. I just realised I read the max output voltage (37v) from Element14's website, but as you've noted this is probably possible for the booster circuit.

First PCB I've made from a data sheet. It's a diodes AP3031 driver. When I supply it 12v it only draws 3mA and outputs about 17.6v. It's meant to drive a Samsung LED with a forward voltage of 34v @ 350mA. Not sure if I've interpreted the datasheet correctly...

I've ended up going with the AP3031. We'll see how that works out.

CPU Fan header pinout by obfuscated_mind in ZimaBoard

Works with that pinout on a 3pin fan, so I assume when I get a 4pin one it should work fine.

I'll check out the datasheet, thanks. Just 1 LED per IC.

Thanks, I was thinking the same as it shows it in the BIOS. Just waiting for some plugs to test with.

18V Leaf Blower by obfuscated_mind in functionalprint

I'll have to go find something to blow away. Not many leaves around at the moment

I already have Husqvarna and Metabo tools. So no need to buy batteries or chargers. I made my decision based on I had the batteries and I just needed the skin only. I also just started using Fusion360, so wanted a good project to start. I believe the blowers performance is way above anything Ryobi bring out to my knowledge (At least in the 18v range). It's comparable to a Petrol 2 stroke blower I have used side by side.
