An anti-Etching PCB Maker lets you hand draw the circuit so after the etching, the underlying copper is not lost to the chemical. Fast and easy hack for prototype boards.
Yes, it serves it purpose really well. This is the only 0.5mm marker I found which can survive the etching process using Muriatic acid + peroxide.
Bad part - The super fine end (0.5mm) works, but it goes dry every few seconds. So, I have to draw 2 lines on copper board and then squiggle it on paper to make sure it has good ink flow. If it doesn't have flow, your lines will suffer and you have to rub on it multiple times, giving you a bad result. Using it at perfect 90 degree angle helps. The fine end (1.2mm) almost doesn't give out any ink and is bone dry. I think they were stored for a long time and so have become quite dry.

Anti Etching PCB Ink Marker
Worked beautifully.
The product photos show a group of three pens. One is likely to be misled that one gets three pens for Rs.40/- but one gets only one pen for Rs.40/-. The thing that sucks is that the pen costs Rs. 40/- but shipping costs Rs 90/-. So while ordering this pen, order as many other parts/components you will need to spread out the shipping on a large number of components.

Case is nice and sturdy all ports are perfectly aligned it has enough room for hat , especially if you want use Geekworm X1002 PCIe to M.2 2280 hat for nvme.
The only thing is missing is heat dissipation cut outs on the top of the case , If it has heat dissipation holes on the top it will be much better however case is having many cutout on the front bottom and right side but , for active cooler to release instant heat top side cutout will be much better .
Next thing it will be better If it comes with rubber feet so that in case we don't want to mount on wall we can place on table little bit risen up from the surface.
It comes with rail mount and wall mount which is very good.
with offical RPI5 active cooler and if cooler is not running (only passive heat release)the ideal temp of pi 5 stays around 53 degree Celsius when room's ambient temperature is around 18 degrees , and its running on raspberry pi os .
what will be the temp. on summers that i yet to experience.
