Welcome to a new Voltlog, today we’re going to take a closer look at an ultrasonic cleaner. This is the 1.3 litre, model number I believe is Y-009, the ultrasonic power is 60W while the heating power is rated for 100W. Usable area I’ve measured to be 125x115x40mm depth which is not a lot but I’ve thought about it and this is pretty much all I need. 99% of the PCBs I design fit within these dimensions so it’s not worth getting a bigger ultrasonic cleaner because it will take up more space and it will use up more cleaning liquid, it would be a waste of resources.

Voltlog #214 – How bad is a fake apple lightning to 3.5mm audio adapter?
Welcome to a new voltlog, today we’re taking a look at these lightning to 3.5mm audio adapters that you have to use ever since apple removed the 3.5mm jack on the iphone. So you know the story, apple removed the jack and said it’s because they will free-up space inside the phone and it makes it more waterproof but if you ask me that’s bullshit, they removed it to force people to buy bluetooth headphones. But anyway we won’t go into that, this video is about the adapter that they now give people to still be able to use the 3.5mm jack for audio.
This made me wanna take a closer look so here are the two adapters, the plan is to connect a 3.5mm jack, this will provide me with some contacts where I can probe with the oscilloscope. I’m gonna generate a known constant waveform from an app and we’re going to measure that and compare between the two adapters.
Voltlog #107 – Wowstick 1S Electric Screwdriver Review
This is my review of the Wowstick 1S battery powered electric screwdriver. The product was provided for free by banggood.com. I think it’s a great tool but I would’ve liked to see a bit more torque.

After replacing the battery in this iphone 5c, the phone kept rebooting itself without any apparent reason. By using a schematic and board view of the logic board I was able to find the fault and repair it.
