[electronic_eel] is changing that game up with his own design for perfboard. This perfboard has the traditional 0.1″ holes, but there are SMD pads sprinkled about between these holes. The result is being able to solder SOIC, SOT23-6, SOT23 and SOT363 devices directly to a board alongside 0603 and 0805 devices. Connect everything with a few beads of solder and you have a functional circuit made out of surface mount devices on something that’s still compatible with the old protoboard designs.
I see, thanks for verbalising it. Sounds interesting, though a bit ringy in the ears due to acetone vapours.
Smartphones have literally changed the world. While there may not be flying cars in every driveway or teleportation devices in every living room, the fact that most people now have the ability to connect to the world wide web, send texts and make calls, snap high-quality pictures, and engage with millions of apps using a device small enough to tuck into a pocket is evidence enough for me that the future is here.
Since no one wanted to volunteer their own computer for testing purposes, the USB key was plugged into a spare power adapter, and immediately worked. The key was rapidly plugged in, then removed, over and over again over a few minutes, and the team marked it down every 50 counts. The results were surprising – the durable USB pads still hadn’t broken after 500 cycles.
As a transparent organic material surface finish of PCB, on the one hand, organic solderability preservative (OSP) holds an extremely high requirement for PCB storage and short craft time. Meanwhile, usually after one-time high-temperature soldering, the organic protection film on the PCBâs surface will be destroyed so that anti-oxidation capacity will be lost, easily leading to difficulties of second-time reflow soldering.
He sent headers wide and straight at Rui Patricio early on, blazed over from inside the box and scuffed a couple of other efforts wide with another blocked.
I played around with the acetone method for a day, and was never able to get results as consistent as with heat/pressure transfer, where I get results that can discriminate between 600 DPI and 1200 DPI.
A single wall charger is all well and good. A unit with a couple of ports is even better. But for the household or business with multiple devices to power up simultaneously, it’s time to go big. Though actually, thanks to its thoughtful, well-organized design, the Satechi 7-Port USB Charging Station Dock isn’t all that big in terms of desktop real estate. But it’s certainly impressive, what with its ability to juice up seven separate devices at the same time.

The UK has four electricity interconnectors, one to France, one to the Netherlands, one to Ireland and one to Northern Ireland, with the French and Dutch ones largely importing power.However, the UK’s rapidly changing energy mix, relatively high power prices and government support – which are backed in Theresa May’s Brexit deal – has set the scene for a rapid expansion in interconnectors.“As we’re going through the energy transformation, we’ve got a lot of changes in generation. Interconnectors are increasingly important,” said John Pettigrew, the chief executive of National Grid, which has built Nemo with its Belgian counterpart Elia.
