Playing with some animations of the single LEDs strip of my NeoPixel board was nice but the thoughts soon come to mind: “It would look better if there were more strips”, “…if there were more strips, how could they be coordinated”, to “Could I still use the ATiny1614?”.
On Saturday we saw a flood of interesting hacks come to life as more than 100 community organized meetups were held for World Create Day. Thank you to all of the organizers who made these events possible, and for everyone who decided to get together and hack. Students Learning Hardware Design in Islamabad, Pakistan The…

2018.03.18 : BML project for using a $2 FTDI FT260Q for adding 14 bits of GPIO to any PC via USB with no device drivers required. Ever miss the simple days of using a PC’s LPT1 parallel port to bit-bang GPIO over 8 output pins and 4 input pins of the DB-25 connector? I sure […]
tl;dr So when I was into using just a atmega328 dip chip I make a programmer header for it that also had a crystal and the capacitors need to make it function. I wanted to do the same for the attiny85. As you know you have to use a ISP programmer to flash the […]

The Hackaday writing crew goes to great lengths to cover all that is interesting to engineers and engineering enthusiasts. We find ourselves stretched a bit thin and it’s time to ask for help. 161 more words
For my current project I searched for a good boost power converter which is able to deliver continuous 400mA power for various sensors. There are an endless number of good boost converters around, but not many can be hand soldered to a board. I would really like to see some with SO packages. It seems […]

Love them or hate them, Nixies are here to stay. Their enduring appeal is due in no small part to the fact that they’re hardly plug-and-play; generating the high-voltage needed to drive the retro displays is part of their charm. But most Nixie power supplies seem to want 9 volts or more on the input side, which can make integrating them into the typical USB-powered microcontroller project difficult.
Fixing that problem is the idea behind [Mark Smith]’s 5-volt Nixie power supply. The overall goal is simple: 5 volts in, 170 volts out at 20 mA. But [Mark] paid special care to minimize the EMI output of the boost converter through careful design, and he managed to pack everything into a compact 14-cm² PCB. He subjected his initial design to a lot of careful experimentation to verify that he had met his design goals, and then embarked on a little tweaking mission in KiCad to trim the PCB’s footprint down by 27%. The three separate blog posts are well worth a read by anyone interested in learning about electronics design.
Now that [Mark] has his Nixie power supply, what will become of it? We can’t say for sure, but it’ll be a clock. It’s always a clock. Unless it’s a power meter or a speedometer.

We miss the days when everything had daughterboards. Now, Arduinos have shields and Raspberry Pis have hats. The BeagleBone has capes. Whatever. However, regardless of the name, the open source… 239 more words
