Revision 1 In first instance, we'll try to compare the performance with the #TritiLED. In order to do that, we'll assemble the following variant: Placing R8 instead of the TPL5110 circuit so that the LED doesn't flash. This will make it easier...
A simple resistor ladder Digital to Analog Convertor(DAC) was connected to PORTB.Then, a C code was written to vary the output in a sinusoidal pattern by writinga periodic sequence of values to PORTBKuttyPy with R2R DAC Connected to ExpEYES17 oscilloscopeScipy...
I received 5 populated boards from JLCPCB yesterday afternoon. I decided not to fully populate these boards since I had accumulated a few previous revision boards that had many of the components that I needed to make this one. Scavenging parts saved...
The idea for the project came when I was considering using power over ethernet (POE) for another project and wanted to understand how to implement it in something simpler beforehand. At around the same time I came across the affordable stack light units...
Entries to the final round of HackadayPrize are now closed. What does this mean? It means that today is the start of another day of development! Now, I have the following items in my backlog that have a high priority - SG-90 servo version of the servo...
Project Log 5: 19:14 hours - Brasilia Timezone - 15 September It took me almost 3 hours to reach there, first a bus, then a metro, then walking for an 1 hour. They apologised saying "the trash was collected yesterday" (yet, they swore beforehand that...
BOS offers a powerful remote memory read/write access functionality through specific Messages and APIs. This allows a module to access and modify almost any RAM or Flash memory location in another module in the array thus providing powerful synchronization...
OK everyone, thanks for coming out today for the Pentesting Hack Chat. I'm Dan Maloney, I'll be moderating today. Let's all welcome Eric Escobar to the Hack Chat. Thanks for coming along for the ride today, Eric. Maybe you can tell us a little about...
So, since the last project log, (actually, since Monday) I've actually switched microcontrollers twice: first, from the Nano to the Pro Mini, and then to the Pro Micro. (the Pro Mini doesn't have enough code space to fit the library for the OLED...
Making the face plate took a long time of planning... I knew I wanted brushed aluminum from prior experience but I did not have a good way to cut and machine it. Over the course of building a few amplifiers, I procured both a router and table saw. This...
Bought a used Sony thermal dye-sub printer. Printer came with a ribbon and 5 inch wide paper for 5x7 prints which printed beautifully. I loaded the 6 inch paper and ribbon which had streaks about 1/2 inch from each edge (really bad streaks). The destructions...
Seems that I am going overbudget. The initial goal was for doing this "undrer 300 EUR" but the material costs before laser cutting will be pushing me up to 325. With the laser fees added I'm hoping to fit within ~350 EUR for the machine with the pen,...
Here's the machine actually working! I put together a very simple demo page in Inkscape to make sure there would be no nasty surprises (there were), and I'm ecstatic about the outcome.The first issue was the backlash on the X-axis. As previously mentioned,...
Software: As you can gather from the pictures, the basic algorithm has been implemented and it works well. But it is far from complete. Here I'll describe what I have so far and present the (probably buggy)code to you.An outline, in graphical format...
I put pen to paper just 19 days ago. It has progressed faster than I would have ever dreamed. I would have posted more here but I didn't even know about this until a few days ago.I teach at a residential high school in Arkansas for gifted students. I...
