The conventional way of doing this is to use the command md to dump the firmware bytes as text characters to the terminal, pipe to a text file, and run a script to convert from ASCII to binary. Unfortunately, this process is very slow, I calculated that...
Announcing a major new capability: CylinDraw makes for an excellent paper plotter! The hardware needed to enable this capability only requires the addition of a large tube to wrap the paper around and two rubber bands to secure the paper in place....
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...
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...
We thought you might be interested in knowing the mechanics and math involved in four stage arm control. Its quite simple really. We hope this will help a few new hackers with their future builds. Here we go...The aim of this algorithm is to determine...
RTM, RTP and RTU tips Weller this year introduced new series of RT tips with nice slogan "No compromise". There are three types: RTM - RT Micro - they are same like previous line RT, but with new namingRTP - RT Pico - these tips are smaller, shorter...
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...
Despite having the ability to theoretically, I've never done true Z stacking by combining images. The other uses of Z height change was to pick between focused images, not actually combine them. This works okay when the change in height is across different...
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'm working on some code to generate spiral patterns. So far I'm using Turtle in Python to simulate the pen plotter (you may remember this from the Apple ][)from turtle import * stylus = Turtle() #stylus.setpos(100,100) def drawSpiral(turtleObj,limit,...
I'm happy with the output right now. I thought the right-hand motor was slipping / behaving inconsistently, but I've re-done the GPIO connections and I think one of those may have been loose previously. One thing I don't yet have fully worked out...
It all started when I encountered that old white Brother AX-110 electronic typewriter. The daisy wheel was broken so I decided to crack it open and see what‘s inside.Surprisingly, there was not much inside: Just a little circuit board with a microcontroller,...
Check Out @johnowhitaker's new project: #Mini PCB printer, which describes a technique to laser-melt toner directly onto copper-clad board!If you haven't seen it already, a while-back @johnowhitaker came up with a technique to laser-melt toner directly...
If you haven't seen it already, over at #CD/DVD mechanisms and cartesian thinggie[s?] @johnowhitaker came up with a technique to laser-melt toner directly onto materials such as copper-clad board! (That description and link will likely become a bit redundant,...
