Reprogramming Without Soldering
Log from Motor Shield Reprogramming
Turns out that the procedure in the previous log can be greatly simplified. You don't need an ST-Link programmer, and you don't need to solder anything. Even if your shield is locked, you can unlock and program it with a simple serial adapter. Here is...

USB Serial Uart
Details from USB Serial Uart
Around the same time I started this project I also started to dive in to Kicad. This was a new pcb software for me. I have heard about it in passing but up to this point have not tried it. For this board I decided to change that and go ahead and design...

Log from Advantest r4131 AFC
The first mixer in spectrum analyzer is the one responsible for center frequency of analyzis and frequency sweeping. In advantest r4131c it is not any different. The main part responsible for correct frequency readout is controller of first local oscillator.In...

VK - LED Bar Graphs
Log from Voight-Kampff Machine
Light Bar Above Main ScreenFor this bar graph I'm currently using 12 - 2x5mm rectangular LED's (I used Red/Green LED's that have 3 leads - common cathode, 2 anodes 1 for each color). I was thinking to make a more graded display (2 levels for each LED...

Another screen
Log from PolaPi-Zero
As said, the memory LCD choice was mainly because it was already lying on a box somewhere in the possibly-will-be-useful pile of stuff. However it's not easy to find and not easy to solder.I had a bit of time to quickly test what could be the result...

A summary of almost a year
Log from Scientific Calculator
I started this project in February of 2016, but it hasn't been a continuous work, here is a summary:The first problem I encountered making the calculator was obviously the parsing. Being unable to come up with a solution, a quick Google search led me...

Some Outrageous Bending
Log from Cardware
Snake Hips again These should now be functional but still need joining to something. To give the system a bit of swagger I've decided to cant the hips out a little way to emulate human hip motion better. That familiar shape at the top of the femur is...

Sensor and Cable Management
Log from SpiderWing
I'm slowly porting all my robot code to CircuitPython for the little crab robot, and I got as far as body kinematics before I ran out of memory on the Feather M0, so next step is some optimizations.I also decided to put a distance sensor on this little...

AL3050 LED Driver (for a torchlight)
Details from AL3050 LED Driver (for a torchlight)
CircuitThere isn't that much to say about the circuit itself as the AL3050 makes things so simple - I just followed the schematic provided in the datasheet . The AL3050 has an internal MOSFET and internal diode, so very few components are needed - an...

Um'ing and Ar'ing
Log from Retro rack and backplane computer
Connector - what to choose? I was trying to decide between an 80 pin header (top left) or a 50 pin IDC style socket (top right). And a SMT (header bottom left) or a through-hole header (bottom right). It seems that the options are not as diverse as I...

Details from DIY Objective 2 Headphone Amp
This amp was designed by NwAvGuy back in 2011 and has since been a staple of the high end headphone community. NwAvGuy released all of the plans for free under on his website. So, if you are interested in building on yourself I recommend you take a look...

5th week
Log from Braille Clock/Watch
Today the fablab received motors ... but the wrong ones. Indeed, they received the continuous servo motors we wanted to order at the beginning but the stepper motors we ordered last week aren't there yet. So, for the moment you can discover how our prototype...

February 24, 2012 - It's Alive!
Log from Project Precision
It's alive! I finally invent something that works! -- Dr Emmett BrownWell, I have just built an honest to goodness Arduino, a round one connected to the most elaborate Charlieplex I have ever heard of... but no light on D13, so I can't even test it with...
