Reverse Engineering from Package Data
Log from Reverse Engineering a Drone
As you can see airodump-ng picked up the WiFi of the drone and also that it is running on channel 2. Next I recorded some packages. sudo airodump-ng -w JJRC_out -c 2 -bssid 10:A4:BE:2E:77:B5 wlan0mon While recording I simply used all the functions the...

Testing Germanium transistors (2nd part)
Log from Clockwork germanium
Before I can proceed with the debouncing circuit, I have to evaluate the characteristics of the transistors and choose the lousiest (debouncing is not a critical circuit). Fortunately I had built a board for manually Testing Germanium transistors. Remark:...

A basic script to monitor the controller input sent to the quadcopter by UDP
Log from Controlling a JJRC H37 Elfie quad from a PC
I'm in the process of making a small program to read the control input from a USB gamepad and send the commands to the quadcopter but first I wanted to make sure I got the UDP protocol right. Therefore, I wrote a small Python script that can be combined...

2nd Platform Support -- Olimex board
Log from TRS-80 Model 1 on a PIC32
"...O frabjous day! Callooh! Callay!' He chortled in his joy."Today I finished porting the code to the Olimex Duinomite Mini board, so now you can have your emulator for about $25 USD (for what we paid upwards of a couple grand in the day), and soooo...

Outdoor test results and random thoughts
Log from Wireless solar-powered sensor node
I've tested the module outdoor for about two weeks and it works great. Yesterday was the coldest night (-17.8 °C), and it passed without any issues. Additionally, I'll double-check datasheets for each component to validate the temperature range,...

We're crowdfunding!
Log from uECG - small open source wireless ECG sensor
Finally we got to post on Hackaday! We're back from Makerfaire - it's been a very busy time. Lots of people (20+) tested our device in the field, so to say, and ironically, it could be considered a stress testing for our device, though we couldn't measure...

0201 Club
Log from An Unfortunate SMD Project
As the misery spreads, it seems only fitting that we should recognize those who are unfortunate enough to suddenly complete the SMD Challenge. To be included in this club, you must submit photographic evidence (or link thereof) of a working SMD...

Follow me - part 2
Log from Wild Thumper based ROS robot
FInally got a HB9CV antenna, a BNC cable and a corresponding adapter to my RTL-SDR. I've put the antenna onto a servo and 3d printed an adapter, the whole setup looks like this:The beacon was quickly wired on a breadboard. The antenna does not have the...

Xling v3.2 - updated board, PCBWay review and firmware bugs fixed
Log from Xling
Introduction I'm going to include a review for PCBWay service as a part of this update because they supported me with the current iteration of Xling v3.2 and manufactured black PCBs for free.However, I'd like to keep it as fair as possible because everyone...

Long slides that work
Log from A Cheap Compact Linear Slide
long slide runs smoothly all the way out to the end -- where short bearings overlap side-by-side -- and back From the start this project has focused on variations of a single basic design using 100mm rods. Late last year I experimented with reduced...

Some hardware projects based on Karadio
Log from WiFi Webradio on ESP8266 or ESP32
Many pcb projects are in progress to run KaraDio. Dimitris works on a pcb with esp8266, the external ram and the vs1053 with the complete set of option by juumper (a0 and type of ram).I hope he can sell it soon (with mounted components). discover1977...

Test Print Ordered (Updated)
Log from Mac mini 2018 Hexa Core Cooling Analysis
STL files don't translate well over to a machine shop for making prototypes. In my travels, I came across https://print.all3dp.com/. There are probably other, better sites, but this works well enough for what I seem to need. I took the OpenSCAD model,...

First Batch Ready
Log from EikGeiger
I got approached by PCBway who wanted to sponsor a batch of assembled prototypes, and i just received them and fired them up!! I wanted them without the inductor and tube holders because i want to experiment a bit with different tubes, and to check...

To pull or not to pull - that is the question
Log from IuT voltmeter for a breadboard
... which turned to have the following short answer - to pull down with a 680 kOhm resistor. For a detailed answer---------- more ----------we need to acknowledge that a floating input of the ADS1x15 results in a rather high voltage reading. Therefore...
