Well first of all happy new year to all! … Today marks the start of a new journey for me, I quit my last job in September last year, I needed a change something new, over the last three months I’ve been gathering all the tools to upcycle old objects, make old new again etc. I’ll hopefully get chance to start incorporating bigger projects in the vblog and you lot will see my mini workshop! Still have a lot of work to do, I’ll write another blog when I have some free time. Once again happy new year and have fun hacking!
Hey you guys!! So a quick catch up, new tools installed in the garage ready for the new year, awaiting some blasting medium for my cabinet and I can finally get started. The reddit arduino / pi project is finished including checksums and far less glitchy code. I made some really stupid mistakes the first time round but it’s all a learning process. I’d kinda hoped I could just grab the checksum code, copy, paste and be done but I must have spent maybe 20-30 hours debugging, refining and analysing.
Next on the agenda is the clock I’ve been working on having issues loosing time have done a fair amount of reading on the module im using and think i’ve tracked down what the issue is, we shall see though, when I get some time to sit down and start coding.
Love my workshop at the moment too still needs some more work but it’s nice walking in to a tidy place to work with plenty of space. That said there’s still a hand glider hanging up in there which I’m thinking I probably need to get rid of b/c of space … yet its never been out of the bag since I bought it.
Anyway I’m waffling, have a great Christmas and new year etc. I shall see you on the other side. Hack all the things, drink all the tea, eat all the mince pies, read all the manuals, scan all the frequencies, log all the voltages and be safe!!
I have my lounge back in order now, have moved the unit to my landing, still not tested but everything is ready to go just waiting for a couple of friends to come and help me move it downstairs. Oh and its Friday so im going to take a few hours off from the hacking spree.
Running on minimal sleep. Waiting for two deliveries at separate addresses on the same day … chaos! Coffee in hand, weather is still terrible. Starting to write up reddit python project notes.
Had a nice early night last night. Woke up spark awake at 5.30 and couldn’t get back to sleep. So decided to make some breakfast have a brew. Loads to do, as you lot may know we’ve had some pretty bad storms in the UK recently and the weather has been particularly crap for this reason I’m avoiding sorting my garage out till it cheers up a little. I’ve got loads of little micro controller projects on the go just trying to condense what I’m learning into some useful videos / code. I’ll probably write up all the notes for the RPi reddit project later on today too with photo’s etc. Right peace BBL
Well hakology need to record a VBLOG later had some new tech arrive, nothing too special, a new microcontroller (the smallest one yet), some adapters and a couple of transistors I need for an RF amplifier I’m looking at building. Need to go and get cleaned up though before I get messy, starting to grow one of those linux admin beards.
Managed to get the arduino mini programmed using another arduino. Having issues trying to get the two boards working in unison the display draws, but I can’t seem to get the time from the RTC.
Up bright and early this morning covered almost head to toe in fibre glass insulation. Rearranging the loft to start putting some temporary flooring up there. Also want to reposition my discone and dig through some of the old tech. I was thinking about trying to pull my old acorn electron down and making a short vblog on it see if I could power it up etc … 1985 vintage … 26 year old capacitors hmmmm ? 🙂
Six hours later and I’ve used all the floor boards I have. Still a long way to go but its a start. Completely knackered going to have a rest and contemplate my next job.
Time to get busy NO MATTER WHAT. Had a great weekend spent with my son and family, we even did a little coding using the reddit API. Sunday was cool too, I managed to grab some bargains from a few second hand sales, nothing exciting or tech related, just a few books on survival/bushcraft/scouting. Today im going to attempt to record the SDR# video as the last time I forgot to hit record! (*not quite I forgot to hit record but that’s another story/rant), I’m also ready to go war driving so that might be a thing in a few hours. Had some more breakout / dev boards turn up in the post but not the one I’m waiting for, lol, its always the way.
Nothing ever goes as planned, I went for a little war drive earlier after having installed kismet, gpsd-clients and gpsd. Recently I reinstalled debian with lxde and I couldn’t figure out, or seem to kill the gpsd process to set my gps as the default device (/dev/ttyUSB0), no matter what I did couldn’t get kismet to detect the dongle in gpsd or even find the configuration file. I decided to run kismet with the –use–nmea option BUT this was a lot less reliable in kismet than what gpsd usually is. Then my netbook went to sleep as I havent figured out the power saving settings in lxde yet. (I’ve been using lxde less than a week) I pulled over to restart my scan but accidentally chose the wrong wireless device when I restarted kismet, so all in all a complete mess. That said I’m working on a little script to load everything at once correctly so this won’t happen again. I really newb’d out tonight, If at first you don’t succeed try harder.
sudo kismet -c wlan1 -use-nmea-gps /dev/ttyUSB0 -gps-reconnect true
DO NOT USE THIS FOR GPS IT SUCKS … I had the most sketchy log files using this syntax to call kismet. Might have been the way I had the dongle positioned but I think its the way netxmltokml process the file when its been generated using that switch.
Good afternoon hakologists, I’ve finally got the LED matrix ‘working’ I’ve managed to find one library that draws correctly to the screen, with a little bit of effort I think I could rewrite it for multiple matrices. Today I’m going to get a quick vblog together then later tonight hopefully record the SDR# video. Then we’ll take a look at multimon-ng and demodulating pager messages.
Need to send a massive shout out to gir, for sending hakology 2 RPi Zeros from the US as I couldnt get any at a reasonable price anywhere in the UK. Ridiculous considering they are made less than 50/60 miles from my house.
Family stuff over, vblog recorded, introduction video for vblog channel recorded, vblog rendering, time to get the kettle on and make a brew, thinking I might have a look at an old netgear router I have, see if I can connect using those new USB2UART boards. If I’m feeling really productive I might even get the sdr# video done.
Reflecting on the weekend, have been working on a few projects. One using the max7219 LED matrix driver, which I’m considering writing my own library for as everything i’ve tried seems to fail, I have it working and can address each LED individually but haven’t been able display anything useful ie. fonts or text effects … anyway that’s a work in progress. I turned my hand to configuring a small 1.3″ OLED screen someone donated a while back now I can see it was some kind of addressing issue in the code I initially got it running (there were 2 pixels columns on the far right filled with random bits and a couple of leading pixel columns missing) anyway its working now I noticed the version I was running was from the google code repo and checked github see if the project was still live and found some more recent libraries, installed those and that seems to have remedied the problem.
Managed to sort out a good method for screen capture in gnome3 debian jessie. Was having issues capturing the screen in a format I was able to get in to my editing suite. Inadvertently I found out that debian jessie has built in screencapture/screencast ability. Pressing shift+ctrl+alt+R, a small red dot will appear in a panel near your login/logout panel to show if you are recording, files are automatically saved to your home videos folder, to stop recording just hit the keyboard shortcut again.
These files happen to be in webm format, I havent yet tried running the webm files through handbrake to see if I can convert them to mp4 as my editing suite doesnt natively support webm and one huge problem with the built in screencast is it only records my desktop and no audio. (Maybe I’m doing something wrong, would be easier to just use the built in screencapture)
So eventually my final solution was to record using kazam to mp4, this captured the video + audio, was even hoping I wouldnt have to transcode it again, but still the default format output by kazam isnt compatible with vegas, I then ran the files through handbrake and imported them and everything seems ok … now all the audio syncs with the video perfectly.
Its a bit of a mess/bodge job but it works, maybe if I get some time in future I might have a look see if its possible to edit the default screencast settings to capture audio+video and output to a compatible format preferably mp4.
NB. The default screen recorder only allows you to record for 30 seconds use the following line in terminal to change the maximum record time.
gsettings set org.gnome.settings-daemon.plugins.media-keys max-screencast-length 45
Nice hot brew and to call my ISP and figure out why their automated system hasnt automated adding and configuring the website I registered yesterday, meh, I bet the support line isnt open till 9.
So I logged a ticket earlier, checked back at 11 for an update, but nothing. In the process though I found a bug on my ISPs management interface and have just reported it. Nothing like a good vulnerability to start the day. Think they’ll sort the hosting out this afternoon. 🙂
Just getting some advice on responsible disclosure from the 2600 bunch. Cant wait to do a little write up on what exactly was happening and how I came across it. A little bit gutted they don’t have an active bug bounty program.
Well fun over for the morning, back to preparing notes and research. I say research … I’m currently working on some game hacking lol which might involve some impromptu gaming. All the notes for the next hakology video are ready, looking for some new projects and interesting stuff for you lot.
Pic of the day today goes to … one of my old processors I’m trying to find my old DX33 but this is the oldest one I could find for the moment. 133Mhz of joy back in the day.
HACKS!!!! Hacks a plenty today. Just hacked my first game oh yea! Working on something that’s not been looked at before which is also fun 😀
In case you were wondering.
Enjoying a coffee and reflecting on the day.
