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
Hello hakologists, sorry the posts have been a little thin on the ground currently in the process of starting a new company and managing my existing customers. I’m having some new tools fitted in my workshop which has taken up a lot of time recently. I’m still working on bits and bobs when I have time as soon as I get chance I’ll get something uploaded.
Started installing debian on my main rig.
I thought I’d finally shook this cold, seems to have moved on to my chest, in between coughing and blowing my nose will try and get some more recording done today. I hate being ill. On the plus side I got that website up and running.
Spent the last five or so hours preparing to record and tidying up. When I said chores done didn’t realise everything else I’d got left to do would take so long but its always the way I suppose. Knocked out a load of jobs that needed doing, still having some issues with the website I’m trying to setup but I’m sure its just me being a newb. Have a friend coming over for a couple of hours and that will leave me with the rest of the evening to finish off the latest video.
Some bargains I managed to grab yesterday … 9 books in total for £1.50 not bad when you consider these would have cost over £200 to buy when new. Old but always interesting looking at concepts, examples and principles.
Have made good progress recording the latest video need to divert some time to some RL development will be back online a little later.
Got a little carried away working on that website, back to recording later today.
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 😀 https://en.wikipedia.org/wiki/ToeJam_%26_Earl In case you were wondering.
Enjoying a coffee and reflecting on the day.
