$100 DIY Car Computer

at 11:31 pm. Filed under Complex Hacks, Computer Hacks, Cool Gadgets, DIY Hacks


If you need some computing power on the go you might want to look into adding a car computer. Sentdex shows us how he does it on the cheap, the top of the great find is the $17 monitor. It has a Raspberry Pi as the heart, an ODB interface and a camera to loop record. An interesting power management system allows the system to detect when car power has been switched off and gracefully shut down the system.

U.S. Navy Autonomous Swarm Robot Boat

at 11:25 pm. Filed under Computer Hacks, Insane Equipment

U.S. Navy Autonomous Swarm Robot Boat


The U.S. Navy is developing Autonomous Swarm Robot Boats. These boats are outfitted with Control Architecture for Robotic Agent Command and Sensing (CARACaS), this technology was developed by NASA for the Mars rover. 

“Navy researchers installed the system on regular 7-foot and 11-foot boats and put them through a series of exercises designed to test behaviors such as escort and swarming attack. The boats escorted a manned Navy ship before breaking off to encircle a vessel acting as a possible intruder. The five autonomous boats then formed a protective line between the intruder and the ship they were protecting.”

Inside the Commodore PET

at 1:28 pm. Filed under Computer Hacks


David Watts got his hands on a Commodore Pet computer. I have never seen under the hood before, and it is quite funny that the case actually opens like a hood on a car including the prop stick to keep it open. David will be attempting to restore the PET so that it works properly again, it looks like the keyboard didn’t stand the test of time very well, there are now more keys not working than working. I am curious what will be needed to bring it back to a fully functional state. I am thinking the caps are long dried out and not doing much smoothing anymore.

Arduino GSM Home Automation System

Arduino Home Automation System


Timofte Andrei shows us how he built his Arduino Home Automation System. The video below is in Romanian but with the English Instructable and video overview you can get a good idea of what is going on. He has went all out and built an Arduino clone for the brain of the system.

 “For this project I’ve used:

1. An Arduino clone
3. Relay module
4. 2×16 LCD Display
5. DS18B20 temperature sensor
6. Push button
7. Some Dupont wires
8. A led module (this is optional, if you have a chinese relay module with built in LEDs)
9. Some nuts and bolts to mount everything in place
10. A wooden chopping board or other kind of wooden board for propper display of the components”

Adware Driving Me Crazy

at 4:52 am. Filed under Computer Hacks



These days people who design circuits usually do so on a computer, the days of pencil and paper are almost all but gone. The issue is that your computer is probably working harder on useless background tasks than it is running your design software. We will go through some of the things to take back control of your computer so you can get some productive work done rather and hopefully avoid a few coupon popups and browser toolbars.

In the video I mentioned that I was installing a piece of software that I had ensured was genuine. Turns out that there is a bit of a twist there also, I needed a piece of software that would allow me to determine the color of any pixel displayed on my computer. My need specifically was to determine the actual color of a background of a website. I had used this type of software in the past but could not remember the name. I did a search and came up with a site that was doing some reviews of this type of software. I selected Just Color Picker by Anny Studio to try out. You can see in the screen capture below that as I scrolled down the page I accidentally clicked on a Google Ad that took me to an install page for Image Editor with the familiar download button. At the bottom of the Image Editor page you can see that they mention that there is some bundled software with their product. At this point I am still angry, at myself for not seeing that this was a Google Ad that I clicked on, at Anny Studio for placing Google Ads on the page (can’t say much with this though since I also run Google Ads), at Google for allowing deceptive ads to be run in this way and at the company behind Image Editor who is clogging up peoples computers with adware just to make a buck.

Now just because I was tricked into installing this software don’t put your guard down, this might have had the most occurrences of adware that I have ever seen but you can typically find 2 to 4 of these pieces of software being snuck into many legitimate installations of software.


If someone just clicked next on each of the items this is a list of the software that would have been conveniently installed for them.

  • My Search Dial
  • Webget
  • Find Coupons
  • Linkey
  • My PC Backup
  • RegClean Pro
  • Optimizer Pro
  • Discover PC Cleaner
  • Price Meter


So how do you see what is slowing down your computer and what can you do about it?

  • Go through the Add Remove Programs in your Windows Control Panel and uninstall everything that you will never use again and have a good look for programs that got snuck in here without your knowledge.
  • Look at all of the programs in your Windows tray, things such as Skype might not be needed to start automatically. A Windows program called Autoruns can help you determine everything that is starting up automatically so you can make the decision what you would like to launch only when you need it. Of course you can still use the tried and true MSCONFIG by typing that into the run dialog.
  • Remove useless toolbars that have been installed into your browser (Firefox, Internet Explorer, etc)


Hopefully some of these tips ads a bit of productivity to your day and takes away from some of your slow computer frustration.

Fluke 196B Handheld ScopeMeter Repair

at 1:37 pm. Filed under Computer Hacks, Electronic Hacks


Over at The Signal Path Blog  Shahriar Shahramian has a look at a Fluke 196B Handheld ScopeMeter that he purchased from an eBay seller. The meter was purchased for a few hundred dollars and was listed with a fault that is doesn’t power up. It didn’t come with probes, a back cover or the battery. Shahriar was ready for a full tear down and hopefully a repair but as it turns out the meter worked just fine! Not sure how cheap these surplus dealers get some of these test gear lots but I am guessing it is pennies on the dollar of operational value and they just sell them as non working because they can’t be bothered (or don’t have the capability) of performing any functional testing. Good thing is we get to see a full tear down of the meter along the way. At 32:40 you can see an interesting method of chip cooling and shielding that fluke has used in this unit. This thing is built very well as you would imagine for the price point and the fact that it is a Fluke.

Car Computer Build

Car Computer Build


Even the most modern cars (except possibly ones made by Tesla) don’t provide much computing power that the user can harness. EEVBlog user Ptodorov wanted to have the power of a mini computer in his car. Only thing is a computer doesn’t interface with real world things like door switches and turn signals very well. To interface with the car hardware an Arduino and a relay module was used. Things haven’t been all smooth sailing though since the system has gone haywire while driving and the system does draw a bit too much current when off but it is a great start and inspiration.

“For the last 5-6 months everything ran fairly smoothly with a few glitches and bugs. But a few weeks ago all hell broke loose
while I was driving. Suddenly left and right blinkers started flashing, the headlights started blinking and doors kept locking and unlocking.
This kept happening for a good 30 seconds. Fortunately there were no other cars around me. Also when the winter came the arduino started draining the battery more noticeably, after leaving the car for several days it didn’t start with the first turn of the key even trough I’m putting the MCU in sleep and waking it on an interrupt from the remote control. The battery drain was 250mA and after I disconnected everything I’ve done from the car it drop down to 120mA.”
