Ping Latency: 203 Days

It happened again, Pointless Circuits disappeared from the interwebs. Again the server was gone without prior notice. Then life happened and it took more than six months for us to get the site back online. We’re sorry for any inconvenience this caused.

Pointless Circuits is now hosted on a more costly German VPS. We hope that reduces the risk of similar outtakes in the future.

Pointless Circuits Is Back Online!

Yesterday we found out that Pointless Circuits had been down for 15 days. It seems we trusted our hosting provider too much. Everything was fine until suddenly our accounts were gone, as were the servers.

We’ve set up a new server (with a new hosting provider!) and will keep working to make sure such a major outtake won’t happen again.

GoT Lamp Update

No Project is ever perfect, and when doing many things the first time in a single project, you have to fine-tune and improve multiple things. So, after admiring my stunning handiwork, I slowly started realizing many faults.

Soldering Exercise: Hardwiring a microSD Card

For a very cheap hard drive extension, I decided to fit a 32gb microSD card into my Acer C720(p) Chromebook. As there exists no microSD to SD adapter short enough to not stick out of the Chromebook’s card slot, the only option I had was hardwiring the card. (I could obviously have bought a bigger M.2 SSD, but that would have been more expensive and well, where’s the fun in that?)

An Online AVR Bootloader Generator

When finishing the air dehumidifier project, I first came into contact with FastBoot, a serial bootloader for AVR controllers with lots of cool features. It was quite a hassle to compile, so I set out to create an online tool to do just that. For anyone who doesn’t want worry much when in need of a firmware to program AVRs over uart: Meet fastboot-generator!

Revival of an Air Dehumidifier

Months ago I got my hands on a faulty air dehumidifier. The output on the display didn’t make sense and it wouldn’t take any user input, let alone start running. It was given to me at no charge and I thought it might be an interesting project to repair the device.

Winter Is Coming - and We Need Light for That!

On the continent of westeros, a pretty bored guy was once surfing his favourite waste-your-time webpage, when he suddenly found something he liked, and wanted to posess. And so he engaged in the Game Of Thrones, where you win or you die. Or in this instant, build it or fail.

Natoblaster Part 4 - Lasercut That Stuff!

New update! After getting access to an industrial grade lasercutter, we decided to remodel the whole control plate and speaker arrangement. Working with a lasercutter the first time proved to be even easier than expected, simplifying our work massivly!

Natoblaster Part 3 - Voltage Supply and LED-PWM

After a long time, a new post with an Update to the Natoblaster. After the casing is finished and the necessary Parts have arrived, it is now time to finish some of the innards of the device. For the amplifier itself, we will go for a off-the-shelf device, the voltage supply and PWM for the RGB-Leds will be homemade.
