KIT1 iterations
Log from Open Source IOT Platform
Developing the KIT1 raised several problems in hardware and software, and those were solved with multiple PCB iterations.These are just of the few that were built. Initially, v1.0 used a ferrite transformer for the High Voltage inverter needed to boost...

Zytek hardware
Log from Hacking the Zytek 55kW EV drivetrain
Since this is the first project log, I'll 'briefly' go over the motor and driver as I tear it down.With the inverter lid popped off it's a bit clearer where the actual motor is. (it's smaller than the inverter!!)in that picture I've already removed the...

Raspberry Pi Pico & RP2040: Things You Should Know
Hacker page by UCTRONICS
Here’s everything you need to know about the new board and the RP2040 chip. The official release video: How much does the Raspberry Pi Pico cost? The RPi foundation priced it at 4 US dollars (around £2.9)! How much does the RP2040 chip cost?...

Generalised fault injection
Log from VHDL library for gate-level verification
Christos has modified the original DFF gates to inject faults and evaluate/validate the fault-tolerant memory cells used by the CERN. Meanwhile, I created this library to help with ASIC design, which is a different beast and methodology. I have no bit-flip...

New Skill Acquired: Plasma Cutter
Log from The Village
Earlier this week, I spent about 15 hours with the cutting torch. Just hacking apart a massive railroad dump truck I'm rebuilding. Hacking away at the truck, burning myself with slag and splatters, and leaving behind some truly hideous cuts as the torch...

Caption CERN Contest Week 22 Winner
Log from Caption CERN Contest
The tangled web woven by Week 22 of the Caption CERN Contest has come to a close. It's been another bumper week with 112 comments. Thank you to everyone who submitted a caption! We realize it may have been hard for some of the network engineers out there...

First, play around with an already built one
Log from Do a Real Magic Spell: "Essdeeaar!"
Get an SDRA good example for a cheap SDR receiver is an RTL-SDR TV USB dongle. RTL-SDR was designed as a TV tuner for PCs. It can be plugged into a USB port, and with it's software installed it can receive FM radio stations or TV programs.But with a...

Walking the dog.
Log from Arcus-3D-C1 - Cable 3D printer
I'm a fan of the Beaglebone. You can get down and dirty with hard-realtime assembly level control of pins if I you want, or watch from 10k feet and twiddle a pin in web browser with just Javascript.I sum up the Beaglebone Black to people who...

Robust linear actuator
Details from Robust linear actuator
The actuator consists of both bought mechanics and 3D printed parts - printed at 0.2mm layer in PLA with 40% infill. Tested to be strong enough to not break under loads of 12 kg. I haven't really made other high load tests other than lifting the 12 kg...

Nozzle presets
Log from Apartment ventilation system
Positioning the nozzle by IR remote has grown into a pain in the mane. It would be money to have 3 preset positions. The mane problem with presets was supporting 5 more remote control buttons. The clockspeed had to be stepped up to...

Software: Setting Up The Preview Screen
Log from Raspberry Camcorder and Video Editing Station
I started with my best guess at the easiest way to implement this, and it failed nicely. The goal is to get a preview up as soon as the program starts, and try to keep it running the entire time. I added all the stopping and starting as I know the different...

Steering actuation
Instructions from Quad-ROS-bot
The installation of the steering actuator is shown below, it's a thumping great 4000 N device capable of tearing the whole machine apart if not careful. The actuator needs to be able to turn slightly at each end and so is mounted on the stainless steel...

People I look up to in the Retrobrew Community
Log from ONAN 1111
As you may have guessed, my all time favorite is Bill Buzbee and his Magic 1 TTL 16-bit 70s style homebrew minicomputer. He is no doubt my greatest inspiration and his example is the chief reason I decided to go ahead with my own project. However, Bill...

Graphics, retrostyle.
Log from Keplermatik
As I’ve been developing this satellite tracking console, the goal has been to create a really unique piece of hardware that does useful work. The fact that it’s built up from a very eclectic collection of parts is pretty important to the aesthetic, so...

Merging C and ASM...
Log from Z80 Reverse-Engineering And Hacking Adventures
Next-Next and Next-day brief Updates at the end... ... I am by no means experienced nor knowledgeable in this realm... I have done a bit of inline asm in my otherwise avr-gcc progects. But this is very different. Here we have a booting system written...
