DuPont Connectors Galore
Log from World's first 32bit Homebrew CPU
One disadvantage of a 32 bit CPU is that your internal and external connections are 32 bits wide. That makes for a lot of wires. So time to start making plenty of cables for working with prototype boards and hooking everything up. Rather than buy them...

Rpi3 EP2C5 FPGA buffer HC-SR04
Log from Ping#
The final goal of this project is to get a LIDAR like scan and show it on a GUI. So naturally it made sense to have an OS in the pipeline. Instead of dealing with USB connection to a PC, I opted for SPI between a rapsberry pi and a cyclone II FPGA. The...

Chasis aquired! Layout begins.
Log from Pyrotechnics sequencer with wireless trigger
I found a used rack mount drawer assembly, 3U. Its plenty big, it's metal for durability and the electronics are completely enclosed when the drawer is closed. All the components in the box will be mounted to the piece of medium density fiberboard,...

Nr. 7 - Major breakthrough!
Log from Effect of moon phase on tombstoning
There was a little pause because we had holidays and went on vacation so I missed the last full moon (20220318), but there are plenty of parts left.Soldered Nr. 7 today - 20220320 - 18:27One resistor (the 360R one) didn't sink into the solder on one...

Enclosure, wooden support and wiring
Log from Air Extractor Controller for AC
Plenty done for this week : Wooden support is almost doneWiring of high voltage wire has been doneJunction box fitted with a DIN rail installedAir extractor has been delivered and mounted Here’s some pictures of the progress

Diagnosing range issues
Log from Radar Sensor
Apparently the IVS-362 should have a range of 20m, so something is wrong!These are some oscilloscope screenshots with the signal generator set to 200Hz with a voltage amplitude of 2.7 volts:Channel IF1:Channel IF2:These readings were taken in a cluttered...

All systems are nominal
Log from LoRa darkStar
Finally, the timer chip and associated logic gates are working at all time intervals right across the full range. The timer and logic circuit is shown in the photo above and occupies a footprint of 20 x 15 mm. There's plenty of opportunity for a bit...

Frame
Log from SNOWBYTE
The frame is made with aluminum linear rails cut to the following dimensions. This offers plenty of space for housing all the electronics like the motors, powersupply and the microcontroller+control circuits. I also picked such dimensions because...

Experiments in Wheels: Part 3
Log from Micro Robots for Education
Hello, once again I am here to talk about wheels, don't worry, next time will be something different, but for now, it is wheels. First the video, because hell why not:The wheels that I have settled on are made with a DLP driven, resin curing 3D printer....

Hypocycloidal gear with timing belts?
Log from Strain Wave Gear with Timing Belts
Is this the next logical step? I was surprised by the torque efficiency of the hypocycloidal gear I made in the Hesitation, Repetition and Deviation log, so perhaps it's worth pursuing for a bit. Until today, in conversation with @Dan Royer I...

1) Mechanics
Log from Scribing Robot
SHOULDER and ELBOW The 2 main articulations (shoulder and elbow) are equipped with stepper motors. The transmission uses toothed belts and their pulleys. These 2 articulations are very rigid. They are made with 3mm aluminium sheet, and braces made with...

Transmission test
Log from FilaMecanum
Ran into some issues with my transmission. After assembly and during some initial testing it became obvious something was amiss. Well, a couple things. First it was loud. Way louder than the original. This was traced down to a...

Minty Fresh Breakout PCB!
Log from VISP - Ventilator Inline Sensor Package
Even though I ordered "Super Swift" boards from @oshpark, they are going to take a while to get here, and we have questions we need to answer, now. The barometric sensors we chose have pads that are simply far too small to air-wire them, without a microscope...

PC board etching pliers
Log from How lions etch PC boards
These PC board etching pliers should make the process a lot easier & allow bigger boards. They were based on the size of normal scissors to keep the operator's paws away from the chemicals. The range of the slider motion & the size of the largest...

Motorized Caster
Log from VR Locomotion Concepts
I had an idea for a motorized caster yesterday and spent some time making a model of it. Up until now I haven't found a motorized caster or thought of one that I think would be small enough and powerful enough for a VR shoe. But this one might be.It's...
