Background If you have been following Hackaday for a while, you will have seen on numerous occasions the KENBAK-1, regarded by many as the first commercial personal computer. Ten years ago Mark Wilson introduced KENBAK-uino, a reproduction...
Couldn't take a picture with my phone. The screen showed white block where the text should be. Their scroller example from https://hackaday.io/project/161859-2018-hackaday-superconference-badge/log/154558-basic-program-examples looks like:...
Control the classic General Instrument SP0256-AL2 speech chip and AY-3-8910 sound generator with a Raspberry Pi and this Python library. The SP0256-AL2 was originally available in the early 1980s in speech add-ons for the VIC-20, Atari 8-bit computers,...
I did a quick test with a laptop(Putty) and Arduino in the vehicle and was able to to get OBD info, so I guess the connections are fine. And the 1996 Ram even started afterwards. I added some new handling for 'SEARCHING...' after this. Looks like there's...
VCF-80 Model 100A modern revision of the Tandy TRS-80 It is a popular trend among makers to re-purpose old electronics as housings for modern single-board computers. Many call them “cyberdecks,” based on William Gibson’s concept of a portable...
Programmer Design OptionsStrip-board works well (I use A$8 41 x 144 board), but I did look at using a mini-Mega2560: I used an on-board Arduino Nano as they are cheap (and I have a couple of them lying around) and they provide serial and power.But...
Currently in diy controllers (like renard SS16) and equivalent wired controller costs $80 with shopping around. Then to make it wireless requires an additional $10-30 depending on what you chose.That is still a bargain compared to commercial controllers...
Briefly about architecture and instruction set - it is 8-bit design with 8 registers: 000 - 0 (always zero) 001 - A (accumulator) 010 - B 011 - C 100 - D 101 - E 110 - F (flags and 3 higher bits for jumps) 111 - G (8 lower bits of program counter) Flags...
I made some radar projects using simple HC-SR-04 ultrasonic sensor. These are very basic ultrasonic sensor work on a carrier frequency of 40khz. There are 4 pins, 2 for the power and other two for the echo and trigger. But I want to use this sensor underwater...
Overview At the beginning the antenna is directly connected to the AD9226 Analog to digital converter, sampling at 64MHz. The 64MHz clock is generated by the FPGA, so that it can sample it well (more on this later) Please note there's no external PC...
In preparation for opening the Supplyframe Design Lab in Pasadena, we've been holding semi-regular meetups and other events for just over a year. The idea was to get to know local hackers and makers, plus engineering startups and business.We've made...
The shiny new Design Lab is not quite totally tooled up yet, but we know some of you have been waiting really patiently to check it out. We've literally just got the paperwork sorted to have people in the space, so come on in!We'll be hosting a meetup...
The idea is to build a 80cm x 80cm backlit picture frame that's look like a Polaroid print. The main structure is in wood and milled to The front is in PMMA The edges in Acrylic laser cut - tactile switch - size 80 cm x 80 cm ...
