Details about some components:AC/DC ConverterThe AC/DC converter is made by Hi-Link and the model is HLK-PM01. This component is perfect for this project because it is really small and cheap. It supplies 5V/600mA from 130VAC or 240VAC. It is plenty of...
Construction The computer is divided in two seperate boards. First there is the mainboard. This is the upper PCB that carries the Compute module 4. The board handles the high-speed interfaces and carries the USB 3.0 host controller, the USB 2.0...
Programmer Design OptionsStrip-board works well (I use A$8 41 x 144 board), but I did look at using a mini-Mega2560: I used an on-board Arduino Nano as they are cheap (and I have a couple of them lying around) and they provide serial and power.But...
Techniques ReviewWe are going to consider only time series analysis in this section. There are reviews of "complexity measures" (Feldman and Crutchfield 1998, Daw, et.al. 2002). Kuusela, et.al. (2002) compare the results of ten different complexity measures...
ESP8266 PCXT Emulator Build Notes Note: This has been made 100% functional by WS, project at: https://hackaday.io/project/183023-esp8266-pc-xt-emulator WS's code works, and I will probably not be going further on any development here. I may attempt...
I have found the SmartResponse-XE an interesting "Arduino-compatible" device. With BASIC installed and the added "Q" token (alias for PRINT) to allow realtime evaluation of simple math. However, the math functions of "+", "-", "/", "*" all...
Please check out the Github for all future updates: https://github.com/lambdamikel/picoram6116 A follow-up to my 2114 SRAM Emulator. This time I am targeting the 6116 SRAM chip - full 2 KBs and a serious CPU at full speed (i.e., Z80 @ 1.8...
From Wikipedia, the free encyclopedia: A medical tricorder is a handheld portable scanning device to be used by consumers to self-diagnose medical conditions within seconds and take basic vital measurements. The word "tricorder" is an abbreviation of...
basic code for using - updates later/* MIDI note player This sketch shows how to use the serial transmit pin (pin 1) to send MIDI note data. If this circuit is connected to a MIDI synth, it will play the notes F#-0 (0x1E) to F#-5 (0x5A) in sequence....
This is a modular x64 mini pc/ smart phone im putting together instead of buying a new handset. i dont care much if its thick, so deal with it. Parts: 5" regular screen: 50$(the 5" version) https://www.amazon.com/OSOYOO-Portable-Raspberry-Compatible-Raspbain/dp/B07KKB5YS9/ref=redir_mobile_desktop?ie=UTF8&ref=ppx_pop_mob_b_asin_title&th=1...
First of all, to elicit assiduous gas measuring results, I chose to utilize these MQ series gas sensors by connecting them to the Arduino Nano: MQ-2MQ-3MQ-4MQ-6MQ-9 After choosing gas sensors for my device, I decided to control its settings and features...
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...
I bought a bunch of Z80 parts on ebay for cheap ($10 plus shipping). The parts came on a PCB which had not yet been flow soldered. From the date codes of the parts it looks like it was stuffed sometime around 1999. All I had to do was straighten...
Edwards EXT255H turbo molecular pump controller BackgroundI have recently taken an interest in high-vacuum systems. A TMP is the bridge between the relatively soft-vacuums produced by traditional mechanical pumping systems and the high-vacuum world or...
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,...
