    Code to control output On and Off pulse times with pots

    I never got my head around generating PWM to drive a full bridged output. I tried, but failed. In the end I built my 240V AC 50Hz to 240V AC 25Hz - 250Hz frequency inverter using a full hardware solution. No processors at all. Great fun was had in the development stages. A lot of FETs were...

    20M2 MQTT node with ESP8266 ESP-01 running Annex (and PCB)

    I'd suggest JLCPCB. Five boards, $2 if the board size is under 100mm x 100mm. Fifty boards of around 60mm x 80mm cost me $30 or so plus another $30 (ish) for express shipping and UK import duties.

    Audio recorder module needed, any ideas ?

    Not sure if this idea has been shelved, but... Whilst browsing a very popular Chinese Online Marketplace, I saw that there are a lot of ISD1760 modules available. These can record, and playback. The playback and recording of the ISD1760 can be controlled using an SPI interface meaning it could...

    Audio recorder module needed, any ideas ?

    The ISD1932 can hold a number of tracks. It seems to be out of stock at SparkFun, but you might find stock somewhere? It has the ability to trigger direct playback of specific tracks too. Someone made a "magic 8 ball" with a PicAxe which may be detailed on this forum?

    Audio recorder module needed, any ideas ?

    Try this: http://www.vlsi.fi/en/products/vsmd301.html These can record to internal memory or (potentially) uSD cards. They are programmable, have a free IDE for writing those programs (in a "C" type language from memory) and are about the size of an arduino Nano 42mm x 19mm (approx). They are...

    Programming Editor for MAC ?

    You are right, I wasn't specific in my statement. I don't doubt that the Visual Studio Code works correctly. I would worry about whether the command line compilers run though. If the command line compilers do work, a lighter installation option would be to incorporate them into Geany. An open...

    Programming Editor for MAC ?

    Any of the "Mac" options are likely to only work on pre Catalina Macs. A real pity that the software for macOS has not been popular enough for Rev.Ed to justify engineering a more up to date version. I've said before that one of the reasons I started with PicAxe was the cross platform...

    New Art / Study Project

    To offer a more useful opinion than just spotting old Windows wallpaper... If you are set on making your own PCBs, I'd look at a milling machine. I used to make PCBs for the college I worked at, on behalf of the students. Printing the PCB artwork on transparent paper then exposing this to...

    New Art / Study Project

    Not only a statue of Albert Einstein, but in the background a desktop image that looks suspiciously like 'Prairie Wind" from the days of Windows NT/XP/Server 2000. Good times...

    Servo linkage headache

    Lovin' that belt drive! It's a work of art. And the intricacies on the fuel lines. Motive sculpture is the only way to describe that. Beautiful.

    New Art / Study Project

    I've used a lot of '595 devices to sink current through some common anode 7 segment LED displays. I'm running these at around 10-15mA with a single resistor in the anode supply. The 595's have been totally reliable connected this way, and they have been in use for a number of years in a...

    Help needed choosing relays

    Does the motor have brushes? How many wires are brought out for connecting? Many 240V motors that can run on DC will run very well from 24V upwards. Sinclair famously used a series universal motor (AC or DC) in the C5 which ran off a car battery (or two). Try powering the motor (with no...

    Windows 7 alternative?

    When I was writing programs for Windows using Delphi, to install the .ocx the program required I always had to install it (and it's dependencies) with regsvr32. Just loading it from my main executable was never enough? Still, that was some time ago now, perhaps I could have called them in the...

    Windows 7 alternative?

    Indeed. I did so in post 76: Here's the link to the tutorial I originally used: https://picaxeforum.co.uk/threads/successfully-running-pe5-under-linux-wine.29702/

    Windows 7 alternative?

    Again, going from the original tutorial... Wave32.ocx is an activeX component. To use an activeX component, it needs registering within Windows, this is done using regsvr32. Wave32 seems to internally depend on a function or functions provided by mfc40.dll so if mfc40 cannot be found wave32...

    Windows 7 alternative?

    As I understand, mfc40 was one of the Microsoft foundation class files, could you install that into WINE? The instructions I followed came from a Linux user, I adapted them for Mac. Here's the link to the tutorial I originally used...

    Windows 7 alternative?

    Again, it seems I did get this (PE5) working: I succeeded by 'cheating'. I use WINESkin to create the WINE environments, after I'd created the PE5 environment, I did as possibly you did, by locating the C:\ drive, copying in the mfc40.dll to the Windows\System32 directory. I then opened up the...

    Windows 7 alternative?

    Under the guidance of @bpowell I got PE6 to run on my Mac under WINE, here's the items I had to install into the WINESkin to get it working: Many, many, many thanks Bpowell. I do now have the PE6 editor installed, under Wine on my Mac running OS X (10.9). I created a WineSkin, used as you...
