I was looking at such ovens and pizza ovens before I thought "nope" and just bought a proper oven :lol:
Where's the fun in that? :D

Re: Smonson's poorly-thought-out toaster oven reflow experiments

Interesting, I had been considering a reflow oven based on something like this, but with some micro-controller based Ben Heckery added for temp control and timer. Would be nice to at least have a pre-heater for hot air based reflow activities. Great minds think alike! I have a stainless steel therm...

Re: Smonson's poorly-thought-out toaster oven reflow experiments

The following weekend (this one just gone) it was time to try real soldering. I used a little too much expired solder paste to place a resistor on an old HDMI mod board and chucked it in! After guessing where to turn the dial for the perfect reflow profile, I got a result. toaster-reflow7.jpg Next i...

Re: Smonson's poorly-thought-out toaster oven reflow experiments

My first thought was "I should melt something!". So I scrounged up my bag of old solder-contaminated crud that I've scraped off my workbench and soldering iron sponge over the last 20 years and threw that onto a tray. toaster-reflow3.jpg After switching on the oven, a large cloud of toxic smoke eman...

Smonson's poorly-thought-out toaster oven reflow experiments

Yep. Me again with another hare-brained scheme. :dizzy: I impulse-bought one of these $29 ovens at K-Mart and decided that the almost impassable mountain of junk in my garage could be bigger. toaster-reflow.jpg It is packed with features: Low flammability sheet metal construction Dial goes all the w...

Volunteering to test a prototype if possible :geek:
Well I'm only planning to make a few of these, since it takes a long time to build them by hand. I'll keep you on the list :)

Re: Display brightness in ST emulators

As far as I remember from owning an STFM a long time ago, but it's normal for the 9-bit palette to look a bit 'duller'? It's relative. It may be duller than another device plugged into the same monitor, because it is down to an absolute voltage that is applied to the video signal - but that brightn...

Re: Display brightness in ST emulators

Exellent work investigating and diagnosing this! Having gone through similar thoughts for the HDMI mod (since it outputs 8 bits per colour), in my opinion the ideal solution is to repeat the palette bits without gaps, i.e. for each colour, a 3-bit brightness represented by bits 123 (for STFM) should...

Re: Sidequest: VGA scan doubler

Thanks @sandord! Graphing it like that makes it a lot easier to see the progression of colour, and it's not as bad as it could be :)

I think that's the last thing I was going to add to the FPGA code... I guess that makes it a final prototype.

Re: Sidequest: VGA scan doubler

I wanted to add a scanline effect to the 'doubler, since a lot of people want to recreate the authentic mid-80s feel when they look at their Atari screens. Having anticipated doing this, I put 2 jumpers on the board, with one being for the scanline effect, and one spare one. For the HDMI mod, it's a...
