After a long buoys (since January) has completed a draft of a micro-Covox. Its surface is smaller than SD cards. Helped in the production the first electronic (elect) scenes Candle - Sebastian Bartkowicz (made VBXE v2 or SoundBoard), and finish Epi - Adrian Matoga.
Although the distribution of pins is adapted to Aki-Stereo - upgrade might work with other stereo or individually.
Left = in the distribution. The right of it in conjunction with the Aki-Stereo (only as examle).
- for 800XL/1200XL/65XE/130XE/800XE (etc);
- Small size 39x17mm;
- Adapted to the connector-Stereo Aki (Part is in accordance with the order to go POKEY);
- DAC D / A - linear characteristics;
- Lm660 amplifier - output full range of 0V to 5.5V;
- Mix of channels to the socket TV / monitor;
- Operated on / off the aOSD configurator by Candle (or switch on the body);
- Low pass filter to 14kHz
(Or lower - but it makes cool effects though - change the sound by cutting output);
- The option to high pass filter - example 100Hz (not recommended);
- Suitable for powering 12V or 5V atarki with IOboard by Candle (no difference in sound quality).
- Control of the address $D5xx or $D6xx or $D7xx (etc)
History, which is why for so long ....
ver A. go silly mistakes
ver B. add to DAC to PCB and the bad song
ver C. I do see on the PCB or iron bad
ver 1. professional board and .... Test show that the decoder 138 is to slow.
ver.2. but with a different decoder, amplifier only change the lm324 on lmc660 and plays better
ver 3. the final plate, the other power DAC and play as in the example, additives that plate was the universal
and here is fotos:
And how is a game you have examples here in mp3 and listen to the NeoTracker'em (lies on ftp.pigwa):
1. JestSetWilly_uCovox.mp3 and version JetSetNeo.neo
2. Enigma_uCovox.mp3 and version Enigma.mod
3. RSI_Hard_uCovox.mp3 - Guitar plays beautiful
4. Sauron_uCovox.mp3 - the best of best MOD
5. Btr_uCovox.mp3 - cool !!
6. Near 30 seconds 12 collate MODs
8. Music of different length (NEO file format)
9. Undreams_uCovox.mp3 to regret not listen
10.Troddlers3_uCovox.mp3 ach ta sielanka
11.TheRose_uCovox.mp3 playing on the waiting
12.Techno_uCovox.mp3 very cool!
My rating - I can not hear the differences when comparing with other versions Covoxs. Small nuances of merit for the converter to the characteristics of linear (and not step in the government as resistors). The potential could go at a faster CPU - 65816. And that time will tell.
Why is that?
Because a lot of people have Aki-Stereo, and are deprived of Covox - comparing a set of SimpleStereo.
I felt obliged Candle and only knows how many sacrifices it cost me.
And how much?
The price includes the cost of making prototypes (only the third was a hit). This, too, that the cost of the mustard oil, you can now ....
Plate (we goldpiny exits) to
17.50 USD or 12.50 EURO or 10.50 GBP
+ shipping to Europe or North America = 5.50 USD or 4.00 EURO or 3.00 GBP
Bank transfer or PayPal
My paypal address is email@example.com
Deadline of realization 24 days near vacations have
You pay for it exactly (certainly without coin):
How much is hidden in this uCovox
What is now?
They are in sales, you can order / pay
