Went today to the electronics shop to get some cheap stuff for the yusynth and saw this box for 6 euros. From what you can see, I got it. It is relatively small with a panel area of 15×9cm. So I went on to repackage my avrSynth16 I had build sometime ago. There was a failed attempt [...] This is an octal RGB clock. I made it so it can be impossible to actually tell the time but nevertheless its beautiful (in its own way). There is an atmel AtMega8 µCU and 6 RGB leds. Two for hours, two for minutes and two for seconds.Each led can be Red, Green, Blue, or a combination [...] To start, I had to make the array permanent and to such dimensions so as to have even lighting all over the surface of a typical photo-resistive PCB. So I laid them as shown, taking into account the distance of the leds which was enough to have overlaping beams of all leds. (so no [...] This is a test:) I had to make an array of UV leds and calculate properties. I made a simple excel file (openoffice format) to calculate these things here . Not exactly synth-DIY but this is a timer I made for my soon-to-post PCB oven. You just set the time and keeps track of it, switching it off when it must and securing it from accidentaly opening the lid, saving my eyes from UV burn An old project of mine (6-12-2008) was to have a counter run through a series of voltages and make a waveform out of it. There is a pulse generator and a counter at the bottom part of the breadboard and decoders at the top. It never worked right so it was dropped. I tried [...] Got a PIC (microchip.com) programmer off ebay (I wonder what I would do without ebay here is its anthem). It is a el-cheapo clone, (cheapest USB programmer I found) able to programm only 8-bit microchip.com microcontrollers (such as the 16f84 and 16f877 and 18f452 that the good guys at microchip.com sent me as samples). I [...] |
