  1. Hello, Peter made an awesome video (4k quality!) demonstrating the assembly of the following modules Euroceiver (line driver receiver in the rack), power distribution A1 Expander (AOUT based on MAX5500) D1 Expander (DOUTX1 for gates plus protection) D2/D3 Expanders (likewise for clocks and triggers) Feel free to use this thread for any discussion or troubleshooting. Have fun building your modules!
  2. I have a few line driver PCB's left which a don't use. Included in the photo are the finished PCB's for reference. PCB's will be sold without components. A set (1 receiver PCB and 1 transmitter PCB) is €5. Shipping to most European countries is €4. If you're interested in buying a set let me know where you live and I can verify the shipping costs.
  3. I have seq v4 with wilba CS working fine. I add the line driver + aout ng modules connected by scheme for seq users from www.ucapps.de/mbhp_line_driver.html (j8/9 of core to j1 cs; j2 to j2 transmiter; j19 of core to j19 transmiter etc.) and in result have crazy seq.(screenshot) and MC3486, MC3487 seems warm. Check for shorts on line driver pcbs- all fine. Pinout seems normal. Some result without any connection fron transmiter. AOUT seems work fine. Tell me please where to look for error. Thank you.

  5. Hi Midiboxers, Line driver breakout CV /gates finished i used AOUT and a tweeked DOUTx4 and of course the line driver receiver! DOUTx4 is stuffed with regular 220 ohm resistors for leds indicators and UDN2981 for gate booster. UDN 2981 are directly linked at the outputs of 74hc595 (before the 220ohm resistors) . the gates assigned to CV have two UDN 2981 (input in parallel) one is powered by 5V (eurorack 5V gates) and go to minijacks and the second is powered by 12V and go to 1/4jacks (oldschool 12V modular gates) same for the extra drum triggers gates: 8 are in 12V and the last 8 are in 5V... need 1k resistor at each outputs of UDN for ground short protection !!!! 3 PSU inside: 12V for 12V gates, 5V one for the 5V gates /line driver receiver/DOUT/AOUT and bipolar 12V for AOUT. the 5V line from the seq is cut on the receiver. i could have used the same 12V from bipolar but a dedicated 12v make sense cause wanted the AOUT "stability" as usual i've got a bug : the CV 1 and 2 have the same problem: at calibration voltage are divided by 2... don't know why...not the ICs , no shorts, ( problem on the 2 first channel!) all other 6 channel working properly. the calibration "max" voltage is 4V on this two channel is it possible to be a log error? i build AOUT because i've got max525 in stock... is someone use this config and could confirm that line driver work with AOUT?
  6. YEAH! Weihnachten ist gerettet!! Muss jetzt nur noch jemanden finden, der sich um meine Kinder und Arbeit kümmert. Ich habe zu tun...
