About me

I’m an old “analog” guy that has worked in the chip industry for decades. My garage time is spent fixing stuff, and building other stuff. Some projects are electronics related, while other bits are machine (i.e. mill, lathe, weld) related.

  1. I have a V10-P and ant to upgrade the push button switch array. I see the switches on your machine have been fix already. I would appreciate any information you can provide about your conversion. My machine is 115 V, 60 Hz, single phase.


    • Hi Jim – I don’t think my wiring will be applicable to your case because I’m using a VFD and 3-phase motor. All the controls you see in the box are low voltage controls that go to the VFD.

      There is a switch conversion discussed on the Yahoo Maximat group. A diagram is posted in the files section by a gentleman named Andy Nobbs.


  2. Yes your nice conversion won’t work for me now, but thanks for taking the time to reply. I have found Andy Nobbs info on the Yahoo site and it should prove to be helpful.



  3. I have a Bose L1 model 1 , the base is not working , can you repair this base ?
    please contact me if is possible…
    Thanks so much


  4. Hi, I have a Bose L1 model 1 System which doesn’t power up. Would you be able to have a look at it for us? Thanks.


  5. Hi there Len,
    I totally enjoyed reading about your Philips 212 Turntable upgrade, that was the first turntable that I ever owned and I have been planning to build a Phono Listening setup using a Kenwood KA-3500 amp I have and a Philips 212 Turntable. I have been able to pick up 2 Philips 212 turntables (1 to restore and 1 for any parts I may need) however, I didn’t need any steal any parts from the donor turntable, so I was thinking of using it and doing the Arduino conversion on it. I see that you had a total of 5 controller boards made and wondered if you would be willing to sell me one of them if available? I’m sure I will have questions to pick your brain with along the way also. Thank You Sir.


    • Hi Johnie – Yes. I still have boards. I can send you one for $10. I still have parts so, if you want, I can stuff one, minus the Arduino, for another $40. If you’re in the US and don’t mind slow mail, I’ll take care of the postage. I just have to figure out how we can contact. I don’t want to broadcast my phone or email here. I’m trying to figure out how to put a private mail link in a WordPress blog.


      • Hi Len, great to hear back from you, and great news that you have extra boards for the 212 project, and I will certainly take you up on the offer to stuff the board for the additional payment. I am in Los Angeles, You can contact me at munchkin17@gmail.com and we will pick up the conversation from there. Once again, great to hear back from you and we’ll speak soon. Johnie


  6. Hi Len,

    I am looking to build a Touch DRO setup with glass scales for my old Bridgeport and I see you have done that. Looking at the schematics you published a few years ago, I see your setup did not use the TI Launchpad. How did you flash the MSP430? Can you flash it via the bluetooth connection from a laptop?

    Best Regards,

    Kenny Logsdon


  7. Hi, Len — Nice piece on the Philips 212. I have one from 1971 with two of the issues you talked about: The on-off switch sticks, and the turntable plays at 45 only, with both the 33 and 45 lights going at the same time. The bulbs themselves work fine, and were replaced new around 1999. The turntable has not been used since. Would you like to have it free so you can take those scarce bulbs and other parts from it? I’m in Monterey, and you mentioned you live in the Bay Area, so I could bring it to you. Let me know if you’re interested. Thanks! Jeffrey


    • Hi Jeff – I would be thrilled to get a “donor” 212. I’ve sent a few boards to people, but I can’t send them fully built boards because some parts have to come off the TT. If I had a donor, I could send a complete board first and have them send back the old one when they do the swap. I haven’t figured out how to have private conversations on WordPress, but as a workaround you could send me your email in a comment that I will NOT approve so it’s not made public, then I’ll contact you directly. Thanks.
