    Gardner Denver wire wrap guns

    Hello, This isn't your model but shows the basic operation of inserting the tools for wrapping. Jump forward to 1 minute in....Otherwise a very boring intro. Martin

    What???

    Sounds like perfect 'Chinglish' translation to me. "It is the record of mutifunctional tool"... .."Deep water exploration". Looks like you have a Swiss Army Camera! Made in China!. Martin

    New guy just getting started need advice on tools

    Hi Billy, You could ask some universities or colleges. They might even donate one to you! "Disabled vet" can have it's advantages... Also check craigslist. I don't know if the states have "Freecycle". But there are some great freebies to be had. Old scopes are usually very heavy and the postage...

    Strange PSU Problem

    Hi Danno, On anything that old, the caps could be the problem. Tack another one to the under side of the board to see if it solves the voltage problem. Martin

    LED power supply help

    That's good news.. But for other little circuits! Have a medium backup.... I only have 25 CD4017's because they were £1.79 all in including delivery!! Keep me posted please! The circuit does work, I bread broaded today. The flash rate might still be a little too fast, or not not on long...

    Miniature chandelier wiring

    Well, seeing as they have a maximum current limit too of 55ma, two in series as my pic above and 100 ohm resistor on each string should be fine. Martin

    Miniature chandelier wiring

    Hi zzzach, Looks like you have them all connected in parallel, and yes all getting 9v. Probably better to wire them 2 pairs in series. 4x3=12v you only have 9v. What 'lights' are they? Martin

    Audio Amplifier CCT5801 no datasheet - unable to find datasheet - help appreciated

    Hi Berninia, Why can't you just send Left signal to Left unit and Right to Right? If the IC hasn't got two signals, it can't mix them. Put a stereo lead to one unit using only one channel, and then connect second unit via the other channel. Martin

    LED power supply help

    Hi Ian, Sorry, I spent the weekend at my sisters. I don't personally use online suppliers apart from Ebay unfortunately. But you have RS components and Farnell UK which I believe is something to do with Element14. The best I can do for you is send you all the components needed from my stock...

    Any way to check D1889 & B1340 transistors, apart from measuring resistance?

    Hi Bross, Use this website to find equivalent transistors. http://alltransistors.com/transistor.php?transistor=9753 I don't know why you're having trouble finding them! You're only in Spain, not Tim Buk Tu!. Martin

    LED power supply help

    Hi Ian, C2 and C3 are 100n (104 ceramic disk caps) 0.1μF. Picture here. The VR is up to you. You can set and forget or have a small hole in box to adjust or use a large pot. To be honest with you Ian, if you don't have components laying around it could get expensive. Also, you may need to...

    Motor speed control

    I feel your pain, but the reality is make it or buy it! Some prefer to make with no comprehension of cost, others buy because of cost! Your call... Martin

    Motor speed control

    I was going to suggest larger pulleys. But the RPM is quite high. Several pulleys would be needed. But my math is useless to work it out. That's why I called "the motor expert". Martin

    Tic Tac Toe, Human vs Machine using flip flops

    Hola Senor, So what have you done so far? How can anybody help you make it smaller, if they don't know how big it is? I also think this is posted in the wrong section. Tambien, nadie se puede dar respuestas del colegio! Solo ajudar! EDIT: Any tip to make circuit smaller? SMD! Martin 'o' Martinez:p
