    LabGear 6+1

    The amp came with a terminator fitted to the 'main' port .. no idea if it's 75ohm or not.

    LabGear 6+1

    That was what I assumed - Distribution signal is at optimum level. I can't plug lead in direct due to location

    LabGear 6+1

    I have my incoming aerial feed connected to a LabGear LDA2061 distribution amp. All TVs connected are working, but if I check signal strength - not that high : From Kilvey Hill Transmitter 21 strength 40% 22 40% 24 36% 25 38% 27 42% 28 42% 34 22% Quality states as 100% on all. Should I be...

    Getting hold of hardwood

    I often see posts on people selling cutting boards or similar made of glued-up strips of hardwood ... Maple, Acacia, Cherry, Walnut I's like to make a couple of these in a custom size. Anybody know of a good source for such woods, my local timber merchants have loads of structural materials...

    Flat bottom drill bits

    I thought of that, but forstner have only cutting face. One I was thinking of have normal flutes like a twist drill, but flat cutting face with a centre Brad point. Nearest I have found is a dowel drill

    Flat bottom drill bits

    I need to drill some flat bottom holes in hardwood. (12mm diam) Ones I used previously are a bit like engineering end mill bits. Is there a particular name for these bits …. So I can find one on-line.

    1.5" fluorescent tube fittings

    A neighbour just donated me 2 VGC twin 6' fittings complete with Phillips 75-85W tubes, While I have the slimline tubes & fittings in my garage, I could utilise these over my workbench. Should I just use as is .... or is there an adapter to use slimline Tri-Phosphor tubes, I can see an adapter...

    Lining of boxes

    want to have as thin a 'protection' as possible

    Lining of boxes

    Often instrument cases are made of wood , but have a black 'felt' coating over all the compartments to protect the instruments .. Typical (but old) such case in sample pic Is this 'sprayed on' or is it a glued on fabric ? .... need to make a few storage boxes and need to have them lined...

    Voltage & switch state identification project

    If you don't like my post please feel free to scroll on by, there is no need to be discourteous or insulting this is an open forum. I am not clueless, the sketch is done using what I have to hand, (PowerPoint), I don't have access to an electrical drawing package to produce using IEC 60617...

    Voltage & switch state identification project

    Others have understood the ask ... apologies if you are not understanding or possibly reading too much into it. The fan is fully controlled by the controller, the output of which is 0 to 12V, and as its variable speed it can be any voltage up to 12V ... I have measured and at full speed it is...

    Voltage & switch state identification project

    I could not bother with the LM393 comparator … and instead use a simple 741 op amp

    Voltage & switch state identification project

    Taken suggestions onboard Now it looks like this sketch I know I need to use current limiting resistors for diodes ... not sure if I need any diode protection for relays, normally add an IN4148 across the coil. Existing physical switches are unchanged just now driving relays as per suggestion...

    Its DC 0 to 12V

    Voltage & switch state identification project

    need it to activate display from 1V to 12V ... hence a comparator was my thought.

    Voltage & switch state identification project

    Agree and I could use a fixed 12V for the relays, that would resolve switch issue, still have to detect that there is voltage to fan …. And that can be anything from 0 to 12V I thought of a voltage parameter … but happy if a simpler way.

    Voltage & switch state identification project

    It’s on the sketch …. The controller is not important, it provides a power voltage as explained … 0 to 12V to the fan This feed is a simple 2wire output, with the 2 switches in series. i would like to be able to know when there is any power feed to fan plus the state of the 2 switches

    Voltage & switch state identification project

    Project I would like to identify the state of 3 switches, sw 1, 2 & 3 and when power is supplied to a fan …… so 4 indicators – assume these would be LED. I.1 – I.4 Sketch is attached. The controller is self-contained controller providing Bluetooth, Wireless, time & temperature functions...

    Dowels for reinforcement ?

    It was quality glue, and pressure on joints for 24 Hrs. So you may be right.

    Dowels for reinforcement ?

    I was thinking dowels would help hold the 2 halves of handle together, if it won’t them I’ll not do it. I do make my own dough, several types of it. plus Nan bread, pitta bread etc.
